Abstract
Abstract Fossil fuels such as coal or oil are gasified by treatment under superatmospheric pressures with oxygen containing gasifying agents to produce a primary gas containing carbon monoxide and hydrogen. The primary gas is desulfurized and converted in increasing portion into methanol which is stored as the load on the power plant increases. An increasing proportion of the stored methanol is used in addition to desulfurized primary gas in the power plant as the load on the power plant increases.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
78 words
Power plant process which comprises gasifying fossil fuels by treatment under superatmospheric pressure with oxygen-containing gasifying agents to produce a primary gas which contains carbon monoxide and hydrogen, desulfurizing said primary gas, converting an increasing proportion of desulfurized primary gas into methanol for storage as the load on the power plant decreases, and utilizing an increasing proportion of stored methanol in addition to desulfurized primary gas in the power plant as the load on the power plant increases.
Claim 2
Dependent Claim
78 words
Power plant process which comprises gasifying fossil fuels by treatment under superatmospheric pressure with oxygen-containing gasifying agents to produce a primary gas which contains carbon monoxide and hydrogen, desulfurizing said primary gas, converting an increasing proportion of desulfurized primary gas into methanol for storage as the load on the power plant decreases, and utilizing an increasing proportion of stored methanol in addition to desulfurized primary gas in the power plant as the load on the power plant increases.
Claim 3
Dependent Claim
35 words
Process of claim 1 wherein the production of primary gas is continued when the power plant is at a standstill and the primary gas produced during this time is used to produce methanol for storage.
Claim 4
Dependent Claim
17 words
Process of claim 1 wherein methanol produced in the method is used to scrub the primary gas.
Claim 5
Dependent Claim
30 words
Process of claim 3, wherein the methanol used to scrub the primary gas is treated to remove at least part of its impurities and is then used as a fuel.
