Simulation Research on the Coke-oven Gas Pressurized Desulfurization Process

After a research on the existing HPF process, this paper presented a new pressurized desulfurization process, which solved low desulfurization efficiency of HPF process and applied a more simple process. The new process was simulated and optimized on the process simulation software, the operating factors of tow columns such as flow of desulfurization solution, desulfurization tower pressure, stripping tower cold-hot feed match, flow of sour gas, side withdrawing position, are studied, the best operating condition was found. The results of simulation were in good agreement with the practice.
