Coker. Also known as: delayed coker, DCU. In a refinery, the coker is the most extreme of the bottoms upgrading process units. A coker takes the lowest value bottoms material (vacuum resid) and cracks it to the point that all of the resid is eliminated, yielding only lighter fractions and solid carbon .
Aug 08, 2019· A coker unit is a thermal cracking process in the oil refinery industry used to recover valuable elements, the most important of which being petroleum coke from main refinery process residues. The coking process involves feeding heated residual oil or pitch into the bottom of a large, upright vessel known as a coke drum, where the thermal cracking takes place.

Unlike other petroleum refinery operations, the DCU is a semi-batch operation, involving both batch and continuous stages. The batch stage of the operation (drum switching and coke cutting) presents unique hazards and is responsible for most of the serious accidents attributed to DCUs. ... "Delayed Coker Unit," yields many sources of ...
Apr 17, 2019· The Co-op Refinery Complex (CRC) aims to be a recognized leader in safety, reliability and sustainability within the petroleum-refining industry. From eight enterprising farmers who believed they could produce and distribute their own gas in 1935, the CRC has grown to become one of Canada's largest integrated refining and upgrading complexes.

An efficient Delayed Coker operation enhances a refinery's …
Coker Units or Cokers, are pieces of oil refinery processing equipment used to recover specific elements from process residues, tar pitch, and residual oils.. The coking process involves what is known as cracking; where long chains of hydrocarbons are broken down into shorter chains by heating them to their thermal cracking temperature in a furnace.
The Martinez refinery is located on an 860-acre site in the City of Martinez, 30 miles northeast of San Francisco, California. The refinery is a high-conversion 157,000 barrel per day, dual-coking facility with a Nelson Complexity Index of 16.1, making it one of the most complex refineries in the United States.
Apr 11, 2019· On January 1st, 2020, the global shipping industry will undergo a radical change, with all ships having to reduce the sulfur content within marine fuels from 3.5% to 0.5%, as mandated by the International Maritime Organization (IMO). As with all radical changes, winners and losers await, meaning there is significant opportunity everywhere. In this paper, […]
Nov 30, 2015· The Port Arthur Refinery is the largest in the United States. Motiva is a 50-50 joint venture between Royal Dutch Shell Plc and Saudi Aramco. A 54,000 bpd coker at the refinery remained in operation while DCU-2 was malfunctioning. A coker increases the amount of refinable material obtained from a barrel of oil.
The Refining Community offers excellent technical training courses for Delayed Coking (DCU), Fluid Catalytic Cracking (FCCU), Coke Drum Integrity, and other petrochemical topics. Courses are offered before RefComm ® conferences around the world, individually at regional locations and customized on-site for refinery, plant and vendor locations.
In a Refinery the Delayed Coker Unit Process is a type of Coking Process where residual oil from vacuum distillation column is converted to low molecular weight hydrocarbon gases, naphtha, etc. In the Delayed Coking Process, the residual oil is heated to its cracking temperature in a furnace.The heating in the Delayed Coker Unit Operation, cracks the long chain heavy carbon and hydrogen ...
BP Coker Whiting Refinery. Project Overview.

This upgrade brought the capacity to produce an additional 1.7 ...
Petroleum refining - Petroleum refining - Visbreaking, thermal cracking, and coking: Since World War II the demand for light products (e.g., gasoline, jet, and diesel fuels) has grown, while the requirement for heavy industrial fuel oils has declined. Furthermore, many of the new sources of crude petroleum (California, Alaska, Venezuela, and Mexico) have yielded heavier crude oils with higher ...
Coking is the most severe thermal process used in the refinery to treat the very bottom-of-the-barrel of crude oil, i.e., vacuum residue. Because of the high severity of thermal cracking during coking, the residue feed is completely converted to gas, light and medium …
The launch of ExxonMobil's delayed coker at the 320,000 b/d Antwerp refinery in October 2018 has taken an estimated 200,000 mt/month of fuel oil out of the market. The DCU at ExxonMobil Antwerp is 50 kB/SD fresh feed (343 metric tons/hr) to a Foster-Wheeler designed 4-drum coker.
Industrial: Refining: Coker Units The atmospheric and vacuum distillation columns bottoms, or residuum, can be further processed into more desirable products. This is accomplished by running the resid through a Coker Unit. Cokers are one of two types, either fluid cokers or delayed cokers.
All coker products and spalling streams go to the operating coke drum as before the decoking started. OLS improves coker profitability of the refinery by improving the on-stream factor of the unit and refinery significantly by allowing the continued operation of the coker during decoking.
