we Use ADIP 18% strength to remove H2S and COS from Propane and H2S and CO2 from Fuel Gas - used for molecular sieve dehydration.We have two altrenatives for fuel gas. One is completely sweet and other with 1% CO2 content.
when Fuel gas that contains <5ppm H2S and approx 1% CO2 is used, ADIP regeneration is effective.
when sweet fuel gas is used, ( without CO2) , adip regeneration is almost NIL
Lab Results when Sweet Fuel gas is used:
Rich ADIP: H2S: 480 PPMwt CO2: 251 PPMwt.
Lean ADIP: H2S: 456 PPMwt CO2:78 PPMwt.
Lab results when Fuel gas with 1% CO2 is used:
Rich Adip: H2S: 1205 PPMwt CO2: 2241 PPMwt
Lean Adip: H2S: 154 ppm wt CO2: 730 ppm wt
Cause of Ineffective Adip regeneration to be reasoned.
