With the issue of some national environmental policies and regulations, the demand for flue gas of heat-engine plant gets more and more strict, which promotes the development of various desulfurization technologies. Among them, magnesium desulfurization technology obtains much attention since it is mature, economic, recycled and environmental. It has been widely used in such countries like America, China, Germany and Japan. In Taiwan, China, 95% of power plants has started to use magnesium desulfurization technology. Magnesium desulfurization technology can achieve by-products recycle, protecting environment and improving the sound develop of industrial structures.
This desulfurization system is composed of absorber preparing system, flue gas system, SO2 absorbing system, process water system, electrical instrumental system and by-product recycling system. The technological process is as follows:
The desulfurization projects occupy a few floor areas. The investment is lower.
The desulfurization process is stable. It is free from some problems like blocking.
It hardly produces something bad for the environment.
The by-products can be used again in avoidance of unnecessary wasting.
Promising economic benefits
The magnesium desulfurization is profitable because the desulfurizing agents can be used repeatedly which lowers the desulfurization costs so as to increase economic profits.
