LyondellBasell began a planned maintenance outage over the weekend at the OP-2 steam cracker in its Channelview, Texas, complex, sources said Tuesday.
Maintenance on the 930,000 mt/year steam cracker is expected to last 40-60 days, sources said.
A company representative could not be reached for comment Tuesday.
Plans for the maintenance were announced in the company's fourth-quarter 2017 earnings call in early February.
"We have planned maintenance on one of our two crackers at Channelview during the first and second quarter that is estimated to have a $100 million impact on results, with approximately 50% of that occurring during the first quarter," CEO Bob Patel said February 2 during the earnings call.
