Good News!

Recently, the SABIC PKN MTBE Improvement Project, which is EPC contracted by CNCEC-TCC, has successfully commenced production and entered commercial operation one month ahead of schedule. This milestone marks the official completion of the world's largest single-train MTBE production base.

As the largest-scale SABIC own technology project under cooperation between CNCEC-TCC and SABIC, the core breakthrough of this plant lies in the integration of a new-generation isobutane dehydrogenation production process and a regeneration air compressor with the world's largest processing capacity. The project involves constructing a new isobutane dehydrogenation unit to replace PKN's existing unit, while synchronously implementing technological upgrades to the upstream and downstream n-butane isomerization unit, MTBE synthesis utilities, and auxiliary facilities. This technological upgrade will bring multiple benefits: utilize 10 MW electricity recovery by low-pressure steam, and the extension of the MTBE synthesis unit's continuous operation cycle from 8 months to 2 years, achieving significant breakthroughs in the fields of green chemical industry upgrading and low-carbon environmental protection practices.

近日，中国化学天辰公司总承包的沙特SABIC PKN MTBE项目迎来重要里程碑时刻——项目较计划提前一个月顺利投产并实现商业运营，标志着全球规模最大的单体甲基叔丁基醚（MTBE）生产基地正式落成，为中沙企业合作树立全新典范。

作为天辰公司与沙特基础工业公司（SABIC）合作的最大体量专有技术工程，项目新建异丁烷脱氢装置以替换PKN现有装置，同步对上下游正丁烷异构化装置、MTBE合成公用工程及辅助设施进行技术升级。项目建成后，MTBE年产能将从70万吨提升至100万吨，跃居全球单体规模之首。该项目不仅提前4天完成机械竣工，更较计划提前一个月完成投料并产出合格产品，充分彰显出天辰公司卓越的履约能力与高效的执行能力。

作为SABIC首个全面采用自有专利技术的MTBE项目，该装置的核心突破在于集成新一代异丁烷脱氢生产工艺与全球最大处理能力再生压缩机。此次技术升级将带来多重效益，通过回收副产低压蒸汽可实现10MW电力自给，每年约减少催化剂消耗6300吨；MTBE合成单元连续运行周期从8个月延长至2年，设备可靠性与环保性能均达到行业顶尖水平，在绿色化工升级与低碳环保实践领域实现显著突破。

项目实施期间，面对国际供应链波动、高温沙尘气候、老厂施工作业难度大等多重挑战，天辰公司项目团队依托深耕沙特市场12年的经验积淀，创新实施“设计—采购—施工深度协同模式”，为项目高效有序推进提供了坚实保障。在试车阶段，项目团队全体人员实行多班组轮值、日夜奋战，高效配合业主完成各工艺单元的单体试车。项目最终不仅提前完成投料并产出合格产品，更获得SABIC业主的高度赞誉。此次项目的成功实施，充分彰显了“艰苦奋斗、团结协作、模式创新、尽善服务”的沙特团队精神，为公司深耕沙特及中东市场筑牢坚实基础。
