BioCNG, RDF and Solid Waste Management
" Covalent offers wide range of process plants for Anaerobic Digestion, BioCNG, RDF and Solid Waste management "
As fossil fuel resources are finite and are among the biggest contributors to climate change, it is critical that we meet our energy needs from renewable resources. India's renewable energy resource potential is significant, with solar, wind, biomass, and small hydropower representing the technologies having the largest potential. Among all, biomass demands a special attention. All the living matter present on earth derived from growing plants including algae, trees, and crops or from animal manure is called biomass.
In India traditionally biomass had been utilised either through direct combustion or anaerobic digestion. Anaerobic digestion of biomass is the process in which organic matter, in the absence of oxygen, is mainly transformed into a mixture of methane and carbon dioxide which is usually referred to as biogas.
We specialise in Engineering, Procurement, Construction, Operation and Maintenance of Large and Medium capacity projects in Biomethanation, Compost, Refuse Derived Fuel (RDF), and Waste to Energy Plants, Plastic to Fuel, Scientific Landfill (SLF), Bioreactor Landfill, and Capping of existing dumpsites.
Biogas upgrading or purification is the process by which contaminants in the raw biogas stream are absorbed or scrubbed, leaving more methane per unit volume of gas. This final product is called biomethane. The most widely used technologies for biogas upgrading are water scrubbing, Pressure Swing Adsorption, membrane, and chemical scrubbing. Of these technologies, water scrubbing and Pressure Swing Adsorption are considered to be most appropriate on a small scale due to low cost and easy maintenance. Biomethane can also be compressed and bottled into cylinders and it is called Bio-Compressed Natural Gas (Bio-CNG) or simply Compressed Bio-Gas (CBG).
