How should low-temperature detectors be installed in the process unit areas and liquid guide channels of LNG receiving stations or plants?
Thread Content
I would like to ask the experts: According to GB51156 9.2.1,5, low-temperature detectors should be installed for leak detection in process unit areas, liquefied natural gas drainage ditches, and liquefied natural gas collection tanks. “\"Should\" means a mandatory requirement. But where should it be located? There is no specified range; if there is a channel for guiding liquid around the process equipment area, does installing a low-temperature detector in that channel suffice to meet this requirement? It seems unreasonable, but there are no regulations that specify exact numerical requirements, right?
One that should meet the requirements – we have one installed in the liquid collection tank of our LNG liquefaction plant. It is located right above the liquid collection tank, and the probe is very long
Everyone sets them in the collection tank, it seems that this is the practice throughout the industry. I would like to ask the students on the 2nd and 4th floors: if it is located at the inlet of the liquid collection tank, it can be placed at the inlet if there are drainage channels in the plant area. But in the liquid collection tanks in the tank area, there are no such drainage channels – so what do you do in that case? Is it okay by the pool? I would like to ask the students on the 3rd floor: have you set it right above the collection tank? How is it set up? Is it to place a rod above and tie the detector to it? It doesn’t seem very reasonable, does it?
