Overview

Underground coal gasification is a process which enables

Underground Coal Gasification (UCG) is a gasification process applied to non-mined coal seams, using injection and production wells drilled from the surface, which enables the coal to be converted in situ into product gas. The process has produced commercial quantities of gas for both chemical processes and power generation.

Underground Coal Gasification. With underground coal gasification (UCG), the actual process takes place underground, generally below 1,200 feet. The underground setting provides both the feedstock source as well as pressures comparable to that in an above-ground gasifier. With most UCG facilities, two wells are drilled on either side of an

Underground Coal Gasification and Combustion | ScienceDirect

Underground coal gasification research and development took place in the United States from 1948 to 2015, including the intense and productive period from the mid-1970s to the late 1980s. The marquis activities were extensively-monitored field tests. A conceptual understanding of how UCG works was developed along with mathematical models of the

Underground Coal Gasification | netl.doe.gov

Underground Coal Gasification (UCG) takes advantage of the same chemical reactions of coal to produce product gases, as those occurring in conventional gasifier reactors. The main difference is that in UCG the underground coal seam itself becomes the reactor, so that the gasification of the coal takes place underground instead of in a manufactured gasification vessel at the surface.1 Obviously

South Africa: The future of underground coal gasification

Sep 25, 2018· In broad terms UCG is a technology where coal is ignited underground with a controlled flow of oxidant gas, (such as air, enriched air etc.) and water. It converts the coal into synthetic gas, of which the gas is directly used as fuel, co-fired with other fuels such as natural gas, or coal and can power gas turbines for electricity generation.

A. Taskaev, in Underground Coal Gasification and Combustion, 2018. Abstract. Underground coal gasification technology, conceived in 1868, has not attained a fully commercial status after almost 150 years of its development. It is important to spell out specific criteria that must be met before UCG may be considered for a large commercial

Economic overview of a two-agent process for underground

Introduction. Underground Coal Gasification (UCG) is a mining method that utilizes gasification to produce gas from in situ coal (underground in the coal seam) by injecting combinations of air, oxygen, steam and carbon dioxide (CO 2) as gasification agent into coal seams and extracting the product gas to the surface via boreholes.UCG is a high-extraction mining method operating at least two

Underground Coal Gasification Flexis GRC Engineering

Underground Coal Gasification (UCG) is the process by which coal is converted in-situ into a gas product that can be combusted for power generation or used as a chemical feedstock. UCG exploits coal resources that are either uneconomical to mine with conventional mining methods or are inaccessible due to depth, geology or other mining and
