Systems and methods for reducing atmospheric emission of hydrocarbon vapors by flashing off hydrocarbon vapors in an overflow drum where the pressure is ultimately reduced to 0 psig and then flashing off any remaining hydrocarbon vapors in an overflow tank wherein the pressure in the overflow tank is reduced to 0 psig by an overflow ejector.

A process and apparatus for improving the production of coke having a high volatile combustible material content are disclosed. The process may include, for example: heating a coker feedstock to a coking temperature to produce a heated coker feedstock; contacting the heated coker feedstock with a quench medium to reduce a temperature of the heated coker feedstock and produce a quenched feedstock; feeding the quenched feedstock to a coking drum; subjecting the quenched feedstock to thermal cracking in the coking drum to (a) crack a portion of the quenched feedstock to produce a cracked vapor product, and (b) produce a coke product having a volatile combustible material (VCM) concentration in the range from about 13% to about 50% by weight, as measured by ASTM D3175.

Systems and methods involving hydrocatalytic reactions that thermal energy obtained from combustion of coke generated by coking of at least a portion of the hydrocatalytic reaction product. Hydrocatalytic reactions can require substantial amounts of thermal energy. The present disclosure provides systems and methods that can allow for reducing the carbon footprint of the fuels formed from the hydrocatalytic reaction because at least a portion of the thermal energy used in the hydrocatalytic reaction has low carbon footprint. A fuel with low carbon footprint can qualify for certain governmental status that provides certain benefits.

An integrated process is provided for producing deasphalted oil, high quality petroleum green coke and liquid coker products. An enhanced solvent deasphalting process is used to treat the feedstock to reduce the level of asphaltenes, N, S and metal contaminants and produce a deasphalted oil with reduced contaminants. A coking process is integrated to produce liquid and gas coking unit products, and petroleum green coke.

The invention relates to processes for producing anode grade coke from whole crude oil. The invention is accomplished by first deasphalting a feedstock, followed by processing resulting DAO and asphalt fractions. The DAO fraction is hydrotreated or hydrocracked, resulting in removal of sulfur and hydrocarbons, which boil at temperatures over 370 C., and gasifying the asphalt portion in one embodiment. This embodiment includes subjecting hydrotreated and/or unconverted DAO fractions to delayed coking. In an alternate embodiment, rather than gasifying the asphalt portion, it is subjected to delayed coking in a separate reaction chamber. Any coke produced via delayed coking can be gasified.

Processes and systems are provided for converting a carbonaceous feedstock into a reaction gas and a syngas, involving a step of pyrolysing and methanating the feedstock in a pyrolysis chamber to produce the reaction gas and a step of gasifying unconverted feedstock in the presence of a reactant to produce a syngas.
