增压站天然气发动机余热利用方案研究

Research on the Use of Waste Heat at the Natural Gas Booster Station

压缩机增压站安装防噪声工房后房内温度超标,影响机组的正常运行;油气田地面站场燃气发动机组的热能有效利用率仅有40%左右,而发动机组的高温烟气通常被白白排放。提出的天然气发动机烟气余热回收利用方案结合现代吸收式制冷技术,可以解决增压站的防噪声工房、中控室、办公楼等地的夏季降温、冬季保温问题,并可实现制冷量与防噪声工房内发动机空压机组散热量的动态平衡,满足机组在防噪声门关闭情况下的温度要求环境,可有效提高系统的能源综合利用率,实现节能减排。

After the noise against house at the station of compressor booster installed, it causing the ultra-high temperature has affected the normal operation. The high-temperature gas from the group of engine was often released unfortunately, but in the oil and gas fields, the ground station of the gas engine was only about 40 % in its utilization of the heat energy effectively. The technique to recovery the natural gas engine waste heat was presented and combined with the development of the modern absorption refrigeration technology to make use of cooling in summer and heating in winter in the places like the noise-against house at booster station, the control room, the office buildings and so on. It can also achieve the dynamic balance between the cooling capacity and the heat dissipation of compressor in the noise-against house, which can meet the environment of the engine and the compressor worked for under the conditions of the noise-against house＇s door closed. It can improve the system of comprehensive utilization effectively, to enhance the economic system and to achieve energy reduction.
