Description
Vapour leakages from inboard seal of dual containment seal are directed to a vapour recovery system via a vent connection.
Features
- Can be used with Plan 72 with buffer gas or with Plan 71 without buffer gas system.
- Vapour leakage collection ensures zero to very low process emissions from outboard containment seal.
Use
- For high vapour pressure fluids, light hydrocarbons.
- For hazardous or toxic media.
Caution
- Do not use for condensing media.
- Ensure continuous vent to low pressure vapour recovery or flare system.
- Tubing shall be 1/2” (13mm) minimum diameter and shall rise continuously from the CSV connection to the piping / instrumentation harness.
- A flow control orifice is required to generate back pressure.
- Ensure proper support to harness piping.
- Ensure a low point drain in the piping system.
