About the SINOPEC-SABIC Joint Venture and the Tianjin Projects
SINOPEC SABIC Tianjin Petrochemical Co., Ltd.,
SINOPEC SABIC Tianjin Petrochemical Co., Ltd. (SSTPC), a 50/50 joint venture between Saudi Basic Industries Corporation (SABIC) and China Petroleum & Chemical Corporation (Sinopec), has constructed a huge, integrated refinery and petrochemical complex in Tianjin, China. The petrochemical facility at this complex was built at a total cost of 18.3 billion RMB (US$2.7 billion) and has an annual capacity of 1.0 million tons ethylene and the remainder is downstream products such as polyethylene, ethylene glycol, polypropylene, butadiene, phenol, and butene*.
The ethylene cracker, eight downstream units, and all associated utilities took just 27 months to build and began commercial production in May 2010 after a three month pilot operation phase during which ethylene production capacity was ramped up to the present annual capacity of 1.0 million tons. The refinery initially had a production capacity of 5.0 million tons, but this was soon increased to the present 15.0 million tons.
In addition to expanding local production, the complex will upgrade the chlorine-alkaline industry in Tianjin and promote economic development of the New Binhai District and Tianjin municipality. Initial estimates indicate this will support an annual GDP increase of more than four percent in Tianjin and trigger investment of an additional 100 billion RMB (US$14.8 billion) in downstream and associated industries.
*Capacities for other downstream products produced at the Tianjin petrochemical facility: Gasoline hydrogenation: 650,000 tons, LLDPE: 300,000 tons, HDPE: 300,000 tons (INEOS Innovene S process), PP: 450,000 tons (LyondellBasell Spherizone PP), EOEG: 420,000 tons (Dow technology), Phenol: 350,000 tons, butadiene, 200,000 tons, MTBE: 120,000 tons, butane: 50,000 tons
The Challenges and the Solutions
SSTPC wanted to achieve a major increase in production capacity through the construction of large-scale and fully integrated oil refining and petrochemical production facilities. The company was looking to achieve specific cost, safety, and environmental protection targets, and required a partner with high quality project execution capabilities. To accomplish these objectives and meet these challenges, SSTPC turned to Yokogawa. As the main automation vendor for the refinery and petrochemical facility projects, Yokogawa successfully installed CENTUM CS 3000 production control systems, Exaquantum plant information management systems, Plant Resource Manager (PRM) packages, and over 40,000 HART field devices, including Yokogawa EJA transmitters and valves. In this undertaking, Yokogawa engineers were involved from the very early project stages and worked closely with their counterparts at the Sinopec Engineering Institute (SEI) and 10 engineering companies.
A closer look at some of the product solutions provided by Yokogawa follows.
1. Process data management is a key issue in the petrochemical complex because plant efficiency needs to be continuously monitored to prevent the occurrence of major problems that can lead to costly plant shutdowns. Once a shutdown occurs, a lot of work and energy must be expended to start it up again. Yokogawa's Exaquantum helps to prevent this by providing a window into the various processes at this huge complex by continuously analyzing their data.

2. Maintenance of thousands of HART devices throughout the refinery and petrochemical facilities would be very time consuming if field operators had to check them one at a time. With Yokogawa's PRM package, operators can determine at a glance whether field devices from Yokogawa and other vendors are in good working order. This allows a much more efficient proactive maintenance approach that results in significant savings in maintenance costs.

3.For more efficient engineering work, CENTUM CS 3000 engineering stations and other vendor's engineering stations are all together located in this room. On-Line maintenance capability of CS 3000 is very much appreciated by SSTPC engineering department.

4. Process engineers are always looking for the best control strategy to improve production efficiency and product quality. They need to confirm the current process situation and identify whether a new strategy can achieve the desired improvements. SSTPC engineers do this in the second floor system room.

Zhang Senlin, Vice Deputy Director of the Equipment Managing Department, said, "We are very much satisfactory that this huge refinery and petrochemical complex has been running very smoothly without any major problems since January 2010. We appreciate Yokogawa's project members working together as "One Team." We completed all configuration based on the same standard specifications and procedures. And we appreciate the easy configuration of the CENTUM CS 3000 system and its high reliability. It will bring huge savings in maintenance of the entire system."
석유화학 업종 고객사의 요구는 매우 다양합니다. 경쟁이 치열한 오늘날의 시장에서 앞서 나간다면, 생산자는 품질과 생산성을 향상시키기 위해 노력하고 있습니다. Yokogawa는 이 분야에서의 오랜 기간의 광범위한 경험을 바탕으로 이러한 요구에 맞는 맞춤 솔루션을 제공합니다.
화학 플랜트는 연속 및 Batch 생산 공정에 의존하며, 각각은 제어 시스템에 대한 다양한 요구 사항을 제시합니다. 연속 공정은 실패하지 않고 생산 라인을 중단시키는 견고하고 안정적인 제어 시스템을 필요로하는 반면, Batch 공정의 중요성은 수식, 절차 및 공정을 조정하는 데 있어 큰 유연성을 허용하는 제어 시스템을 갖추는 데 있습니다. 두 종류의 시스템 모두 제품의 사용 가능한 품질 내역에서 관리되어야 하며 비일상적인 작업을 수행할 수 있어야 합니다. Yokogawa는 광범위한 제품 포트폴리오, 숙련된 시스템 엔지니어 및 글로벌 영업 및 서비스 네트워크를 통해 모든 공장 공정에 대한 솔루션을 제공합니다.
