Abstract:
1. A delayed coking system comprising: a heater section adapted to heat a combined delayed coking system feed and recycle to temperatures exceeding 900 degrees Fahrenheit; a coke drum section in association with said heater section, said coke drum section adapted to delay coking of heavy hydrocarbons and crack heavy hydrocarbons to light hydrocarbon vapors; a fractionation section in association with said coke drum section, said fractionation system adapted to separate said vapors into useful products including a coker process stream; and a chemical reactor system adapted to control temperature, pressure, and flow rate in a manner adapted to facilitate further chemical reactions of the coker process stream and return a product stream to said fractionation section; wherein said delayed coking system is adapted to facilitate additional chemical reactions that cause a favorable modification of a quantity, a yield characteristic, a quality, or a property of a resulting product.
