The ethylene glycol project at Sino Salt Hongsi Fang is scheduled to begin trial operation in July. Author/Source: Yahuah Coal Chemicals; Date: 2018-06-13; Clicks: 60. Sinochem Seventh Construction Company is primarily responsible for the construction and installation of the DMO unit for the second phase of the Hongsi Fang ethylene glycol project. DMO stands for dimethyl oxalate, which is an intermediate product used in the production of ethylene glycol. This unit utilizes core technology provided by Ube Industries Ltd. of Japan; it features a high level of technical complexity, numerous processing steps, a large scale, and precise installation requirements. Therefore, whether the DMO unit can complete the installation tasks on time and to a high standard plays a decisive role in the smooth commissioning of the entire Phase II project and in achieving benefits at an early stage. According to Gao Xinzhong, the chief engineer in charge of construction and installation at Sinochem 7th Construction, the construction and installation work for the DMO plant involves nearly ten processes such as synthesis in three different series, compression, and distillation. With an annual production capacity of 600,000 tons of DMO, this part accounts for one-sixth of the total investment in the second-phase project. The entire facility comprises 313 pieces of equipment, over 110,000 meters of pipes of various sizes, 390,000 welds, and 910 tons of custom-made equipment; its volume of work ranks first among all the construction sections. Strategic planning is key to achieving victory from afar. Sinochem 7th Construction firmly upholds the concepts of \"winning with every step\" and \"the construction period being the greatest asset\", striving to achieve speed while maintaining stability and quality. Despite facing challenges such as the relatively late delivery of initial construction drawings, the delayed arrival of equipment and installation materials, and the enormous volume of work required in the later stages, Sinochem 7th Construction Company, as the contractor working with Hong Sifang for the first time, did not back down. It mobilized the strengths of its various specialized teams, increased manpower and machinery, set clear goals, strengthened its measures, strictly adhered to the schedule, established a timeline, focused on key milestones, and relied on actual results to demonstrate its performance. The company focuses on safety, quality, schedule, cost, and civilized construction to carry out its tasks effectively on a phased basis. At the same time, detailed arrangements should be made, careful planning undertaken, and management strengthened to minimize factors that could affect the schedule. Wang Xiaohua, the manager of the ethylene glycol department at Hong Sifang who is in charge of this project, also highly praised the work done by Sinochem 7th Construction. He said that since resuming work after this year’s Spring Festival, Sinochem 7th Construction has made meticulous plans to meet the target deadlines set by Hong Sifang. Since March 15, the construction team has seen an increase of over 100 members; it currently has a strength of more than 400 people, with hundreds of them working overtime on night shifts for over 70 days in a row. To improve efficiency, the management team of Sinochem No.7 Construction Project Department assigns dedicated personnel every day to deliver dinner to the site, thereby enhancing construction efficiency. Advance work in accordance with the overall project schedule established by Hong Sifang, implement incentive mechanisms, develop internal construction plans, and ensure their implementation at each level. At present, the installation work for the main units has been largely completed, and the pressure testing of the pipelines is nearing its end; they have been delivered to the production workshop for purging. Practice has proven that Sinochem 7th Construction is a first-class team with high professional standards, strong comprehensive capabilities, a willingness to endure hardships, and the ability to take on tough tasks. At the site, Gao Xinzhong pointed to the rows of storage tanks that were now taking shape and said with confidence: As of now, the civil engineering work for the DMO unit of the ethylene glycol project, as well as the steel structure construction for various units, has been completed. 95% of the ground surface has been paved, and all around 300 pieces of mechanical and electrical equipment have been installed, 100% of them. The custom-made storage tanks in the intermediate tank area have also been installed 100%, and all the process pipelines for the various units have been constructed 100%. Pressure testing is 90% complete, and some of the equipment has already been handed over to the production department for purging. 90% of the electrical instrument installation has been completed ； The construction of the civil main structure of the 91B external pipe gallery and the steel structure work for the pipe gallery have been 100% completed, while approximately 80% of the external pipes worth around 100,000 yuan have been installed. The key tasks in June will be the piping and pressure testing of the remaining pipes in the external pipe gallery, as well as the final adjustments such as individual testing of the operating equipment and calibration of the instruments. Additionally, efforts will be made in coordination with the production workshop to carry out purging, airtightness testing, and joint commissioning, so as to ensure that the facility is ready for trial operation at the beginning of July. He said that Sinochem No.7 Construction has the confidence and capability to complete the remaining construction tasks safely and efficiently, and to achieve the goal of a successful first start-up of the plant.
