How it is removed
Acid impregnation neutralizes the basic gas and stores the reaction product in the pores. Virgin carbon has almost no ammonia capacity — impregnation is mandatory, not optional.

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.
