Abstract

Temperature is a measure or degree of hotness or coldness of an object or system which is defined as a physical quantity that is divided between two or more objects that are in thermal equilibrium. The second law of thermodynamics states that there is no reversible process in which heat flows naturally from a high-temperature object to a low-temperature object, and not vice versa. Heat is energy that is transferred due to a temperature difference. This heat transfer always occurs and the process stops until thermal equilibrium occurs. In a high temperature distillation column, the distillate fluid will tend to be at the top and the bottom will tend to be cooler even though the heat treatment is carried out at the bottom. Thermal equilibrium is reached in a relatively long time because the distillation system is open. The addition of the pump aims to reconstruct the temperature so that it reaches thermal equilibrium more quickly. The process is carried out for 60 minutes using 25 liters of raw materials of the same quality and the temperature is set at 90 degrees Celsius. The average temperature difference in the reactor is 86.11%, the decrease in fuel consumption is 30.3%, and the increase in distillation quantity between the reactor without a pump compared to the reactor with a pump is 16.67%.

Abstract

Distillation is the process of separating two or more components of a liquid based on their boiling points in which the material to be evaporated is contained. Distillation is simply done by heating/evaporating the liquid and then changing the vapor phase to liquid with the help of a condenser. Research on the distillation column or reactor has been carried out to improve the distillation system but is still discussing the reactions that occur due to heating and the final product of the distillation process. An analysis based on the second law of thermodynamics is developed, known as exergy analysis to obtain information about the thermodynamic efficiency and locations that have low energy efficiency so that energy savings can be targeted. The distillation reactor as one of the vital tools at the separation stage is very important to note is the manufacture of the reactor. To reduce heat loss that occurs by adding a heat protective layer (heat cover) on the distillation reactor. The heat protection materials used are burlap sacks and glass wool to be implemented for rural communities and also become prototypes of appropriate technology application tools. The use of a 3 cm jute alloy on the inside and 3 cm glass wool on the outside gave the highest heat transfer value of 7864.21 watts. The increase was 43% of those who only used burlap. An increase of 37% over those using only glass wool. A 3% improvement over an alloy of 3 cm glass wool inside and 3 cm burlap on the outside.
