Hydrogen Separation Using Liquid Contact TRIZ Cases

Partial oxidation of sulfur vapor in a Claus-type furnace enables co-production of hydrogen and sulfuric acid with controlled reaction temperatures.

Sub-stoichiometric sulfur oxidation stabilizes sulfur monoxide, enabling hydrogen generation and sulfuric acid co-production in one furnace train.

Using syngas heat for feed preheating and steam generation removes the fired heater and concentrates CO2 in a high-pressure stream for capture.

This case combines condensate recycling, water-gas shift stages, and CO2 scrubbing to produce hydrogen while reducing emissions.
