This petroleum coke can either be fuel grade (high in sulphur and metals) or anode grade (low in sulphur and metals). The raw coke from the coker is often referred to as green coke. [1] In this context, "green" means unprocessed. The further processing of green coke by calcining in a rotary kiln removes residual volatile hydrocarbons from the ...
Stated succinctly, coke is the "carbonization product of high-boiling hydrocarbon fractions obtained in petroleum processing (heavy residues)". [1] Petcoke is also produced in the production of synthetic crude oil (syncrude) from bitumen extracted from Canada's oil sands and from Venezuela's Orinoco oil sands .
The refinery processed approximately 44,500 barrels of crude oil per day. The facility's main operation was to convert heavy crude oil into high quality feedstock for additional processing at the connected Rodeo Facility. Additional finished products produced at the facility were petroleum coke (carbon) and sulfur. [5]
Gas emission. Coke oven interior: detail (1942, USA). The coke oven is the central element of a coking plant. Horizontal ovens, which are the most commonly used (they are suitable for monitoring the various extraction stages), take the form of narrow compartments (approx. 50 cm wide), but several meters high and several meters deep.
JEA Northside Generating Station in Jacksonville, Florida is a major power plant, one of the three power plants owned and operated by JEA, Jacksonville's municipal utilities service. It produces electricity by burning coal and petroleum coke at Units 1 and 2, formerly the largest circulating fluidized-bed combustors
The yield of coke from the delayed coking process ranges from about 18 to 30 percent by weight of the feedstock residual oil, depending on the composition of the feedstock and the operating variables. Many refineries worldwide produce as much as 2,000 to 3,000 tons per day of petroleum coke and some produce even more. [5]
In 2022, non-profit environmental group San Francisco Baykeeper sued Valero and Amports, a shipping operator, alleging that the companies had been dumping petroleum coke (or "petcoke") from Valero's Benicia Refinery into the San Francisco Bay. The lawsuit was settled in October 2024 for $2.38 million, with the companies also agreeing to site ...
The refinery was built in 1906 by the National Refining Company, which was then the second largest oil company in the United States.Built on 75 acres (30 ha), the refinery processed 2,500 barrels per day (400 m 3 /d) of crude oil, compared to today's 108,000-barrel-per-day (17,200 m 3 /d) processing capacity.
