摘要

针对陆上LNG加气站和LNG运输槽车的BOG放散所造成的燃料损失和环境污染等问题

以大功率脉管制冷机为冷源研发了一套小型撬装式BOG再液化装置。在LNG加气站对该小型撬装式BOG再液化装置进行了试运行实验

装置具有较好的稳定性、可靠性和安全性。实验结果表明:装置的净制冷功率至少达到550 W@120 K

BOG的液化能力达到106 kg·d-1。

Abstract

Mainly for the problems such as fuel waste and environmental pollution resulted from BOG release of LNG filling stations and LNG tank vehicles

a small scale BOG re-liquefaction equipment in skid-mounted package has been designed and produced based on a high power PTC(Pulse Tube Cryocooler).Field experimental tests have been conducted to the small scale BOG re-liquefaction equipment

it is proved that the equipment can work with good stability

reliability and safety.It is showed from the experimental results that the net cooling capacity of the equipment is at least 550 W@120 K and its BOG re-liquefaction ability is as high as 106 kg·d-1.
