Because of the characteristics of high temperature and low pressure, the thermal oil heater becomes an important piece of equipment of the fine chemical industry. Wuhai Shilian Environmental Protection Technology Co., Ltd. was established in April 2018. With a total investment of 320 million yuan, the company was a reorganization of Wuhai Black Cat Sanxing Fine Chemical Co., Ltd. After sufficient market research and technical demonstration, Wuhai Shilian decided to re-plan the product structure of the original company and invest a 20,000-ton-per-year phenol series technology transformation project including 10,000 tons annual output of resorcinol, which is mainly used for rubber adhesives.
