3. Department of Chemical Engineering, BMSCE 3 INTRODUCTION Natural gas is a naturally occurring mixture of gaseous hydrocarbons consisting primarily of methane ( 85-90% ) in addition to various smaller amounts of other higher alkanes. Turning natural gas into LNG reduces its volume, making it practical for global shipping, storage, and diverse applications.

4. Department of Chemical Engineering, BMSCE 4 INTRODUCTION In this process, a shell and tube exchangers are used to cool methane vapour using water as the cool fluid. A shell and tube heat exchanger is one of the most popular types of exchangers due to its flexibility. In this type, there are two fluids with different temperatures, one of them flow through tubes (water) and another flow-through shell (methane vapour). Heat is transferred from one fluid to another through the tube walls, from the shell side to the tube side.

5. Department of Chemical Engineering, BMSCE 5 AIM: Design of shell and tube heat exchanger for the Liquefaction of natural gas. OBJECTIVES: Dimensional Analysis utilizing data from Perry’s Handbook and IS Codebook Mechanical design is carried out where in thickness of shell, number and diameter of tie rods are detmined.

It describes the procedure followed for creating and evaluating different models, the calculation of pressures and mass flow, enthalpies calculation, solution relaxation, flash call for finding temperature, vapor fraction, and heat flow, as well as the time step function.

7. LITERATURE SURVEY-01 Department of Chemical Engineering, BMSCE 7 The use of heat transfer correlations for single-phase turbulent flow in a pipe, and the correlations for two-phase flow such as evaporation and condensation. Pressure drop modeling is also discussed, including the Homogeneous Equilibrium Model (HEM) and Separated Flow Model (SFM), as well as the determination of pressure drop in single-phase flow. The paper then delves into the development of numerical models for both single-phase and two-phase heat exchanger.

The Design and Optimization of Natural Gas Liquefaction Processes: A Review. Energies , 15 (21), 7895. https://doi.org/10.3390/en15217895 It mentions the importance of conducting comparative analyses of refrigerant proportioning content in LNG processes to optimize efficiency and operational characteristics. The importance of safety analysis in LNG processes, including issues related to LNG leakage, heavy hydrocarbons recovery, and safety considerations for floating LNG (FLNG) units.

JJMIE -Jordan Journal of Mechanical and Industrial Engineering , Volume 12 Number 2, September. 2018 Pages 109-116 (ISSN 1995-6665). The initial design procedure for the heat exchangers in the text is based on an analytical approach using the Kern method This method involves several steps, including finding the required thermophysical properties of hot and cold fluids, performing energy balance calculations to determine the heat duty, and assuming a reasonable value for the overall heat transfer coefficient.
