Optimization of C3 hydrogenation reactor and propylene tower system
With the rapid development of the global economy,the market demand for propylene is gradually increasing.In the actual production process,how to ensure the quality of propylene and improve the product output has caused much attention.In view of the phenomenons of low catalystactivity,failing to control the bedtemperature rise and unstability of the pressure and return flow of propylene towerin C3 hydrogenation reactor and propylene rectification tower system in ethylene plant,that resulted in large loss of propylene and fluctuations in the quality of propylene products,etc.Based on the previous operation experience,it optimized and adjusted the important process parameters,such as temperature and pressure of reactor bed,temperature difference between inlet and outlet of propylene tower reboilerduring the high load calibration of the plant,to achieve stable operation of the unit and increase propylene production.
