Abstract:
Aiming at current situations and characteristics of the sulfur recovery unit in Qijiang Branch, the process gas reheating methods were determined. The advantages and disadvantages of five kinds of reheat methods technology were analyzed including high temperature mixed, reheating furnaces, steam heating, gas-gas heat exchanger and electric heater. The electric heater was finally determined because of the advantage of convenient energy service, compact structure, automatic temperature control, simple operation and no pollution. The Results showed that system temperature was in normal range and sulfur recovery unit ran properly when the sulfur recovery unit operated at low load. Meanwhile, the common problems and abnormal situations of electric heater were analyzed and summarized.
