In the Delayed Coker unit, Vaccum residue is rapidly heated in heater and thermally cracked in coke drums under certain operating conditions of pressure and temperature. Delayed coker products are Fuel gas, LPG, Naphtha, Light coker gas oil, Heavy coker gas oil and Coke. The products from Delayed coker are sent to …

One of these conversion methods is the delayed coker unit (DCU). The product obtained from this unit is commonly known as petroleum coke which serves as the feed for a number of different applications. Unlike the other processing units in the refining business, delayed coking is a discontinuous batch operation. Full coker drums are opened on a ...

Ensure your coker unit refinery outputs meet your water quality requirements on final products and intermediates. What is Coking? Coking is a unit operation found in more complex refineries to convert tarry residual or 'resid' streams from vacuum and atmospheric distillation into value-added products and intermediates such as LPG, naphtha ...

A coker crane in a petrochemical plant moves hot, fresh coke fuel in the coke pit out of the way of the coke drum so that coke gets cool down. After 24 hours, the crane moves the cooled, de-watered coke to a crusher, hopper, or conveyor. The work is fast and continuous, and downtime completely halts production.
