Shanghai Daoqin Plastics Co., Ltd.

12 month 18 day, 齐鲁石化烯烃厂经 combined optimization, negative relatively large 14号裂 understanding 炉顺利投 use, this is 该厂持续 optimization raw materials increase ethylene adjustment.

随 raw materials price rise, product decline, enterprise profit large pressure shrink, what to do? this 一严峻 形势摆 in 烯烃厂 full 体职工面 front, must 想尽一切办 method optimization raw materials, increase ethylene, can reduce production cost.

“乙烷 is ethylene understanding excellent raw materials, understanding use 乙烷必 must 充足, can ensure ethylene output/production volume high, ethylene rate high. ”烯烃厂 tube/pipe workshop 党支部书记刘承运说.

随 gas temperature reduce, to 该厂乙烷接卸 belt/tape difficult. negative 责乙烷接卸 tube/pipe workshop add strong/high 乙烷接卸 tube/pipe 理, increase anti anti 凝检查次数, ensure 接卸乙烷顺畅.

is reduce 乙烷接卸造 formed loss consumption, for 进厂乙烷 specification as, 每车乙烷接近接卸结束时, gas has pressure, is recycling this separation 乙烷, 职工严格操 as 程序, will gas recycling to recycling in, 避免 放空造 formed loss 失, reduce loss 失, but also achieve environmental protection 接卸. meanwhile 他们积极 and material in for 接, ensure formed light 烃, plan, has 序进厂, meet/satisfy understanding use.

“ how to excellent raw materials formed in in ethylene, add strong/high understanding 炉运行 tube/pipe is key/critical. ”烯烃厂裂 understanding workshop 副主任 high 同伟说.

is let raw materials to 极致, 烯烃厂 add strong/high understanding 炉运行监护, optimization good 石脑油, 尾油, light 烃投入, gas excellent use 乙烷裂 understanding, small use amount maintain in 11吨/ small above, improve/increase LNG乙烷投入 ratio/proportion, in, LNG乙烷投入 ratio/proportion relatively 11 month improve/increase 1.81 百 separation 点.

针 for LNG乙烷, 自产乙烷, light separation 别进入 different understanding understanding, 他们积极做 good raw materials fine separation as, combined small cycle SPYRO模拟计算 and understanding 炉定期标定 结果, 确定每 types raw materials in different understanding most 适宜 裂 understanding conditions, achieve adjustment.

is achieve light 石脑油 and 炼厂三常一线石脑油 mono understanding, 他们积极筹备, research 院模拟运行, conditions tool 备随时引入裂 understanding, is raw materials and again optimization good 准备.

他们针 for understanding low nitrogen device features, optimization adjustment, low nitrogen device 越 越 stability, in heavy 污染天 gas 应急响应 frequency 繁 情况 lower, can can maintain 5台 gas 体炉运行, ensure gas raw materials ratio/proportion in 23%, increase ethylene.

烯烃厂经 一 series raw materials optimization measures, ethylene output/production volume stability improves, to increase 产 目.
