Abstract

This study concentrates on the design and construction of a laboratory-scale centrifuge for the separation of gum from crude palm oil (CPO). The extraction of gum from CPO is essential in the palm oil sector to guarantee that the finished product adheres to quality standards and is safe for consumption. We engineered the prototype centrifuge to accommodate six 600-mL bottles and achieve a maximum rotational speed of 1400 rpm. The design procedure utilised Autodesk Inventor software for CAD modelling and computations to ascertain the centrifugal force, power capacity, and shaft diameter. The process of manufacturing entailed cutting and shaping stainless steel into the necessary components, subsequently followed by drilling and milling operations for mounting points and interfaces. We implemented surface treatment to augment corrosion resistance and elevate visual appeal. The assembling procedure encompassed component integration, motor incorporation, and control system configuration. The experimental configuration involved centrifugal testing utilising 600-mL glass bottles with time intervals of 10, 20, 30, and 40 minutes at an average rotational speed of 924 rpm. The experiment showed that the centrifuge worked well to separate the gum and other contaminants from the CPO. The best separation happened after 40 minutes of centrifugation.

Abstract

This research examines the effect of bricks enhancement with phase change material (PCM) consisting of paraffin on their thermal considerations. The experimental methods were aimed at investigating the mechanisms of temperature transfer throughout the thermal rounds, mimicking diurnal fluctuations of temperature. Due to the high amount of latent heat contained in paraffin a portion of it was transferred into regular bricks with temperature probes tracing the heat processes. It is shown that enhancement of bricks with PCM reduced temperature range and controlled the rate of heat transmission more than the ordinary bricks did. It was significant that the PCM-embedded bricks did not drift in heat and were able to stock up excess heat during the day and release it at night which resulted in monumental energy efficiency and comfort in thermal standing. The conversation additionally seeks to bring out the function of paraffin in insulation which does not only save energy consumption but goes forward to maintain comfortable temperatures within the building. The study finally achieved its goal and assert that energy saving with the use of PCM enhanced bricks in construction makes it a preferable material in regards to energy and the fight against climate change.

Abstract

Hydrogen gas is one of the alternative fuels that is currently being widely researched. HHO generator is a tool with the working principle of water electrolysis and is used to produce hydrogen gas. In some studies, peat water has been considered to be used as an electrolyte. This research uses experimental methods to obtain hydrogen gas results from peat water electrolysis. The electrolysis reactor used can handle as much as 400 ml of peat water. The electrodes are stainless steel (SS) with a large cross-sectional area of 0.01884 m2. The electric power used was 12 Volts DC and the time in the electrolysis process was 1 minute. Based on the results of the research that has been done, among others, where the increase in HC in the exhaust gas in Aquades water looks very efficient at the initial rotation at 2000 rpm which produces a thermal efficiency of 60% While in peat water the increase in HC in the exhaust gas in Aquades water looks very efficient at the initial rotation at 2000 rpm which produces a thermal efficiency of 90%. The influence of rpm and the unstable rotation of rpm causes the CO value in the exhaust gas of the vehicle to be unstable where at low rotation readings 223. 24 ppm, middle 634.94 ppm and top 606.89 ppm, it can be seen that in the upper round the value even decreases from the middle round, while in HHO peat water when the low round reading is 104.4 ppm, middle 101.94 ppm and top 121.29 ppm, it can be seen that in the upper round the value increases from the initial round to the top.
