Abstract
The invention discloses a method for producing solid fuel from oil refining acid sludge. A neutralizer is added into the acid sludge to completely neutralize acids in the acid sludge into sulfates and organic slats and then the solid fuel is obtained, wherein a dispersing agent capable of dispersing the solid fuel is mixed in the neutralizer and is oil shale or coal; and the mass ratio of the neutralizer to the dispersing agent is 1:(0.3-0.6). The method of the invention is simple and feasible and has the advantages of no sewage, environment friendliness, low treatment cost and the like. The obtained solid fuel can be piled, conveyed and used as the oil shale or the coal. The method has relatively good social benefit and certain economic benefit.
Description
Technical field
The present invention relates to a kind of recoverying and utilizing method of refining oil acid sludge, is that a kind of utilization oil refining acid sludge is produced solid-fuelled method specifically, and it can make innoxious, the resource utilization of oil refining acid sludge.
Background technology
Since have less investment, simple to operate flexibly, advantages such as constant product quality, product good light stability, sulfuric acid refining process particularly still has more extensively in the WHITE OIL PRODUCTION process at refining of petroleum products and adopts.The disadvantage of sulfuric acid refining process is to produce a large amount of acid sludges.Because acid sludge contains objectionable impuritiess such as sulfuric acid, organic acid, oils, sulfonated bodies, sulfide and nitride, so must handle it timely and effectively.Otherwise can serious environment pollution.
The main method of handling at present acid sludge has: be used as fuel in manufacture of cement, make common calcium phosphate, system sodium sulfate, low temperature pyrogenation method reclaims SO
2, steam and to separate the system dregs of fat, system pitch, produce white carbon black and slushing oil, production sulphur ammonium, produce gypsum etc.These methods exist all that investment is big, deficiency in economic performance, secondary pollution problems is arranged.
Publication number is that the Chinese patent application of CN1528863 discloses a kind of method for refining acid residue for petroleum treatment.This method comprises that acid sludge is added alkali at a certain temperature carries out neutralization reaction, and thermal dehydration and heating are decomposed sulfonic acid under negative pressure state.Acid sludge becomes product pitch or oil fuel after treatment.
Publication number be CN1740295 Chinese patent application a kind of method of utilizing acid sludge to produce heavy oil is disclosed, first adding used oil and mixing in the acid sludge, add calcium hydroxide powder then, be stirred to boiling then, the usage ratio of acid sludge and used oil is 1: 0.8～1: 1.2 weight ratio, and the consumption of calcium hydroxide powder is 60%～80% weight ratio of acid sludge.
Above-mentioned disclosed two patent applications all are to adopt the neutral way, all have the working substance of reuse acid sludge effectively, and can not cause dysgenic advantage to environment.
Summary of the invention
The purpose of this invention is to provide that a kind of cost is lower, the utilization of non-secondary pollution oil refining acid sludge produces solid-fuelled method, this solid fuel is loose shape, no stink, neutrality, calorific value is higher than the resinous shale calorific value, can be used as brick field fuel, or is used to make honeycomb briquette, coal water slurry etc.
Utilization oil refining acid sludge provided by the invention is produced solid-fuelled method, this method is neutralizing agent to be joined to mix in the acid sludge make the acid in the acid sludge be neutralized into vitriol and organic salt fully, obtain solid fuel, described neutralizing agent is mixed with the evacuating agent that the solid fuel that can make gained is loose shape, and the mass ratio of neutralizing agent and evacuating agent is 1: (0.3～0.6); Described evacuating agent is resinous shale powder or coal dust; Described neutralizing agent is a limestone powder; The granularity of limestone powder, resinous shale powder and coal dust is below the 2mm.
After acid in the acid sludge was neutralized into vitriol and organic salt fully, by the quality of acid sludge, acid sludge per ton also added 10～20 kilograms of sulphur-fixing agents.
Described sulphur-fixing agent is the following limestone powder of granularity 2mm.
The present invention utilizes limestone powder as neutralizing agent, and raw material sources are easy, cost is low, and suitably excessive limestone powder can be made the sulphur-fixing agent of combustion processes.
The present invention in and the time adopt resinous shale powder or coal dust as evacuating agent, the adding may command temperature of reaction of resinous shale powder or coal dust makes reaction temperature and carries out, reduces the reaction pair equipment used and corrodes.Simultaneously, resinous shale powder or coal dust are because of wherein inorganic salt and sulfuric acid reaction make the solid fuel of gained become fluffy inflammable.
Method simple possible of the present invention has and does not have sewage, advantage such as environmental protection, non-secondary pollution, processing costs are low.
The solid fuel of gained of the present invention can equally be disposed stacking, transportation, use with resinous shale or coal.Calorific value is higher than the resinous shale calorific value, can be used as brick field fuel, or is used to make honeycomb briquette, coal water slurry etc.Have good social benefit and certain economic benefits.
Embodiment
In following examples, the neutralizing agent limestone powder is got below the granularity 2mm after powder essence is sieved by Wingdale; Evacuating agent resinous shale powder or coal dust are respectively that resinous shale or coal are got below the granularity 2mm after powder essence is sieved; The sulphur-fixing agent limestone powder is got below the granularity 2mm after powder essence is sieved by Wingdale.
Embodiment one:
Is that 1: 0.3 mixed is even with limestone powder and resinous shale powder by mass ratio, join in the acid sludge mix the acid that makes in the acid sludge and be neutralized into vitriol and organic salt fully after, again by the quality of acid sludge, acid sludge raw material per ton adds 15 kilograms of limestone powders, must be the solid fuel of loose shape after mixing.The solid-fuelled calorific value of gained sees Table 1.
Embodiment two:
Is that 1: 0.6 mixed is even with limestone powder and resinous shale powder by mass ratio, join in the acid sludge mix the acid that makes in the acid sludge and be neutralized into vitriol and organic salt fully after, again by the quality of acid sludge, acid sludge raw material per ton adds 20 kilograms of limestone powders, must be the solid fuel of loose shape after mixing.The solid-fuelled calorific value of gained sees Table 1.
Embodiment three:
Is that 1: 0.45 mixed is even with limestone powder and coal dust by mass ratio, join in the acid sludge mix the acid that makes in the acid sludge and be neutralized into vitriol and organic salt fully after, again by the quality of acid sludge, acid sludge raw material per ton adds 10 kilograms of limestone powders, gets the solid fuel of loose shape after mixing.The solid-fuelled calorific value of gained sees Table 1.
