WBA Training: Biogas Upgrading Technology/Opportunities

24. 5. 2022 09:00 - 11:00 CEST

biogas station

24 May, 9:00 AM – 11:00 AM BST

Choosing the best technology solution for your biogas upgrading

Trainer: Mario A. Rosato

Blog: Biogas and independence from Russian gas: will Spain beat Italy on time? Click here to read the full blog from Mario A. Rosato

Learning outcome: To provide an overview of the different biogas upgrading technologies, the pros and cons of each and how to select the best technology in different scenarios

09:00 Differences between cleaning and purification of biogas

  • The thermodynamic benchmark:  the ideal Van t’Hof machine in the case of perfect and imperfect gas separation
  • Minimum work and minimum heat of imperfect separation
  • The ideal work of compression
  • The ideal work of liquefaction

10:00 Comparing different real-life processes under different operational conditions: case study.

a) Dry upgrading technologies

  • Activated carbon (PSA, pressure swing adsorption)
  • Engineered zeolites
  • Bed-packed amines
  • Selective membranes

b) Wet upgrading technologies

  • Water scrubbing
  • Water/PEG scrubbing (Selexol process)
  • Alkaline scrubbing (Benfield process)
  • Amine scrubbing
  • Solvent scrubbing (Rectisol process)

c) Emerging technologies

  • Cryogenic upgrading
  • Bioupgrading
  • electromethanogenesis

10:40 Selection of the most suitable process in each context

A summary of each technology and how to assess which process is most suited to your project
