Description
Technical Field
The invention relates to the field of oil sludge treatment, in particular to an intensive oil sludge treatment pry.
Background
Sludge is a major contaminant generated during petroleum development, production, and processing. According to different causes, the oil sludge is mainly divided into floor oil sludge, tank bottom oil sludge, ground spilled oil, oil-containing sludge of oil refinery and the like.
The components and complexity of the oil sludge are different according to different geological conditions and production processes, and generally consist of water, soil, oil organic matters and the like. The sludge has the following characteristics: high water content and large volume; the components are complex, and the treatment difficulty is high; contains a large amount of dirty oil and combustible substances; most of the harmful components exceed the emission standard. At present, although the pollution control technology of the domestic and foreign oily sludge is numerous, no targeted pollution control technology exists.
The method for treating the oily sludge at home and abroad generally comprises the following steps: incineration, biological treatment, heat washing, solvent extraction, solid-liquid separation, coking, profile control of oily sludge, comprehensive utilization of oily sludge, etc. However, many of the methods have some problems, and are not suitable for practical application, such as large energy consumption and easy secondary pollution of the incineration method, and the oil resources are not recycled; the biological treatment method can biodegrade 97% of petroleum hydrocarbon only after 41 days, and the oil resources are not recycled; the solvent extraction method has the problems of long flow, complex process and high treatment cost, and is only applicable to oily sludge containing a large amount of refractory organic matters; the solid-liquid separation method has low oil recovery rate for the oil-containing sludge with high oil content and serious pollution. These methods have not been effectively popularized and applied in China.
In the prior art, the following problems mainly exist in the treatment process of the sludge:
1. the chemical agent is required to be added in the process of treating the sewage sludge, so that the treatment cost is high; if the medicament is improperly managed in the process of use, storage and transportation, secondary pollution is easily caused, and even personal safety and environmental safety are endangered;
2. the partial treatment method needs to burn the residual residue, and the residual petroleum in the residue is burnt out, which is a great waste of resources; and the waste gas generated after combustion has high nitrogen, sulfur and other contents, and is easy to carry out secondary pollution on air;
3. part of treatment methods adopt a reinjection mode to reinject the sewage sludge into a water injection well, and the service life of the water injection well is possibly influenced; meanwhile, the petroleum contained in the oil sludge can not be utilized, so that resources are wasted;
4. the existing treatment method has low efficiency and small treatment capacity, and the quantity of the accumulated dirty oil sludge in each large oil field in China is too large to be treated in time, so that the environment is polluted continuously; the partial treatment method needs to heat the oil sludge to a higher temperature, and has high energy consumption and high cost.
