Chenguang Institute won the award for tetrafluoroethylene cracking method
The Zhongyao Chenguang Research Institute of Technology recently received the 10th China Patent Excellence Award for its innovative patent on the external heating method for pyrolysis of tetrafluoroethylene (F22) and water vapor. This groundbreaking technology addresses long-standing challenges in the production of F22, offering a more efficient and sustainable approach.
Currently, the production of tetrafluoroethylene is mainly carried out through two methods: air tube cracking and water vapor dilution cracking. Among these, the water vapor dilution method is widely used in industrial settings due to its high conversion rate and minimal by-products. However, it suffers from several drawbacks, including excessive water vapor usage, high energy consumption, and a relatively short lifespan for the furnace tubes.
To overcome these limitations, the Chenguang Institute developed an advanced external heating system that combines superheated steam with F22 before introducing it into a specially designed reaction chamber. This process not only enhances the efficiency of the pyrolysis reaction but also allows for better temperature control during the cracking process. After the reaction, the mixture is cooled and purified through quenching and distillation to obtain high-purity tetrafluoroethylene monomer.
The key advantages of this technology include lower stress on the furnace tubes, longer service life, and easier temperature regulation. Additionally, the byproduct hydrochloric acid produced can reach concentrations of 10% to 20%, which is highly valuable for other industrial applications. Compared to traditional adiabatic reaction methods, this innovation reduces energy consumption by 15% to 30% and lowers operating costs by approximately 10%. Most importantly, it enables a cleaner and more environmentally friendly production process, aligning with global trends toward sustainable manufacturing.
This award highlights the institute's commitment to technological advancement and environmental responsibility, marking a significant milestone in the development of fluorine-based chemical processes.
