A Design for a workshop process that annual output of 300000 tons of H2 and primary heat exchanger
 

Abstract: This design introduces in detail the shiftprocesses of carbon monoxide of synthesis ammonia production home and abroad, and the requirements for the raw material. It comparea and analyzea the differences of shiftprocesses basing on technological economy. This design adopts total low temperature shiftprocess. On this basis, Based on this, annual output of 300000 tons of H2 was designed. The design  mainly contains the material accounting of material purification section, process calculation of primary heat exchanger, and the diagrams including the equipment drawing of primary heat exchanger and process flow diagram for synthesis ammonia production. Besides, there also is a simple economic cost accounting, introduction of safe operation of shiftworkshop of carbon monoxide, method about disposal of industrial waste (waste gas, waste water and industrial residue) during the production of synthetic ammon in the design.

Key words: process, synthesis ammonia production, shiftprocesses of carbon monoxide, primary heat exchanger.
