Purifications - AirScience Dehumidification System
Depending on the utilization of the biogas or biogas derived natural gas, different degrees of dehumidification will be required. Generally the dew point required are as follows: Use in internal combustion engine for electric power generation: Dew point less than 12°C @ 1 atm. Use as low pressure pipeline gas for residential/industrial use: Dew point less than 5°C @ 1 atm. Use as CNG for motor vehicle: Dew point less than -10°C @ 1 atm. Use as LNG: Dew point less than -165°C @ 1 atm.

AirScience - Subcooling and Reheating Process System
The process consist in cooling the biogas to a temperature lower, by a few degrees, than the desired dew point temperature, to condense the humidity along with desolved compounds such as hydrogen sulfide and siloxanes as well as low boiler hydrocarbons. The gas is then re-heated to the desired temperature through a compression stage ...

AirScience - Model VPSA - Vacuum Pressure Swing Adsorption Process System
This process is primarily used for the dehumidification of biogas destined to the production of compressed natural gas (CNG) whether for transportation CNG or pipeline CNG. The process is very similar to the VSA process with the exception that the feed gas is under pressure and that the desorption sequence is designed to minimize the loss of methane as well as the energy usage (loss of ...
