Regarding the issue of sealing and recovering condensate in combustible gas vent pipes
Thread Content
Under the safety inspection requirements, in accordance with Article 5.5.17 of the Code for Fire Protection Design of Petrochemical Enterprises (GB 50160-2008), the condensate in the flammable gas vent pipes shall be recovered in a sealed manner. The main flammable gases in our facility include hydrogen and acetylene, among others, and they are transported over long distances, making it difficult to achieve unified, sealed recovery. Dear sea friends, do you have any good ideas or suggestions? What kind of recovery devices can be used to achieve sealed recovery, and how should the recovered condensate be handled?
Add a liquid cutting tank and use a pump to apply pressure for recovery
If the quantity remains stable, one could consider building a boiler to generate steam and so on, for energy conversion – turning waste into something useful!
Add collection tanks; install pipes at all low points for sealed recovery; pressure difference can be considered as a driving force
Several condensate tanks should be installed along the way to increase the amount of light polluted oil that can be pumped into the light polluted oil pipeline
A oil separation tank is generally installed before the vent pipe leads to the flare, with the purpose of collecting the condensed liquids within the vent pipe. The drain pipe of this separation tank is equipped with a liquid seal.
Adding a drain at the lowest point allows for the use of a liquid trap there, with regular drainage; in addition, heat tracing can be considered to prevent the formation of condensate
With my limited knowledge, may I ask: who has ever seen the condensate of hydrogen gas or acetylene gas? :In fuel pipelines dominated by methane hydrogen, the liquid, viscous oligomers can be discharged at the lowest points of the pipeline network.
