Embodiments relate generally to systems and method for processing tars to produce benzene, toluene, and xylene (BTX). A method for processing tars may comprise distilling the tars to separate creosotes and pitch; and processing the pitch via hydropyrolysis, including both hydrogenation and hydrocracking functions, to remove heteroatoms and break down polyaromatics in the pitch and produce monoaromatics, such as BTX. A system for processing tars may comprise one or more of the following: an input stream comprising tars feeding into a column; the column configured to separate the tars into one or more creosote streams and a pitch stream; and a reactor (or a series of reactors, or beds within a single reactor), wherein the pitch stream is fed to the reactor along with a stream of hydrogen, wherein the reactor is configured to break down the pitch to produce BTX.

Processing of gasification tars to high yields of BTX

A method of processing stranded remote gas comprising (a) introducing stranded remote gas and steam to a reforming unit to produce synthesis gas (syngas), wherein the stranded remote gas comprises methane, carbon dioxide, and sulfur-containing compounds, and wherein the syngas is characterized by a molar ratio of hydrogen to carbon monoxide of from about 1.7:1 to about 2.5:1; (b) introducing at least a portion of the syngas to a Fischer-Tropsch (FT) unit to produce an FT syncrude product, FT water, and FT tail gas, wherein the FT syncrude product comprises FT hydrocarbon liquids, wherein the FT syncrude product comprises FT wax in an amount of less than about 5 wt. %, and wherein the FT unit is characterized by an FT reaction temperature of from about 300&#xb0; C. to about 350&#xb0; C.; and (c) blending the FT syncrude product with crude oil for storage and/or transport.

Small scale modular gas to liquids plant for stranded remote gas

A crude oil processing plant that comprises a Fischer-Tropsch reactor is disclosed. The crude oil processing plant comprises a crude oil processing section and a hydrogen production section. The hydrogen production section is coupled to a hydrocracker in the crude oil processing section to deliver a high purity hydrogen stream. The Fischer-Tropsch reactor receives a syngas stream from the hydrogen production section and produces a hydrocarbon stream. When light crude oil is processed, the hydrocracker typically has excess capacities to upgrade the hydrocarbon stream from the Fischer-Tropsch reactor.

Configurations and method of integrating a gas to liquids (GTL) plant in a refinery

Systems and methods for pre-treatment of acid gas are presented in which ammonium is removed from the acid gas in an absorber that is operated at significantly elevated temperature using dilute phosphoric acid. While seemingly incompatible, absorbing ammonia at high heat in the absorber will allow for production of a diammonium phosphate product that is ultra-low in residual sulfurous compounds and prevent crystallization of phosphate salts due to the increased solubility of the salts in the hot diluted solvent.
