| General | PVS
Chemicals Belgium is a member of PVS Chemicals, Inc., headquartered in
Detroit, Michigan, USA. PVS Chemicals is a global manufacturer, distributor
and marketer of chemicals and transportation services. Its core businesses
include sulfur products, hydrochloric acid, water treatment chemicals,
full-line chemical distribution and minibulk distribution. The
company’s solutions are used by a wide variety of industrial sectors,
ranging from electronics, manufacturing, steel and agriculture to
pharmaceuticals, metal finishing, water treatment and food processing. PVS
Chemicals was founded by Floyd A. Nicholson in 1945 under the name Pressure
Vessel Service (PVS). The company founder established a set of guiding
principles which are known as the Nicholson Nine and which are as valid
today as they were more than six decades ago. The first and most important
of the Nicholson Nine is ‘Safety is #1.’ “We perform all activities in
a manner that protects and promotes the health, safety, security and welfare
of fellow workers, the community and the environment,” explains Jim Lawson,
general manager of PVS Chemicals Belgium. “We take personal responsibility
for our goal: no accidents, injuries or environmental incidents.” In
addition, the efforts of PVS Chemicals are guided by a commitment to
Responsible Care®. Responsible Care® offers an integrated, structured
approach to driving results in six key areas: community awareness and
emergency response, distribution, employee health and safety, pollution
prevention, process safety, and product stewardship. “Over the past
several years, Responsible Care® has contributed significantly to improving
our environmental, health, safety and security performance,” says Mr.
Lawson. When the company was founded 69 years ago, the initial focus
of PVS Chemicals was on cleaning boilers and pressure vessels. In the 1950s,
the company entered the chemical industry and started expanding its product
base. In 1975, PVS Chemicals opened its first subsidiary abroad in Canada.
Europe followed 22 years later. “In 1997, PVS acquired a sulfuric acid
manufacturing plant in Ghent, Belgium,” states Mr. Lawson. In 2001, the
group expanded to Asia and acquired a chloralkali manufacturing plant in
Thailand. Located in metropolitan Bangkok, the plant serves Southeast Asia
with chlorine, sodium hydroxide, hydrochloric acid, sodium hypochlorite and
other related products. Today, with international operations in
Belgium, Canada and Thailand, PVS Chemicals has annual sales of over 600
million USD. Located in the harbour of Ghent, PVS Chemicals Belgium is
specialized in sulfur-based chemistry. The company’s main products are
ultra-pure sulfuric acid, chlorosulfonic acid, sodium bisulfate, sodium
bisulfite, ammonium bisulfite, oleum and all grades of sulfuric acid.
“We are a sulfur-burning facility that produces higher-value sulfur
derivatives such as sulfuric acid,” explains Mr. Lawson. “Sulfuric acid is
the most widely used chemical commodity behind water. But we focus on high
added-value solutions. Our strength is in managing and manufacturing
products in the mature end of the life cycle, such as for applications in
the electronics and semiconductor industries or in food processing, water
treatment and industrial manufacturing. In these industries, our sulfur
solutions are used for higher-quality materials to minimize freight costs or
allow a higher return on investment, for instance.” “We are a

customers all over Europe. One product is sold all over the world, however:
sodium bisulfate, which is used for swimming pool applications. With 40
employees and annual sales of 20 to 25 million EUR, PVS Chemicals Belgium is
a rather small player in the European sulfuric acid market. Focused on
profitable product niches, it is a very successful one, though. “In
some sulfur derivatives, we are one of only two suppliers in Europe,” says
Mr. Lawson. Its small size and nimbleness make PVS Chemicals Belgium highly
adaptable to individual customer demands. “We can transform sulfur into
anything special required by the customer,” states Mr. Lawson. PVS
Chemicals Belgium also distinguishes itself by its capability of supplying
ultra-high purity products with impurities of just a few parts per trillion.
The company is also the only European supplier whose products are approved
by KIWA, an international certification organization. “KIWA approval
means that our products have been tested, evaluated and found to comply with
drinking water regulations,” explains Mr. Lawson. In the coming years, PVS
Chemicals Belgium will continue developing customer-specific sulfur-based
solutions. At the same time, the company will focus on improving the
manufacturing plant’s reliability and efficiency to further enhance customer
satisfaction.

October 27, 2021 - PVS Chemicals
recently announced that it had effectively started up a new MECS converter
and steaming equipment licensed by DuPont Clean Technologies at the
company's sulfuric acid plant in Gent, Belgium. This new converter has a
four-pass system, increasing plant's capacity to around 100 kilotons of
sulfuric acid per year and replacing two parallel converter trains. October 26, 2021 - As part of a multi-phased revamp project, the chemical company increases acid plant capacity and optimizes heat integration to ensure reliable & sustainable e-grade acid production for the semi-conductor industry. PVS Chemicals Belgium N.V. (PVS) has successfully started up a new MECS® converter and steaming equipment, licensed by DuPont Clean Technologies (DuPont) at its sulfuric acid plant in Gent, Belgium. The new 4-pass converter which offers a plant capacity increase to approximately 300 mtpd sulfuric acid replaces two parallel converter trains. The converter upgrade along with new steaming equipment will allow PVS to double the plant's saturated steam output. PVS will not only be able to supply steam generated from the new boilers to an industrial neighbor but will also prevent approximately 11,700 tons of CO2 from entering the atmosphere every year – roughly equivalent to planting 195,000 trees annually. The PVS sulfuric acid plant in Gent is one of the few sites globally to produce ultra-high purity sulfuric acid, a critical ingredient for the semiconductor chip industry. David Nicholson, President and CEO of PVS Chemicals Inc. says, "This project and the teamwork, perseverance and hard work shown by all project members, including MECS® field services who worked alongside us through successes and difficulties to deliver the plant, ensure PVS Belgium has a bright future. This project builds on the 126 years of history at this plant and gives it a new heart, so it is ready to run for decades to come." Eli Ben-Shoshan, says, "Sulfuric acid plants are key sources of carbon-free energy. By capturing that energy, the industry can contribute to decarbonizing thermal energy production. We are delighted to be able to assist PVS Chemicals in that aim and to help the plant optimize energy recovery while ensuring reliable, high quality sulfuric acid production so the plant can consistently meet production capacity targets." PVS anticipates that this project will pay for itself within just a few years through the achieved capacity increase and long-term steam supply contract. PVS kicked off its multi-phased plant revamp project in 2018 with a process and engineering assessment by DuPont who was subsequently commissioned with the license and engineering design of the MECS® converter, catalyst and steaming equipment. The design included additional steaming equipment to maximize energy recovery and new generation MECS® GEAR® catalyst was selected to optimize CAPEX. Erection of the equipment, which started in early 2020, was hampered by the COVID-19 pandemic, but DuPont and PVS Belgium safely and successfully completed the erection and tie-in of the new equipment in partnership during a three-week turnaround. DuPont furthermore provided support during commissioning, training, start-up and performance tests.
