MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202511115531 A) filed by Jaypee University Of Information Technology, Solan, Himachal Pradesh, on Nov. 22, 2025, for 'a system and a method to remove water vapour from biogas in low-cost reactors.'
Inventor(s) include Karam Dass; Sudhir Kumar; and Ashish Kumar.
The application for the patent was published on Jan. 9, under issue no. 02/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a system and method to remove water vapour from biogas produced in domestic or community-scale reactors. The system comprises a container made of plastic or PVC material fitted with galvanized iron (G.I.) components such as a gas inlet, gas outlet, and a drainage port. An absorbent medium, preferably cotton, is arranged inside the container to capture and retain moisture through condensation and capillary absorption as wet biogas passes through. Further, the outlet is positioned above the inlet which ensure that only dried biogas exits the system, while condensed water is periodically removed through the drainage port. The method further operates passively, without external power or chemicals, using thermal and gravitational principles to separate water vapour efficiently. As such, the present system offers a low-cost, maintenance-free, and eco-friendly solution that enhances the combustion efficiency and reliability of biogas for domestic and small-scale energy applications."
