Treatment
of Odor pollution from petrochemical SDP
Odor
pollution from refinery SDP is one of the focuses of
refinery personnel, habitants near refinery and the
environmental protection departments. The odor pollutants
released by SDP are ammonia, hydrogen sulfide, organic
sulfide, volatile hydrocarbons and etc. These substances
have low odor threshold and cause great harm to people’s
health. Their discharging is strictly limited according to
GB 14554-93 (Discharging standard for odor pollutants)
and GB16297-1996.
FRIPP has been engaged in the study and treatment of
odor pollution. It has cooperated with several companies
and successively carried out Pilot scale catalytic
combustion test for odorous gases from oil separator under
40000h－1
and temperature 250℃.
The removal of total hydrocarbon can be over 97% and the
purified gases meet the GB16297-1996 and with no
unpleasant odor. Pilot scale activated carbon adsorption
test for odorous gases from surface aeration pool under
LHSV 1500h－1(desulfurizing
bed) for 100 days. The removal of the major pollutant,
methyl mercaptan remained at 98%～100%.
Under on-site conditions, the maximal sulfur containing
capacity can be 2%～3%（W）.
Bench scale bio-packing column sweetening test for
odorous gases from blow aeration pool. Over 80% of benzene
series compounds and organic sulfur compounds and over 98%
hydrogen sulfide can be removed.
At
present, a commercial catalytic combustion test for
odorous gases from oil separator is being carried out in a
refinery and a pilot scale bio-sweetening test for
treating odorous gases from aeration pool is also under
way.
