摘要/Abstract

摘要： 研究了环戊烷-甲烷水合物生成过程中的温度变化,分析了体系的热量损失。在不同初始温度(4℃、8℃和12℃)、压力(2MPa、4MPa、6MPa、8MPa和10MPa)和进气方式(一次性进气、连续进气和间歇进气)的条件下,测定了釜内温度,对比了以上各因素对釜内最高温度(T_max)与釜内最大温升(ΔT_max)的影响。实验表明,T_max主要受压力和进气方式影响,初始温度对其影响不明显;ΔT_max受初始温度、压力和进气方式影响显著。在间歇进气方式下,初始温度越低、压力越高,ΔT_max越大。其中,在初始温度为4℃、压力为10MPa、进气时间间隔为30min的间歇进气方式下,ΔT_max可达16.5℃。此外,由热量分析发现,体系的主要热量损耗表现为体系向环境中的散热。因此,提高保温层的绝热性能,有利于提高水合物生成热的热量有效利用率。

Abstract: In this paper, the changes of the system temperatures and heat loss were investigated during the formation of cyclopentane-methane binary hydrates. The system temperature measurements were carried out under the conditions of initial temperatures of 4℃, 8℃, and12℃, pressures of 2MPa, 4MPa, 6MPa, 8MPa and 10MPa, and different gas injection modes (single, continuous and intermittent). The maximum temperature (T_max) and the maximum temperature increase (ΔT_max) in the system were compared. The experimental results illustrate that the pressures and gas injection modes have significant influence on T_max while the initial temperatures, pressures and gas injection modes all significantly effect ΔT_max. Thus, the conditions of lower initial temperature, higher pressure and injecting intermittently help to increase ΔT_max. Under the condition of 4℃ and 10MPa, intermittent injection with the interval time of 30minute, the maximum value of ΔT_max is 16.5℃. In addition, the heat analysis results indicate that the main heat loss is from the inner reactor to the outside cold environment. Therefore, improving the insulation properties of insulating layer is helpful to enhance the heating efficiency in the process of the cyclopentane-methane binary hydrates formation.
