Purification and Enrichment Systems

ABSORPTION / DESORPTION BIOGAS PURIFICATION & ENRICHMENT TECHNOLOGIES

PECMA offered turnkey basis Biogas Purification and Enrichment system as per IS 16087:2016 and IS 15958:2012 standards.

Salient Features:

  • 100% CO2 removal with supported Amine sorbents (Absorption system with temperature swing as regeneration). 
  • 100% H2S removal to produce CBG as per IS 16087:2016. 
  • CBG/CNG production from Raw Biogas by PLC controlled. 
  • Technology based on simultaneous separation of CO2 and H2S from Raw Biogas by amine system in CO2 absorber and CO2 desorption at low temperature. 
  • CO2 removal based on specific sorbent chemical developed having high affinity of CO2.
  • Sorbent’s affinity to methane-Nil. 
  • Regeneration of Sorbent Solution by Thermal Energy. 
  • Bio-organic Catalyst developed in-house to increase stability to avoid periodic replacement as Amine sorbent has limited stability. 
  • Bio-organic catalyst developed in house also retards metal corrosion. 
  • Use of Bio-organic catalyst reduces the Energy requirements for sensible heat when switching between adsorption and desorption. 
  • Specially, developed sorbents & Bio-organic catalyst retains heat effect during absorption due to absence of evaporating water in the absorber. 
  • Historical and real time trending, Daily / Hourly Report generation having safety interlocks in PLC / DCS for automatic shut down of the plant in case of emergency conditions, PLC / DCS controller and SCADA software provided.
