摘要: 移动式LNG应急装置供气范围广,设备利用率高,基本满足各类用户的应急供气需求。但现有空温式LNG应急装置供气稳定性仍不足,明火水浴式LNG应急装置气化成本偏高,本文提出了一种新型的移动储热式LNG应急装置;并对其进行了原理介绍、概念设计和技术经济性评价。结果表明,大中型移动储热式LNG应急装置的应急供气成本与空温式相当,分别为2.23元/Nm3和2.42元/Nm3,比明火水浴式节约;气化强度可达70Nm3/(m2·h),与水浴式相当;其具备实际可操作性及经济可行性。

Abstract: The use of mobile lng emergency units (MLEU) is an effective method to meet urgent gas supply demand. Current MLEU using ambient air vaporizer (MLEU-AAV) and gas fired water bath vaporizer (MLEU-GFWB) have a poor stability, and the MLEU-GFWB is expensive. This paper introduces a novel mobile LNG emergency unit with a heat storage vaporizer (MLEU-HSV). The working principle, conceptual design and techno-economic evaluation of the MLEU-HSV are outlined. The results show that the specific emergency gasification cost for large and medium-sized MLEU-HSV is comparable to MLEU-AAV, 2.23 yuan/Nm3 and 2.42 yuan/Nm3, respectively. They are about 0.1 yuan/Nm3 lower than that of MLEU-GFWB. The gasification intensity can reach 70 Nm3/(m2·h), comparable to that of MLEU-GFWB. These results suggest that MLEU-HSV be a promising alternative to the current technologies.
