摘要
根据焦耳一汤姆逊效应,在绝对节流过程中,液化石油气(LPG)气体会引起温降而产生冷凝液,因此,有必要计算和补偿预防其再液化所需的热功率。
According to Joule-Thomson effect,LPG's temperature could be decreased and the gas could change into condensed fluid under heat insulation flow regulating process,so it is necessary to calculate and compensate the calorific power to prevent LPG's reliquefaction.
