About this document

Preventing PSV Chattering Risks by Mohamed Achour is a document available to read on EtoBox.

A gas release incident occurred at a Vinyl Chloride plant when a line blockage led to the release of toxic gas through a Pressure Safety Valve (PSV) at high pressure. Vibrations caused the PSV flange bolts to loosen, resulting in a significant gas leak. Recommendations include minimizing PSV chattering and using valves with threaded retainer rings to prevent carbon deposits that can block valve operation.
