In the production of chlorinated paraffin, liquid chlorine gasification is characterized by high energy consumption and low efficiency. This study optimizes the design of a chlorinated paraffin liquid chlorine gasification system using cold water (10℃) -hot water cascade heat exchange. By innovating the heat exchanger structure and process configuration, the system achieves efficient heat recovery and utilization. Cold water absorbs the latent heat required for liquid chlorine gasification through cascade heat exchange with hot water, pre-heating it. After pre-heating, the cold water undergoes secondary heat exchange with hot water, increasing the temperature of the hot water for subsequent processes and reducing the consumption of external heat sources. The optimization significantly improves the system's thermal efficiency, reduces energy consumption, enhances the stability of liquid chlorine gasification, effectively addresses issues in traditional systems, and provides a new approach to energy conservation and emission reduction in chlorinated paraffin production. This innovation is of great significance for promoting the green development of the industry.
