The Plant for Co-production of Synfuel and Electricity with Reduced CO2 Emissions

摘要

Consideration is given to the prospective technologies for combined production of synthetic fuel (SF) and electricity. The mathematical models of plant for co-production of synfuel and electricity (PCSE) intended for combined production of electricity and synthesis of methanol and dimethyl ether or membrane-based hydrogen production from coal were developed. They were used in the optimization studies on the installations.As a result of the studies, the design characteristics for the plant elements, the relationships between the SF and electricity productions,etc.were determined. These data were used to identify the ranges of SF price for various prices of fuel,electricity and equipment,and estimate the profitability of SF production.Special attention is paid to modeling of CO2 removal system as part of PCSE and studies on PCSE optimization. The account is taken of additional capital investments and power consumption in the systems.
