Problem Analysis and Optimization Study on Cold Energy Utilization Device of LNG Fishing Vessels
摘要
Abstract
The phenomena of long cold storage time of cold energy utilization device on LNG fishing vessel and solidification of cold storage agent in LNG-cold storage agent heat exchanger are analyzed and studied.The causes of the problems are found:the temperature measurement position of the cold storage a-gent storage tank is not good,the heat exchange effect of LNG-cold storage agent heat exchanger is not good or the freezing point of the cold storage agent is high.The experiment found that the freezing point of the cold storage agent meets the process requirements,there-fore,the temperature measurement position of the cold storage agent storage tank and the equipment form of the LNG vaporizer are improved.Based on the spiral coil vaporizer in the original process,one combined in-termediate medium vaporizer is connected in parallel,and two vaporizers are switched for use.The improve-ment measures have solved the above problems well.关键词
