What is a biogas compressor?

Simply put, the function of biogas compressor is to change low-pressure biogas into high-pressure biogas by compression, so as to facilitate subsequent transportation, storage or use.

Core special requirements include:

Protection requirements: The main component of biogas is methane, which belongs to flammable gas. Therefore, the compressor and its motor must meet the safety standards to prevent sparks from causing safety accidents during operation.

Anti-corrosion treatment: unpurified biogas contains hydrogen sulfide, which will form a highly corrosive acid when it meets water. The flow passage, cylinder, valve and other parts of the compressor that contact with biogas need to be made of corrosion-resistant materials or specially coated.

Sealing: It must have extremely high sealing to prevent high-pressure methane leakage, which not only ensures safety, but also reduces energy waste.

Lubrication mode: If it is used in the subsequent fine chemical industry or places with high requirements on gas purity (such as merging into natural gas pipeline network), oil-free lubrication technology is usually adopted to prevent lubricating oil from polluting gas or blocking subsequent equipment.

To sum up, biogas compressor is the "heart" equipment in biogas engineering, which is responsible for providing "power" for biogas so that it can flow and be effectively used.
