About VOx Envirotech

Our story

Founded in St. Louis, MO in 2016 and expanded through a Shanghai-based joint venture in 2017, VOx Envirotech brings together two industry veterans with decades of shared experience.

Prior to launching VOx, the founders established themselves as pioneers in chemical process and environmental technologies. Today, that combined expertise drives everything we build — from high-destruction thermal oxidation to closed-loop chemical recovery.

VOx is committed to building a clean, low-carbon, energy-efficient green world — and to developing and delivering the solutions and products that make it possible.

Pollution control

Clean air and water for demanding chemical processes.

Decarbonization

Low-carbon pathways that convert emissions into value.

Energy saving

Smarter power use for rotating equipment and beyond.

What we do

Solutions

Three complementary solutions. One integrated approach to cleaner, more efficient operations.

Pollution Control

  • Waste Incineration Thermal and catalytic oxidizers for high-destruction efficiency.
  • Exhaust Gas Treatment Hot gas quench, absorbers and scrubbers, dust and fine particulate collectors, and DeNOx (SCR/SNCR) tailored to your flue gas composition.
  • Integrated Pollution Control Combined treatment with energy and/or material recovery, maximizing resource efficiency and material reuse in chemical operations.

Decarbonization

  • Green Methanol Closed-loop solution for green methanol production and usage in maritime shipping.
  • Green Hydrogen + Oxy-Combustion Coupled solution of green hydrogen production and oxy-combustion process.
  • Liquid-Fuel Conversion Cost-effective distributed conversion of VOCs and biogas to liquid fuels.

Energy Saving

  • Permanent Magnet Adjustable Speed Drive (PM ASD) Reduces power consumption, vibration and maintenance of large rotating loads — such as fans, pumps and mixers — in harsh industrial environments.

Proprietary advantage

Core technologies

Engineered systems built on proprietary models and proven process design.

01

Intelligent Combustion Control

A deep-learning and thermodynamic hybrid model that instantly counteracts severe feed fluctuations (flow rate, calorific value), ensuring complete combustion within safe limits while maximizing energy savings.

02

High-Temperature Corrosive Quenching

Handles flue gas up to 1,300°C with corrosive agents (e.g., F, Cl) up to 20% by volume. Rapid quenching eliminates corrosion and fouling, with a turndown ratio of 0–120% and 12-fold reliability.

03

Closed-Loop Scrubbing & Regeneration

Recovers VOCs from tail gas and ammonia from wastewater, turning pollutants into valuable byproducts.

04

High-Efficiency SNCR DeNOx

Our proprietary atomization and airflow design achieves up to 90% DeNOx efficiency — far exceeding the conventional 30–70% range.

05

Single-Bed Chemical-Looping Reaction

Application for catalytic combustion, reverse water-gas shift, and ammonia synthesis.
