35+ Years of Dedication

Over 35 years of continuous, focused dedication and refinement — distilling the most effective principles and methodologies from the full body of reactor engineering knowledge into this package.

Crafted Through Practice, Teaching & Industry

Shaped by teaching in 17+ roles across universities, engineering firms and technology companies — incorporating a wide variety of instructions and insights from across the industry spectrum.

Learned from Challenges & Successes

Every methodology has been stress-tested against real-world challenges and refined through many documented successes — both of which are irreplaceable teachers in reactor engineering.

Designed & Deployable Anywhere

Can be designed almost immediately and built or delivered in any living environment — Shipboard, Well-mouth, remote, mine-mouth and more — and operated by almost anyone, anywhere.

Constant Validation at Every Phase

Each part validated at all phases — including successful commercialization of 4 new technologies and numerous projects at conceptual design, testing and demonstration stages.

Hands-On Design, Development & Fabrication

Direct hands-on involvement in design, development, fabrication, catalyst preparation and lab-scale unit construction — grounding everything in physical reality, not just theory.

Simultaneous Programming & Modeling

All hands-on work conducted in parallel with programming and coding — building robust, integrated modeling and design tools from the ground up, with every physical insight matched to a computational tool.

Validation by Lab & Commercial Plant Data

Results and models rigorously validated against both laboratory data and real commercial plant operating data — ensuring full reliability at every scale from bench to industrial plant.

Combined CRE + PSE — Inspired by & Dedicated to the Pioneers

Rooted in Chemical Reaction Engineering (CRE) + Particulate Systems Engineering (PSE), inspired by the two pioneers in the fields — Octave Levenspiel (OL) and Daizo Kunii (DK). One pioneer (OL) directly encouraged this work through a personal note to build such a package. This entire package is dedicated to their memory and legacy.

Fluidized Beds, Packed & Particulate Solids, Solids Circulation

Special deep expertise in Fluidized Bed and Packed vs. Particulate Solids Characteristics and Solids Circulation Systems — some of the most complex and industrially critical reactor configurations — ensuring the package handles these demanding systems with complete technical depth and confidence.

TECH SUITE — Investor & EPC Overview

"Most process software helps engineers find a design that works. Tech Suite helps them find the best design — and clearly shows why it's better. That difference sounds small, but in reactor engineering, it completely changes how decisions get made."

Positioning — What TECH SUITE Is and Is Not

TECH SUITE IS NOT TECH SUITE IS
X One massive, all-in-one software package that tries to do everything ✓ A decision-intelligence engine for chemical processes
X A general-purpose simulator that handles every type of process ✓ A tool that helps teams evaluate designs more holistically
X A replacement for popular plant simulators. ✓ A complement — showing not just if a design works, but why it's better
X Designed to replace engineers or specialist expertise ✓ A tool that makes reactor design structured, repeatable, and faster

Frequently Asked Questions

Most simulators treat reactors like special cases — something that needs an expert to carefully tune, adjust, and validate. So what happens in reality? Engineers usually stop once they find the first feasible solution. Not the optimal one — just the first one that works.

Tech Suite changes that. We treat reactors as standard unit operations. The software automatically explores multiple design pathways — different configurations, operating windows, constraints — and compares them objectively so the team can make the right decision, not just the first one.

Process engineers, chemists, EPC technical leads, and R&D teams.

But more importantly — it reduces dependence on a handful of specialists. Right now, high-quality reactor design often depends on one or two senior experts in a company. That is hard to scale.

Tech Suite makes high-level reactor design structured, repeatable, and accessible to broader teams — without compromising technical depth.

Typically we license it at the enterprise level, and we also offer project-based licensing for companies that want to use it on a specific engineering job.

In many cases, a single project can justify the cost. If the tool helps avoid overdesign, unnecessary capital spending, or a failed scale-up, the savings from that one decision can easily outweigh the license fee.

It really comes from years of accumulated engineering experience. This wasn't originally built as a commercial product — it started as a way to solve real reactor design challenges.

Over time, as more capabilities were added and the approach proved useful across different problems, it became clear that it could evolve into a broader platform others could use.
