METHOD OF CONTROL OF PROCESS OF OBTAINING LIQUID FERTILISER FROM THE MOTHER LIQUOR Russian patent published in 2012 - IPC C05C3/00 C01C1/24 

FIELD: agriculture.

SUBSTANCE: method of control of process of obtaining liquid fertiliser from the mother liquor of ammonium sulfate by feeding the mother liquor of ammonium sulfate from the thickener into the pressure vessel with a flow sensor and a valve, comprising additionally the initial capacity of the mother liquor with the pipes, a pump for feeding liquid fertiliser with a filter, a circulation contour with pipelines including the pump for feeding liquid fertiliser - the filter - the initial capacity of the mother liquor - the pump for feeding liquid fertiliser - pH sensor of the liquid fertiliser, the flow sensor and the condensate valve, the flow sensor and ammonia water valve, the flow sensor and the valve of flow rate of liquid fertiliser and the valves of the circulation contour mounted on the pipelines; and the flow rate of the liquid fertiliser is given, the flow rate of condensate and the flow rate of the mother liquor, the pH index of the liquid fertiliser, and the valves of liquid fertiliser, condensate and ammonia water are affected.

EFFECT: invention enables to eliminate the loss of the mother liquor, to improve ecology of the environment, and to simplify the process of obtaining mineral fertiliser.
