F.S. Elliott is a global leader in the engineering and manufacturing of centrifugal compressors, with operations in over 90 countries. The company has over 50 years of service and has built a reputation as a friendly and reliable manufacturer. At present, the high-speed direct-drive compressor is a new technique and F.S Elliott is experimenting with new ideas to adopt this recent technology. An air compressor efficiently converts the energy utilizing a series of stages to compress and cool the air as it continuously flows through the unit. Traditionally, turbine oil is used as a lubricant in a centrifugal compressor. This project is to research the possibility of replacing turbine oil with glycol. Generally, glycol is a chemical typically used in cooling systems for automobiles and air conditioning systems. However, if glycol can be further used as lubricant, it can greatly benefit a high speed direct-drive compressor. The advantages may include an easier internationally shipping experience, more environmentally friendly, and connecting and integrating the cooling and lubricating systems within a compressor to simplify the system design. This project analyzes and compares the chemical and physical properties of turbine oil and glycol, to optimize the compositions of and conditions for such replacement, and decide the cost and feasibility of the replacement.
