BLUE HYDROGEN OVERVIEW

The overview introduces the Blue Hydrogen Production Process and provides a safety briefing on the hazards associated with Blue Hydrogen Production.

MODULE 1: PRETREATMENT

Inorganic sulfur-bearing contaminants are removed and passed to an off-plot Sulfur Recovery & Tail Gas Treating Plant. Organic sulfur contaminants are removed by hydrotreating.

MODULE 2: STEAM REFORMING

Sweetened natural gas and superheated high pressure steam are reacted over a catalyst at high temperature to produce a mix of synthesis gases. The furnace fires a mix of sweetened natural gas and waste gas from the PSA Unit.

MODULE 3: SHIFT CONVERSION

The reactions started in the Steam Reformer Furnace are continued at progressively lower temperatures, producing more synthesis gas.

MODULE 4: PURIFICATION & COMPRESSION

The synthesis gas is passed through a PSA Unit to separate out pure near-hydrogen, which is then treated to remove mercury and any remaining traces of carbon oxides, before being compressed and exported to users via a pipeline. PSA waste gas is used as a secondary fuel in the Reformer Furnace.

MODULE 5: CARBON DIOXIDE CAPTURE & EXPORT

Carbon dioxide, recovered from natural gas combustion and synthesis gas adsorption operations is captured by flue gas water-washing and amine absorption. The captured carbon dioxide is compressed and sent to a geologic basin for sequestration.
