Abstract

The invention relates to the technical field of high-temperature thermal analysis and particularly relates to an oil-containing sludge treatment method. The resource treatment method of the oil-containing sludge comprises the following steps that an incineration system heats up quartz sand; the heated quartz sand enters a thermal analysis system after cyclone separation; heat is transmitted to the oil-containing sludge by the high-temperature quartz sand, so that the oil-containing sludge reacts in a thermal analysis manner under a high-temperature anaerobic environment; the generated thermal analysis gas passes through a three-phase separator, so that oils, water and non-condensable gases are separated; coke bottom and the quartz sand in the thermal analysis residue are returned to the incineration system for being recycled. The resourceful treatment method disclosed by the invention has characteristics of high crude oil recovery, no secondary pollution and low energy consumption, so that various oil-containing sludge treatment and disposal problems generated in oil-field development and an oil refining process are effectively solved. The whole technical system is energy-saving and environment-friendly; meanwhile, resourceful, reduction and harmless treatment of the oil-containing sludge is realized.

Description

1. Technical field:

[0001] The invention relates to the technical field of high-temperature thermal analysis, in particular to a method for resourceful treatment of oily sludge. 2. Background technology:

[0002] During the development and production of oil fields, a large amount of oily sludge is inevitably produced. According to preliminary investigations, the annual increase of oily sludge in my country is about 800,000 tons. Because the oily sludge contains water, sediment, sulfide, benzene series, phenols, hydrocarbons, etc., it not only occupies land and space, but also seriously Pollution of air, soil and groundwater restricts the development of domestic oil field production to a certain extent. Oily sludge has been listed as hazardous solid waste (HW08) by the state. Therefore, it is of great practical significance for the sustainable development of oilfields to develop a treatment technology that can eliminate the environmental hazards of oily sludge and recycle res...
