| Abstract: | The lubricant hydro-deacidification process was simulated,and the heat exchanger network of the process was analyzed,too.Based on pinch analysis principles,two unreasonable matches were found out.According to the pinch analysis principle totally,a retrofit scheme was proposed.It was pointed out that the high-temperature heat of the reaction oil and the high pressure separation gas could be fully utilized.The heater load decreased to 61.8%,and the cooler load was 84.5%.In addition,the energy efficiency of the system increased.Good results and considerable economic benefits were obtained. |
