Refinery processes involving light hydrocarbons and high vapor pressure fluids present challenges in ensuring that that they remain safely contained within the systems, piping, and pumps involved in the process …

Many pumping processes in refineries circulate high-temperature, heavy hydrocarbons. The mechanical seals in many of these pumps often require a seal support quench system to prevent coking—which occurs when hydrocarbon …

Pumping processes involving toxic or hazardous fluids that can’t risk leakage because of stringent environmental regulations require a double mechanical seal. Compared to a single mechanical seal, a double seal …
