Deep Well Injection
Industry Served: Gas, Oil & Petrochemical
Problem:
Hydroplex HP-350 triplex plunger pump (0.75 gpm at 10,000 psi) for high pressure deep well methanol injection in an oil & gas upstream pumping application. On the discharge side of the pump, the amount of methanol the pump is dosing is metered. Without a dampener to control pulsations and smooth out the flow, the installed flow meters will not give accurate readings. Additionally, when using a triplex pump it is important that all three chambers of the pump stay full of fluid with no voids. Any voids or pockets can cause seals to leak, pump vibration and excess pump noise.
Solution:
A 12 cubic inch 10,000 psi SENTRY XPX model pulsation dampener was installed at the pump discharge to smooth out the flow and remove any pressure pulsations thus, allowing the dosing to be more accurate. An 85 cubic inch SENTRY inlet stabilizer (suction dampener) was installed on the inlet side of the pump to act as an accumulator to keep the pump chambers filled. The inlet stabilizer dampener also removes pulsations created by the pump on its inlet stroke.
Result:
