Arsenic (As) removal
Natural gas · groundwater
Also called: arsine, trialkylarsines
How it is removed
Chemical impregnation converts soluble arsenates to insoluble forms which adsorb into the pore structure.
Recommended grade
The specification that decides it Removal efficiency — 99% min at 2–2.5 ppm inlet, <1 ppb outlet
Test against your own duty
Capacity depends on inlet concentration, temperature, humidity, contact time and
competing species. Nothing here is an assurance that a grade will perform in your
service — it is a starting point for a trial.
Trial batches run from 1 to 10 tonnes.
