Standard system for removing H2S from biogas
Why use DMT Sulfurex®?
The Basic Process
• High H2S removal efficiency
Unique control system enabling
significant caustic saving.
A single stage, counter-current process (gas
scrubber) generates intense contact between
• Low caustic consumption
• Reliable and compact unit with small footprint
Selective desulphurisation is enabled through
the biogas and a circulating alkali liquid over
sensitive control of the gas speed, chemi-
a packing media. During this process, various
cal concentrations, pH values, temperature
chemical reactions take place ensuring H2S gas
and pressures at which the H2S and CO2 are
absorption by the alkali liquid. Ultimately the
processed. Adjusting differences in the physi-
H2S in the gas is almost entirely converted into
