Abstract
1. Способ зачистки резервуара и утилизации нефтешламов, включающий подачу нефти в резервуар для разрушения и разбавления нефтешламов, отвод образующейся при этом смеси из резервуара, согласно изобретению указанную смесь выводят из нижней части резервуара, нагревают в теплообменнике до температуры плавления парафинов и возвращают в резервуар, распределяя над осадком в придонной части резервуара при помощи установленного над резервуаром распределителя потока, снабженного гибкими трубопроводами, причем смесь подвергают циркуляции по схеме «резервуар-теплообменник-распределитель потока» до достижения температуры кристаллизации смеси, не превышающей температуру окружающей среды. ! 2. Способ по п.1, отличающийся тем, что после нагрева смеси нефтешлама с нефтью от нее отделяют мехпримеси и воду. ! 3. Способ по п.1 или 2, отличающийся тем, что выведенную из резервуара смесь подвергают ультразвуковой обработке либо перед ее нагревом, либо после нагрева. ! 4. Способ по п.1 или 2, отличающийся тем, что перед ультразвуковой обработкой в смесь добавляют диспергатор парафинов и/или депрессорную присадку для снижения температуры кристаллизации. 1. A method of cleaning the tank and disposing of oil sludge, including supplying oil to the tank for the destruction and dilution of oil sludge, removing the resulting mixture from the tank, according to the invention, this mixture is removed from the bottom of the tank, heated in a heat exchanger to the melting point of paraffins and returned to the tank, distributing over the sediment in the bottom of the tank using a flow distributor installed above the tank, equipped with flexible piping, and the mixture is circulated with Birmingham "flow-exchanger tank-way valve" to achieve the crystallization temperature of the mixture not exceeding ambient temperature. ! 2. The method according to claim 1, characterized in that after heating the mixture of oil sludge with oil, solids and water are separated from it. ! 3. The method according to claim 1 or 2, characterized in that the mixture removed from the tank is subjected to ultrasonic treatment either before it is heated or after heating. ! 4. The method according to claim 1 or 2, characterized in that before the ultrasonic treatment, a paraffin dispersant and / or a depressant additive are added to the mixture to lower the crystallization temperature.
