我厂40万吨/年大加氢装置引进的美国Elliott 公司生产的25MBH9型循环氢离心压缩机,该机由汽轮机驱动(额定功率为1345千瓦,10820转/分,耗汽量22.5公斤/千瓦·时,蒸汽压力35公斤/厘米~2)。为了确切了解该机的技术性能,以便在多种工艺条件下,选择最佳操作方案,我厂对该机进行了性能测算。本文将测定和计算的有关数据分析、阐述于后。一、压缩机的参数输送气体:轻油制氢,水洗氢;流量 V:10~5标米~3/时;进气压力 P_λ:176公斤/厘米~2(绝);进气温度 T_λ:313°K;排气压力 P 排;211公斤/厘米~2(绝);转速 n:7000～11360转/分。二、压缩机的特性分析1.多变效率η_(poe)(1)排出压力(在进气压力176公斤/厘
I plant 40 tons / year of large hydrogenation unit introduced by the United States Elliott’s 25MBH9 circulating hydrogen centrifugal compressor, the turbine driven by the aircraft (rated power of 1345 kilowatts, 10820 rev / min, consumption of steam 22.5 kg / kW ·, Steam pressure 35 kg / cm ~ 2). In order to understand exactly the technical performance of the aircraft, so that in a variety of process conditions, choose the best operating program, I plant the performance of the aircraft. This article will measure and calculate the relevant data analysis, described in later. First, the parameters of the compressor Conveyor gas: light oil hydrogen, washed hydrogen; flow V: 10 ~ 5 standard meters ~ 3 / hour; intake pressure P_λ: 176 kg / cm ~ 2 (absolutely); intake air temperature T_λ: 313 ° K; exhaust pressure P row; 211 kg / cm ~ 2 (absolutely); speed n: 7000 ~ 11360 rev / min. Second, the compressor characteristics analysis 1. Variable efficiency η_ (poe) (1) discharge pressure (at intake pressure 176 kg / PCT
