SYSTEM FOR ANALYZING FLUID VELOCITY IN HEAT EXCHANGER

Fouling of heat exchanger is concerned by industry especially in oil and gas industry. Slugs and rust in the heat exchanger will limit the flow of fluid in the pipeline and reduce the diffusion capability. Hence, affect the heat exchanger efficiency. Cleaning process will halt the refinery from going on and it will result in major cost penalties. Therefore, the best timing to perform the cleaning and maintenance process must be determined to avoid unnecessary cleaning by measuring the fluid velocity and the heat transfer coefficient. The objectives of this project is to design and build a system for monitoring the flow rate and temperature of flowing fluid in the heat exchanger and to design a computerized system to monitor the performance of heat exchanger. Experiments are conducted using distilled water and water containing 10% and 20% of soil. The result gained is analysed and the best timing to perform the cleaning process is determined. The objectives of this project are met and the project is successful.
