Many U.S. oil refineries use large volumes of highly concentrated hydrofluoric (HF) acid as chemical catalysts in a process called alkylation which creates additives that boost the octane of gasoline.…
A mechanical seal will run at its most stable condition when there is a sufficient pressure margin in the seal chamber over the process liquid’s vapor pressure at local temperature.…
When dual pressurized seal applications exceed an API 682 Plan 53’s normal operating conditions for flow, pressure, and temperature, an API 682 Plan 54 seal support system is required. Equipped…
The benefits of reducing fluid temperatures in pump-seal operation include reduced vapor pressures, increased fluid viscosity, and a reduction of generated heat at the seal faces. There are two ways…
The mating pair of counter-rotating seal rings are the heart of the mechanical seal and designers must consider many overlapping physical systems affecting their performance. Sealing systems are complex, and…
