Co-production device for producing hydrocarbon through methanol dehydration as well as cold, heat and power

Abstract

The invention relates to a co-production device for producing hydrocarbon through methanol dehydration as well as cold, heat and power, which is characterized in that methanol is used as raw materials to co-produce petroleum, liquefying gas as well as cold, heat and power, and heat, dry gas and water generated by hydrocarbon production through the methanol dehydration are used for a cooling and heating electric device and can lower the production cost of the device; and liquefying gas generated by the raw materials of methanol and the hydrocarbon production through the dehydration can also be used for the cooling and heating electric device so as to enhance the regulating capacity of the cooling and heating electric device. The raw material methanol has rich sources, and crude methanol can be used as the raw materials. Petroleum and liquefying gas products can satisfy the standards of clean fuel and has large product market demands. The heat generated by the hydrocarbon production through the methanol dehydration is used for the cooling and heating electric device and can lower the carbon dioxide emission in a cooling and heating power production process.

Description

Technical field [0001] The invention relates to the technology of dehydration of methanol to produce hydrocarbons and cogeneration of cooling, heating and power. Background technique [0002] The United States Mobile Company published methanol-to-gasoline technology in 1976. The process is as follows: firstly, coal or natural gas is used as raw material to produce synthesis gas, synthetic gas is used to synthesize crude methanol, and finally clean gasoline is produced by dehydration of crude methanol. In 1984, a fixed bed demonstration plant was established in Germany. In 1985, a methanol-to-gasoline industrial plant using natural gas as raw material was established in New Zealand. The Shanxi Coal Chemical Institute of the Chinese Academy of Sciences has proposed a patented technology for one-step methanol-to-gasoline production. The dehydration of methanol to hydrocarbons is completed in one step in one reactor to make the process simple and compact. Dehydration of methan...

Problems solved by technology

[0003] The purpose of the present invention is to replace the method of driving the cold and heat electric device with diesel oil and liquefied gas by using the combined heating of methanol dehydration reaction heat and dry gas combustion, so as to solve the problem of low thermal efficiency of the existing methanol dehydration hydrocarbon production device and the carbon dioxide of the cold and heat electric device. To solve the problem of large emissions, reduce the production cost of existing cooling, heating and power plants and methanol dehydration and hydrocarbon production plants
