WE DIDN’T CLEAN UP THE OLD PROCESS…
WE REWIRED IT.

0 ppm NOx (oxygen-fed). <1 ppb SOx emissions (in-process). 100s-1000s tons/day sulfuric acid. HP/MP Steam co-production.

WHAT SETS RECALIBRATE APART

We rebuilt the process so clean operation is a core feature. Oxygen replaces air. Nitrogen is out. No NOx. Proprietary SOx conversion and catalysts push SOx to near zero.

Zero NOx, by design

Near-zero SOx

Scalable 100Mt → 1,000 Mt

Proprietary Catalyst

Perspective: there’s more sulfur produced in a baby’s diaper than our annual emissions.

OLD WAY VS NEW WAY

A direct, operational comparison between legacy, air‑fed systems and Recalibrate’s oxygen‑fed architecture.

  • Air-fed process → NOx
  • SOx controls bolted on
  • High emissions stack
  • Complex management with many reactors
  • Oxygen-fed → 0 ppm NOx
  • SOx <1 g/ton acid produced
  • Compact, low-profile stack
  • Simple reactors enabling better management
