ABSTRACT:
A method for collecting a solid product from a liquid phase or liquid phase-gaseous phase feed stock. A solid forming zone is provided for accommodating the liquid phase or liquid phase-gaseous phase feed stock having a density greater than that of a liquid to be fed. A precipitation zone is provided at its lower portion with a feed port for feeding the liquid and a discharge port for taking out the solid product and communicating with the solid forming zone at its upper portion. The precipitation zone is provided therein with stirring means by which the solid product and liquid are contacted with each other countercurrently. The solid product is washed with the liquid and the density relation between the liquid phase and the liquid is reversed as the latter moves upwardly in the precipitation zone. Solid oxamide may be produced from cyanogen.
