SINCE 2007

Changzhou Ruihua Chemical Engineering Technology Co., Ltd. was established in 2007 and is located in the Science and Education City of Wujin District, Changzhou City. It is a professional company with a number of patented technologies and mainly engaged in engineering and technical services in the petrochemical field. The company was formerly known as Changzhou Ruihua Chemical Engineering Technology Co., Ltd., which completed the share reform in December 2017 and officially changed its name to Changzhou Ruihua Chemical Engineering Technology Co., Ltd. In July 2018, it was officially listed on the New Third Board (Ruihua Technology 872869). Since the establishment of the company, the business has maintained rapid growth. It has established good business contacts with large domestic and foreign petrochemical companies; and has established stable cooperative relations with domestic and foreign chemical companies, engineering companies, patent dealers, various industry associations, large design institutes, and research institutes. As a professional company engaged in engineering and technical services in the petrochemical field, Ruihua Chemical is committed to providing users with comprehensive, systematic and professional engineering services and helping users create value. A modern enterprise that gathers elite talents and establishes a technical base is Ruihua Chemical's goal and the road of development that Ruihua is taking. In addition, the company attaches great importance to the protection of intellectual property rights, and has applied for and authorized more than 60 patents.

The company cooperates with Changzhou University to open the information inquiry channel of Changzhou University Library, relies on the analysis and testing center of Changzhou University to support the experimental analysis, and carries out industry university research cooperation on divinylbenzene, maleic anhydride, butane isomerization and other projects. The company also cooperated with Shanghai Jiaotong University to establish a pilot test platform for the catalyst, and carried out pilot production test for the developed new catalyst, so as to solve the problem of production scale-up.

Based on the existing domestic styrene technology, the company has developed a new type of large-scale reactor and unique high-temperature pipeline engineering treatment technology. The successful and stable operation of the 300,000 tons/year styrene complete technology plant has promoted the progress of domestic large-scale styrene complete technology. The company attaches great importance to the scientific and technological and research work of the enterprise. Every year, 15% of the operating income of the year is invested in the research and development of project technology. The research and development of single styrene complete technology projects has invested 46 million yuan in recent years. Obtained gratifying results. Ruihua Company has always paid attention to the development of science and technology, and vigorously promoted the cooperation of industry, university and research.

Since 2012, the company has signed a laboratory cooperation agreement with Beijing University of Chemical Technology to build a chemical and chemical laboratory, equipped with more than 10 sets of fixed bed reaction devices, isothermal bed reaction devices, 5 gas chromatographs, liquid chromatography Analyzer and other analytical testing equipment, 2 sets of 20L polymerization reactor, 1 set of falling film hydrodynamic test equipment, and other physical and chemical analysis and experimental equipment.

Subsequently, the company cooperated with Changzhou University to set up a data query channel for the library of Changzhou University, relying on the analysis and testing center of Changzhou University to support experimental analysis, and carried out production on projects such as divinylbenzene, maleic anhydride, butane isomerization, etc. Study and research related cooperation. The company also cooperated with Shanghai Jiaotong University to establish a catalyst pilot test platform to conduct trial production tests on the developed new catalysts to solve the problem of production scale-up.
