Comprehensive equipment upgrade and renovation of the PVC production line at Yihua in Inner Mongolia
Thread Content
Inner Mongolia Yihua Chemical Co., Ltd. is going to carry out a comprehensive upgrade of the equipment on its PVC production line. This upgrade and renovation project is scheduled to cost 150.06 million yuan; it will involve technical upgrades to 105 production lines within the Yihua plant, including polymerization units, vinyl chloride recovery units, slurry stripping units, drying units, and packaging units. In addition, auxiliary facilities such as desalinated water tanks and monomer buffer tanks will also be installed. Upon the completion of this project, the PVC production capacity at the Yihua plant is expected to reach 300,000 tons per year. Meanwhile, an additional PVC polymerization production line with a capacity of 150,000 tons will be added to the plant, which seems to ensure a stable supply of PVC for Yihua.
As the core equipment for this project, the lifting of the polymerization reactors is certainly a key focus of this upgrade. But there’s no need to worry – just recently, all three polymerization reactor units were successfully lifted at once. The successful installation of these devices can be considered a good start for the entire project; it is likely that larger equipment such as slurry tanks and fluidized beds will also be able to achieve success by building on this momentum.

Inner Mongolia Yihua Chemical Co., Ltd. The predecessor of Inner Mongolia Yihua was Haiji Chlor-Alkali Chemical Co., Ltd. In May 2009, Hubei Yihua Group took over all of Haiji Chlor-Alkali’s assets and employees, thereby establishing Inner Mongolia Yihua Chemical Co., Ltd. At present, the company is accelerating the construction of projects in line with its goal of establishing a chlor-alkali industry base in China. The first phase of the Yihua project in Inner Mongolia, with a total investment of 4 billion yuan, is already under construction; this phase aims to produce 600,000 tons of calcium carbide, 400,000 tons of caustic soda, 400,000 tons of PVC, and 200,000 tons of sodium formate per year. This project takes advantage of Yihua’s comprehensive technical strengths. From the handling of preliminary procedures, commencement of construction, equipment installation to completion and commissioning, the entire process is planned to be finished within half a year. The project will go into operation on December 31, 2009, setting a new record for the speed of project construction of similar scale in China’s chlor-alkali chemical industry. Upon completion of the project, it is expected to generate an additional output value of 5.215 billion yuan and profits and taxes of 1.039 billion yuan, while providing employment for over 1,000 people. By then, the PVC production capacity of Inner Mongolia Yihua will reach 480,000 tons, making it the leading enterprise in the chlor-alkali chemicals industry in Wuhai City. Yihua in Inner Mongolia plans to expand its production capacity by another 400,000 tons of caustic soda and 400,000 tons of PVC next year, aiming to reach a total production capacity of 1.35 million tons of calcium carbide, 880,000 tons of PVC, 860,000 tons of caustic soda, and 400,000 tons of sodium formate, thus becoming the largest chlor-alkali chemical manufacturer in the country.

According to China Quality News Network, recently the power plant of Inner Mongolia Yihua Chemical Co., Ltd., a large-scale chemical enterprise in Wuhai City, was shut down for maintenance. As the scheduled external inspection of the boiler had arrived, the company submitted an application for such an inspection to the Wuhai Special Equipment Inspection Institute in Inner Mongolia, based on its own inspections and assessments. The inspectors promptly arranged the inspection, and it was completed successfully. The Power Workshop of Inner Mongolia Yihua Chemical Co., Ltd. is equipped with 4 power station boilers, each with a capacity of 130 t/h. These boilers were put into operation in the early 1980s, and their operating time has now exceeded 100,000 hours. In order to help the company resume production as soon as possible, the boiler inspection staff from Wuhai Special Equipment Inspection Institute developed a detailed inspection plan taking into account factors such as the long operating time of these boilers, their high operating parameters, as well as the severe wear and complexity of the equipment. According to this plan, thorough inspections were carried out on the boilers themselves and their auxiliary equipment, water quality, safety accessories and protective interlocks, as well as various safety procedures and the certificates of the operators. Inspection reports were issued promptly based on the results of these inspections. The inspectors also provided technical support for the projects that the company had failed to rectify properly on previous occasions, helping it make the necessary corrections and determine appropriate solutions. The implementation of this inspection was carried out under the guidance of the technical supervisor, in line with the principle of serving the enterprise; it not only fulfilled the required inspection tasks but also helped resolve practical problems for the enterprise, earning its recognition and praise.
