Mechanism of activated carbon desulfurizer


Activated carbon desulfurizer is one of the earliest dry desulfurizers, which has been used for more than 70 years. The former activated carbon desulfurization technology has huge equipment, complicated regeneration and sulfur recovery process, and cumbersome operation. In the 1950s, it was gradually replaced by wet method. In recent years, due to the improvement and simplification of regeneration method, activated carbon desulfurizer for fine desulfurization and room temperature fine desulfurization technology have been developed, There are many small and medium-sized ammonia plants, urea plants and methanol plants that use activated carbon desulfurizer to remove organic sulfur and part of organic sulfur in feed gas by dry method. This method has the advantages of large sulfur capacity, strong adaptability, low operating temperature, renewable, repeated use and sulfur recovery. Moreover, the price of activated carbon desulfurizer is relatively low. However, the activated carbon desulfurizer is only limited to oxygen, In terms of water resistance, activated carbon desulfurizer is better than iron oxide desulfurizer
