TLDR
In this article, a method for regenerating a converter gas variable temperature adsorbent for the production of methanol from a coke oven gas and converter gas was proposed.Abstract:
The invention relates to a methanol preparation technology in the chemical industry field, and concretely relates to a method for regenerating a converter gas variable temperature adsorbent for the production of methanol from a coke oven gas and a converter gas. The method comprises the following steps: introducing a methanol relief gas or a tail gas obtained after hydrogen extraction of the methanol relief gas into a regenerated gas heat exchanger in the variable temperature adsorbent regeneration process of the converter gas in order to realize the heat exchange heating of the methanol relief gas or the tail gas obtained after hydrogen extraction of the methanol relief gas and a regenerated gas, introducing the regenerated gas into a regenerated gas heater, heating, introducing the heated regenerated gas to a converter gas variable temperature adsorber for regenerating an adsorbent for regeneration, introducing a gas from the converter gas variable temperature adsorber into the regenerated gas heater for heat exchange cooling, introducing the obtained gas into a water cooler for cooling, and sending the cooled gas to a fuel tube network as a fuel. The method avoids wastewater generated through steam regeneration to realize sewage treatment reduction, and allows energy saving and consumption reduction to be realized by reducing regeneration heat consumption and reducing cooling water consumption via adopting the heat exchange of the regenerated gas and a regeneration gas.read more
