截至8月底，独山子石化塔里木120万吨/年二期乙烯项目配套的45万吨/年聚丙烯装置已生产合格产品达5.5万吨，装置负荷稳定在90%以上。这标志着中国石油自主知识产权聚丙烯成套技术成功完成工业化应用，为中国石油炼化产业自主可控、向新材料高端赛道转型筑牢关键支点。

As of the end of August, the 450,000-ton/year polypropylene plant, which is a supporting project for the 12 million-ton/year second-phase ethylene project of Dushanzi Petrochemical in Tarim, has produced 55,000 tons of qualified products. The plant's operating load has remained above 90%. This indicates that China Petroleum's proprietary polypropylene complete technology has successfully completed industrial application, laying a crucial foundation for China Petroleum's independent control of its refining and petrochemical industry and its transition to the high-end arena of new materials.

中国寰球工程有限公司作为专利商及EPC总承包方，将自主技术转化为矗立在荒漠的现代化装置，以全链条自主创新，在高端聚烯烃国产化进程中实现了里程碑式的突破。

China Global Engineering Co., Ltd., as the patent holder and EPC general contractor, has transformed its own technologies into modern facilities standing in the desert. Through a full-chain independent innovation process, it has achieved a landmark breakthrough in the domestication of high-end polyolefins.

从“学习国外”到“自成一派”，因地制宜形成自己的技术路线

From "learning from abroad" to "forming one's own school of thought", adapt to local conditions and develop one's own technical approach.

聚丙烯是现代工业刚需原料，但其核心技术长期被国外垄断。为了真正掌握聚丙烯产业发展主动权，集团公司2017年立项聚丙烯大型成套工艺工业化项目，由寰球工程公司负责工艺包开发与工程转化。从事聚合物研究多年的寰球北京公司工艺部首席工程师刘灿刚，带领团队接下这一重任。

Polypropylene is a necessary raw material for modern industry, but its core technology has long been monopolized by foreign countries. In order to truly gain control over the development of the polypropylene industry, the group company initiated a large-scale industrialization project for the polypropylene process technology in 2017. The Global Engineering Company was responsible for the development of the process package and the engineering transformation. Liu Cangang, the chief engineer of the process department of Global Beijing Company, who has been engaged in polymer research for many years, led the team to take on this responsibility.

工艺包开发的第一道坎是反应器组合的技术路线选择。刘灿刚团队经过反复论证，最终决定在国外通用技术的基础上，形成自己的技术路线。

The first hurdle in the development of the process package was the selection of the technical route for reactor combination. The team led by Liu Can Gang conducted numerous discussions and finally decided to develop their own technical route based on the common technology available abroad.

“开发新的工艺包意味着更高的设计难度和更大的风险。但只有这样，才能为未来开发高端产品留下空间。”刘灿刚说，这个选择让团队多花了近2个月的时间来做模拟计算。

"Developing a new process package means higher design complexity and greater risks. But only in this way can we leave room for the development of high-end products in the future," said Liu Cangang. This choice required the team to spend nearly two months doing simulation calculations.

设计中每一次碰撞都是为了质量的提升。独山子石化对首套工艺包格外审慎，设置了多轮审查严格把关，每一轮都有几十条甚至上百条意见。“到详细设计阶段，业主还请外部专家再审，首席专家亲自审，一根根管线过。”设计经理梁涛说，“优化建议出来后，我们经常连夜调整方案，赶在节点前提交新版的图纸。”

Every collision in the design is aimed at improving quality. Daoshan Petrochemical was particularly cautious about the first process package, conducting multiple rounds of reviews to strictly control the quality. Each round involved dozens or even hundreds of suggestions. "By the detailed design stage, the owner also invited external experts for another review. The chief expert personally reviewed, and each pipeline was examined one by one," said Liang Tao, the design manager. "After the optimization suggestions were made, we often adjusted the plan overnight and submitted the new version of the drawings before the deadline."

12个月的设计周期压力非凡，聚丙烯项目部依靠高度协调稳稳顶住。设计遇到瓶颈，主动组织专家会诊；采购周期紧张，积极协调公司资源倾斜，确保图纸、设备材料按时到货。就这样，施工图按时发出，模块化设计、料仓法兰连接等创新方案一一落地。

The 12-month design cycle was extremely challenging. The polypropylene project department relied on high-level coordination to weather the storm successfully. When design encountered bottlenecks, they actively organized expert consultations; when the procurement cycle was tight, they actively coordinated the company's resources to ensure that drawings and equipment materials arrived on time. Thus, the construction drawings were issued on schedule, and innovative solutions such as modular design and flange connection for the silos were all implemented.

从“高价引进”到“中国心脏”，精心谋划圆梦核心装备国产化

From "High-End Import" to "China's Heart", meticulously planning to realize the goal of domestic production of core equipment

如果说工艺包是装置的“大脑”，那么核心装备就是“心脏”。“重大装备国产化同样是第一次做，很多风险叠加在一起，每一步都需要精心谋划。”聚丙烯装置项目经理赵程对这台“心脏”的重视程度非同寻常。

If the process package is the "brain" of the equipment, then the core equipment is the "heart". "The domestication of major equipment is also the first time for this, and many risks are compounded together. Every step requires meticulous planning." Project Manager Zhao Cheng of the polypropylene plant shows an extraordinary level of attention to this "heart".

从挤压机采购立项开始，他亲自参与技术谈判，带着设计团队与厂家逐条核对参数。“过去只有国外少数企业能生产，引进价格昂贵。这是国产首台（套），不能出一点差错。”干了大半辈子聚合物装置，国产化圆梦在即，他格外上心。

Since the project for purchasing the extruder was initiated, he personally participated in the technical negotiations and led the design team to carefully compare the parameters with the manufacturer one by one. "In the past, only a few foreign enterprises were capable of producing it, and the imported price was extremely high. This is the first domestically produced (set) unit, and we cannot make the slightest mistake." Having spent his entire life working on polymer equipment, he is particularly focused on this moment of domesticization realization.

从技术协议阶段起，设计团队就超前深度介入。技术协议经过多轮澄清，借鉴国外厂商经验，每一个参数都认真核实。“厂家开始觉得我们要求太多，后来发现我们的参数确实更系统、更合理。”梁涛说。签订协议后，团队还派专人到制造厂进行设计审查。

From the technical agreement stage onwards, the design team took an extremely proactive and in-depth involvement. After multiple rounds of clarification of the technical agreement, drawing on the experience of foreign manufacturers, every parameter was carefully verified. "The manufacturer initially thought we were asking for too much, but later they realized that our parameters were indeed more systematic and more reasonable," said Liang Tao. After signing the agreement, the team also sent dedicated personnel to the manufacturing plant for design review.

质量把控同样一丝不苟。在一次例行检查中，设计团队发现液压油系统管路的技术参数需要进一步确认。独山子石化高度重视，设计团队主动组织专题会、邀请专家审查，最终对管路进行了优化更换。

The quality control was also meticulous. During a routine inspection, the design team discovered that the technical parameters of the hydraulic oil system pipelines needed further verification. Daishanzi Petrochemical attached great importance to this issue. The design team actively organized a special meeting and invited experts to review, and finally optimized and replaced the pipelines.

从技术协议到现场安装，从质量把控到运输保障，每攻克一个难题，团队的攻坚能力就跃升一个台阶。挤压造粒机组试车成功那天，当看到晶莹的聚丙烯颗粒从出料口喷涌而出时，所有的辛苦都值得了。

From the technical agreement to the on-site installation, from quality control to transportation guarantee, every time the team overcame a difficult problem, their ability to tackle challenges would increase by one level. On the day when the extrusion granulation unit was successfully tested, when seeing the crystal-clear polypropylene particles gushing out from the discharge port, all the hard work was worth it.

从“人海战术”到“模块革命”，优化流程装置提前30天中交

From "mass tactics" to "module revolution", the process equipment was completed and handed over 30 days ahead of schedule.

执行项目，工期不是“抢”出来的，而是“优”出来的。这个想法，在两年前聚丙烯装置的施工经理何明明第一次踏入现场的时候，就出现在他的脑海里。

Carrying out the project, the construction period is not "forced" but "optimized". This idea first occurred to He Mingming, the construction manager of the polypropylene plant, when he first stepped onto the construction site two years ago.

统筹部署、科学决策、精细管控是起点也是基石。何明明带领施工团队白天做开工准备、晚上编制策划，仅用一周时间便完成了所有开工手续及施工策划的报审工作。赵程则提出“以模块化保进度、以预制化提质量”的总体思路，从全局高度把控施工节奏。

Overall planning, scientific decision-making, and meticulous control are the starting point and foundation. He Mingming led the construction team to prepare for the start of the project during the day and prepare the plans at night. Within just one week, he completed the submission of all the approval procedures for the start and the construction planning. Zhao Cheng proposed the overall strategy of "ensuring progress through modularization and improving quality through prefabrication", and controlled the construction pace from a strategic perspective.

模块化的前提是设计的超前介入。“荷载条件要提前提给制造厂，吊点位置必须极其准确，设计进度被迫提前，核心区域在详细设计开始前就要先做。”赵程逐一协调设计与施工的衔接，多次组织召开设计与施工联队会，确保“设计有方向、施工有图纸、现场有材料”。

The prerequisite for modularization is the early involvement of the design. "Load conditions must be provided to the manufacturing plant in advance, the position of the lifting points must be extremely accurate, the design schedule has to be advanced, and the core area must be prepared in detail before the detailed design begins." Zhao Cheng coordinated the connection between design and construction one by one, organized multiple design and construction joint meetings, and ensured that "the design has a direction, the construction has drawings, and the site has materials."

“钢结构工厂预制、现场模块化吊装，管道工厂化预制、大口径自动焊接。”何明明说，“依靠工序优化和装备升级，工期的缩短显而易见。”

"Steel structure is prefabricated in the factory and then lifted and installed on-site in a modular manner. Pipelines are prefabricated in the factory and automatically welded with large diameters." He Mingming said, "Thanks to process optimization and equipment upgrading, the shortening of the construction period is quite obvious."

项目创造了一系列纪录：10天完成8次大型吊装，3天吊装600吨钢结构，环管反应器实现“塔起灯亮”，装置提前30天中交。

The project set several records: completing 8 large-scale hoisting operations in just 10 days, hoisting 600 tons of steel structure in 3 days, and achieving the "lighting up of the tower" for the loop reactor. The project was handed over 30 days ahead of schedule.

戈壁滩上，有这样一群人，用4年时间，把“寰球芯、中国造”刻进了一颗颗聚丙烯颗粒里。而中国石油的聚丙烯之路，从这一刻起，自己说了算。

On the desert of the Gobi, there is such a group of people. Over a period of four years, they etched the words "Global Core, Made in China" into each piece of polypropylene resin. From this moment on, the path of China Petroleum's polypropylene production is now in their own hands.
