近(jin)日，通过(guo)分析检测，己(ji)内酰胺(an)成(cheng)品(pin)(pin)(pin)各项数据均达(da)(da)到优(you)等(deng)(deng)品(pin)(pin)(pin)指标，尼龙(long)科技有限(xian)公司(si)二期(qi)暨(ji)升(sheng)级(ji)改造(zao)项目年(nian)产(chan)(chan)(chan)20万(wan)吨(dun)己(ji)内酰胺(an)成(cheng)套装(zhuang)(zhuang)置(zhi)正(zheng)式进入优(you)化工(gong)艺指标、调整(zheng)工(gong)艺参数、提高生(sheng)产(chan)(chan)(chan)负荷的试生(sheng)产(chan)(chan)(chan)阶段(duan)。这是继(ji)己(ji)内酰胺(an)二期(qi)暨(ji)升(sheng)级(ji)改造(zao)项目--36万(wan)吨(dun)/年(nian)发烟硫酸和年(nian)产(chan)(chan)(chan)15万(wan)吨(dun)环己(ji)酮低压装(zhuang)(zhuang)置(zhi)相(xiang)继(ji)投料试车成(cheng)功，产(chan)(chan)(chan)出优(you)等(deng)(deng)产(chan)(chan)(chan)品(pin)(pin)(pin)后，又一装(zhuang)(zhuang)置(zhi)产(chan)(chan)(chan)品(pin)(pin)(pin)投产(chan)(chan)(chan)成(cheng)功并达(da)(da)优(you)。
当前，年产(chan)(chan)20万吨的二期(qi)双氧(yang)水装(zhuang)置进入试生产(chan)(chan)阶(jie)段(duan)，高压环己酮装(zhuang)置进入投料试车(che)准备(bei)阶(jie)段(duan)。
预计8月(yue)初，中国平煤神(shen)马集团尼龙科技有限公(gong)司总(zong)投资21.15亿元的己内(nei)(nei)酰胺(an)二期项(xiang)目全线贯通，全面进入试生产(chan)阶段。该项(xiang)目2018年1月(yue)份开工建设，设计产(chan)能20万吨(dun)/年，投产(chan)后，尼龙科技公(gong)司己内(nei)(nei)酰胺(an)的产(chan)能规模由(you)10万吨(dun)/年提升至30万吨(dun)/年。
截至目前，20万吨/年己内酰胺二期项目包括配套装置，除高压环己酮在试车准备阶段外，其他各装置均一次投料试车成功。
尼龙科技公司20万吨/年己内酰胺二期项目和配套的15万吨/年环己酮项目，都位于河南省平顶山市“中国尼龙城”内，均为河南省、平顶山市两级重点建设工程。15万吨/年环己酮项目于2018年4月份开工建设，目前环己酮低压系统已经产出优等产品。高压装置预计8月初投料试车。
尼龙科技公司负责人介绍，10万吨/年己内酰胺一期项目，是依托国内单套产能最大、年产20万吨环己醇装置，利用环己醇脱氢、环己酮肟化生产己内酰胺。与一期项目不同，20万吨/年己内酰胺二期项目采用一期副产的环己烷作为原材料，形成新的链条生产己内酰胺。正在试车的(de)(de)15万吨(dun)/年环己(ji)酮(tong)项目(mu)是20万吨(dun)/年己(ji)内(nei)酰(xian)胺二期项目(mu)的(de)(de)配(pei)套(tao)项目(mu)，可以利(li)用(yong)一期生产过程中的(de)(de)副产品环己(ji)烷，进行工艺加工制作环己(ji)酮(tong)，为二期20万吨(dun)己(ji)内(nei)酰(xian)胺生产提(ti)供主原(yuan)料。这样(yang)既解(jie)决了副产品库存和销售压力、提(ti)升(sheng)综合附加值，降低(di)了成本(ben)，还避免了原(yuan)料的(de)(de)浪费，实现循环经济的(de)(de)发展模式。
