Study of Dehydration of Coal-Oil Concentrate

Abstract

The article concerns the enrichment and dehydration of coal, namely the development of technology for selective oil agglomeration of fine and fine coal. The work is devoted to the study of technological properties of coal-oil concentrate as an object of dewatering. In particular, the dewater ability of coal oil aggregates of individual structural types was studied on sedimentation and filter centrifuges, drainage, on sieves - an arc sieve, a vibrating screen, a mesh conveyor, in vacuum filters, special methods: the method of mechanical disruption and water. auxiliary method of reinforcing coal-oil aggregates with finely dispersed coal. Based on the research results, recommendations were developed for the use of the studied equipment and technologies for dewatering coal-oil aggregates depending on their structural type.
