WEST BOUNTIFUL – Holly Refinery is investigating the cause of a small fire Monday that started in a unit that removes sulphur from heavy hydrocarbon product to be used as gasoline.
The fire started about 2:30 p.m. as the result of a leak in a a flange on a pipe, according to Mike Astin, environmental manager for the plant.
“Operators immediately recognized the problem and got water on it right away,” Astin said, explaining the water wasn’t meant to put out the blaze, but to cool the system down as operators shut the unit down.
They also sounded the evaluation alarm for that unit, so no one was hurt, Astin said.
Police closed 800 West for about an hour.
Refinery employees tested the air surrounding the plant and picked up zero emissions from the fire, Astin said.
The fire was allowed to burn itself out. Crews worked to cool the unit until about 6:30 p.m.
