Design of Oil-Free Compressor in Compressed Air System PT Sanbe Farma Unit 1

Abstract

This research is the development of a screw type compressor technology found in the utility system of PT. Sanbe Farma. This design aims to design a screw oil-free compressor focusing on solving problems that generally occur in a compressor, namely contamination between compressed air and oil. For this compressor, ISO Standard 8573-1: 2010 is used, and then the design results are compared with the simulation results that have been validated using the Aspen Hysys application. Several factors can affect the compressor's design, including the use of diameters in the pipe installation and the selection of the motor used to meet the demand for compressed air. The results of the theoretical design (simulation of Aspen Hysys software) show close values, so design is proven accurate and appropriate and can be applied. With a compressed air requirement of 0.0063 m3/s and a pressure of 8 bar, a compressor power of 72.7 kW and a motor power of 103 kW are required.
