Qazi Nasir
PhD — Researcher in CO₂ Capture & Process Modeling
Empowering innovation in chemical engineering through advanced research, teaching, and real-world problem-solving. With expertise spanning thermodynamics, gas hydrates, process simulation, and AI-driven optimization, I develop solutions that push scientific and industrial boundaries. Dedicated to impactful research, quality education, and knowledge that drives progress.
About
A researcher building bridges between thermodynamics and applied process engineering.
I am a chemical engineer and academic with a PhD from Universiti Teknologi PETRONAS and over eighteen years spanning university teaching, externally funded research, and industrial process engineering. My work centers on the thermodynamic and phase behavior of fluids and clathrate gas hydrates — particularly for CO₂-rich gas mixtures relevant to carbon capture and natural-gas processing.
As an Assistant Professor at the University of Nizwa, Oman and earlier at NUST, Pakistan, I taught thermodynamics, catalysis, and process simulation while leading research on hydrate equilibria, alkanolamine-based CO₂ capture, and heterogeneous catalysis — published in journals such as the Journal of Natural Gas Science & Engineering and Journal of Chemical & Engineering Data.
Today, as an independent researcher, I focus on AI-driven prediction systems for hydrate equilibria and clean-energy process modeling, alongside STEM education in Virginia — continuing to translate fundamental science into industrially useful tools.

Research
Four areas where I focus my work.
From fundamental phase behavior to deployed machine-learning models, my research targets the capture and processing of CO₂-rich gas systems.
Carbon Capture & Decarbonization
Hybrid membrane-absorption processes and alkanolamine systems for energy-efficient CO₂ separation from high-CO₂ natural gas, with semi-empirical equilibrium modeling.
Process Simulation
Steady-state and dynamic modeling of chemical processes — separations, reactors, and flow systems — using Aspen HYSYS and Aspen Plus for design and optimization.
AI-Driven Prediction Systems
Machine-learning and multi-layer perceptron neural networks that predict hydrate equilibrium conditions in multicomponent hydrocarbon systems — replacing costly experiments with fast surrogates.
