Should the fire protection codes for LNG plants be based on 50183 or 50160? Is it necessary to install an accident wastewater tank?
Thread Content
The liquefaction station is equipped with LNG storage tanks and condensate oil storage tanks. Experts recommend the installation of an accident wastewater tank; the requirements for such a tank are those specified in 50160, which are stricter than those in 50183. Is it necessary to follow the standards set out in 50160?
Expert advice is one thing; whether you follow it or not is a decision for your own company – the company has its own autonomy. If an accident occurs and there is no place for the fire-fighting water to go, resulting in a secondary accident, that will be your organization’s problem ； In the case of a serious secondary accident, it may be necessary for someone to go to the prosecutor’s office to explain the situation. If it was your idea and decision to eliminate the accident pool, then of course you will need to go to the prosecutor’s office together with the legal representative.
Even without an accident wastewater tank, safety issues still exist...
In accordance with Document No. 376 issued by the Chief Safety Supervisor, it should be designed based on standard 50160. However, liquefied hydrocarbons in 50160 do not include liquefied natural gas: L
The new \"Design Code for Natural Gas Liquefaction Plants\" (GB51261-2019) has been released and will come into effect on December 1, 2019.
The statement that the new 50160 LNG does not belong to liquefied hydrocarbons has been removed: lol. The design standards for natural gas liquefaction plants clearly state that LNG is considered a liquefied hydrocarbon
I’d like to ask a question: Since LNG is a type of liquefied hydrocarbon, does it fall under the regulations regarding the minimum material grade required for pipelines used to transport different types of media? Specifically, the regulation states that pipelines used to transport liquefied hydrocarbons must have a strength rating of 2.5 MPa. ”
This issue isn’t very clear. I work on overall layout design, and what you’re dealing with falls within the scope of pressure pipelines. In my opinion, it’s possible to follow the guidelines for liquefied hydrocarbons or refer to the provisions in GB51261.
It is necessary to design the accident tank in accordance with 50160; refer to the reference book on industrial pipeline design, which provides relevant information
