A fire that started around midnight Tuesday at CVR Refining’s Coffeyville unit sent four employees to the hospital and prompted a shutdown, the company said.
The fire was reported at CVR’s isomerization unit at 12:30 a.m. CDT Tuesday.
It was reported to be extinguished at 1:18 a.m. CDT.
The isomerization unit is used to produce isobutane and higher-octane gasoline.
The identities of the four injured employees have not been released.
CVR is providing assistance to the injured employees and their families, the company said.
The extent of the injuries wasn’t reported.
CVR is an independent refiner based in Sugar Land, Texas. It owns refining and related logistics assets throughout the Midcontient of the U.S.
The Coffeyville, Kansas Fire Department said the employees were working on a pump when it caught fire and flames engulfed the area.
CVR has not confirmed the cause of the fire or the extent of the damage to the refinery.
All other employees are accounted for, the company said.
The refinery is about 100 miles from the large crude oil trading and storage hub in Cushing, Oklahoma. CVR’s Coffeyville, Kansas and Wynnewood, Oklahoma refineries receive crude from the hub.
Crude traders expect the fire to place pressure on prices.
The price of West Texas Intermediate oil fell to a two-week low Tuesday on concerns that the Coffeyville refinery shutdown will reduce crude demand, Bloomberg said.
CVR owns 1 million barrels of storage at Cushing and leases 3 million barrels of tankage.
The Coffeyville refinery has a production capacity of 115,000 barrels per day and mostly produces gasoline, diesel fuels and propane.
