METHOD OF BURIAL OF INDUSTRIAL WASTES IN UNDERGROUND SALT CHAMBER THROUGH WELLS PROVIDED WITH PIPELINES Russian patent published in 1997 - IPC

FIELD: technology of burial of industrial wastes in underground salt chambers; applicable, for instance, in burial of waste of chemical production in workings formed by underground dissolving of rock salt beds. SUBSTANCE: the essence of the offered method consists in supply through pipeline to the lower part of the chamber of wastes with density exceeding the density of displaced brine by separate portions whose volume is 10-21 times as low as chamber volume free of insoluble fragments. In so doing, wastes are supplied in continuous stream at constant productivity evaluated by Richardson's criterion, whose value shall be within 0.1-1.8. Brine lifting column is installed so that distance between the bottom of brine lifting column and chamber ceiling shall not exceed 2.0 m. EFFECT: higher efficiency.
