Full Scale Biological Removal of Hydrogen Sulphide from Gas

Andre L. de Vegt, Paques Inc., 486 Thomas Jones Way, Suite 100, Exton, PA
19341 USA.

Cees J.N. Buisman, Paques B.V. P.O. Box 52, 8560 AB Balk, the Netherlands.

Over the past eight years Paques has been developing biological treatment
methods to solve environmental problems related to sulphur compounds. One of
the developed bioprocess technologies can be used to remove hydrogen
sulphide from air and gas streams. In a scrubber/bioreactor combination,
hydrogen sulphide is converted to elemental sulphur by sulphide oxidizing
bacteria. A full scale plant treating 450 m3/h of biogas containing 12,500
ppm of H2S has been in operation for over two years. The results are very
encouraging:

1.High removal efficiencies (99%+) are realized

2.More than 90% caustic reduction compared to conventional caustic
scrubbers, resulting in very low operational costs.

The produced sulphur slurry consists of 99% sulphur and can be easily
upgraded using a sulphur smelter. In the paper the principle of the
biotechnological method will be explained and full scale results will be
presented
