1results about How to "Reduce gasification" patented technology

The utility model relates to liquefied natural gas (LNG) long distance transportation and cold energy utilization technical field, concretely is a kind of LNG long distance transportation system based on composite heat insulation and dynamic cold preservation, LNG long distance transportation system equipment include: upstream LNG receiving station storage tank, LNG long distance transportation pipeline, downstream LNG receiving station storage tank, propane-liquid nitrogen exchanger, open rack type gasifier, LNG comes out from upstream receiving station storage tank, enters downstream receiving storage tank by long distance transportation pipeline, after propane-liquid nitrogen exchanger and open rack type gasifier temperature rising gasification again, enter natural gas pipe network, for downstream user use, the utility model utilizes propane-liquid nitrogen cold screen to carry out active intervention type heat preservation, block most of the heat entering inner tube, to reduce the gasification of LNG in inner tube, improve economic benefit.
