摘要
针对再冷凝器在运行中出现的液位波动，以及高压泵放空量对再冷凝器液位的影响，通过对再冷凝器结构的计算分析，得到再冷凝器液位控制在55％以上有助于再冷凝器的稳定运行；通过质量守恒定律和能量守恒定律计算得到单台高压泵运行时的BOG放空量约为2t／h，这部分BOG再冷凝所需的LNG约为1．2t／h，对再冷凝器液位的影响约为8．8％，实际操作中可以根据高压泵运行情况适当增大参与再冷凝LNG的量，保证再冷凝器内的气液平衡，从而保证再冷凝器的稳定运行。（图2，表2，参6）
In allusion to the LNG level fluctuation in the operation of recondenser and the impact of HP pumps＇ venting volume on the level of recondenser, it has been found that maintain the LNG level at 55% above of the recondenser height is conductive to stable operations by computational analyzing the structure of the recondenser. According to the law of conservation of mass and energy, it obtains the result of the BOG venting volume is about 2 tons per hour during the operation of single HP pump. This portion of BOG needs 1.2 tons LNG per hour for recondensation and its impact on the level of recondenser is about 8.8%. The amount of LNG involve in the recondensation can be increased reasonably according to the running condition of HP pumps in actual operation, in order to ensure the gas-liquid equilibrium in the recondenser and thereby ensuring stable operation of recondensation. （2 Figure, 2 Tables, 6 References）.
