Researchers find cheaper, less energy-intensive way to purify ethylene


Researchers at The University of Texas at Arlington have filed a provisional patent application on a new copper compound that can be used to purify ethylene. The ethylene is used as a raw material in the production of plastics such as polyethylene or PVC, as well as other industrial compounds. Ethylene is produced from crude oil but is usually obtained as a mixture containing ethane. Manufacturing processes using ethylene usually require pure, or 99.9 percent, ethylene feed-stock. “Existing technologies to separate ethylene and ethane use enormous amounts of energy and require high levels of capital investment.

Crude oil and natural gas production has increased in US, despite the decline in number of wells, according to a report by Energy Information Administration. A report stated that how the daily production rates of individual wells contributed to US total crude oil and natural gas production in 2017. The total number of wells producing crude oil and natural gas in the United States fell to 991,000 in 2017, down from a peak of 1,039,000 wells in 2014. This recent decline in the number of wells reflects advances in technology and drilling techniques. Wells classified as nonhorizontal in the report—most of which are vertical wells—have decreased from 940,000 in 2014 to 864,000 in 2017. Read More

Wanhua Chemical Group has decided to develop a new $1.25 billion American chemical manufacturing complex in Convent, Louisiana. The new methylene diphenyl diisocyanate (MDI) plant has a capacity of 400 kilotons per year. This project will generate 1,000 construction jobs at peak activity, and create 1,230 new direct and indirect jobs. The North American polyurethane market has witnessed continuous growth in recent years. Once operating at full capacity, the new facility will greatly enhance Wanhua’s supply capability and stability of MDI in North America, as well as broaden the product portfolio. The Louisiana project represents Wanhua’s commitment to bring manufacturing to the US and to enable the company to better serve the customers. Read More
