Cyclohexane Process Design

Co-developed a conceptual process design for a 40,000 MT/yr cyclohexane production facility and authored the technical report on methodology and assumptions.

Overview

Our senior design team needed to prove a cyclohexane production plant wasn't just technically feasible but actually buildable, so I helped design a process that hit 99%+ purity while clearing its own economic and safety hurdles.

The challenge

A process design only matters if it's buildable. Hitting purity targets in simulation isn't enough. The plant also had to clear its own economic hurdle rate, hold up under a formal hazard analysis, and account for its environmental footprint. All of this had to be grounded in real thermodynamics and reaction kinetics, not simplified assumptions.

What I did

  1. 1

    Researched the chemistry

    Studied the reaction mechanism and thermodynamic properties behind benzene hydrogenation to support the team's kinetic modeling.

  2. 2

    Built equipment specifications

    Documented equipment tables and specifications for the reactor and separation train.

  3. 3

    Modeled environmental and release scenarios

    Ran worst-case chemical release modeling using ALOHA and MARPLOT to support the plant's environmental and safety case.

  4. 4

    Contributed to the safety analysis

    Supported the HAZOP and safety review process for the plant design.

  5. 5

    Contributed to reporting

    Helped write weekly progress reports and sections of the final technical report covering methodology, chemistry, and assumptions behind the design.

  6. 6

    Presented the work

    Presented findings in weekly team meetings, the end-of-year presentation, and a poster presentation.
