Abstract
The invention relates to a method for preparing a novel environment-friendly water coke slurry fuel by using the resource recycling technology of combining oily water and water coke slurry. The novel environment-friendly water coke slurry fuel comprises the following raw material components in percentage by weight: 62 to 72 percent of petroleum coke powder of which over 80 percent of the petroleum coke powder passes a 200-mesh sieve, 28 to 38 percent of oily water and 0.5 to 1.5 percent of dispersant, wherein the components are mixed and stirred at normal temperature under normal pressure to form high-dispersion stable slurry. The method has the advantages of simple operation, low energy consumption and low cost; the prepared water coke slurry has good fluidity and strong stability, does not need to add a stabilizing agent, fully meets the requirement of a boiler for fuel combustion, realizes the resource recycle of the oily water, reduces the treatment cost of the oily water, and has good market prospect and popularization value.
Description
Technical field:
The present invention relates to the application technology as the second resource that a kind of oily water combines with the burnt slurry of water, specifically oily water and petroleum coke powder are mixed stirring preparation slip fuel under the effect of paucidisperse agent.
Background technology:
With the exploratory development production of landing field and marine oil and Sweet natural gas, the oily(waste)water amount also increases year by year.Oil-contaminated water of oil field mainly contains the sewage that produces after oil extraction-generated waste water, drilling well and well flushing waste water and the crude oil demulsificationization.These sewage are the oil concentration height not only, and contains a large amount of suspended solids and other pollutents.At present, recover the oil and to enter secondary, tertiary phase in the oil field, makes to contain a large amount of chemical additives and microemulsified oil particles in the oil-contaminated water of oil field.The emulsion splitter that adds when chemical agent that injects when this part chemical additive mainly is oil recovery and crude oil demulsification mainly comprises polyacrylamide, polyethylene glycols, OP series, Span series, Tween series etc.These chemical additives and micro emulsion carburetion all have stable structure, and therefore difficult degraded has increased the difficulty of handling.These sewage disposals are bad, not only contaminate environment, and waste resource; Handle proper, then energy-conservation environmental protection again.
The burnt slurry of traditional water is to be main raw material with petroleum coal Jiao, mixes a kind of liquid fuel that forms with water and additive, and its burning that atomizes form is similar to coal water slurry, has ash content low (0.2%～1.4%), mobile, good stability, calorific value height, advantages such as environmental protection.Utilize oily water to prepare the burnt slurry of water; owing to contain complicated high molecular polymer, tensio-active agent and a small amount of microemulsified oil droplet in the oily water; can make the petroleum coke powder stable suspersion in water; only needing to add a spot of dispersion agent makes petroleum coke powder wetting; need not to add stablizer and just can prepare stable slip fuel; steady state can reach the boiler combustion requirement, has realized the recycling of oily water, plays the effect of protection environment.
Summary of the invention:
The objective of the invention is to realize the recycling of oily water, reduce the processing cost of oily water, provide a kind of simple to operate, less energy consumption, the burnt slurry of the water production method that cost is low.
Raw material of the present invention is formed weight percent:
Cross 200 mesh sieves and account for petroleum coke powder 62%-72% more than 80%
Oily water 28%-38%
Dispersion agent 0.5%-1.5%
Described raw material is mixed stirring at normal temperatures and pressures form the stable slurry of high dispersing.
Described dispersion agent is sodium polystyrene sulfonate, naphthalenesulfonic acid-formaldehyde condensate, polyoxyethylene glycol and yellow soda ash, and the feed composition weight percent is respectively sodium polystyrene sulfonate 20%-50%, naphthalenesulfonic acid-formaldehyde condensate 20%-50%, polyoxyethylene glycol 10%-30% and yellow soda ash 0-20%.
Described oily water comprises the sewage that produces after oilfield produced water, drilling well and well flushing waste water and the crude oil demulsificationization.
Advantage of the present invention and positively effect are: working method is simple, less energy consumption, and cost is low, does not produce secondary pollution; Realize the recycling of oily water, reduced the processing cost of oily water, saved a large amount of clean water resources; Contain complicated high molecular polymer and tensio-active agent in the oily water, utilize the sterically hindered benefit of macromolecular chain and the special lypohydrophilic character of tensio-active agent make refinery coke can the long period stable suspersion in water, under the situation of not adding stablizer, just can reach viscosity low (apparent viscosity is below 1500mPas), stable high requirement, long-time placement can not produce layering or hard-caked sediment phenomenon, and good fluidity has reduced production cost; Contain a certain amount of oil content in the oily water simultaneously, improved the slip calorific value of preparation, satisfy boiler, have good market outlook and promotional value the fuel combustion requirement.
