Because some gas heating processes have strict requirements on the sulfur in the atmosphere, the cold clean gas needs to be desulfurized before it can be transported to the gas point. The current gas desulfurization processes mainly include dry desulfurization processes and wet desulfurization processes.
Dry desulfurization: Dry desulfurization has a simple, mature and reliable process. It can remove hydrogen sulfide in coal gas, but also remove cyanide, nitrogen oxide and tar mist, with a high degree of desulfurization and purification. Currently, activated carbon and activated artificial iron oxide are mainly used as desulfurizers.
Dry desulfurization process
Wet desulfurization: Wet desulfurization can be divided into three types: physical absorption method, chemical absorption method and direct conversion method. The wet desulfurization process is mainly composed of two parts: absorption and regeneration. The purpose of absorption is to absorb hydrogen sulfide in the coal gas with an absorbent to make the desulfurized coal gas meet the requirements of the process regulations. The regeneration part restores the absorbent that has absorbed hydrogen sulfide and recovers its content. Sulfur.
Wet desulfurization process
Due to the instability of gas consumption (intermittent production, large fluctuations in gas consumption) and the continuous production characteristics of mixed gas generators, it is necessary to establish a gas tank to store gas. The establishment of a gas tank can reduce the time of hot preparation of the furnace and save fuel.

A certain amount of phenol-containing sewage will be generated during the operation of the gas station, which will pollute the environment and endanger your health. It must be treated. A phenol water incinerator is built. The self-produced gas or tar is used as fuel to heat and decompose phenol water. Phenol water is decomposed in a high-temperature atmosphere. Generate CO2 and H2O, meeting the requirements of harmless treatment.
