Wanhua Chemical to build isocyanates plant in Louisiana

The project is a push into North America for the Chinese polyurethanes maker

Wanhua’s MDI plant in Ningbo, China, is the world’s largest.

China’s Wanhua Chemical plans to build a $1.1 billion methylene diphenyl diisocyanate (MDI) plant in Louisiana.

Wanhua is the world’s largest producer of the polyurethane raw material, which is also made by U.S. and European firms such as BASF, Covestro, Dow Chemical, and Huntsman Corp. According to the consulting firm IHS Markit, Wanhau’s 1.8 million metric tons of annual MDI capacity represents about 24% of the world’s total.

MDI is reacted with polyols to make the polyurethanes used in rigid insulation, adhesives, and other applications.

The Chinese company hasn’t released details about the project, including the size of the plant or the start-up date. It expects to wrap up site selection later this year. It will foot about $950 million of the bill itself. An unnamed partner will invest about $170 million.

Wanhua operates two MDI plants in its home country. In 2011, it branched out overseas with the $1.7 billion purchase of the Hungarian polyurethanes maker BorsodChem. Its sales in 2015 were about $3 billion.

Last year, Wanhua CEO Zengtai Liao told C&EN that the firm was considering building a plant on the U.S. Gulf Coast.

A company that prides itself on safe and efficient operations, Wanhua suffered an explosion at its Yantai, China, plant last year that killed four. The plant was undergoing maintenance at the time.

Louisiana state officials have been discussing the project with Wanhua since 2013. The company chose Louisiana over potential locations in Texas in part because of incentives including a $4.3 million grant to help offset site infrastructure costs.

At the IHS Markit World Petrochemical Conference in Houston last month, IHS Markit senior analyst James Elliott noted that more MDI capacity would be needed over the next five years to keep up with demand, which is growing at around 4% per year globally.

The situation is particularly acute in North America. “From 2011 to 2016, we have seen a fallow period of MDI additions,” Elliot said. On the horizon for the region are incremental expansions of existing BASF and Huntsman facilities. In addition, Huntsman has been studying building a 400,000-metric-ton plant at its Geismar, La., complex since 2014.

Will they be loading the MDI? If so, into what? Rail cars, trucks...

This is another expected move from Wanhua , who want to become the world number one poly-isocyanates producer. And not just as to MDI / Polymeric MDI, but also as to TDI and aliphatic poly-isocyanates , like HDI , IPDI , etc. They are number one already !!!
But they want more,more.
Wanhua has to show however that they do master the gas-phase phosgenation technology , as this is the future for the bulk of the poly-isocanates, except for MDI.
It would involve the production of TDI , HDI , IPDI , and some others.
The latest built unit for TDI by Wanhua is still based on a liquid solution process.
Like for Basf in Germany , their new 300'000 MT TDI plant is still not properly running , a real catastrophe for Basf , but a windfall profit for the others, due to extreme high prices.

Does Aniline continue to be a major raw material?
