for the effective cryogenic pump operation F.1 NPSH The e fficient operation o f the cryogenic pump is dependent on adequate NPSH The NPSH available (NPSHA) at the cryogenic pump inlet should be higher or equal to the NPSH required (NPSHR) by the pump, as specified by the pump manu facture An incompatibility in terms o f NPSH can cause cavitation and/or loss of prime Basically, the NPSHA consists o f the hydrostatic pressure o f the height di fference between the level o f liquid in the LNG storage tank and the height o f the pump inlet, reduced by dynamic pressure drop between the LNG storage tank and the pump inlet and reduced of increase of saturation pressure (boiling pressure) of liquid between the level of liquid in the LNG storage tank and the inlet of the pump considering stratification in the LNG storage tank and heat leak o f pipework The NPSHA can be improved by use o f a vertical LNG storage tank instead o f a horizontal LNG storage tank, by further elevating the foundation o f the LNG storage tank and/or by lowering the pump into a pit Also increasing the gas pressure above the cryogenic liquid sur face by pressure built up coil will raise the NPSHA F.2 Cavitation Cavitation is defined as the formation o f vapour cavities in a liquid by local pressure decrease below the fluid vapour pressure and the immediate implosion o f them, when the pressure increases again The cryogenic liquids are operated closely to their boiling point with very low sub cooling, which implies high risk of cavitation when design measures are not applied When the pressure at the inlet of the pump or in the pump drops below the vapour pressure, the liquid will vaporize resulting in biphasic state The mixture of liquid and gas can cause a pump to lose the prime and/or cavitation This condition will cause excess vibrations, noise and possibly dry running, which can cause damage F.3 Loss of prime The direct e ffects o f loss o f flow through the pump due to locking by vapour are dry running and possible excess vibrations, due to intermittent incoming liquid slugs, which can cause damage and leakage F.4 Pressure losses In the interconnecting piping between the LNG storage tank outlet and the suction o f the cryogenic pump, there are several pressure drops in the piping itsel f by friction, in elbows, in valves, in filters, etc These pressure losses reduce the cryogenic liquid pressure at the pump inlet to be closer to vapour pressure and thus reduce NPSH A This can cause cavitation and/or loss of prime F.5 Heat in leak As a cryogenic liquid is stored close to its boiling point, boiling can be caused by further warming Special considerations should be given to minimize leaking of heat between the LNG storage tank 66 I n tern ati o

or through a gearbox The pump sha ft protruding through the pump housing should be adequately sealed by a dynamic seal, to prevent or to minimize any gas leakages The following seals or sealing systems has proven to be adequate and accepted by the LNG industry: — simple mechanical seal; — gas bu ffered labyrinth seal; — gas bu ffered dry gas seal (DGS); — liquid buffered dual mechanical seal; — gas buffered dual DGS Some o f these seals are suitable only for vertical or only for horizontal sha ft sealing; some are suitable for both positions The sealing systems can include closed purged and vented lantern, according to the sealing system selected At the seal discharge, a temperature sensor is o ften installed to detect seal leakage in case of a seal failure Pump duty determines the selection o f the seal, the sealing system cost, the acceptance or nonacceptance o f any minor gas leakage and on the bu ffer gas and purging gas consumption and their availability The suitable sealing system evaluation should be per formed in conjunction with the pump manufacturer Additional in formation on centri fugal cryogenic pump design is given in the EIGA’s IGC Document 148/08 and in ISO 24490 H.2 Pump design with submerged motor The pump cold end is connected to the submerged motor in the motor housing; this is then connected to the pump housing Both housings together are built as statically sealed enclosures The motor stator insulation and the shaft supporting bearings should be designed for operation in LNG, which can include heavier hydrocarbons and impurities These conditions and the frequent start/stop operation will influence the bearings li fe time and will reduce the time between overhauls The pump rotor axial thrust has also major influence on the bearings li fe time These aspects should be reviewed with the pump manufacturer Alternatively, the pump housing with open suction mouth together with the motor in its housing may be installed in a suction barrel (slave tank) Such configuration is pre ferred for di fficult NPSH conditions, because at the barrel suction nozzle the NPSHR is usually zero However, alternative installations can
