ABSTRACT

The purpose of this thesis is to perform research and analysis on mechanical system

used in oil and gas industry. To reduce the scope of this thesis, a research and

analyses to improve mechanical seal is conducted. A mechanical seal is an important

component of variety of pumps used in chemical, petrochemical and process

industry. The primary function of a mechanical seal is to prevent leakage of the

process fluid from the pump housing and shaft to the environment. The factors that

affect the performance of a mechanical seal to leak are friction, wear and its thermal

characteristics. A new design of a mechanical seal with an implanted heat exchanger

in its mating ring is reported. The mating ring incorporates an internal channel in

which a coolant (either a gas or a liquid) flows to remove heat from the seal face. A

design was built and tested using CA TIA, SOLID WORK and ANSYS CFX .. Results

are indicative of effective cooling and improved performance when compared to a

conventional seal. A coating on the mating ring was successfully implemented. A

simplified heat transfer analysis using the results of the finite element method is also

presented for all the seal designs.
