Abstract
Изобретение относится к области ликвидации нефтяных загрязнений, образовавшихся в результате розлива нефти и нефтепродуктов на грунт, и может быть использовано для рекультивации почв, переработки нефтешламов и выбуренной породы для отделения их от нефти и нефтепродуктов. Технический результат - упрощение способа, повышение производительности, снижение энергозатрат и обеспечение возможности получения товарного продукта - достигается тем, что в способе очистки загрязненного нефтью и/или нефтепродуктами грунта, выбуренной породы, нефтешламов или отработанных буровых растворов, включающем разделение исходного продукта на плавающую и осаждаемую фазы в резервуаре и отмывку разделенных фаз, согласно изобретению осаждаемую фазу перемешивают и транспортируют установленным в резервуаре шнековым конвейером, а затем разделяют на твердую и жидкую фракции под действием центробежных сил в декантере, а плавающую фазу очищают от механических примесей и обессоливают с получением товарной нефти и/или нефтепродуктов. В резервуаре устанавливают контейнер для улавливания крупных механических примесей. Твердую фракцию, поступающую из декантера, обжигают в печи или подвергают биологической очистке. При разделении исходного продукта его нагревают до 90°С. Плавающую фазу очищают от механических примесей в отстойнике, который разделяют перегородкой и барьером для осаждения примесей перед барьером и выпуска очищенного продукта через переливной канал, образованный между перегородкой и барьером. Товарную нефть и/или нефтепродукты после обессоливания подвергают центробежному декантированию для дополнительной очистки отThe invention relates to the field of elimination of oil pollution resulting from the bottling of oil and oil products on the ground, and can be used for soil reclamation, processing of oil sludge and cuttings to separate them from oil and oil products. The technical result is to simplify the method, increase productivity, reduce energy costs and ensure the possibility of obtaining a marketable product is achieved by the fact that the method of cleaning soil polluted with oil and / or petroleum products, drill cuttings, oil sludge or spent drilling mud, including the separation of the original product into floating and deposited the phases in the tank and the washing of the separated phases, according to the invention, the precipitated phase is mixed and transported by a screw conveyor installed in the tank, and then divided into solid and liquid fractions under the action of centrifugal forces in the decanter, and the floating phase is cleaned from mechanical impurities and desalted to obtain commercial oil and / or petroleum products. In the tank set the container for trapping large mechanical impurities. The solid fraction coming from the decanter is calcined in a furnace or subjected to biological treatment. When the separation of the original product is heated to 90 ° C. The floating phase is cleaned of mechanical impurities in the settling tank, which is separated by a partition and a barrier to precipitate impurities in front of the barrier and release the purified product through an overflow channel formed between the partition and the barrier. Crude oil and / or petroleum products after desalting are subjected to centrifugal decanting for additional purification from
