Recommendations for Acid Gas Service
Ariel offers application specific components, engineered to ensure the performance, safety, and reliability of your acid gas operation. Our recommendations for sour gas service are based upon field experience and NACE guidelines – providing innovative, safe solutions to minimize equipment corrosion often associated with CO2 and H2S contact.
Distance Piece + Crosshead Guide
Ariel recommends two compartment guides for sour gas service. These short and long two compartment guides offer a purge and vent system – designed to separate the frame compartment and operator atmosphere from the packing leakage and blow by, keeping the sour gas from entering the crankcase.
*Two compartment guides are not available for the JGM: N: P: Q frames.
Piston Rod Material
Ariel offers 17-4PH stainless steel piston rods, chromium-nitrided in the packing travel area for acid gas service with high CO₂ and H₂S content. These heavy duty piston rods reduce the potential for corrosion.
Purge Packing
For proper venting, Ariel recommends the use of purge packing for services with high acidic gas components. Ariel’s purge packing blocks and directs hazardous, toxic, flammable, or corrosive gases – preventing exposure to personnel and eliminating damage to the running gear.
Flushing Lube
Ariel offers cylinder flushing lube for sour gas services with 100 ppm and greater H₂S content, supplying additional distribution blocks so that oil can be injected into the suction nozzle riser of the cylinder.
17-4PH Stainless Steel Valves
17-4PH stainless steel valves are recommended for sour gas services with 2% and greater H2S content.
