摘要:在责州某公司以半水煤气合成工艺的运行维护中,压縮机級间换热器结焦是一个最为突出、急需解决的
河题。结焦造成换热效率下降,阻力増加,压缩比降低,严重影响生产的正常运行。本文以责州某公司合成压
缩工段换热器结焦为研究对象,根据前期对结焦机理及结焦物化学组分的研究,采用超声清洗方法,选取OP-10
十二炕基碱酸钠作为主剂,氢氧化钠作为碱性助剂,研究对比各试剂的清焦能カ,并对其进行复配,考察清洗剂
的纽成、浓度以及清洗温度对焦垢去除能力的影响。结果表明:OP-10乳化剂最佳浓度为60g1.,十二烷基磺酸钠
的最佳浓度为50g1,氢氧化钠的最佳浓度为3g/;且当浓度为60g1.的O)P-10乳化剂、50g1.的十二烷基磺晙
钠和3gL的氩氧化钠复配组成体积比为1:2:2的清洗剂,在50℃时对焦垢进行超声清洗的清洗效罘最好。

Abstract: In the operation and maintenance of ammonia synthesis process with semi-water gas, coking
problcm of a Guizhou companys compressor hcat cxchangcr is onc of lhc most prominent and urgent
problem. Coking not only caused the heat transfer efficiency decrease, increased the resistance, reduced
compression ratio, but also seriously affected the normal operation of production. This paper aimed at
the comprcssion scction of synthctic ammonia coking phcnomcnon of a Guizhou company. Bascd on
coking mechanism and composition, ultrasonic cleaning method was used. OP-10, sodium dodecyl
sulfate were selected as leaning agent Sodium hydroxide was selected as co-cleaning agent. Oplimum
composition and concentration of ultrasonic cleaning agent, cleaning temperature and cleaning ability
werc studicd. Expcrimcntal rcsults showcd that the composition of thc clcanin agent is 60/L OP-10
cmulsilicr, 0 L sodium dodecyl sulfonate, 3 /L sodium hydroxide with thc volume ratio of 1: 2
When the ultrasonic cleaning was performed at 50 C, the cleaning result was the best
