Safety Measures for flammable Propylene Oxide pipeline overground
Safety Measures for flammable Propylene Oxide pipeline overground
(OP)
Dear Professionals
We are working on the project of 4km-longed Propylene Oxide pipe line in Jurong Island, Singapore. Local code of practice for design, construction & operation of flammable liquid pipe line allow no pressure relief device, no low point drain and high point vent along the pipeline service corridor.
ASME B31.3 also calls for grounding and bonding of overground flammable liquid piping in order to prevent static electricity.
Could you guys please advice me what type of safety measures should be taken in case of exceeding design pressure along the pipeline between the supplier and plant battery limit?
I can't think of more than double block and bleed tight shut-off (TSO)actuated valves at plant battery limit.
Also, what type of grounding and bonding for Propylene Oxide pipeline?
Your professional advices are highly appreciated
Best Regards

I know of this job and the designer has been shopping around for someone to do the surge analysis and heat transfer design. I get the opinion that a competent experinced design house needs to be engaged. It is very risky someone designing such a pipeline and asking such basic questions.
Remind me to stay away from Singapore for a while!

we used this all the time for ethylene, propylene, benzene and other lines.
