Biomethane has a growing interest, as it is a substitute for methane and can be used in both the transport and power generation sectors. To allow this application, biomethane must be produced starting from biogas (a mixture of carbon dioxide and methane). There is a wide range of technologies available for this purpose. For the typical size of the biogas plants (500-1000 Nm3 / h), due to great variability in the coats and in the performances.

As being the ultimate alternative solution of energy source now it is necessary to purify the raw biogas into enriched Methane to be used as a fuel. To purify the Biogas Water is the best medium for cleaning and scrubbing biogas and this is the easiest and commonly used process in industries which is used to remove CO2 & H2S from biogas. Revgreen Pakistan has already designed and installed water scrubbers of different sizes and scale based on the production and flow rate of raw biogas

 Biogas scrubbing is the most economical and advantageous solution. an economic (investment cost) and an energy one (primary energy efficiency). Methane slip is used as an indicator of environmental performance. Water scrubbing is the most economical and advantageous solution. an economic (investment cost) and an energy one (primary energy efficiency). Methane slip is used as an indicator of environmental performance.
