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. (more…)
