Iron complex desulfurization has the characteristics of large absorption capacity of sulfur, high desulfurization efficiency, fast speed of sulfur extraction and oxidation regeneration, easy recovery of sulfur, pollution-free desulfurizer, and has been experienced in industrial application.
Iron complex desulfurization process can achieve 99.9% H2S removal rate in many industrial fields, including natural gas extraction, crude oil extraction, petroleum refining, biological gas treatment, chemical sulfur gas and coke oven gas, etc.
In these industrial processes, the gas to be treated capacity from a few cubic meters to tens of thousands of cubic meters, and the sulfur produced every day ranges from a few kilograms to dozens of tons.
The H2S content of the gas treated by the complex iron system is less than 1PPmV.
(1) The H2S removal rate is high, the first step reaction removal rate is more than 99.99%, and the concentration of H2S in the treated tail gas is below 1 ppm.
(2) Wide application range, can deal with a variety of H2S gas.
(3) The operation is flexible and can adapt to the large fluctuation of H2S concentration and flow rate of raw gas from 0 to 100%.
(4) Environmentally friendly, no three wastes produced.
(5) Mild reaction conditions, liquid phase and normal temperature reaction process.
(6) Simple process, plant running/stopping and daily operation are simple.
(7) High economic performance, small footprint, less investment costs and low daily operation costs.
(8) High safety performance, the system does not use any toxic chemicals and the sulfur products are without H2S gas.
