1、 Overview
With the rapid development of anaerobic technology, efficient anaerobic devices have been successfully applied in various organic wastewater treatment projects. While organic matter is effectively removed, a large amount of anaerobic gas - biogas - is produced. The main component of biogas is methane, which is a type of methane

A highly flammable gas with a calorific value of approximately 37.84 KJ/L. When the methane content in biogas is 60%, the calorific value of biogas is about 22.7KJ/L. Therefore, biogas has been fully utilized, either for power generation or for boiler combustion. Becoming a cycle of enterprise development

An economic model, but the composition of biogas is complex, with the main harmful substance being hydrogen sulfide. Depending on the digestion reaction raw materials, the hydrogen sulfide content in each cubic meter of standard gas varies, ranging from a few hundred milligrams to tens of thousands of milligrams. This will have an impact on biogas production

Gas generators and boilers cause corrosion, affecting the service life of the equipment. The direct emission of gases after combustion will cause pollution to the atmosphere, so biogas must be pre treated before use to meet the usage conditions of various equipment.
Our company has been engaged in the development of anaerobic technology for a long time, and based on the digestion and absorption of domestic and foreign wet flue gas desulfurization technologies, we have successfully developed LVCL type wet flue gas desulfurization technology.

2、 Basic principles of LVCL wet flue gas desulfurization process

LVCL wet flue gas desulfurization technology is a desulfurization technology that oxidizes hydrogen sulfide in biogas into elemental sulfur in a liquid phase containing a catalyst. In this process, it is divided into two steps; Absorption and regeneration.
The absorption process mainly occurs in the desulfurization tower, while the regeneration process mainly occurs in the regeneration tank.

4、 Characteristics of LVCL wet flue gas desulfurization process

1. High desulfurization rate, with a desulfurization rate of over 98%;
2. Small side reactions and low probability of generating sodium thiosulfate;
3. The nozzle atomization rate is high and there is no blockage;
4. The utilization of efficient dehydrators results in low moisture content of purified biogas;
5. High operating costs and significant economic benefits;
6. High degree of automation, simple operation, and easy maintenance.
