Ammonium Sulfate products – Martin Midstream Partners

The conventional caprolactam process produces 2.5 - 4.5 tons of ammonium sulfate per ton of lactam. Of that, 0.3 - 2.8 tons are formed in the hydroxylamine - oximation stage and approx. 1.7 tons in the Beckmann rearrangement stage. Crystallizers are used in the evaporation of ammonium sulfate solutions that result from caprolactam production.

Uses. The primary use of ammonium sulfate is as a fertilizer for alkaline soils.In the soil the ammonium ion is released and forms a small amount of acid, lowering the pH balance of the soil, while contributing essential nitrogen for plant growth. The main disadvantage to the use of ammonium sulfate is its low nitrogen content relative to ammonium nitrate, which elevates …
