I designed a full shell-and-tube heat exchanger using mechanical design practices and heat-transfer principles.
Method
Modeled the shell, tube bundle, tube sheets, baffles, channel heads, flanges, and nozzles.
Patterned the tube bundle with equally spaced segmental baffles to improve shell-side flow.
Assembled and constrained every component into a realistic industrial assembly with labeled parts and dimensions.

Biodiesel Production and Operations
Personal project | MATLAB | January 2025
Prepared the feed. Used MATLAB to calculate reactant quantities for 3 L of used cooking oil, then measured 600 mL of methanol and 10.5 g of sodium hydroxide catalyst to make the methoxide solution.
Ran the reaction. Converted triglycerides in the oil into biodiesel through transesterification, with glycerol as the byproduct.
Separated the product. Let the mixture settle and drew off the heavier glycerol phase from the biodiesel layer.
Applied material balances, stoichiometry, phase separation, and process-operation principles that carry over to refining and fuel production.
Natural Gas Chiller Plant Simulation
Academic project | AVEVA PRO/II | Cal Poly Pomona
Built a steady-state natural gas processing simulation through Chiller Plant Part 4, integrating compression, heat exchange, refrigeration, vapor–liquid separation, and a stabilizer column. Applied the Peng–Robinson thermodynamic method and configured a controller to calculate the mixed-refrigerant flow required to meet a specified gas outlet temperature.
