WebHigh-temperature coking is a semicontinuous process designed to convert asphaltic residua to gas oil and coke as the primary products. In the process the feedstock is transported to the heater (370°C, 700°F, 30 psi) and finally to the coking unit, where temperatures may be as high as 980°C–1095°C (1800°F–2000°F). WebThe coking time is determined by the coal mixture, moisture content, rate of underfiring, and the desired properties of the coke. When demand for coke is low, coking times can be extended to 24 hours for blast furnace coke and to 48 hours for foundry coke. Coking temperatures generally range from 900° to 1100°C (1650° to

WebThus Flexicoking is an integrated coking and gasification process for upgrading heavy feedstocks. This process converts these feeds to a 99% yield of fuel gas, naphtha, middle distillates, heavy gas oil, and a low-sulfur coke gas. The remaining 1% is petroleum coke containing metals and other ash components present in the feed. port of centralia staff

WebJan 7, 2024 · A flowchart is a diagram that illustrates the steps, sequences, and decisions of a process or workflow. While there are many different types of flowcharts, a basic flowchart is the simplest form of a process map. It’s a powerful tool that can be used in multiple fields for planning, visualizing, documenting, and improving processes. WebA delayed coker is a type of coker whose process consists of heating a residual oil feed to its thermal cracking temperature in a furnace with multiple parallel passes. This cracks the heavy, long chain hydrocarbon molecules of the residual oil into coker gas oil and petroleum coke.

WebContinuous Coking. Continuous (contact or fluid) coking is a moving-bed process that operates at temperatures higher than delayed coking. In continuous coking, thermal cracking occurs by using heat transferred from hot, recycled coke particles to feedstock in a radial mixer, called a reactor, at a pressure of 50 psi. WebThe delayed coker is one of the key processes in the refinery where heavier crudes are being processed. Optimizing this process is becoming increasingly important, and good measurement is a key factor to be able to effectively evaluate coker operations.
