Nov. 22 (Bloomberg) -- Husky Energy Inc. completed maintenance on a coker and fluid catalytic cracker at its Lima, Ohio, refinery, and has begun the restart process, said Graham White, a company spokesman.
“Start-up could take a week or more, depending on any issues arising,” White said today in an e-mail. The maintenance was a partial turnaround, affecting about 30 percent of the plant, he said.
“We still operated, but at slightly reduced rates and we continue to operate at those rates, so overall impact on production has been minor,” according to White.
The refinery’s production units include a fluid catalytic cracker, a hydrocracker, a delayed coker and a catalytic reformer. Cat crackers process vacuum gasoil into gasoline or lighter products while hydrocrackers convert heavy hydrocarbons into fuels such as diesel.
Last week, Husky informed the Ohio Environmental Protection Agency that it was in the process of bringing some units back online, said agency spokeswoman Dina Pierce.
A new Nebraska steam boiler, which replaced a carbon monoxide boiler, is operating and the old boiler was permanently shut down, she said.
A Claus No. 1 sulfur recovery unit and control equipment comprising a tail gas heater with an incinerator, were in start-up mode as of Nov. 15, although the Claus No. 2 sulfur recovery unit was still down for maintenance, the refinery said in a report to the agency.
Start-up notification for all units is expected “around the end of November, first of December,” Pierce said.
The refinery makes 25 percent of the gasoline used in Ohio, along with 30,000 barrels a day of diesel and 25,000 of jet fuel, plus residual fuels and petrochemical feedstocks, according to the company’s website. About 80 percent of the crude processed at the refinery is domestic, with additional supplies from the North Sea and West Africa, according to the Canadian company.
The Lima plant has a capacity of 155,000 barrels a day, according to data compiled by Bloomberg. The refinery accounts for about 4.2 percent of the refining capacity in the Midwest, or PADD 2, region of the U.S.
