Fixed-Bed Antimicrobial Reactor for Wastewater Disinfection

Reactor DesignCatalyst ImmobilizationKineticsCharacterization
The Problem

Conventional wastewater disinfection methods produce toxic by-products and struggle with emerging pathogens. A stable, reusable antimicrobial system was needed for continuous-flow operation.

What I Did
Synthesized nAg/Kaolin composite via spray deposition and 10-step annealing protocol onto borosilicate glass beads
Designed and built custom continuous-flow fixed-bed reactor
Ran structured experimental campaigns across 288-hour reusability tests
Derived first-order disinfection kinetics using plate cell counting (LB-agar)
Characterized using Raman, TEM-EDX, and FIB-SEM
Outcomes
<2 hrs complete disinfection
kd = 2.56–2.76 cm h⁻¹
288 hrs full reusability
Intact silver integrity post-use

H₂S-to-Hydrogen Process Design & Techno-Economic Assessment

Aspen PlusTEAScale-UpGas Processing
The Problem

Sour natural gas streams containing H₂S are a safety and environmental liability. Converting H₂S to hydrogen offers both economic value and environmental benefit — but requires rigorous process modeling and cost justification.

What I Did
Built full Aspen Plus steady-state process model for H₂S photocatalytic conversion via NaOH absorption
Performed Pre-FEED level TEA with complete CAPEX/OPEX breakdown and equipment sizing
Conducted sensitivity analysis on feedstock cost, product price, and conversion efficiency
Identified scale-up constraints and retrofit feasibility for existing gas-processing plants
Ran parametric optimization using gPROMS coupled PDE/ODE modeling
Outcomes
+10% process feasibility improvement
Retrofit strategy for existing infrastructure
Reduced corrosion risk
Full TEA investor-ready package
