Abstract:
It is widely accepted that valve stem leakage accounts for the majority of fugitive emissions from petrochemical and chemical sites often accounting
for over 50% of fugitive emissions from these sites. The most common valve sealing device is the compression packing and even though compression packings
have been used for over 150 years, there is still a considerable lack of knowledge into how they effect a seal in a valve. This project hopes to bridge this gap by gaining a greater scicntific understanding of their behaviour in order to implement improvements in compression packing installation and operation.
