Abstract:
A compressor for compressing hydrogen sulfide in which the gas being handled is at a total pressure of 65 psia (448 kPa) or greater and the partial pressure of hydrogen sulfide in the gas is greater than 0.05 psia (0.34 kpa), the compressor comprising:a housing;a first impeller arranged in said housing and for compressing the hydrogen sulfide, said first impeller having a parameter causing said first impeller to operate below a total pressure of 65 psia (448 kPa) for the gas being handled by said compressor or a partial pressure of hydrogen sulfide in the gas is less than 0.05 psia (0.34 kPa), during operation of the compressor;a second impeller arranged in said housing and for further compressing the hydrogen sulfide from said first impeller, said second impeller being formed to operate at a total pressure of 65 psia (448 kPa) or greater for the gas being handled by said compressor and at a partial pressure of hydrogen sulfide in the gas is greater than 0.05 psia (0.34 kPa), during operation of the compressor.
