Direct catalytic oxidation of H2S into elemental sulfur


 

The technology provides effective treatment of gases both with high (5-95 vol %) and with low (0.01-5 vol %) hydrogen sulfide content.

The compact-size units can be erected directly on sites of extraction and primary processing of oil and gas.

 
Тwo versions of the technology are available.
Gases with 5-95 % vol of hydrogen sulfide Gases with 0.01-5 % vol of hydrogen sulfide
OBJECTS:OBJECTS:
“acid” gases,associated oil and natural gases,associated oil and natural gases,
hydrotreatment gases, Klaus tail gases
natural gases, etc. geothermal steam, biogas, etc.
The process is achieved in a fluidized catalyst bed reactor. The process is achieved in a fixed catalyst bed reactor; honeycomb catalysts also can be used
 
Operation parameters of the fluidized catalyst bed reactor
“Acid” gas capacity, m3/h up to 300
Sulfur yield, kg/h up to 200
Volume ratio of hydrogen sulfide in the inlet gas, % 60
Purification degree, % 97
Loaded catalyst, kg 100
Plant payback period, year 0.5-1.5
 
Advantages
(compared to the Klaus process)
Reduction in capital cost down to 1/3 – 1/4
Reduction in operation cost down to 1/4 –1/5
Reduction (may be 100-fold) in expenses of waste and utilization of toxic effluents
High purity grade of target products (sulfur, fuel gas)
 
State-of-the-art
The technology are used at Russian refineries and oil deposits.
