High temperature shift converter
In order to take advantage of both the thermodynamics and kinetics of the reaction, the industrial scale water gas shift reaction is conducted in multiple adiabatic stages consisting of a high temperature shift (HTS) followed by a low temperature shift (LTS) with intersystem cooling. The initial HTS takes advantage of the high reaction rates, but results in incomplete conversion of carbon monoxide. A subsequent low temperature shift reactor lowers the carbon monoxide cont… WebDec 20, 2014 · As Mr. Bobby Strain mentioned we are using MTS convertor (Medium Temperature Shift) and LTS (Low Temp Shift) as a polishing bed downstream. we sometimes bypassed the LTS to do trials, eventually the methanator downstream of shift convertors took a big temperature hit due to CO Slip.

WebThe rest of the gas passes down through a top layer of catalyst in an axial direction, eliminating the need for a top cover on the catalyst bed. Casale’s axial-radial catalyst bed technology is used in both high-temperature and low-temperature shift converters, as well as in the synthesis converter. Other technologies WebTwo basic types of catalyst are normally used for shift conversion, depending on the temperature at which the reaction is carried out. The high temperature catalyst is typically chromium-promoted iron oxide, which is active within the …
