Shanghai Daoqin Plastics Co., Ltd.

         although pure degree improve/increase 0.01%, is for/regarding process 说, is 一 质 飞跃. 截至11 month 18 day, 青岛海湾 group lower 青岛海湾 chemical has company chlorine ethylene production chlorine ethylene (VCM) product 33.6 10,000 tons, pure degree to 99.99% chlorine ethylene product output/production volume 91%, ultra- 出 patent to pure degree 99.98% 考核 indicators.

        海湾 chemical 40 10,000 tons / year chlorine ethylene plant/unit 于2016 year 10 month positive start production, is currently inner using/adopting ethylene method made chlorine ethylene mono sleeve/set production capacity most large plant/unit. plant/unit construction start 以, chemical according to patent to pure degree indicators, will product pure degree control in 99.98%. high quality development speed degree add fast, group year for product pure degree new requirements.

        决定 chlorine ethylene product pure degree key/critical factors has raw materials pure degree, in product pure degree, understanding 效果, separation 离效果 and other. “今 year 4 month 末, 我们开展 will chlorine ethylene pure degree improve/increase 0.01% technology 攻关. through analysis and causes, most 终确定 need is chlorine ethylene mono in chlorine and chlorine content high, product pure degree difficult breakthrough 99.98%. ”该 company chlorine ethylene long 孙业涛说.

        孙业涛 introduction 说, 进一步 causes analysis 显示, understanding reaction generate more, 精馏塔精馏效果不 good and understanding raw materials chlorine pure degree high this 三方面 causes formed pure degree indicators breakthrough 局限.

        该厂 technology for a large amount of production data related property analysis, high temperature chlorine reaction device liquid pure degree and most product quality in positive related property. also 邀请精馏 expert analysis process for product pure degree effect/influence, most 终 出塔盘开孔 rate, negative and ratio and other is 决定精馏效果 important factors.

        找 to causes, need for lower 药. 该厂首先 improve/increase in raw materials chlorine pure degree, for high temperature chlorine reaction 情况进行实时 large data testing analysis, most to combined reaction temperature degree and liquid pure degree.

        “ another, is 精馏塔 溢流形式, 塔盘开孔 rate and other hard parts is solid 定, can through adjustment pressure and temperature degree degree control product in content. through 反复 实验 ratio for, 我们确定 精馏塔 most 佳运行状态, 精馏塔 运行工况 to improvement, product content reduce. ”孙业涛说.

         through optimization adjustment, from 5 month 开始, pure degree to 99.99% chlorine ethylene product ratio/proportion month improve/increase, 7 month ratio to 90% above, 但1,2-二 chlorine and chlorine ethylene pure degree still has improves 空间. technology through research 发现, improves oxygen chlorine generate 1,2-二 chlorine pure degree also has drop consumption 效果. meanwhile, also reaction raw materials in has is generate main/primary causes 之一, is for raw materials add hydrogen 技改也随即开始实施.

        “乙炔 add hydrogen 技改实施 rear, expected year can ethylene 330吨, 避免 副 reaction 发生, reduce material can consumption, year expected can 创造经济效益约215 10,000 yuan. currently, add hydrogen reaction device positive in add 紧施工, pressure shrink machine, reaction device, catalytic agent already procurement. ”孙业涛 introduction 说.
