Yidu Xingfa Chemical awards DuPont contract for sulfuric acid plant
WILMINGTON, Del. — Yidu Xingfa Chemical Co. Ltd. has awarded DuPont Clean Technologies contracts for the engineering and technology license for a 3,600 Mtpd 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 MMtpy 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.
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 Xingfa configuration will produce more than 1.5 t of high pressure steam per ton 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.
