Commissioning of Instrument Circuits for the Zhong’an United Coal Chemical Project Begins Author/Source: Date: 2018-09-18 Clicks: 37 On the afternoon of September 12, the gasification cabinet area of the Zhong’an United Coal Chemical Project, which is under EPC contracting by Ningbo Engineering Company, was bustling with activity. Dozens of workers, including the project owner, supervisors, and engineers from the DCS manufacturer, began working together on the commissioning of the gasification instrument circuits. It is reported that the gasification unit of this project utilizes the \"SE-East Furnace\" powder coal gasification technology, which features a high level of technical complexity and involves complex reactions, thus requiring a high degree of automation in the control system. Therefore, the commissioning of the instrumentation system plays a decisive role in the subsequent startup and trial operation of the plant. The gasification unit has more than 13,000 instrument circuits, resulting in tight commissioning timelines and heavy workload. The successful completion of the first loop debugging marks another solid step toward achieving the ’10•30’ delivery target. The Zhongan United Coal Chemical Project uses the \"SE-Oriental Furnace\" developed jointly by Sinopec and East China University of Science and Technology, featuring 7 gasification/quenching furnaces with a coal input of 1,500 tons per day. There are high requirements for the automation of control systems. The commissioning of the instrumentation system plays a decisive role in the subsequent startup and trial operation of the plant.

At 10:41 on August 30, Boiler No. 1 at the Zhongan United Thermal Power Plant was successfully ignited in the \"8•30\" operation, marking the entry of the utility system for Zhongan United Coal Chemical Co., Ltd.’s 1.7 million tons per year coal-to-methanol and converted olefins project into the phase of comprehensive commissioning. Since April, the Zhongan project has successively completed the handover of 8 facilities, including a 220KV substation, a circulating water plant, an air compression station, as well as desalination and condensate recovery systems. The 1.7 million tons per year coal-to-methanol and converted olefins project of Zhongan United Coal Chemical Co., Ltd. is a key construction project of Sinopec and Anhui Province. The core process of the project utilizes the S-MTO patent technology owned by Sinopec, while the gasification unit employs the SE-Oriental furnace technology also owned by Sinopec. Using coal from the Zhujixi mine as raw material, methanol and converted olefins (LDPE/PP), ethylene glycol (MEG) and other products are produced. Sinopec Engineering Construction Co., Ltd. is responsible for the overall management of the design, procurement, and construction of the MTO/OCC and PP units in this project, as well as six supporting facilities including the control room and 110 kV substation ； Sinopec Ningbo Engineering Co., Ltd. is responsible for the design and construction of the gasification unit for the contracted project ； Design and construction of the air separation unit, purification unit, and circulating water system for Sinopec’s Nanjing engineering contracting project.
