Abstract
An apparatus and method of producing methanol includes reacting a heated hydrocarbon-containing gas and an oxygen-containing gas in a reactor; to provide a product stream comprising methanol; and transferring heat from the product stream to the hydrocarbon-containing gas to heat the hydrocarbon containing gas. After removing methanol and CO2 from the product stream, unprocessed hydrocarbons are mixed with the hydrocarbon containing gas fro reprocessing through the reactor.
Claims29
A method of producing methanol, comprising:
- supplying a first stream of heated hydrocarbon-containing gas into a reactor;
- supplying into the reactor an oxygen-containing gas;
- carrying out in the reactor oxidation of the first stream of heated hydrocarbon-containing gas by oxygen of the oxygen-containing gas to provide a product stream comprising methanol and formaldehyde;
- and transferring heat from the product stream to the first stream of heated hydrocarbon-containing gas after the reaction;
- removing the methanol from the product stream;
- and
- removing CO2 from the product stream to form a reduced product stream comprising hydrocarbons by contacting with an absorbent, wherein the first stream comprises at least a portion of the reduced product stream.
