According to Bloomberg, Dow Chemical Company had a production interruption at its light hydrocarbon plant in Freeport, Texas. Dow’s Light Hydrocarbon 7 plant had an upset in the internal hydrogen supply to the acetylene reactors that caused flaring of “offspec” ethylene, according to two fillings with the Texas Commission on Environmental Quality. Dow’s Freeport chemical complex is about 65 miles south of Houston. The Midland, Michigan-based company’s Texas operation is Dow’s largest integrated site. The Texas operations manufacture 44 percent of Dow products sold in the U.S. and more than 21 percent of Dow products sold globally.
