Embodiment 1

[0029] like figure 1 As shown, the treatment methods of oily sludge on offshore platforms include pretreatment, thermal desorption and desorption treatment, tail gas treatment, and wastewater treatment;

[0030] The pretreatment steps include sorting and crushing of foreign matter. The sorted oily sludge is transported to the thermal desorption reaction kettle, and the foreign matter is crushed and then transported to the thermal desorption reaction kettle.

[0031] The thermal desorption and desorption treatment is completed in the thermal desorption and desorption reactor, and the inner wall of the thermal desorption and desorption reactor is heated simultaneously with the interior of the thermal desorption and desorption reactor. The interior of the thermal desorption reaction kettle is heated by superheated steam, and the superheated steam is introduced from the lower part of the thermal desorption reaction kettle, and then sprayed from the central axis of the thermal deso...

Abstract

The invention belongs to the technical field of processing of oily sludge and particularly relates to a processing method of oily sludge on an offshore platform. The processing method of the oily sludge on the offshore platform comprises pyrolysis desorption processing, tail gas processing and waste water processing; the pyrolysis desorption processing is completed in a pyrolysis desorption reaction kettle, the inner wall of the pyrolysis desorption reaction kettle and the inside of the pyrolysis desorption reaction kettle are simultaneously heated, the pyrolysis desorption reaction kettle is vertically arranged, and the oily sludge is discharged from the pyrolysis desorption reaction kettle after being subjected to transverse centrifugation and vertical rollover in the pyrolysis desorption reaction kettle; the tail gas processing is used for processing tail gas obtained after a pyrolysis product generated in the pyrolysis desorption reaction kettle is subjected to three-phase separation; the waste water processing is used for processing waste water obtained after the pyrolysis product generated in the pyrolysis desorption reaction kettle is subjected to three-phase separation. According to the processing method of the oily sludge on the offshore platform, when an occupied area of equipment is reduced, processing efficiency of the oily sludge can be improved.

Description

technical field [0001] The invention belongs to the technical field of oily sludge treatment, in particular to a treatment method for oily sludge on an offshore platform. Background technique [0002] With the development of offshore oil, more and more attention has been paid to the pollution of marine environment caused by oil sludge produced in the development of offshore platforms. In 2008, my country formulated GB49142008 "Limits of Pollutant Emission Concentration in Offshore Oil Exploration and Development", which regulates the treatment and equipment of pollutants generated in offshore oil exploration and development. Commonly used treatment methods are mainly divided into three categories according to different principles: physical and chemical methods, biochemical methods and electrolytic methods. At present, the mature technology in China is to adopt LRET technology, that is, to mechanically separate oil-based drilling cuttings-heat-recover and recycle the desorpt...
