Technology for the purification of biogas under the trade name Biosulfex ®

Blog page

Technical features:

For sewage treatment plants, agricultural biogas installations, waste depots and other enterprises producing biogas wanting
to use this gas in the production of heat and electrical energy while seeking an effective method of removing hydrogen sulphide (as well as dust and siloxane), we present BIOSULFEX®. Unlike competing solutions, it delivers an exceptionally effective technological process that removes hydrogen sulphides, leaving amounts as small as a few ppm.

Removal of hydrogen sulphides using BIOSULFEX®, prevents corrosion of pipelines and boiler elements, helping to eliminate outages of such equipment. The treatment process also eliminates the threat of poisoning by toxic hydrogen sulphide.  BIOSULFEX® is tailor-made to the needs of each client. Its efficiency is in excess of 99 %. The only by-product of the process
is sulphur pulp, which is also a very valuable raw material. BIOSULFEX® can also be equipped with elements for removing dust and siloxane. It is also possible to install a multi-gear version of the unit, allowing for more cost-efficient operation of the unit when it is used less intensively. The unit does not require constant hands-on operation, is compact, offers easy maintenance, and is also made from high-quality materials.

During 20 years of operations, Zespół Innowacyjny PROMIS has produced over 20 units. The primary recipients of the technology are sewage treatment plants. BIOSULFEX® units are in operation in places such as Warsaw, Szczecin, Kraków, Mińsk Mazowiecki, Puławy, Siedlice, Opole, Grudziądz and Raszków near Ostrów Wielkopolski. The volume of biogas produced by the units currently in operation ranges from 50 m3/h to 2 250 m3/h.

Advantages of the technology:

  • Over 99 % efficiency in removal of hydrogen sulphide, to as little as
    a few ppm.
  • BIOSULFEX® technology does not create wastes nor does it emit harmful
    substances into the atmosphere.
  • Very small quantity of by-product (sulphur pulp) which is a muchsoughtafter
    raw material.
  • Patent-protected technology.
  • The unit is very cost-efficient.
