Cenovus Lima Refinery Reports FCCU Flare Event Miguel E. Andujar DTN Refined Fuels Market Reporter DAVENPORT, FL (DTN) -- Cenovus Energy reported Wednesday (5/14) a two-day flaring event at the fluid catalytic cracking unit (FCCU) of its 183,000 bpd Lima Refinery in Lima, Ohio, according to the Ohio Environmental Protection Agency. The event began Wednesday (5/13) evening and ended Friday (5/15), the Ohio EPA said in a statement to DTN. According to information provided by the agency, an issue involving the refinery's FCCU caused flaring from the air pollution control system. The refinery initially reported a federally reportable sulfur dioxide release and later notified regulators that the same event also resulted in a federally reportable release of hydrogen sulfide. Ohio EPA said the refinery is required to submit a more detailed written incident summary in its quarterly report. No additional operational details or mitigation measures were immediately available. The Lima refinery primarily produces gasoline, diesel, and jet fuel. DTN reached out to Cenovus for additional details but did not receive an immediate response. (c) Copyright 2026 DTN, LLC.
