摘要
往复式氢气压缩机已广泛应用于石化行业的主要装置中,对其排气温度有限制,API618-95限制氢气含量较高的气体(相对分子质量≤12)预期的排气温度不超过135℃。但是,国内外的压缩机制造商有些只给出绝热排气温度,有些给出绝热和预期的排气温度。从分析气缸内,压缩机吸排气腔内以及吸排气阀通道内的热交换出发,得出缸内工作过程的热力学表达式,并分析了绝热、预期及实际排气温度之间的关系及影响因素。
Reciprocation hydrogen compressor has been widely used in petrochemical industry, but they have and limit on discharge temperature. As specified by API618, for hydrogen-rich gas(molecule weight≤12), the predicted discharge temperature shall not exceed 135 ℃. But, some compressor manufacturers only provide adiabatic discharge temperature, some provide adiabatic and predicted temperature. By means of studying heat transfer and the thermodynamics process for different stages inside cylinder, the thermodynamics No.1 law formulas for different stages have been obtained. Then demonstrating the difference between the adiabatic and predicted discharge temperatures and some key factors influencing discharge temperature.
