Hydrogen Sulphide Knock Out Pots
Iron filings are used to develop ferrous oxide that converts
H2S into iron sulphide. H2S is an asphyxiant and corrosive gas
which causes damage particularly to moving parts and yellow
metals. The filings are replaced on a maintenance schedule and
exported from site for controlled disposal.
2. Low Pressure Compression
The gas is compressed in a 16 bar trunk piston compressor
with a 200 litre receiver tank and aftercooler. Water released
from the gas is drained and re-circulated to landfill or treated
as leachate
3. Water Cooler
An aftercooler circulates water through a jacket around a
section of the pipework to reduce the gas temperature. The
cooling of the gas releases water vapour which is collected
in a condensate tank and can be re-circulated to landfill
or treated as leachate.
4. Filters
3 Micron filters in series separate oil vapour resulting from
the compression stage. Two water filters are also attached
to further remove any further water vapour. The waste produced
from this stage is oil and water droplets which can be re-circulated
to landfill or treated as leachate.
5. Activated carbon Towers
The activated carbon adsorbs the trace contaminants The large
surface area of the carbon granules allows a large quantity
of contaminant removal. The contaminated carbon is periodically
replaced and is exported from site for controlled disposal
or can be heat regenerated.
