Abstract
The invention relates to a preparation method for gasification slurry for producing synthetic gas. The gasification slurry is prepared by grinding the following raw materials in part by weight in a mill: 45 to 75 parts of coal, 1 to 50 parts of oil sludge or slurry oil, 20 to 45 parts of water, 0.09 to 2.7 parts of a dispersing agent and 0.01 to 0.30 part of an auxiliary. Compared with conventional gasification slurry prepared from coal, the gasification slurry prepared by the method has the advantages that the solid content is as high as about 2 to 4 percent, the stability is enhanced, and the viscosity is moderate, so that the gasification slurry is high in transportation performance; when the conventional device is used for preparing the gasification slurry from a mixture of the oil sludge or the slurry oil and coal, the addition of other equipment is avoided. According to the method, oil sludge or slurry oil waste is harmlessly treated, active ingredients C and H in the oil sludge or slurry oil waste is resourcefully utilized, and remarkable environment-friendly benefits are created.
Description
[technical field]
The invention belongs to technical field of coal chemical industry.More specifically, the present invention relates to a kind of preparation method of the gasification slip for the production of synthetic gas.
[background technology]
The greasy filth that the present invention uses is the throw out that the oil-water-dirt produced in oil recovery process mixes bottom danger wastes or refinery crude oil storage tank, primarily of mixing compositions such as oil in water emulsion, water, suspended solids.Because its particle is tiny, in flocs unit shape, water content is high, bulky, not easily realizes the three phase separation of oil-water-mud, and containing heavy metal ion and inorganic salts compound; Refinery mud is also containing toxic substances such as a large amount of benzene homologues, phenols, pyrene, anthracenes.Greasy filth directly discharge can take a large amount of soil, and objectionable impurities meeting polluted water, soil and air that it contains, worsen ecotope, also cause petroleum resources to waste simultaneously, and having to pass through technology management step could directly discharge.
At present, more valued contained Mud Treatment Technology mainly contains modified-mechanical dehydration, biological treatment, solidification treatment and recycling etc. both at home and abroad.
US 4383927 and US 4938877 individually discloses the technology of modified-mechanical dehydration technique refiltered oil, by adding tensio-active agent, thinner, ionogen or emulsion splitter (negatively charged ion or nonionic), wetting agent, pH value regulator etc., and be aided with the modified means such as heating visbreaking (optimum temps more than 50 DEG C), effectively can realize oil-water-mud three phase separation, but the mud cake produced also needs further process.
The people such as Xu Zengde are being entitled as " technical study of oily sludge microbiological treatment " (" biotechnology ", 15th volume the 2nd phase 61-64 page in 2005) in describe through microorganism be separated, screening and inducing culture seed selection to suitable bacterial strain, utilize this bacterial strain to oily sludge through anaerobic treatment, carry out aerobic de-oiling again, from mud, deviate from crude oil reclaimed.But, exist and such as select suitable bacterial classification difficult, long processing period, to naphthenic hydrocarbon, aromatic hydrocarbons, heterocyclic poor processing effect, to technical problems such as the difficult adaptations of high oily sludge;
The people such as Dang Juanhua are being entitled as " research of oily sludge innoxious process for treating " (" oil-gas field environment protection "; 14th volume the 3rd phase 31-32 page in 2004) in report add solidifying agent in oily sludge; wherein portion of water and toxic substance solidification is made by physical-chemical reaction; thus greatly can reduce the rate of release of objectionable impurities; but solidification sludge is stacked and is occupied big area soil, and adds organic curing agent and also may bring secondary pollution.
Zhang Zhi crowd waits people to list solvent extration refiltered oil technology, prepare the application technology as the second resource such as carbon containing absorbent being entitled as in " treatment technology of oily sludge and recycling " (" Journal of Tangshan College ", the 22nd volume the 3rd phase 77-80 page in 2009).But the cost performance of extraction agent is not high, limit its application; Prepare carbon containing absorbent complex process, cost is higher, and oil removal rate is lower.
In order to overcome the technological deficiency of process for treating oil-containing sludge, the present inventor develops preparation method and the technique of a kind of greasy filth or slurry oil and coal mixing gasifying slip, by greasy filth or slurry oil are used for gasifying in slip, make full use of active principle C and H wherein, realize recycling; Greasy filth or slurry oil can be avoided simultaneously directly to discharge the detrimentally affect produced environment, reduce environmental protection treatment expense, realize harmless treatment.
