Low lift Dry Gas Seals in high vapor pressure, flashing hydrocarbon pump applications - (PPT)

摘要

Pump and seal duty points (shaft power, suction vapour margin, seal p.v.) are too high to permit creation of an appropriate degree of seal chamber vapour margin for a 'wet' primary seal. Cooling process to seal to increase vapour margin is not viable; process temperature, CAPEX required, time, etc..
