MOSCOW (MRC) -- Royal Dutch Shell Plc is finishing a planned multi-unit overhaul as it begins restarting the large crude distillation unit (CDU) at its 340,000 barrel-per-day joint-venture Deer Park, Texas, refinery, said sources familiar with plant operations, said Hydrocarbonprocessing.
The 270,000 bpd DU-2 CDU was shut on Sept. 23 at the start of the multi-unit overhaul planned to last for about two months, the sources said.
Shell spokesman Ray Fisher said planned work was still underway at the Deer Park refinery, which is a joint-venture between Shell and Mexico’s national oil company Petroleos Mexicanos.
In addition to DU-2, Shell shut the 92,000 bpd coker, the 67,000 bpd hydrocracker and 40,900 bpd gas oil hydrotreater along with several other units.
The gas oil hydrotreater restarted on Tuesday. The hydrocracker is preparing to restart along with DU-2. The coker will restart along with the CDU or shortly after it, the sources said.
DU-2 is the larger of two CDUs doing the primary breakdown of crude oil into hydrocarbon feedstocks for all other production units at the refinery.
The coker converts residual crude oil from distillation units into feedstocks for motor fuels or petroleum coke, a coal substitute. Hydrocrackers use hydrogen under high pressure and high heat with a catalyst to convert gas oil into motor fuels, primarily hydrogen. Hydrotreaters remove sulfur from motor fuels in compliance with U.S. environmental rules.
As MRC wrote before, in mid-October 2019, Royal Dutch Shell Plc restarted the hydrocracker at its 225,300 barrel-per-day (bpd) Norco, Louisiana, refinery. The 40,000 bpd hydrocracker was shut on Sept. 9 for a planned month-long overhaul. A longer than expected restart of the unit stretched the outage to six weeks, the sources said.
Ethylene and propylene are feedstocks for producing polyethylene (PE) and polyprolypele (PP).
According to MRC's ScanPlast report, Russia's estimated PE consumption totalled 1,589,580 tonnes in the first nine months of 2019, up by 7% year on year. Shipments of all PE grades increased. The estimated PP consumption in the Russian market was 976,790 tonnes in January-September 2019, up by 4% year on year. Shipments of PP block copolymer and homopolymer PP increased.
