Topsoe’s sustainable SNOX™ emissions control technology enters the carbon black industry  

April 12, 2018 -

Orion Engineered Carbons LLC has signed a contract for Topsoe’s sustainable flue gas cleaning technology, SNOX™.

The contract has a value of a three digit million DKK amount.The solution will remove SOx, NOx and dust particles from tail gases at Orion’s carbon black plant in Ivanhoe, Louisiana, USA.

It is the first time that SNOX™ is applied in the carbon black industry. 

Since 2014, Orion has conducted in-depth analyses of the SNOX™ process, including investigative site visits to existing Topsoe plants and testing the concept at one of Orion’s manufacturing facilities. In particular, Orion was convinced by the second-to-none sustainability profile of SNOX™, which does not consume any reagents, apart from ammonia for the NOx reduction, and does not consume any water. Other factors that played a major role in their selection were the highest available energy efficiency and the very low emissions level that meets the stringent environmental regulations. The agreement with Orion includes engineering, license, proprietary equipment, spare parts, catalyst, and future supervision tasks during commissioning and start-up, as well as service obligations during commercial operation. The SNOX™ plant is scheduled to be in full commercial operation by April 2021.The SNOX™ process removes sulfur dioxide, nitrogen oxides, and particulates from flue gases. The sulfur is recovered as sellable sulfuric acid and the nitrogen oxides are reduced to harmless free nitrogen. The process is based on catalytic reactions and does not consume water or absorbents. Neither does it produce any waste. 
The heat generated in the process can be reused to preheat air in Orion’s process which improves overall efficiency and economics considerably. 

Two Andhra Pradesh port towns in race for HZL smelter 

March 29, 2018 - The port towns of Kakinada in East Godavari and Krishnapatnamin Nellore district are in the reckoning by the Vedanta group to set up a zinc smelter. The smelter will be set up by Hindustan Zinc Ltd, the flagship of the Vedanta group in India, and the project was announced during the CII Partnership in Visakhapatnam last month.  According to J. Krishna Kishore, chief executive officer of Andhra Pradesh Economic Development Board (APEDB), HZL had sought 1200 acres of land for setting up the smelter. “The company indicated that it wanted the land in port towns, so the board showed Vedanta officials several large parcels of land in Kakinada and Krishnapatnam,” he said.  Asked when he expected to hear about which town Vedanta would be setting up the smelter, Krishna Kishore said the potential of the two towns is stated to be under consideration by the board of HZ, and that a decision is expected “shortly”.  The Anil Agarwal-owned Vedanta Ltd has a 64.92% stake in HZL, while the central government owns a 29.59% stake, and the balance is held by mutual funds, financial institutions and individual shareholders as of 31 December 2017, as per the company’s filing with the bourses on its shareholding pattern.  Krishna Kishore said that HZL is expected to invest Rs. 3000 crore in the first phase of the smelter, with another Rs. 3000 crore in the proposed second phase.  “Apart from the zinc smelter, HZL is also planning to set up a fertilizer plant to make use of the sulphuric acid generated by the zinc smelting process. The fertilizer plant could be outsourced to a third party by HZL, but that is something HZL will take a call on when the smelter is commissioned,” he said.  The current plan by Vedanta to set up a zinc smelter is the second attempt by the non-ferrous conglomerate to make a success of such a manufacturing unit in Andhra Pradesh. Its first attempt ended in the closure of the existing zinc smelter in Visakhapatnam in 2012.  The Visakhapatnam zinc smelter began commercial operations in 1977, and it produced both zinc and lead, and silver as a byproduct. While HZL shut down its lead plant in Visakhapatnam in the mid-nineties—long before Vedanta acquired a majority stake in the company from the government—following complaints by residents of villages adjoining the smelter that the lead residue was leaching into their groundwater sources, the company shut down its zinc smelter in 2012 with HZL and Vedanta claiming that it had become unviable to run the plant by transporting zinc concentrate from its mines in Rajasthan and elsewhere. Over 300 executives and workers were let go off when the Vizag smelter was shut down.  Last year, HZL hired a consultant to find a buyer for the 342 acres of land on which the smelter is located, but the move was moved into cold storage after labour unions in Vizag raised concerns over HZL’s plans to book windfall profits from the sale of the land, which is in the Gajuwaka neighborhood. The 342-acre HZL land is estimated to cost nearly Rs. 5000 crore.  Vedanta now plans to convert the land into a “city centre project”, as announced by the company during the partnership summit last month, and confirmed to ToI by HZL spokesman Pavan Kaushik earlier this month.  Krishna Kishore said that HZL’s new smelter in Andhra Pradesh would be using imported zinc concentrate, which had made it imperative for the Vedanta group to locate the plant in a port town. 


Fluor awarded FEED contract for Egyptian phosphoric acid production facility

March 27, 2018 - Fluor Corp. has announced that it has been awarded the front-end engineering design (FEED) contract by Enppi – Egypt’s state energy firm – for the offsites and utilities section of the main plant complex and support services for the Waphco phosphoric acid production plant at Abu Tartour, New Valley province, Egypt. 
The President of Fluor’s Mining & Metals business, Tony Morgan, said: “Fluor appreciates the importance and relevance to Egypt of this major industrial project and will use its experienced resources and subject matter expertise to deliver this complex engineering project to meet our client’s goals.“Our integrated project team is one of the most experienced in the mining and fertilizers industry with the resources, expertise and knowledge to meet the cost, safety and fast-track schedule needs of our client.”Fluor will work with Enppi as an integrated team. It will fast-track the FEED for the plant, which will utilise resources from the Abu Tartour mine to produce merchant-grade phosphoric acid. The project scope includes all process facilities. These include a sulfuric acid plant, utilities with a cogeneration system, storage and other required units. Once the facility is completed, it will produce 500 000 metric tpy of wet process phosphoric acid.

DuPont increases catalyst prices

March 7, 2018 - DuPont Clean Technologies (DuPont) has announced a general global price increase of US$0.50/l for its MECS® sulfuric acid catalyst products. Subject to the terms of applicable contracts, the new pricing will take effect immediately.  Our world-leading, high-quality catalyst enables customers to achieve high yield sulfuric acid production with maximum efficiency and reliability,” said Cristina Kulczycki, global product manager, Acid Catalysts. “Our focus continues to be on supporting members of the sulfuric acid industry with new products, technologies and services that allow them to be more agile, flexible and competitive.”

World’s largest wet gas sulfuric acid plant officially starts up
February 19, 2018 - Bestgrand Chemical Group has announced the successful startup of its wet gas sulfuric acid (WSA) plant. 
The plant has a production capacity of 300 000 tpy of sulfuric acid, and is the world’s largest such facility. It will treat 131 000 t of acid gas over-the-fence per year from the neighbouring world scale refinery plant operated by a joint venture (JV) between China National Offshore Oil Corp. (CNOOC) and Shell in Huizhou City, China.Bestgrand Chemical Group claims that it focused on the environmental benefits from using WSA to capture gaseous sulfur and convert it into commercial grade sulfuric acid. It has also been a deciding factor that both the energy efficiency and the heat recovery of the process are very high. The company predicts that it will decrease CO2 emissions by 220 000 tpy and SO2 emissions to a level that is 50% lower than that required by the sulfuric acid industry.Frank Lei, Senior Sales Director, Topsoe in China, said: “Haldor Topsoe is proud to be awarded the license, engineering design, tech service, and hardware and catalyst contract for the world’s largest WSA plant by Bestgrand Chemical Group. The successful startup is a milestone for the WSA technology both in China and globally, and it proves that this technology has an important role to play in reducing harmful sulfur emissions in a commercially sound way.”Since 2000, Topsoe has sold a total of 68 WSA plants in China. 54 of these are now on stream, with the remaining 14 under construction.

New Projects Boost Iran's Copper Sector


February 5, 2018 - Thirteen expansion projects of Kerman Province’s National Iranian Copper Industries Company were inaugurated late Thursday by President Hassan Rouhani and Minister of Industries, Mining and Trade Mohammad Shariatmadari.  The total value of the projects exceeded 35 trillion rials ($760.8 million), the Iranian Mines and Mining Industries Development and Renovation Organization announced.  NICICO is the leading copper producer in the Middle East and North Africa region, as the mines it operates hold close to 14% share of Asia’s copper deposits and about 3% of global reserves.  Iran holds about 4 billion tons of estimated copper reserves, according to Geological Survey of Iran.  The new production projects include a flash smelter with a capacity of 282,000 tons of copper anode per year alongside the purchase of casting wheels and anode furnaces with an investment of 2.4 trillion rials ($51.6 million) in addition to €182 million; Khatunabad Copper Smelter with an annual capacity of 200,000 tons of copper cathode and an investment of 640 billion rials ($13.7 million) in addition to €143 million; Sarcheshmeh copper plant’s new convertor furnaces’ gas discharge system with 1.54 trillion rials ($33 million) in addition to the investment of €19 million; Sarcheshmeh cathode washing system with 1 trillion rials ($21 million) of investment; Sarcheshmeh’s explosive material production plant with a capacity of 12,000 tons of gelatin dynamites per year with 120 billion rials ($2.5 million) of investment; and expansion of Sarcheshmeh’s sulfuric acid plant capacity to 300,000 tons per year with 580 billion rials of investment in addition to €3 million.  The new infrastructure projects comprised the second line of the 80-kilometer Sarcheshmeh-Shahr-e-Babak Road with an 800-billion-rial ($17 million) investment; the first and second phase of Sirjan’s 500-megawatt combined cycle power plant with an investment of 700 billion rials ($15 million) in addition to €285 million; Khatunabad’s new copper concentrate storage with a 60,000-ton capacity and a molybdenum dewatering, drying and drum-filling plant, with a combined investment of 790 billion rials ($17 million); increasing the capacity of quicklime storage by 1,250 tons with an investment of 110 billion rials ($2.3 million); Meymand-Shahr-e-Babak electricity substation with 50 billion rials ($1 million), in addition to an investment of €15 million; and nine electricity substations to feed flash smelters, acid sulfuric and molybdenum plants with 480 billion rials ($10 million) of investment, according to NIOC's website.  The company, however, stopped short of saying whether the projects' "inauguration" meant that they have become operational or simply that work has just begun on them. 

Giant Holding
 

NICICO operates the world’s second largest and the Middle East’s largest open-pit copper mine, Sarcheshmeh. The mine is home to over 826 million tons of proven and 1.2 billion tons of estimated copper reserves, alongside substantial amounts of minerals such as molybdenum, gold and rare metals.  NICICO's other mines include Sungun Copper Mine in northwestern Iran, Taft, Miduk, Chahmesi and Chahfiroozeh mines in central Iran, Daraloo Mine in the south and Chehelkoureh Mine in southeast.  Its plants in Kerman Province include Sarcheshmeh and Miduk concentration plants with 800,000 tons/year capacity, Sarcheshmeh Molybdenum plant with 7,000 tons/year, Sarcheshmeh and Miduk SX-EW plants with 13,000 tons/year capacity, Sarcheshmeh and Khatoon Abad smelter plants with 250,000 tons/year capacity, Sarcheshmeh Sulfuric Acid Plant with 100,000 tons/year capacity, Sarcheshmeh Refinery Plant with 240,000 tons/year capacity, Khatoon Abad Refinery Plant with 200,000 tons/year capacity and Sarcheshmeh wire rod, slab and billet casting plants with 180,000 tons/year capacity.
 

Stability in Global Prices
 

Capacity expansions at NICICO have come at a good time, as global copper prices are holding their own in 2018.  After a series of plunges in late 2017, copper spent most of December growing rapidly to distance itself from its $6,500 lows and jump above $7,000 in January 2018. Prices have taken a beating since the year began, dropping from a high of $7,202 to just above $6,900, but February showings have been strong and it’s now again above $7,100, London Metal Exchange reported.  NICICO’s experience with the historic lows of 2015 has made it more resilient and also adaptive.  According to the head of IMIDRO, Mehdi Karbasian, NICICO has reduced its copper concentrate finished price from 35,510 rials (76 cents) per kilogram to 24,400 (52 cents) and cathode prices from 51,980 rials ($1.1) to 39,000 rials (83 cents) in the past four years.  The cost-cutting enabled the company to survive the low prices and now with the markets improving, it is poised to increase NICICO’s competitiveness.  NICICO’s shares are currently being traded at 2,633 rials each on Tehran Stock Exchange with a market capitalization of $3.47 billion.  The company is a semi-privatized entity, as a large number of state-owned firms or other semi-privatized companies own its shares. Its largest shareholder, for instance, is the vast mining governmental holding IMIDRO with a 12% share.  Bank Mellat, Metal and Mines Development Investment Company are the two other, each owning about 5.7%.


Outotec to deliver modular sulfuric acid plants for Shalina Resources in the Democratic Republic of Congo

January 29, 2018 - Outotec to deliver modular sulfuric acid plants for Shalina Resources in the Democratic Republic of Congo Outotec has been awarded a contract by Shalina Resources Limited for the delivery of advanced sulfuric acid plant technology to the Mutoshi project near Kolwezi in the Democratic Republic of Congo.

"We really look forward to working with Shalina Resources in the Mutoshi project, and are extremely pleased that we can complete our diverse technology package for the copper and cobalt processing now with sulfuric acid plants. These modular plants represent our latest technology, and remarkably improve the environmental performance of the plant", says Kalle Härkki, head of Outotec's Metals, Energy & Water business.

Rio Tinto lifts force majeure on copper, acid from U.S. mine


January 26, 2018 - Rio Tinto lifted force majeure on Jan. 1 for shipments of refined copper and acid from its Kennecott mine in the United States, 79 days after declaring it could not meet customer commitments, a spokesman said on Friday.  The global miner declared force majeure October 13, after halting production of refined copper at its Utah mine smelter following the death of a worker exposed to sulfur dioxide gases at the plant. It restarted the smelter November 17.  “It’s business as usual,” said spokesman Kyle Bennett.  In the fourth quarter, refined copper production at Kennecott declined 67 percent compared with the same period in the previous year, to 22,100 tonnes from 67,000 tonnes, Rio said in an operations report last week.  The smelter was expected to draw down an increased concentrate inventory during the first half of 2018, Rio said.  In 2017, Kennecott produced 125,800 tonnes of refined copper, down some 20 percent from 2016. 


Smelting company Nyrstar has opened its upgraded facility at Port Pirie, north of Adelaide

January 22, 2017 - Smelting group Nyrstar has opened its upgraded metals processing plant at Port Pirie, north of Adelaide, after a $600 million investment to cut pollution and ensure its long-term viability.Premier Jay Weatherill says the upgraded plant has secured 730 ongoing jobs and will allow the company to significantly reduce emissions."For Nyrstar, improved efficiencies provide a pathway to uplift earnings and for Port Pirie we can lock in better health and environment outcomes for decades to come," Mr Weatherill said as he visited the plant on Monday.Nyrstar chairman Martyn Konig said the smelter had played a strong role in the changing face of Port Pirie for more than 127 years."Nyrstar is proud and committed to continue to be a fundamentally important part of the economic and social landscape in Port Pirie," he said.Mr Konig said Nyrstar also valued a commitment to sustainability and one of the most important reasons for the redevelopment was the significant environmental benefits it promised to deliver.That included moving to a completely enclosed furnace design to capture dust and sulphur dioxide emissions which would result in a markedly improved environmental footprint, he said.SA Treasurer Tom Koutsantonis said the Nyrstar development had also provided up to 600 jobs during the construction phase and local companies were awarded contracts worth about $90 million."But just as importantly, securing the future for Port Pirie has encouraged other businesses to invest in new developments due to the certainty we have created," he said.Mr Weatherill said without the redevelopment, the closure of the Port Pirie facility had been a possibility.'That would have been catastrophic on a number of levels, environmentally, socially but of course economically for this region," he said.The premier said the government had two key goals in supporting the project, protecting the health of the local community and protecting local jobs.

Noranda Income Fund Provides an Update on Production

January 19, 2018 - Noranda Income Fund (TSX:NIF.UN) (the “Fund”) provides an update to the market on the work towards returning to normal operating capacity following the ratification of the new collective agreement on December 1, 2017.All active unionized employees returned to work at the processing facility in December 2017. As of the end of December, all equipment that had been idled since February 2017 has been restarted. By the end of January 2018, the Fund’s Manager expects to have completed the ramp up of the processing facility’s operation to normal operating capacity.Once the processing facility has achieved its normal operating rate, and assuming full supply of zinc concentrate, the Fund should be able to produce between 250,000 and 260,000 tonnes of zinc from the treatment of concentrate feeds as well as processing the 20,000 tonnes of Glencore Canada-owned cathode in 2018. As disclosed in November 2017, the Fund sold 20,000 tonnes of zinc cathode to Glencore Canada. It is expected that this material will be tolled by the processing facility. In exchange, the Fund will receive a tolling fee.The Fund, through its Independent Committee and their advisors, is currently negotiating with Glencore Canada and anticipates reaching a satisfactory agreement regarding the supply of zinc concentrate following the end of the current concentrate agreement on April 30, 2018.
