1. It consists of changeable H2S filter
2. While the amount of H2S attached to the filter increases, the pressure shown in the pressure gauge also increases
3. Once filter is fully saturated, it needs to be replaced.
4. H2S should be removed completely as it causes corrosion on the wall of vessels used.
Biogas compressor
Specification
Type: Oil-free piston
Design Pressure: 15 bar
Design temp: 50 degree centigrade
Material: Mild Steel
Flow rate: 100L/min
Power 380VAC 3 phase 50Hz (0.374kWh)
Function: To compress the biogas coming out of H2S filter and increase the pressure up to 2~3 bar which is required for PSA system.
CNG buffer drum
Specification:
Type: Vertical Cylinder
DP/DT: 15 bar/ 50 degree C
Volume: 30 L
Function: Collect slightly compressed gas before sending to the purifier (PSA)
It maintain continuous flow of gas to the purifier
It prevents from popping and irregular strike of biogas to purifier.
Electric circuit and signal transfer
It receive signals from all devices of purifier and transfer it to the control panel.
Digital signals can be seen in PLC system and operation condition can be observed by the notification of LED (light) in the graphic board.
