Embodiment 1

[0054]Oil-based mud treatment, oil-based mud is the oil-based mud mixed with a large amount of drill cuttings produced during the oil and gas field production process, accompanied by the use of oil-based drilling fluid during the drilling process. Molecular polymer mixed with rock debris, containing water (<10%), oil (15-40%), and solids (50-70%).

[0055] according to figure 1 As shown, the treatment adopts physicochemical conditioning module, dehydration module, thermal desorption module, flue gas treatment module, sewage treatment module and auxiliary module. The module adopts a drying machine and a centrifuge, first drying and then centrifuging; the thermal desorption module adopts a two-stage inner auger type furnace body; the flue gas treatment module includes a secondary combustion device, a three-phase separation device and a bag dust removal device ; Auxiliary modules are nitrogen generation / storage device and mobile master control room.

[0056] In the thermal deso...

Embodiment 2

[0058] Water-based mud treatment, water-based mud is the waste containing various chemical agents mixed with a large amount of drill cuttings produced during the drilling process of oil and gas fields. A mixture of high molecular polymers such as lubricants, anti-slump agents, flow regulators, and oil-preserving materials and drilling cuttings, containing water (<5%), oil (10-20%), and solids (50-70%) %).

[0059] according to figure 2 As shown, the treatment adopts the physical and chemical conditioning module, dehydration module, drying / drying module, flue gas treatment module, and sewage treatment module. The drying / drying module adopts a drum-type high-efficiency drying device; the flue gas treatment module includes a secondary combustion device, a three-phase separation device and a bag dust removal device.

[0060] The maximum reaction temperature in the drum-type high-efficiency drying device: 150-300°C, the residence time of the material at the maximum reaction temp...

Embodiment 3

[0062] Landed sludge treatment, landed sludge is the oily sludge produced by well site operations and pipeline equipment leakage in the process of oilfield exploitation, including crude oil transportation, equipment maintenance and oil well breaking process, crude oil leakage to the ground, blowout and blowout accidents, etc. The crude oil caused by the leakage of crude oil on the ground and other reasons flows to the ground, thereby forming a landing sludge on the ground. Landed sludge contains a mixture of crude oil, sand and gravel, and weeds. The light components are volatilized, and the heavy oil is mainly black, viscous, coarse, and contains a lot of weeds, woven bags, large pieces of gravel, etc. Foreign matter, containing water (5-10%), oil (5-10%), and solid (80-90%).

[0063] according to image 3 As shown, the treatment adopts the sorting and impurity removal module, the physical and chemical conditioning module, the dehydration module, the thermal desorption modul...

Abstract

The invention relates to the field of oily sludge treatment and specifically relates to a method for constructing a sludge treatment system based on a sludge component. The method is suitable for the treatment of the sludge with the oil content from 5% to 50% and the water content from 0% to 85%. The method comprises the following steps: 1) dividing modules: dividing 9 modules according to a treatment process required by the sludge treatment under the above conditions, namely, a sorting impurity removing module, a materialization tempering module, a dewatering module, a drying/desiccation module, a pyrolysis desorption module, a pyrolysis carbonizing module, a flue gas treatment module, a wastewater treatment module and an auxiliary module; 2) sludge variety determining: determining the sludge variety according to the oil content or resource of the sludge; 3) selecting the modules: selecting the modules required by the treatment process according to the sludge variety; and 4) constructing a system: constructing and assembling a device according to the selected modules.

Description

technical field [0001] The invention relates to the field of oily sludge treatment, in particular to a method for building a sludge treatment system based on sludge components. Background technique [0002] According to the different sources of oily sludge, its water content, oil content and solid content are very different, so the treatment of oily sludge is a huge systematic project. The construction method of traditional sludge treatment projects mixes various treatment equipment together, and does not systematically design various treatment processes in modules, resulting in the need for separate design and construction of each treatment project in various sludge treatment projects Handling equipment requires a lot of effort. Contents of the invention [0003] The purpose of the present invention is to solve the problems in the background technology and provide a method for building a sludge treatment system based on sludge components, which simplifies the process of ...
