Design of Cooling System for Low-temperature Drying Unit Designed for Treatment of Mined Natural Gas

Abstract

This master’s thesis deals with the design of a cooling system for a low temperature drying unit for the treatment of natural gas. The theoretical part presents information about principles of natural gas, refrigeration cycles and heat exchangers. The practical part describes the methods and calculations to design the cooling system unit, selection of the compressor and thermal expansion valve, design of evaporator and design of condenser by comparing the use of refrigerant R404A and R449A. Lastly, it is shown the specified technical parameters and technical drawings.
