UPDATE 2-BP says TX ultraformer starting repairs
* Ultraformer undergoing unplanned overhaul - source
* Refinery has total reforming capacity of 138,000 bpd
(Adds details from source)
NEW YORK, March 19 (Reuters) - BP Plc (BP.L) (BP.N) said that a gasoline-making ultraformer unit at its 455,790 barrel-per-day Texas City, Texas, refinery will halt production during equipment repair starting Friday.
"The Ultraformer (No.) 4 will discontinue production and repair process equipment," BP added in a filing with the Texas Commission on Environmental Quality (TCEQ).
A company spokesperson declined to provide additional details about the work. The filing did not specify the nature of the repairs but noted that associated emissions were seen lasting through April 3.
"That's the expected window for flaring," said a source familiar with refinery operations, noting that the work entails unplanned work on the unit.
"It's a repair not a planned turnaround," the source said.
The capacity of the unit -- one of two ultraformers at the refinery -- was not immediately available but BP publishes that it has a gross reforming capacity of 138,000 bpd at Texas City.
"Unit procedures dictate the use of the fuel gas system when venting and purging any process equipment. When this isn't possible, the gases are routed to flare," added the TCEQ filing.
