Applications: Biogas, a renewable gas is composed of 55-65% methane (CH4) and 35-45 percent Carbon Dioxide (CO2). It is obtained during anaerobic fermentation of organic waste. CH4 makes it a combustible fuel while CO2 restraints its compressibility and calorific value. Among the biogas cleaning and upgrading methods, water scrubbing is the most feasible method. The present invention relates to water scrubbing based production of biomethane and biocarbon dioxide from biogas. An economic, simple method of construction, physical absorption based water scrubbing system was designed and developed for recovering maximum CO2 from the secondary gas stream of water scrubbing based biogas upgradation plant. The system is designed to recover CO2 and CH4 loss from secondary gas stream having CO2 (88-90%) and CH4 (10-12%) of pilot scale water scrubbing biogas upgradation plant. The method is capable of producing pure CO2 from the secondary gas stream of biogas upgradation plant. Key Features: 1. This system is capable of producing bioCO2 (pure CO2: 99.99%). 2. The system does not produce loss of gases but instead recovers the CH4 loss of the biogas up gradation plant. 3. This system works on low flow rate and medium pressure for CO2 absorption from off gas stream in water scrubbing process. 4. This method is carbon negative technology. 5. It is a method with high CO2 separation efficiency Applications: 1. In Algae cultivation 2. In manufacturing and synthesis of chemicals or in warehouses as a fumigant 3. In green house and anaerobic digester to provide CO2 rich environment 4. In warehouse as fumigant 5. Biomethane, as a substitute for natural gas applications 6. Best suited system for small scale as well as rural applications.
Advantages: 1. No heat is required during absorption or regeneration process 2. No chemical is used during the process 3. Water is used as a solvent makes the whole process economic 4. This system does not require a pre-cleaning of H2S, since solubility of H2S is higher than CO2 in water and the regeneration of water process is easily accomplished by the release of pressure. 5. This is cost effective and simple method in construction and operation.

It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
