Case Study : Hydrogen Production General Atomics, San Diego CA H 2 production utilizing Thermo-Chemical Sulfur-Iodine process Corrosive media: Hydroiodic (HI), Sulfuric acid (H 2 SO 4 ) and Phosphoric acid (H 3 PO 4 ) High temperature: Over 400C (752F) High pressure: 300 - 1250 psi (22-85 bar)

General Atomics, San Diego CA

H 2 production utilizing Thermo-Chemical Sulfur-Iodine process

Corrosive media: Hydroiodic (HI), Sulfuric acid (H 2 SO 4 ) and Phosphoric acid (H 3 PO 4 )

High temperature: Over 400C (752F)

High pressure: 300 - 1250 psi (22-85 bar)

Thermo-Chemical Process Section II : Sulfuric acid concentration and decomposition > 400C Section I : Acid recycle and generation of HI and H 2 SO 4 at 120C Section III : HI, H 3 PO 4 and H 2 O are decomposed (320C), separated and the acids re-concentrated at 260C Requires Very Strong Acids

Section II :

Sulfuric acid concentration and decomposition > 400C

Section I :

Acid recycle and generation of HI and H 2 SO 4 at 120C

Section III :

HI, H 3 PO 4 and H 2 O are decomposed (320C), separated and the acids re-concentrated at 260C

Case Study: Hydrogen Production Problem Extremely corrosive mixture of H 2 SO 4 + HI and H 3 PO 4 HI is the strongest halide acid Most corrosive conditions 80 wt% H 3 PO 4 , 8 wt% HI, 12 wt% H2O up to 280C at 150 psi 96-100 wt% H 3 PO 4 at 240-260C Ni alloys, Ti, Zr are unsuccessful Usable materials: Glass / Ceramics / Tantalum Glass & ceramics have limited pressure range Even solid tantalum is failing due to hydrogen embrittlement

Problem

Extremely corrosive mixture of H 2 SO 4 + HI and H 3 PO 4

HI is the strongest halide acid

Most corrosive conditions

80 wt% H 3 PO 4 , 8 wt% HI, 12 wt% H2O up to 280C at 150 psi

96-100 wt% H 3 PO 4 at 240-260C

Ni alloys, Ti, Zr are unsuccessful

Usable materials: Glass / Ceramics / Tantalum

Glass & ceramics have limited pressure range

Even solid tantalum is failing due to hydrogen embrittlement

Case Study: Hydrogen Production Solution (over past 3 years) Installed hundreds of Tantaline treated Swagelok® fittings Installed dozens of ball and needle valves Replaced solid tantalum parts with Tantaline solutions Results No Tantaline failures to date, making process technically feasible Tantaline products have shown to resist hydrogen embrittlement, lasting many times long than solid tantalum Because parts are not failing the process is safer Tantaline made General Atomics process to economically feasible “ Without Tantaline our process would not be possible” Ben Russ – Staff Engineer

Solution (over past 3 years)

Installed hundreds of Tantaline treated Swagelok® fittings

Installed dozens of ball and needle valves

Replaced solid tantalum parts with Tantaline solutions

Results

No Tantaline failures to date, making process technically feasible

Tantaline products have shown to resist hydrogen embrittlement, lasting many times long than solid tantalum

Because parts are not failing the process is safer

Tantaline made General Atomics process to economically feasible

“ Without Tantaline our process would not be possible”
