1. Natural gas generator set: the generator set with natural gas as fuel. The main combustible component of natural gas is methane CH4. Methane concentration is generally between 70% and 97%. Natural gas is mainly produced by tail pipe of associated gas process after recovery of gas well or light hydrocarbon. Natural gas generator units are mainly used in gas fields with rich natural gas resources, light hydrocarbon recovery enterprises and enterprises with access to natural gas along the natural gas pipeline.
2. Oil associated gas generator set: the combustible components of oil associated gas mainly include CH4, C2H6, C3H8, C4H10, etc. Methane CH4 is the main component. Its content is generally about 80%. Associated gas comes from oil wells. Therefore, associated gas generator set is mainly used in associated gas oil field.
3.发生炉煤气发电机组:发电机组的燃料是发电机组的气体。煤气中二氧化碳和水蒸气少氧气室炉膛集成通过氧化还原反应的进行,煤气公司主要可燃成分,H2,此外,还有少量的甲烷CH4, CO含量一般在25% - 35%,H2含量一般在6% - 10%的甲烷含量一般在2% - 6% CnHm含量一般在0.5% - 3%的平均煤气含有很多硫、苯、奈,焦油、水分和灰分、硫、苯、奈,焦油,燃气发动机运行时，发电机气体进入发电机组前必须进行预处理。
3. Generator gas generator set: the fuel of generator set is the gas of generator set. The integration of carbon dioxide and water vapor in the gas is carried out by oxidation-reduction reaction. The main combustible component of the gas company is H2. In addition, there is a small amount of methane CH4. The content of CO is generally 25% - 35%. The content of H2 is generally 6% - 10%. The content of methane is generally 2% - 6% and the content of CnHm is generally 0.5% - 3%. The average gas contains a lot of sulfur, benzene, Nai, tar, water and ash, sulfur, benzene During the operation of, Nai, tar and gas engines, the gas of the generator must be pretreated before entering the generator set.
4. LPG generator set: the generator set is fueled by LPG. The main components of LPG are propane C3H8 and butane C4H10. LPG is mainly produced in light hydrocarbon recovery enterprises.
5. The blast furnace gas generator unit uses coking gas, blast furnace gas and converter gas, which come from the steelmaking plant and ironmaking plant. After dedusting, desulfuration and demisting treatment, it will be sent to gas generator unit for power generation.
Suggestions for biogas purification by biogas generator:
Methane purification system includes: gas water separator, sand filter and desulfurization device.
2. The quality index of methane treated by the purification system shall meet the following requirements:
A) Methane content is more than 55%;
B) Hydrogen sulfide content is less than 20mg / m3.
Water vapor in methane is usually dehydrated by gravity. For biogas projects with a production of more than 1000m3 / D, dehydration processes such as cold separation, solid adsorption and solvent adsorption can also be used.
4. The biogas gas water separator can be designed according to the following parameters:
A)进入气水分离器的甲烷量按日甲烷量计算;B)气水分离器内甲烷供气压力大于2kPa;C)气水分离器压力损失应小于100Pa;D)气水分离器气缸高度为直径的4 ~ 6倍;E)气水分离器应配备自动排水装置。
A) The amount of methane entering the gas-water separator is calculated based on the daily amount of methane; b) the pressure of methane supply in the gas-water separator is greater than 2KPa; c) the pressure loss of the gas-water separator is less than 100Pa; d) the height of the air cylinder of the gas-water separator is 4-6 times of the diameter; E) the gas-water separator shall be equipped with automatic drainage device.
