Chevron Phillips Chemical Co. said it plans to flare gases from an ethylene unit at its Port Arthur facility in Texas, according to a filing with state regulators.
The flaring, or release of gases into the air, will start today and last until Feb. 1, and is related to “planned maintenance activity” on a so-called acetylene converter, according to the filing with the Texas Commission on Environmental Quality.
Chevron Phillips Chemical is a joint venture between Chevron Corp. and ConocoPhillips. Flaring is a safety measure that prevents excessive pressure from building up in processing units that are being shut down or started up. Ethylene is used in plastics.
