Sulfuric acid is used as a key first step in the production of both MAP and DAP, after which it is mixed with phosphate rock to produce phosphoric acid. And since the phosphoric acid production process consumes energy, an on-site sulfuric acid plant – a net producer of energy – is a critical part of the fertilizer production process.
