The Design of Shell-and-tube Heat Exchanger in the Project of the Coal Bed Methane Electrical Power Generation

Abstract

Coal-bed-methane (CBD) electrical power generation is an active and effective measure to reduce emissions of greenhouse gases. Using shell-and-tube heat exchangers to reduce the water content of pipeline gas can improve the efficiency of the generator set. Designing heat exchanger by ASPEN EDR software can save a lot of manual calculation process, so as to improve the efficiency of the heat exchanger designer. The general method of designing and verifying shell-and-tube heat exchanger by EDR ASPEN software is described in this article by the example of the local process of low concentration gas power generation project. Because of the heat flux medium is low concentration coal bed methane with high explosion risk, anti-explosion measures must be taken to ensure safety beyond the requirements of normal heat exchangers of heat transfer, pressure drop.
