BIOSULFEX®

BIOSULFEX® technology is designed for biogas purification. BIOSULFEX® removes the H2S - a poisonous gas component and corrosive to equipment and piping. Desulphurization has achieved H2S removal efficiency even up to 99,99 %. BIOSULFEX® device can also remove dust and siloxanes from the biogas. BIOSULFEX® technology is patent - protected.

BIOSULFEX® process reduces the amount of produced waste almost to theoretically possible minimum as hydrogen sulphide is converted to elemental sulphur only (not to sulphides, sulphites, and other sulphur components - not to speak about iron ore with no more than few per cent of sulphur within) and one has to realise that elemental sulphur has the minimum possible mass of all sulphur compounds to be produced of a unit mass of hydrogen sulphide.

Twenty years of improvements in the catalyst production meant its selectivity and durability in the industrial practise: our catalytic solution coverts hydrogen sulphide to elemental sulphur only: it means no by products in working solution and no effluents.

BIOSULFEX®PROCESS

Developed for treatment of various kinds of off air, purge gases as well as biogas produced in sewage treatment plants, solid waste dumps etc. Treatment of this air or gas means the removal of H2S. This technology solves also environmental problems: eliminates the sulfur compounds emission into the atmosphere.

The BIOSULFEX®PROCESS is also recommended in any places where a H2S contaminated air has been burned and now a FGD (flue gas desulphurization) installation is considered to meet environmental regulations.

BIOCAT®CATALYST

It is the most up to date process catalyst of conversion of H2S to Sel using a unique pulver concentrate BIOCAT®: non toxic, non degradable, easy for use and transportation, delivered in closed cans.

ZWHY THE BIOSULFEX® PROCESS IS TO BE RECOMMENDED

UP TO DATE

  • H2S removal efficiency > 99 %, few ppm on the outlet.
  • The compact construction of apparatus. Usually 20 times smaller in volume than conventional designs, do not require constant attendance, easy to maintain, made of high quality stainless steel.
  • Low biogas pressure loss within the installation < 20 mm H2O (2 mbars).
  • Solution patented in Poland and EU.

ENVIRONMENTALLY FRIENDLY

  • BIOSULFEX® produces no sewage.
  • BIOSULFEX® produces no off gases.
  • During BIOSULFEX® conversion of H2S to Sel as a by product, a small amount of sulphur powder suspended in water is produced. Sulphur powder has about 3% of impurities and may be used for different purposes.

COST SAVING

Cost of desulfurization: even less than 3€ per 1000m3 biogas.

PROVEN IN PRACTICE

Over 20 BIOSULFEX® installation in operation including some over 10 years. Capacity in range from 50 m3/h up to 2.250 m3/h. BIOSULFEX® was chosen by WTE Wassertechnik as “the best in class” technology for the biggest UE WWTP CZAJKA in Warsaw.

BIOSULFEX®

FOR DESULFURIZATION OF BIOGAS AND/OR OFF AIR

A leading technology for treating the biogas before gas engines, burners etc. Unique for its extremely low pressure drop. Optionally it can also remove dust and siloxanes from the gas.

MULTICAT®

FOR COMPLEX TREATING THE ASSOCIATED GAS TOGETHER WITH OIL

Best for small oil and gas wells. It is unique for its easy removing H2S from the crude oil before transportation.

BIOSULFEX®

FOR DESULFURIZATION OF NATURAL AND RAFINERY GAS

A technology for removing not only H2S but also mercaptanes, organic sulfides etc. Uses two catalytic solutions.
