Petrochemical enterprises produce a large amount of refining tail gas during the refining process or other production processes. These exhaust gases mostly contain combustible components such as hydrogen, carbon monoxide, small amounts of methane, and other hydrocarbons, as well as other gases such as carbon dioxide, nitrogen, and oxygen. Some industrial enterprises such as steelmaking and ironmaking also produce a large amount of industrial exhaust gas during the production process, with the gas composition and refining exhaust gas composition being roughly the same.
The composition of refining tail gas (industrial tail gas) is complex, and the reusability of enterprises is low. The vast majority of it is burned through torches, resulting in environmental pollution and serious waste of resources. In today's social situation that advocates environmental protection and conservation, it has become an urgent problem to be solved. These refining and chemical exhaust gases (industrial exhaust gases) contain a large amount of combustible gases that can be utilized for power generation through internal combustion power generation units, which not only reduces environmental pollution caused by exhaust gases but also provides a continuous supply of electricity to enterprises.
Main components of refining tail gas (industrial tail gas):
Due to different enterprises and production processes, the composition of the tail gas produced varies greatly. The main available components are hydrogen, carbon monoxide, a small amount of methane, and other combustible components such as hydrocarbons, as well as other gases such as carbon dioxide, nitrogen, oxygen, etc. The hydrogen content in this type of exhaust gas is often high, and this gas is particularly suitable for gas generator sets to generate electricity.
Advantages of Refinery Tail Gas (Industrial Tail Gas) Generator Set:
1. The refining tail gas generator unit has the advantages of large cylinder diameter, long stroke, and large displacement, suitable for low calorific value gas power generation, and can ensure continuous and constant output power of the unit.
2. The unit adopts an internal mixing intake system and an air fuel ratio automatic control system, completely avoiding the problem of high hydrogen gas backfire and blasting. Prevent backfire and ensure safe gas transmission.
3.自然吸气，确保燃气输送安全，气源的压力只需大于 2kPa 即可，使燃气机组的适用范围更广，对燃气中焦油的适用性强，气源低压输送更安全。自吸式进气，气体混合后直接进入燃烧室，不需要涡轮增压器、中冷器等进气环节，部件少，自然减少了故障率。
3. Natural suction ensures the safety of gas transmission. The pressure of the gas source only needs to be greater than 2kPa, making the gas unit more suitable for tar in the gas and safer for low-pressure transmission of the gas source. Self priming intake allows the gas to mix and enter the combustion chamber directly, eliminating the need for intake components such as turbochargers and intercoolers. With fewer components, the failure rate is naturally reduced.
4. The ignition system of the gas unit adopts ignition systems imported from the United States or Germany, ensuring controlled ignition, obtaining high ignition energy and precise ignition time, making work more thorough, energy greater, and explosive.
5. The detachable intake valve box allows for easy maintenance of the intake valve and cleaning of tar without disassembling the cylinder head.
6. Low speed ensures the service life of the unit, ensuring an annual operation of 8000h and a maintenance cycle of 60000 hours.
7. The unit can have manual and automatic parallel and grid connection functions, as well as island operation, and can achieve remote monitoring and operation functions
