[0003] However, due to the small calorific value of the gas released by this chemical industry, at 8.27MJ / M 3 ~9.8MJ / M 3 Between, so that the scope of application of this chemical purge gas is limited
At present, the application of chemical exhaust gas is mainly to recover the hydrogen in the exhaust gas, or to use it for boiler combustion. Some manufacturers even discharge the gas directly to the air, so that this chemical exhaust gas cannot be fully utilized.

Abstract

The invention discloses a system for generating power by applying chemical purge gas, comprising a device for generating methanol by using coke oven gas and a power generation device, wherein the device for generating the methanol comprises a chemical purge gas outlet end, and the power generation device is provided with a chemical purge gas inlet end which is connected with the chemical purge gas outlet end. The system which is provided by the invention and used for generating the power by applying the chemical purge gas has a simple structure, is practical, brings a novel application way for the chemical purge gas, and can be used for improving the value and producing the economical benefit. Meanwhile, the invention also provides a method for generating the power by applying the chemical purge gas.

Description

technical field [0001] The invention relates to a system and method for generating electricity by using chemical exhaust gas. Background technique [0002] In my country, there are many million-ton coking plants that use the coke oven gas produced to produce methanol, and the production of chemical off-gas is associated with the synthesis process of methanol. This kind of chemical exhaust gas has high cleanliness, less corrosive impurities, and its main component is hydrogen (H 2 ), the content of hydrogen is about 70% of the chemical industry vent gas. At the same time, this kind of chemical release gas has the advantages of relatively stable gas source and high discharge pressure. [0003] However, due to the small calorific value of the gas released by this chemical industry, at 8.27MJ / M 3 ~9.8MJ / M 3 Between, so that the scope of application of this chemical purge gas is limited. At present, the application of chemical exhaust gas is mainly to recover the hydrogen in...
