Abstract

The condenser is a critical component in systems designed to condense steam into liquid. The performance of a condenser can be influenced by the rate of heat transfer, vacuum pressure, and effectiveness. The aim of this research is to ascertain the effectiveness value and the variables affecting the performance of the condenser in the distillation process of citronella leaves, as well as to understand the impact of the heat transfer rate on film condensation (condensate steam mass). The methodology for assessing effectiveness values utilized the Log Mean Temperature Difference (LMTD) and Effectiveness – Number of Transfer Unit (NTU) approaches, alongside comparing the condensate steam mass with the steam mass flow rate to achieve film condensation. The research findings revealed an effectiveness value of 89% for the condenser, with 36% of the condensate steam mass converting into bio-oil. Influential variables include a capacity ratio of 0.0182840 and a heat transfer rate of 186,544.68 W. The LMTD was calculated to be 29.74°C. Thus, it can be concluded that the condenser used in the distillation process of citronella leaves still maintains good performance.

Abstract

The condenser is one of the main components in a system that condenses vapor into liquid. The performance of a condenser can be influenced by heat transfer rate, vacuum pressure, and effectiveness. The aim of this research is to determine the effectiveness value and variables that affect the performance of the condenser in the lemongrass distillation process, as well as to understand the influence of heat transfer rate on film condensation (condensate vapor mass). The research method used the Log Mean Temperature Difference (LMTD) and Effectiveness - Number of Transfer Unit (NTU) to calculate the effectiveness value and compared the condensate vapor mass with the mass flow rate of vapor to obtain film condensation. The research results showed an effectiveness value of 89% in the condenser, and the condensate vapor mass accounted for 36% of the biooil. The influencing variables were a capacity ratio of 0.0182840, a heat transfer rate of 186544.68 W, and an LMTD of 29.74°C. Therefore, it can be concluded that the condenser used in the lemongrass distillation process still performs well.
