| Abstract: | The production process of 120 kt/a DAP, due to design flaws exhaust gas cleaning and dust removal system, long-term existence of dust and ammonia spillover problem seriously, short production cycle. Through the transformation of the system; The granulation and drying gas wash separately, carries on the adjustment to the part of the equipment size and levels of washing medium. Good results are achieved in the field of environmental improvement, ammonia recovery rate, production cycle extended. |
