Chevron Phillips Chemical has begun a restart of the last remaining offline cracker at the Sweeny site after shutting it as Hurricane Harvey pummeled the Texas coast in late August, a filing with state regulators showed Monday.
The 250,000 mt/year Ethylene Unit 22 began restart operations on Monday, with emissions associated with the startup expected to run through November 24, the filing with Texas Commission on Environmental Quality showed.
The Sweeny site includes three steam crackers: ethylene units 22, 24 and 33.
Ethylene unit 24, with an production capacity of 668,000 mt/year, was restarted September 10, according to a separate filing with TCEQ, and the 1.025 million mt/year Ethylene Unit 33 was heard to be restarting on September 17, a source said.
