Coal gas recovery and purification technology and equipment
Coal gasifier is a traditional industrial fuel. In recent years, industrial energy conservation and emission reduction requirements have caused coal gasifier to be replaced by natural gas and other clean energy, while the domestic natural gas resources are limited and the price of natural gas is rising. The recovery and utilization of coal gasifier has become an important way to meet the need of gasifier industry.
Coal gas recovery and purification technology mainly includes the following four parts: coal gas purification, gas gathering, gas storage and gasification. The coal gas recovered by this technology and equipment can be used as combustible gas (EG), producer gas (PG) and coal tar raw material.
The first step of coal gas recovery and purification technology is coal gas purification. In this process, small molecules such as oxygen, nitrogen, carbon dioxide and hydrogen sulfide will be removed from the coal gas. After purification, the combustible gas content of coal gas can be increased by several times. In order to achieve this goal, there are two commonly used methods. The first is the air adsorption method, which uses desiccant or adsorbent to removing compounds in coal gas such as oxygen, nitrogen, water vapor, carbon dioxide and sulfur dioxide. The second is the steam absorption method, which directly condenses the steam in the coal gas to remove oxygen.
The second step is gas gathering and storage. In this step, the purified coal gas is sent to gas gathering point. The gas gathering point can be a steel pipe network or a container. In this way, the coal gas can be distributed to different industrial places according to their needs.
The third step is gasification. After the collection and storage of coal gas, the last step of coal gas recovery and purification is gasification. Gasification involves the conversion of coal gas into usable forms, including producer gas, diesel oil, producer gas and coal tar raw material.
Coal gas recovery and purification technology and equipment involve a large number of complicated technologies and involve different kinds of equipment, such as purification and desulfurization equipment, collectors, filter-separators, industrial steam boilers and gas boilers.
PuriTechs coal gas recovery and purification system is one of the best and most efficient systems. This system uses low-temperature desulfurization process, which can effectively separate impurities while maintaining the stability of the coal gas. It achieves a purification rate of up to 97%. It also includes a filtering system, ensuring that the coal gas is free of suspended particles or droplets. The gasification process is also managed by an automated system, which ensures that the quality of the coal gas is constant and up to the standard.
In addition,puritechs coal gas recovery and purification system also has the advantage of safe and reliable operation. The entire system is designed with strict adherence to automation standards, which ensures that any malfunction or failure can be reported and addressed quickly.
Coal gas recovery and purification technology and equipment not only enable coal gasification companies to reduce their cost, but also contribute to promoting clean production and reducing exhaust emissions. With the application of coal gas recovery and purification technology and equipment, industries can reduce carbon emissions and pollutants, increase energy efficiency and reduce their environmental impact.
