Title:
メタン含有ガスの均一酸化のためのプラント、およびメタン含有ガスの酸化方法
Document Type and Number:
Japanese Patent JP2013502413
Kind Code:
A
Abstract:
The invention relates to the process for homogenous oxidation of methane-containing gas comprising feeding of methane-containing gas preheated to 430-450° C. to at least three sequentially installed oxidation reactors, wherein each reactor, with the exception of the last one, is independently connected to waste-heat boilers, the reactors are fed with oxygen for oxidation of methane-containing gas, wherein the gas mixture temperature is increased to 540-560° C. with subsequent rapid quenching-cooling of the gas mixture to 440-450° C. in waste-heat boilers where steam is formed which is fed to a rectification tower for separation of end products, from the last reactor the reaction mixture is fed to a separator, from the separator the liquid phase is fed to the rectification stage where rectified methanol, ethanol and formaldehyde are produced, and the gas phase is fed for cleaning it of SO2, CO and CO2, and in the process, partial purging of the circulation cycle is performed to remove inert gases, and after cleaning and purging the cycle is completed by replenishing the gas-phase/cycled gas with the original methane-containing gas and re-feeding, the resulting gas to the reactor. The invention makes it possible to increase efficiency, increase product yield and improve the environmental situation.
