This pumped phosphoric acid removes the heat of reaction by being circulated through a heat exchanger and provides the water for phosphoric acid formation. The acid produced is extracted from the pumped phosphoric acid. Phosphoric acid mist in the tail gases (6 to 8 of residual oxygen) is removed before venting for example by venturi scrubbers.
