Hello All,

 

I want your help regarding installation of double block and bleed valve in acid gas line.

 

We got internal recommendation to install DBB on amine acid gas & sour water acid gas lines, routed from amine treatment and sour water treatment units to sulfur recovery unit.

 

 

Kindly inform if any related standard, article or book where explained/discussed installation of double block and bleed valve on acid gas/sour gas line.

 

 

Thanks,

Azhar
