Problems solved by technology

At present, in order to solve the water problem, the water cooler is changed to air cooling in these systems, but the equipment is huge and consumes a lot of power, and it cannot meet the process requirements when the ambient temperature is high in summer, so only a water cooler can be used to meet the process requirements

Abstract

The invention pertains to the cooling and condensation technology of methanol production. A heat exchanging equipment outside a tower of the provided methanol production process adopts an evaporation air-cooled cooler to respectively carry out heat exchanging treatment for virgin gas at different levels in a compression section and mixed gas out of a synthesis tower; gas methanol from a pre-rectification tower and gas methanol from an atmospheric tower are condensed as liquid methanol by adopting an evaporative water cooler; an arranged multicell combination heat exchanger has a plurality of independent heat exchanging cells; multiplex process fluids of the methanol production are respectively treated by condensation and cooling. The heat exchanging equipment provided by the invention can improve the condensation and cooling effect of heat exchanging outside the tower in the methanol production; heat transfer efficiency, testified by practice, can be improved by more than 10 percent, thereby reaching the function of saving energy and reducing consumption.

Description

technical field [0001] The invention belongs to the methanol production cooling and condensation technology, and mainly relates to an external heat exchange equipment in the methanol production process. Background technique [0002] In the methanol production process, water gas or other raw material gas is purified and then compressed. The raw material gas is compressed in multiple stages to gradually increase the pressure of the outlet gas to meet the process requirements. After each stage of compression, the process gas must be cooled to make it The temperature is lowered to the process requirement, and then the next stage of compression is carried out. In the compression process, the heat exchangers for intermediate cooling at all levels are all water-sprayed cooling pipes. In the synthesis process, the crude methanol is condensed, that is, the raw material gas reaches the process state and then enters the synthesis tower for catalytic reaction, and the mixed gas exiting...
