Sludges of high oil content are developed and then injected into a delayed coking unit during the coking phase so that they are converted to coke and liquid coking products.
A process is described of delayed coking optimised for greater yield of diesel oil from coke by means of modifications to the feedstock in a Delayed Coking Unit.
The present invention is a method for detecting an abnormal event for process units of a Delayed Coking Unit.
Fort Hills’ installations include a diluent recovery unit (DRU), a delayed coking unit (DCU) and related infrastructure.
The first contract, worth approximately Canadian dollar 870 million (€545 million), is for a diluent recovery unit (DRU) and a delayed coking unit (DCU).
The present invention is a method to remove coke from a coker drum.
(a) a carbonaceous solid produced from an oil refinery coke unit or an oil or bitumen upgrader coker unit;

(a) a carbonaceous solid produced from an oil refinery coke unit or an oil or bitumen upgrader coker unit;
Oil refineries use a coker unit to recover valuable elements.
The coke/water mixture is released from the coke drum through one or more drum closure/discharge throttling systems near the bottom of the coker drum.
A second coker producing approximately 100,000 b/d is expected to return to service during the first half of August.
Special antifoam additives may be used to prevent catalyst poisoning from silicone carryover in the coker feedstock.
A second coker producing approximately 100,000 b/d is expected to return to service during the first half of August.
These products are extracted from the refinery residues in a section of the plant known as a coker unit, typically one of the final steps in the refinery process.
An automatic batch sequence computer control system is configured to automatically operate process valves in a delayed coker for a complete coke drum cycle.
A second coker, producing approximately 100,000 bbls/d, is expected to return to service during the first half of August.
When feedstocks are from the delayed coker or the TCC, corrosion from hydrogen sulfide and deposits in the high pressure sections of gas compressors from ammonium compounds is possible.
A second coker, producing approximately 100,000 bbls/d, is expected to return to service during the first half of August.
Syncrude operated at lower rates for much of the quarter due to maintenance on a hydrogen plant and operating issues with a coker unit.
One coker, producing approximately 150,000 barrels per day (bbls/d), is expected to return to service during the second half of July.
Production at Syncrude has returned to normal operating rates following accelerated planned maintenance and the restart of the third and final coker.
Cooling coker feed to a manageable temperature is very doable when you’ve got the right equipment and expertise.
One coker, producing approximately 150,000 b/d is expected to return to service during the second half of July.
The invention includes the steps of impinging fluid from a fluid jet on the inside surface of the coker and then determining the vibration signal of the coker drum.
