When should vent pipes be installed in LNG liquefaction plants, and when should flares be installed?
Thread Content
In actual projects, some LNG liquefaction plants are equipped with flares for their venting systems, while other plants use overall plant vent pipes. I would like to ask whether there are any mandatory requirements regarding this – when vent pipes should be installed and when flares are necessary – and whether there are any relevant standards or regulations governing this.
LNG liquefaction plants generally are equipped with flares.
Yes, but some are designed as exhaust pipes. Are there any mandatory regulations regarding this?
It is calculated based on the emission volume; if it is <120,000 cubic meters per day, an exhaust pipe can be installed； If it is greater, then the opposite is true
Is there any regulatory basis for this?
GB 50183-2004 Code for Fire Protection Design of Petroleum and Natural Gas Projects – relevant requirements are specified therein
There are fewer and fewer people who follow the rules, while more and more people rely on unreasonable arguments. The torch is gone; dispersion has occurred
