Daqing Petrochemical original condensate refining unit with precision filter, coke filter processing, the mixed bed process, the original design after oil and other impurities used in the equipment of the desalinated water, but because degreasing technology limitations, water quality to reach the necessary requirements (oil is less than / L), has not been applied, add water into the circulating water field as a circular. Therefore, the test by chemical condensate types of pollutants, ingredient concentration than the analysis, the choice of two prebarrier process and three intercept degreasing process and cover the filter and activated carbon filter treatment process of pilot test through continuous monitoring of various binations of process average effluent indicators to identify the treatment effect trend, results show that the bination of two prebarrier process and three intercept degreasing process technology more effectively to reduce the oil and ion content of the condensate, chemical condensation water after treatment, the effluent oil≤ / L, the removal rate of % of COD≤ mg / L, after a mixed bed, the water can reach the oil requirements of the boiler feed water standards and relatively low running costs, with considerable economic benefits and environmental benefits. The experiments show that the two prebarrier process and three intercept degreasing processes bined process chemical ethylene plant in the condensate has a better treatment effect.Key words:Condensate。 Oil removal 。 Conductivity removal;Interdiction degreasing東北石油大學(xué)工程碩士專業(yè)學(xué)位論文IV創(chuàng)新點(diǎn)摘要本文主要研究的是化工區(qū)乙烯裝置凝結(jié)水一種新型的處理工藝,其創(chuàng)新點(diǎn)如下:1.本文通過現(xiàn)場同步試驗(yàn),測定兩種不同工藝組合對(duì)化工區(qū)乙烯裝置凝結(jié)水處理的效果,并檢驗(yàn)了阻截除油工藝的運(yùn)行穩(wěn)定性和抗沖擊性,極具推廣應(yīng)用價(jià)值。2.利用兩級(jí)預(yù)屏障工藝和三級(jí)阻截除油工藝組合工藝,能夠?qū)⒒^(qū)乙烯裝置凝結(jié)水的出水油在 ,去除率達(dá) %左右, COD≤ mg/L,達(dá)到中石油規(guī)定的鍋爐給水標(biāo)準(zhǔn)驗(yàn)證了兩級(jí)預(yù)屏障工藝+三級(jí)阻截除油工藝+活性炭+ 混床組合工藝適用于化工區(qū)乙烯裝置凝結(jié)水處理。3.兩級(jí)預(yù)屏障工藝+三級(jí)阻截除油工藝+ 活性炭+混床組合工藝,在處理總鐵、油、電導(dǎo)等低濃度化工區(qū)乙烯裝置凝結(jié)水中,運(yùn)行成本低廉,性能穩(wěn)定。東北石油大學(xué)工程碩士專業(yè)學(xué)位論文目 錄學(xué)位論文獨(dú)創(chuàng)性聲明 .................................................................................................................I學(xué)位論文使用授權(quán)聲明 .............................................................................................................I摘 要 ......................................................................................................................................IIABSTRACT..............................................................................................................................III創(chuàng)新點(diǎn)摘要 ..............................................................................................................................IV前 言.......................................................................................................................................1第一章 文獻(xiàn)綜述.......................................................................................................................3 凝結(jié)水處理現(xiàn)狀 .........................................................................................................................3 凝結(jié)水處理的特點(diǎn) .....................................................................................................................3 凝結(jié)水除油除鐵技術(shù) ........................................................
