Improvements in or relating to the retention of composition of liquefied natural gas on vapourisation

摘要

A method of vapourising a sample of liquefied natural gas so as to retain the proportions 5 of components of the liquefied natural gas on vapourisation, the method comprising the steps of: introducing liquefied natural gas into a liquid inlet. 112 of a liquefied natural gas vapouriser 110; vapourising the liquefied natural gas at a vapourisation element 134 of the liquid inlet 112; and directing vapourised liquefied natural gas into a vapourisation conduit portion 120 directly after the liquid inlet, the vapourisation 10 conduit portion 120 having a fall, thereby encouraging vapourised liquid natural gas to be directed against a flow direction of liquid or liquid-gas phase natural gas in the vapourisation conduit portion to encourage remixing of the vapourised liquid natural gas and liquid or liquid-gas phase natural gas A liquefied natural gas vapouriser 110 suitable for the above method is also provided.
