A novel method of combining the CTL fuel plant and IGCC electrical plant by sharing the systems of coal intake, coal preparation, gas separation, and water units is described herein. This configuration allows for the combined facility to offer advantages in efficiencies of production, operational flexibility, scalability, and reliability by a multi-path integration of the processing units.

Integration of an integrated gasification combined cycle power plant and coal to liquid facility

A plant for producing Fischer-Tropsch liquids and electrical power with greatly reduced emissions of carbon dioxide to the atmosphere is made up of a syngas generator unit, an air separation unit, a Fischer-Tropsch unit, a COremoval unit, and a combined cycle electricity generation unit. Each of Fischer-Tropsch liquids, carbon dioxide, and electrical power can be recoverable under proper economic conditions. Electrical power is recoverable by the use of a gas turbine fueled by predominantly hydrogen and a steam turbine powered by steam generated by cooling exhaust gases from the gas turbine. Sequestration of COand fueling the gas turbine with hydrogen reduces the amount of greenhouse gases emitted to the atmosphere.

Integrated Fischer-Tropsch and power production plant with low CO2 emissions

A plant for manufacturing urea from carbonaceous materials, oxygen from an air separation unit and water, preferably steam, is made up of a syngas generator unit, an air separation unit, Fischer-Tropsch unit, a CO removal unit, a hydrogen removal unit, a methanator unit, an ammonia converter unit and a urea synthesizer unit. Each of Fischer-Tropsch liquids, ammonia, hydrogen and urea can be recoverable under proper economic conditions. Electrical power is recoverable by the addition of at least one of a steam turbine and a gas turbine which is/are coupled to an electrical generator.
