Abstract:The research and development of LNG coil-wound heat exchanger (LCWHE) were discussed in view of the heat exchange in LNG field in petrochemical industry. The basic designing methods and the multi-stream heat exchange processes were illustrated by the cryogenic and high pressure crossing heat exchange equipments of LCWHE with multi-stream and multiphase flow, including Four-stream LCWHE in first stage, Three-stream LCWHE in second stage, Two-stream LCWHE in third stage, Multi-stream main LCWHE etc. A series of LCWHE with different mixed refrigerant and different applications were described. The winding structure characteristics and the working principle of the spiral pipe bundles were elaborated to give a reference for the scientific design and calculation of LCWHE in cryogenic field. The major researched directions and the critical scientific problems were forecasted.
