A Highly Efficient Integrated Power and Technological Natural Gas Utilization System for Producing Electricity, Heat, and Synthetic Liquid Fuel with Partially Sequestering Carbon Dioxide Emissions into the Atmosphere

Abstract

This article presents a description and comparative analysis of an integrated natural gas utilization technology for concurrently producing electricity and synthetic liquid engine fuel and partially sequestering carbon dioxide. In the daytime, the installation produces electricity, heat, and methanol. In the night-time hours of minimum load, CO2 is partially captured from flue gases and is converted in a plasmatron to obtain H2 + CO by adding natural gas and steam. The produced synthesis gas is forwarded to a catalytic synthesis reactor for boosting the operation of the methanol producing installation. In comparison with state-of-the-art installations for separate production of electricity, heat, and methanol, the proposed installation makes it possible to save about 20% of natural gas and decrease the amount of CO2 emissions into the atmosphere by as much as 30%.
