Abstract
The field practice took place at the Central Luzon State University-Center for Renewable Energy and Technology (CLSU-CREaTe), Science City of Muñoz, Nueva Ecija. It occurred from October to December 2023 and from March to May 2023.
The objective of Field Practice Activity 1 was to evaluate the operation of a 250L semi-automated bioreactor utilizing both AC and solar power. The main goals of this activity were to: 1) evaluate a semi-automated bioreactor using both AC and solar power sources; 2) determine the fermentation efficiency of the semi-automated bioreactor using both AC and solar power sources; and 3) compare the power consumption between the AC and solar power sources.
The objective of field practice Activity 2 was to design a bioethanol distiller with a tank capacity of 800 liters. The main goals of this activity were to: 1) ascertain the most favorable dimensions (area and height) for an 800L tank capacity bioethanol distiller; 2) identify the additional components required for the bioethanol distiller; 3) create a design layout for the bioethanol distiller; and 4) compile a bill of materials for the bioethanol distiller.
The objective of field practice activity 3 was to carry out more tasks. The primary aims of this activity were to : 1) carry out additional tasks as directed by the center director, student-trainee supervisor or any CLSU-CREaTe staff; and 2) enhance the students' performance preparedness and adaptability in their chosen fields of expertise.
An evaluation was conducted on the fermentation efficiency of the 250L semi-automated bioreactor, utilizing both AC and solar power sources. The results demonstrated a fermentation efficiency of 81.7% and 83.5% correspondingly. The AC supply consumed 6.25 pesos, while solar power saved more but was more expensive in terms of initial cost. Solar power delivers economic savings in the long run and environmental benefits, making it an attractive alternative for numerous applications.
The bioethanol distiller's design, which holds a capacity of 800L, has been adjusted to a bigger size. The design contains a tank, reflux column, primary condenser, slanted secondary condenser, vertical secondary condenser and frame. The final dimensions were computed to assure the machine's efficiency and durability. Moreover, the student-trainee acquired knowledge with numerous areas of renewable energy, including participation in events, executing machine evaluation tests, and partaking in equipment installation during field practice time frame.
