Reliable Fuel Gas Desulfurisation Ensures Uptime

Biogas is increasingly important as source of sustainable energy. When biogas is produced through any form of anaerobic digestion, it will be mostly polluted with hydrogen sulphide. The concentrations can vary from 200 ppm up to several volume per centage points.

Removal of H2S is often required for reasons of health, safety, environment and corrosion of equipment such as gas engines, boilers and piping. Desulphurisation is also is necessary when biogas is upgraded to natural gas quality and injected in the grid.

Of the many methods available, AlfagyCleanGastm is the most elegant. This technology is very reliable (> 98% uptime) and shows deep removal of hydrogen sulphide. Importantly, the caloric value of the biogas is retained as it does not dilute biogas with air or oxygen.

AlfagyCleanGastm technology is used to desulphurise

Among many fuel gasses the Alfagy gas cleaning system, AlfagyCleanGas, can purify these gasses:

  • Biogas
  • Vent air
  • Landfill gas
  • H2S containing gases from the oil and gas industry

Using our system will ensure that the plan with last longer and increase the maintenance intervals and improve the return on investment. 

Biological gas scrubbers for biogas and AD plant

Alfagy delivers biological H2S scrubbers.  The first biological gas cleaner was commissioned more than 20 years ago. Key positions are held by engineers who have years of practical experience as operation managers on biogas plants or similar positions.  The core expertise lies in product development, sales, project management and service.  Production is carried out at a limited number of selected sub-suppliers, both in Europe, Southeast Asia, North America and South America.

Alfagy gas cleaners are installed at biogas plants where biogas desulphurisation is required. The hydrogen sulphide (H2S) is removed from the biogas in a biological process. The company’s H2S scrubbers are available in 4 different product types.

For smaller and medium sized projects Alfagy offers gas cleaners built into standard 20’ or 40’ shipping containers. This type of gas cleaners can easily and in-expensively be distributed worldwide by trucks and container ships.

Pumps, blower, PLC controller, etc., are installed in the machinery room which is positioned at the front of the container.
