Rongxin Chemical’s 400,000-ton ethylene glycol production project has entered the commissioning phase with its production process now fully operational

Thread Content

On June 30, the synthetic distillation unit and ethylene glycol unit under construction as part of Rongxin Chemical’s Phase II project completed successful water-based commissioning tests. This successful completion of the process flows at the end of the system marked the entry of the entire Phase II project into the debugging phase, thereby achieving the goal set by the group company to have the processes operational by the end of June. The second phase of Rongxin Chemical’s project, with an annual production capacity of 400,000 tons of ethylene glycol and 300,000 tons of polydimethyl ether, began construction in August 2017. The total investment required was 7.68 billion yuan, and the project covers an area of about 1,268 mu. Using coal as the raw material, and taking advantage of the resources and capacity available from the first phase’s coal-to-methanol production facility, this project utilizes processes such as gasification, conversion, purification, synthesis, and distillation to produce chemical products like ethylene glycol and polydimethyl ether. It helps to extend the industrial chain and increase the added value of these products. It represents an important step in advancing the integration of the coal chemical industry, as well as a necessary factor for the development of regional industrial clusters. During the construction phase, as the group company’s first true EPC turnkey project, Rongxin Chemical overcame numerous challenges such as a large scale of work, tight deadlines, and complex construction conditions. It actively implemented plans for \"intelligent and information-based\" construction methods, striving to create a \"smart chemical manufacturing site.\" There were over 40 construction companies involved on site, along with more than 5,000 workers. By promoting standardized construction procedures, bringing in fourth-party quality inspection agencies and local special inspection organizations to the site, implementing strict systems for ensuring the quality of personnel, equipment, processes, and the surrounding environment as well as for tracking responsibilities, and adopting a \"dual approval system,\" thorough monitoring throughout the entire construction process was ensured, thus guaranteeing safe and efficient construction quality. Located on the northern border of Inner Mongolia, Rongxin Chemical operates in a frigid region where winter temperatures can drop to minus 30 degrees. Since the start of construction, it has faced two winter shutdown periods; Rongxin Chemical, together with the construction teams, has made every effort to carry out the work. During this year’s Spring Festival, the project entered the pipeline welding phase. The workers on site did not take any holidays and continued to weld 24 hours a day inside the temporary insulation shelters, ensuring that the project milestones were met on schedule. The construction of the second-phase project has also received attention and support from local authorities. The on-site observation meeting on the transformation of old and new economic drivers as well as the high-quality development of enterprises in Inner Mongolia was held at Rongxin Chemical. Li Jiheng, Secretary of the Party Committee of Inner Mongolia Autonomous Region, and Bu Xiaolin, the regional head, visited the site in person to provide preferential procedures for the project’s construction. It is reported that once completed, the project will be able to generate an annual output value of 3.5 billion yuan and annual profits and taxes of 1 billion yuan.
