Jiangsu carbon tetrachloride conversion project passed acceptance
A few days ago, the national compliance project led by Jiangsu Meilan Group to convert carbon tetrachloride into methyl chloride successfully passed the project acceptance inspection organized by the State Environmental Protection Administration. This milestone marks a significant step forward in China's efforts to manage and repurpose ozone-depleting substances.
Carbon tetrachloride is a well-known ozone-depleting substance, and with the gradual implementation of China’s CTC (carbon tetrachloride) phase-out plan, its use as a raw material in the production of Freon, as a chemical additive, or as a cleaning agent has been or is being phased out. As a result, finding new applications for large quantities of carbon tetrachloride has become an urgent task. The goal is not only to utilize surplus CTC but also to ensure full compliance with international agreements on its phase-out.
To support this effort, the State Environmental Protection Administration allocated funds as part of a pilot program. Beijing University of Chemical Technology conducted research on the conversion of carbon tetrachloride into methyl chloride, achieving promising initial results. After evaluating multiple companies, the administration selected Jiangsu Meilan Group, which had passed laboratory tests, to conduct industrial-scale trials. In November 2004, both parties reached a cooperation agreement.
Meilan Group halted production at one of its plants and initiated a conversion project, anticipating a favorable market for methyl chloride. Drawing on the lab findings from Beijing University of Chemical Technology, Meilan’s engineers developed and constructed the first industrial-scale conversion facility in China within just six months, launching it in May 2005.
Recently, an expert review team composed of representatives from the World Bank and provincial and municipal government departments, under the supervision of the State Environmental Protection Administration, conducted the final project acceptance. Following a detailed review of the project report, on-site inspections, and thorough discussions, the experts confirmed that the system operates efficiently and meets all contractual requirements. The technical data provided was complete, accurate, and reliable. The project was recognized as filling a critical gap in China, showcasing advanced technology, and delivering substantial environmental and social benefits. It was unanimously approved for acceptance.
At the same time, the experts encouraged Meilan Group to further refine and optimize the technology, expand the application of the achieved results, and play an even greater role in ensuring national compliance with environmental regulations.
