Abstract : this paper introduces the operation of light hydrocarbon xecoveryunit under low capacity eonditions , the approaches to improve propane recovery while the products quality are ensured 文摘:介绍渤西油气处理厂轻烃回收装置低负荷运行状态下,提高丙烷收率的措施及方法。
The purpose of this study is to investigate the effect of heat recovery system by redirecting the exhaust air through a mechanism device in a hot air dryer 试验结果显示热能回收装置可将进气温度从大气温度(约32 )提升到42 ,以温度为基准的效能评估,研制的的热能回收效能可达65 %以上。
These analyses indicate that the periods of time for equipment investment reclaim are from 5 to 15 months , which shows their economic benefit efficiency and energy conservation efficiency are remarkable 分析表明,所设计的余热回收装置的投资回收期在5 15个月,经济效益和节能效果十分显著。
There are three kinds of drying systems : hot air drying , dehumidifying drying , and natural drying ; however , hot air drying is the most popular drying system 本研究的目的为探讨热能回收技术的效能,在热风干燥系统中设计和研制排放湿热气和进入空气接触的热能回收装置,达到加热进气温度,减少干燥作业所需能源。
