METHOD erosion and DELETE FROM SEDIMENTS vertical steel tanks with petroleum or petroleum products

摘要

1. A method for erosion and removal of sediments from vertical steel tanks with the oil and / or oil by means of the stationary erosion system including pipework, blurry provided with nozzles comprising filling the container with oil to a level that ensures safe operation of the system of erosion and erosion by bottom sediments supplying oil through the nozzle erosion pumping system from a reservoir diffuse sediment in the mixture with the oil, characterized in that the minimum oil level before the start of apolneniya reservoir through erosion ensuring safe operation system set in the range of 2-3 m, the injection flow rate of oil through the system is set not less than 200 m / p.2. A method according to claim 1, characterized in that the erosion and removal of sediments is performed before output of the tank ekspluatatsii.3. A method according to claim 1, characterized in that the pumping out from the tank bottom sediments diffuse in admixture with oil is carried out simultaneously with the filling of the reservoir through the oil razmyva.4 system. A method according to claim 1, characterized in that the pumping out from the tank produce stripping pumps to the minimum possible process urovnya.5. A method according to claim 1, characterized in that the tank filling operation oil to a level that ensures safe operation washout system sediment erosion by supplying oil through the nozzle and erosion of the pumping system from a reservoir posledovatelno.6 operate. A method according to claim 1, characterized in that the minimum oil level that ensures safe operation of the system for vertical steel tank with a fixed roof mounted on uro
