Abstract

Heat exchanger is an equipment that is widely used in industries such as power plant, food processing, oil and gas refinery and air conditioning. The function of heat exchanger is to facilitate exchange of heat between two fluids that are at different temperature while keeping them from mixing with each other. The biggest problem that occurs in all types of heat exchanger is fouling which can be classified as the number one critical issue in industrial application. Fouling is generally defined as the acquisition and formation of undesired materials on the surfaces of processing equipment. Due to these consequences, this study focused more on the invention of pigging device in spirit of controlling fouling problems. The main purpose of this study is to enhance the design and to test the performance ability of the device developed. The current design of the novel pigging device which known as brush and cage system, used to operate inside the pipe to clean the fouling. In order to meet the objectives of this study, the enhancement of Brush and Cage System design was conducted. Blades were applied to the tips of the brush in order to increase the effectiveness of the cleaning process by performing the rotation motion. Acrylic pipe was used to ease the observation process during the project testing. The results showed that the brush was able to flow because of sufficient pump capacity. However, no rotations were produced during the operation. This happened due to the design of the blades itself, which not able to create the rotation motion of the brush.
