MOSCOW (MRC) -- Regional staff continue to provide 24-hour handheld air monitoring around the incident site of TPC Group in Port Neches along with TCEQ contractors, reported TCEQ.
As of Dec. 2, at 10:00 a.m. there have been readings of various compounds including 1,3 Butadiene and Total Volatile Organic Compounds that did not reach levels of immediate health concern. All handheld air monitoring data will continue to be provided to local officials through Unified Command, as well as posted on TCEQ webpage.
EPA is continuing to support TCEQ and local emergency response personnel by conducting flyover monitoring with their ASPECT fixed-winged aircraft. All data continues to be posted on EPA’s emergency response webpage.
Currently all water runoff resulting from firefighting is now being contained onsite and treated prior to discharge. TCEQ has begun to evaluate nearby water bodies for impacts.
As MRC informed earlier, two major explosions and fire hit the TPC Group's Port Neches butadiene and raffinate petrochemical plant east of Houston, Texas, last Wednesday, injuring three workers. The site produces 20% of US butadiene, a raw material used in the production of synthetic rubbers and resins. The outage of the plant is expected to have a "limited impact other than a spike in butadiene prices and more propane feedstock and less ethane on the US Gulf Coast," said Rob Stier, senior lead of global petrochemicals at S&P Global Platts Analytics.
The first explosion occurred at 1 am CST (0700 GMT), and a second occurred about 12 hours later on Wednesday afternoon, according to officials from Jefferson County, which called for evacuations in multiple cities in the area.
Located adjacent to the Sabine Neches River, which is part of the Sabine Neches Waterway, TPC's Port Neches plant can produce more than 900 million lb (426,000 mt) of butadiene and raffinate a year, according to the company's website. The source familiar with company operations said the site has two butadiene lines with capacities of 166,000 mt/year and 260,000 mt/year. The MTBE unit at this site produces up to 400,000 mt/year.
Butadiene is one of the feedstocks for the production of acrylonitrile-butadiene-styrene (ABS).
According to ICIS-MRC Price report, in Asia, the falling prices of feedstocks for ABS production have been pushing prices of material down in the Russian market. LG Chem's import prices for November quantities were as follows for Russian buyers: natural ABS - at USD1,400-1,420/tonne FOB Korea, black ABS - at USD1,610-1,630/tonne FOB Korea, white ABS - at USD1,640-1,660/tonne FOB Korea. December prices may drop by another USD30-50/tonn.
Natural grades of Korean ABS went down to Rb138,000-143,000/tonne CPT Moscow, including VAT, in the domestic market in mid-November, whereas black ABS was offered at Rb156,000-160,000/tonne and white ABS - at Rb158,000-163,000/tonne CPT Moscow , including VAT.
Headquartered in Houston, TPC was acquired in 2012 by private equity groups First Reserve and SK Capital.
