Acetone Removal from Air by Water Absorption with Solvent Recovery

This simulation demonstrates the removal of acetone from an air stream using water as the absorbent. The gas is first cooled before entering the absorber, where it contacts water counter-currently. Acetone transfers from the gas into the water, producing a cleaner gas stream and an acetone-rich liquid stream. The rich liquid is then heated and sent to a flash drum to recover part of the acetone as an acetone-enriched vapor. The simulation brings together cooling, gas absorption, heating, and flash separation in one process and shows how changes in operating conditions affect the overall separation.

Flare Gas to LPG ( NSCHE Training)

I used this simulation to train students from the NSChE National Student Chapter on process simulation. We worked through how flare gas can be processed into LPG and discussed why we need each equipment along the way — from compression and cooling to separation and distillation. The goal was simple: don't just learn how to run a simulation. Understand the process and think like a process engineer.

Graphite Purification via Multi-Stage Acid Leaching

This flowsheet models the purification of natural graphite through sequential acid leaching to remove metallic impurities. The solid feed contains 95 wt% graphite with SiO₂, Fe, Al, Mg and Ti impurities at a P80 of approximately 150 µm. A mixed H₂SO₄–HNO₃–HCl leaching system is evaluated at an initial operating temperature of 40°C. The flowsheet uses staged leaching to represent the removal of Fe, Al, Mg and Ti, producing a purified graphite solid stream and a metal-containing pregnant leach solution. Objective: establish a baseline mass-balance model and ultimately determine the acid composition and operating temperature that maximize impurity removal and final graphite purity. Current status: Baseline model developed and converged. Next step is validation against experimental/literature data followed by sensitivity analysis and optimization.
