HOUSTON (ICIS)--Indorama Ventures's ethylene oxide (EO)/ethylene glycol (EG) unit at its Clear Lake, Texas plant was shut down on April 6 because of mechanical issues, according to a filing with the Texas Commission on Environmental Quality (TCEQ) on Tuesday.
The unit went down for 4.5 hours as another site partner where Indorama sends its carbon dioxide (CO2) tripped, forcing the shutdown, an Indorama official told ICIS.
The unit was back at full rates by the end of Sunday, the official said.
The shutdown resulted in a potential ethylene vent to the atmosphere, according to TCEQ.
The Clear Lake plant has a capacity of 960m lb/year (435,000 tonnes/year) of crude EO and 790m lb/year (358,000 tonnes/year) of monoethylene glycol (MEG).
EO is predominantly used to make EG. The second-largest outlet is in surface active agents, including non-ionic alkylphenol ethoxylates and detergent alcohol ethoxylates.
EO producers in the US include BASF, Dow Chemical, Eastman, Formosa Plastics, Huntsman, Indorama Ventures, LyondellBasell and Shell Chemical.
