We provide H2S Scrubbing solution for 100 CUM per hour onwards
Industrialization and urbanization of the society in the present world has increased the levels of pollution in all the three sectors, land, air and water due to the wastes generated. Proper treatment and disposal of the same in order to prevent the damage to the natural resources and the environment is being recognized and pursued at various degrees of seriousness around the world. Different methods are in vogue depending on the type of waste, whether it is biodegradable or non-biodegradable. One of the most common and effective way of treating the biodegradable matter is anaerobic digestion and is infact part of most of the distillery effluent treatment plants and sewage treatment plants. Biogas the product of anaerobic digestion is a mixture of Methane, Carbon dioxide and Hydrogen sulfide. The composition of biogas is mainly Methane, CH4 (55-65 %), Carbon dioxide, CO2, (30 - 40 %) and hydrogen sulfide, H2S, (0 - 6 %) depending on the type of waste and the temperature of the digester used. The calorific value of biogas is around 24 – 28 MJ/ m3 (depending on the CH4 content in the gas) and is a potential and efficient fuel source for power generation using IC engines, if the hydrogen sulfide is removed from it.
Hydrogen sulfide is a highly toxic and corrosive gas and is a major pollutant in fossil fuel based industries, sulfur based chemical Industries and biogas based units Sweetening of biogas is essential because of its toxicity which affects the environment and the highly corrosive nature which corrodes the metallic parts like boiler tubes, engines coming in contact with it in few hundred hours of operation.
To provide gas cleaning process to the industries and also to provide a single point contact from gas cleaning to power generation on biogas, Green Power International (P) Ltd. has entered into an association with Indian Institute of Science, Bangalore (IISc) for providing H2S Scrubbing Systems.
The ISET Scrubber Systems generate up to 96 % pure elemental sulfur from biogas. No additional ETP etc. is required as this is a zero liquid discharge system. The system can be designed in modular sizes with minimum installation area and there is no pressure drop throughout the process in this system.
