Description: Plan 76 is a containment seal chamber which allows venting of non‐condensing leakage from an Arrangement 2 dual seal, to a flare or vapor recovery system. Objective: Vent leakage to recovery while monitoring leak rate by sizing the orifice to allow maximum leakage. Pressure transmitter will shut down the pump if the leak rate […]
Description: Plan 75 is a containment seal chamber which allows draining of condensing leakage on Arrangement 2 dual seals. The collection system is located below the seal chamber and uses an orifice and a pressure transmitter to detect high vapor leak rates. Typically used with contacting secondary containment seals. Objective: Contain and vent leakage to […]
Description: Plan 74 is an external control system supplying BARRIER gas (typically Nitrogen) at greater pressure than the process pressure being sealed, to an Arrangement 3 dual gas seal. Objective: Prevent process from leaking to the atmosphere. Remove moisture, filter the gas and regulate the pressure to the seal. Best for hazardous, nonpolymerizing, non‐oxidizing fluids, […]
Description: Plan 72 is an external control system supplying a “whisper” of BUFFER gas (typically Nitrogen) at less pressure than the process pressure being sealed, to an Arrangement 2 dual gas seal, with a dry running containment seal. Used alone to dilute seal leakage or in conjunction with Plan 75 or 76 to help sweep […]

Plan 66A & Plan 66B
Description: Plan 66A is an external drain with an external pressure transmitter to detect high level leak rates. Normally for Arrangement 1 single seals. Pressure port and drain are separated by a gland bushing with an additional gland bushing on atmosphere side. Objective: Detect seal failure early and minimize leakage past gland. Typically used on […]
Description: Plan 65B is a TOTAL liquid leakage detection system measuring accumulated liquid leakage. Normally for Arrangement 1 single seals. Seal leakage will collect in a containment vessel with a level transmitter and bypass line to prevent pressure build up. This plan will require that the operator periodically drain the collection vessel to allow for […]
