General Hubei Xingfa Chemicals Group Co., Ltd. (hereinafter referred to as “XINGFA”) is a public company whose main businesses are developing, producing and marketing a series of phosphoric products and fine chemicals. Established in 1994, XINGFA is located in Xingshan County, Hubei Province, where is known as the birthplace of the famous Han Ming Princess Wang Zhaojun-one of the four ancient beauties in China. XINGFA went public on the Shanghai Stock Exchange (SSE) in 1999, under Stock Code: 600141. The total assets of XINGFA reached up to 25.659 billion RMB, owing 45 whole owned and holding subsidiaries, with stuff of 10,541. Now it ranks 451th among the Top 500 Enterprises of China. Through 20 years of development, XINGFA is now regarded as one of the largest manufacturers of fine phosphoric products in China.

News May 17, 2017 - Yidu Xingfa Chemical Co. Ltd (Xingfa) has awarded DuPont Clean Technologies contracts for the engineering and technology license for a 3600 tpd MECS® MAX3™ sulfuric acid plant. This project will make the Xingfa sulfuric acid plant one of the largest in China.  Xingfa is expanding its existing site, located in the Hubei province near Yichang city, with the aim of roughly doubling the phosphate fertilizer capacity.  The new MECS® MAX3™ sulfuric acid plant will process 1.2 million tpy of sulfuric acid, as well as support the production of an additional 400,000 tpy of phosphoric acid, 400,000 tpy DAP and 35,000 tpy of potassium phosphate monobasic.  The new MECS® MAX3™ sulfuric acid plant will enable the Xingfa site to meet or exceed the Chinese Ministry of Environmental Protection’s strict emission requirements, which govern the location in the sensitive Yangtze river basin area.“DuPont Clean Technologies is very pleased to be providing its proprietary MECS® MAX3™ technology for Xingfa’s expansion project to enable the company to become one of the most efficient fertilizer producers in China. This MAX3™ sulfuric acid plant is not only a significant step for both DuPont and Xingfa, but also for the sulfuric acid industry,” said Eli Ben-Shoshan, president of DuPont Clean Technologies, “Never before has sulfuric acid technology delivered more value to the end user. MAX3™ not only offers sulfuric acid plants savings in water usage, time and money, but it also allows them to recover more energy while achieving best-in-class emission levels.”The MAX3™ sulfuric acid plant for Xingfa’s expansion project will have both high pressure and intermediate pressure steam generation that will be used to produce electricity and provide heat to the plant. The MAX3™ sulfuric acid plant combines a suite of technologies, including two recent technology breakthroughs – SolvR® and SteaMax™ heat recovery – in a revolutionary simplified sulfuric acid flow scheme.The Xingfa configuration will produce more than 1.5 t of high pressure steam per tonne of acid, which is an increase of more than 25% over conventional acid plant technologies. SolvR® is the second-generation regenerative technology which demonstrated best in class SO2 emission abatement at the first commercial installation.  MECS® MAX3™ technology is on the leading edge and further advances DuPont Clean Technologies’ commitment to delivering value to producers of sulfuric acid. This is the first time a sulfuric acid technology has been able to deliver this level of heat recovery, emission performance and favourable capital expense. Furthermore, MECS® MAX3™ sulfuric acid plants are designed for a high on-stream time to avoid disrupting the downstream phosphoric acid production while also providing best in class SO2 emission abatement in compliance with local and country environmental requirements.
