LNG Recirculation Requirement

In LNG receiving terminal, where LNG is pumped from LNG carrier to onshore LNG storage tank, we have to provide one line to intermittently circulate LNG through unloading lines. This is called LNG recirculation line or keep-cool line.  The function of this line is maintain cryogenic condition of the unloading line during holding mode. Unloading activity is conducting intermittently. Sometimes we need to wait for a week or even a month to the next LNG unloading. During this time, there is a possibility of increasing temperature in the line. To prevent that, we need to circulate LNG in unloading line. Read More

Typical Process Diagram for Small LNG Regasification (Part 2)

As mentioned in part 1, small LNG regasification facility typically consists of LNG unloading facility (which can be flexible hose or marine loading arm), LNG storage tank, LNG sendout pump, ambient air vaporizer, and metering. In part 1 we already discussed about LNG unloading facility and LNG storage tank. In this part I want to share the rest of them.

LNG Sendout Pump

LNG sendout pump is used to increase pressure of LNG before being sent to vaporizer. In LNG facility, there are two most common type of pump: submerged centrifugal pump and reciprocating pump.

Submerged centrifugal pump is used when LNG flowrate is high but the pressure in low to medium. Meanwhile reciprocating pump is used when the flow is low but the pressure is high. Read More

Typical Process Diagram for Small LNG Regasification (Part 1)

Today I want to share you Typical Process Diagram for Small LNG Regasification. For your information, small LNG regasification is very useful to be built in remote location where power supply is very limited.
