“CO2 capturing compressor to
separate methane from biogas and
landfill gas”
Dr Amit Roy
CEO
Dirty-wet gas compression + scrubbing + drying in a single step to
produce bio-CO2 & CNG fuel from biogas. (no membrane, no PSA)
Near Iso-thermal compression, no cooling required.
No moving parts in the compression chamber.
Robust, rugged, 98% volumetric efficiency.
90% less footprint,
70% lower cost,
50% greater overall efficiency.
ultra light weight, made of inert HDPE pipes.
Scalable to 1000 kg CNG /day plants.
Innovations
Biogas CH4, CO2, H2S,
NH3, siloxanes,

Which problems do we solve
Problems:
1. Raw biogas cannot be compressed or transported without costly gas-purification. This
resulted into vast amount of stranded feedstock, or biogas/landfill gas being wasted/flared.
2. Back up power/energy storage is expensive using batteries. Diesel gensets are polluting.
Solutions
1. Engas UK offering a complete package: i) biogas upgrading, ii) compression, iii) injection to gas
grid, iv) refueling & v) power generation using bio-CNG at a much lower cost.
2. Build, own, operate plants along with stranded gas owners to sell biomethane and electricity.
Rapid production capability
Why the customer should buy it
• Input: 500 Nm3/h raw biogas.
• Purified to 4500 kg / day biomethane.
• Application: refuelling
• 1kg CNG ~ 1lt diesel, so saving £1/kg CNG, so saving up to £1575,000 / year.
• Additionally there is £0.71 RTFC income / kg bio- CNG (waste derived). So further up to
£1102,500 income through RTFCs.
Total potential value of bio CNG= £2677,500 / year to pay for the Capex/ Opex.
Different types of Bio-CNG plants
Installed in India Containerised UK based plant Exporting multiple
units for India
