I would like to ask about the calculations involved in selecting equipment for LNG gasification stations
Thread Content
May I ask how to determine the size of the unloading booster, tank booster, vaporizer, and BOG/EAG heaters in an LNG vaporization station? How is this calculated? I would appreciate it if specific calculation steps or relevant information could be provided. Thank you! Additionally, does 300 m3/h refer to a gaseous flow rate or a liquid flow rate?
Judging from your flow rate, it should be gaseous; if it were liquid, the volume would be larger.
The amount of gas is determined by multiplying the amount of gas that can be vaporized per meter of fins by the total length in meters of fins.
Has the original poster resolved the issue? If possible, please share the relevant materials via email. Thank you, fyw694@163.com

The capacity of the main vaporizer is determined based on the designed gas consumption; for unloading and tank pressurization, a capacity of 300 or 500 cubic meters is usually chosen, while for BOG, 500 cubic meters is also typically selected. For EAG, the capacity is generally 150 or 200 cubic meters. Of course, it is necessary to take into account the overall scale of the facility (i.e., the gas consumption). As for the calculation of the vaporizer, it is generally done based on empirical values. The general gas consumption is expressed in standard cubic meters, such as: 300 Nm3/h.
Isn’t there any formula software or something for detailed calculations? Is everything chosen roughly based on engineering experience?
Same question. Go up there. I don’t know how to calculate it at all.
We just signed the contract and installed a new gasification station; we don’t quite understand it yet……
According to recent research*, it has been found that for EAG heaters, the selection can be determined based on standard GB150 B.7.4 regarding the safe venting capacity of containers holding liquefied gases: when there is a complete insulation layer, the safe venting capacity is calculated using Equation 1. I haven’t studied the rest yet; those who are interested can take a look.
