中鹽吉蘭泰鹽化(hua)集團１００萬噸(dun)／年(nian)聚(ju)氯乙烯項目(mu)是國(guo)內(nei)目(mu)前(qian)最大(da)的電石法生產(chan)聚(ju)氯乙烯項目(mu)，吸收了國(guo)際先進的氯堿(jian)化(hua)工(gong)技(ji)術(shu)(shu)，其中燒堿(jian)生產(chan)中采用的離子(zi)膜法制燒堿(jian)工(gong)藝(yi)(yi)和膜式蒸發片堿(jian)工(gong)藝(yi)(yi)，聚(ju)氯乙烯聚(ju)合(he)(he)采用的１１０立方米聚(ju)合(he)(he)釜、懸浮(fu)法聚(ju)合(he)(he)生產(chan)工(gong)藝(yi)(yi)技(ji)術(shu)(shu)，單條生產(chan)線２０萬噸(dun)／年(nian)的汽提(ti)裝置及沸騰(teng)床內(nei)熱干燥工(gong)藝(yi)(yi)及技(ji)術(shu)(shu)，處于國(guo)內(nei)領先水平。
在國際石油緊(jin)缺，乙烯(xi)價(jia)格持續走高的形(xing)勢下，電(dian)石乙炔生產(chan)工(gong)(gong)藝具有原料(liao)(liao)豐(feng)富廉價(jia)、工(gong)(gong)藝穩定、成(cheng)本(ben)低廉等優點。中鹽(yan)吉(ji)蘭泰100萬(wan)噸(dun)聚氯(lv)乙烯(xi)項(xiang)目一(yi)期(qi)工(gong)(gong)程(cheng)于(yu)２００７年９月(yue)(yue)２８日(ri)竣工(gong)(gong)，經過(guo)(guo)反復調試(shi)運行，今(jin)年３月(yue)(yue)份(fen)已經投入正(zheng)常生產(chan)。隨即，中鹽(yan)吉(ji)蘭泰鹽(yan)化(hua)集團組(zu)織實施(shi)年產(chan)２０萬(wan)噸(dun)聚氯(lv)乙烯(xi)二期(qi)工(gong)(gong)程(cheng)。二期(qi)工(gong)(gong)程(cheng)包括２０萬(wan)噸(dun)／年聚氯(lv)乙烯(xi)、１８萬(wan)噸(dun)／年燒堿、６０萬(wan)噸(dun)／年電(dian)石配套項(xiang)目。今(jin)年５月(yue)(yue)，通過(guo)(guo)面向社(she)會公(gong)開(kai)招標，中國化(hua)學(xue)工(gong)(gong)業第二建(jian)(jian)筑(zhu)公(gong)司、內蒙古第三建(jian)(jian)筑(zhu)公(gong)司成(cheng)功競標。施(shi)工(gong)(gong)單(dan)位中標后，立(li)即組(zu)織廠區的“三通一(yi)平”工(gong)(gong)作，目前(qian)，已完成(cheng)材(cai)料(liao)(liao)準備，施(shi)工(gong)(gong)機具全(quan)部到達現場。乙炔工(gong)(gong)序土建(jian)(jian)工(gong)(gong)程(cheng)正(zheng)在開(kai)槽，聚合工(gong)(gong)序離(li)心干燥(zao)土建(jian)(jian)工(gong)(gong)程(cheng)６月(yue)(yue)初開(kai)工(gong)(gong)。
設(she)備(bei)訂(ding)購于年(nian)初已完成(cheng)招投標工(gong)(gong)作，確定了供(gong)貨單位(wei)。進口設(she)備(bei)、長(chang)加(jia)工(gong)(gong)周(zhou)期設(she)備(bei)將于９月(yue)份到貨。二期工(gong)(gong)程將于今年(nian)年(nian)底建成(cheng)投產。
