Abstract
The invention relates to petroleum coke pulp, a preparation method and application thereof. The product of the invention contains petroleum coke, heavy oil and additive. The specific formula and preparation method can be referred to detailed specification. The product of the invention has the advantages of heat value, viscosity, cleanness and burning properties similar to the heavy oil. However, compared with the heavy oil, the manufacturing cost is much lower. The product can replace the heavy oil and can be directly used for fuel industrial (civilian) kiln; no transformation corresponding to the kiln and associated equipment is needed.
Description
Technical field
The invention belongs to petrochemical industry, be specifically related to a kind of preparation, storage, transportation and using method of refinery coke liquid fuel.
Technical background
Refinery coke is the solid phase prod of petrochemical industry delayed coking unit.Its calorific value height, ash content is little, price is relatively cheap, is good clean solid fuel.The solid-fuelled main application approach in present stage oil Jiaozhuo is: mix in the coal, or be directly used in the burning of industrial fluidized bed boiler, cement kiln, its fuel grade is summed up as the coal class, can not embody the high added value of refinery coke as the high heating value clean fuel.CN99107793.8 " a kind of grizzle water slurry body composition and use thereof with the refinery coke modification ", CN99107794.6 " a kind of refinery coke water slurry body composition and use thereof with the grizzle modification " etc. attempt refinery coke is made the burnt slurry of water, but the hydrophobicity of refinery coke is too strong, be difficult to pulping, need to add coal pulping altogether, when adding coal, also carry into ash content, generate the burnt slurry of oil coking coal water, this slurry can not embody the cleaning and the high heating value performance of refinery coke, can not be in aspect and coal water slurry differentiation such as product performance, environmental protection and purposes.
Guangdong enlightening Santex Group cooperates with the Liaohe Oil Field, successfully refinery coke is made the burnt slurry of water, and is applied to the injection boiler of Liaohe Oil Field.But because the point of ignition height of refinery coke, combustionvelocity is slow, can not in existing oil-firing boiler, directly burn, or combustion is clean, want water burnt slurry replacement for heavy (crude oil) and be used for oil-firing boiler, need carry out large-scale redevelopment to oil-firing boiler, need the client to increase a large amount of boiler improvement investments, this has limited applying of the burnt slurry of water.In addition, the burnt slurry of water carries a large amount of water, can not be used to fire the not water-proof product of sintering procedure, has also limited its application.
Summary of the invention
The objective of the invention is to release a kind of high heating value refinery coke liquid product of cleaning, replacement for heavy (crude oil) when significantly reducing client's fuel cost, need not the fuel oil kiln to the client, supporting storing and transporting system even use habit and transforms.
The present invention realizes goal of the invention by following measure:
1, production formula (mass ratio):
Heavy oil 30-90%
Refinery coke 10-70%
Additive 0.0-20%
2, production method
Refinery coke by hammer (Hubei Province formula etc.) crusher, is crushed to the refinery coke grain of granularity less than 50mm; Jiao grain is sent into ball mill (rod mill etc.) grinds, with refinery coke be ground to granularity greater than 200 orders, tail over petroleum coke powder less than 3%, be preferably ground to granularity greater than 250 orders, tail over petroleum coke powder less than 3%.
In heavy oil suction reactor, heating, stir, under 70-80 ℃, the additive of disposable adding formula ratio.Continue to heat up, stir, under 90-100 ℃, begin to add coke powder, about 1 hour of coke powder joining day, charge temperature is 90-100 ℃, and feed pressure is a normal pressure.After coke powder adds, continued insulation reaction about 15 minutes, check, discharging gets the petroleum charred slurry finished product.
3, product fundamental property
The product fundamental property sees Table 1.
4, Commercial application
No. 2 kilns successively try for 3 times to burn product of the present invention in Yingkou, Liaoning Province factory of Golden Bridge of blue and white group 2 workshops respectively in July, 2006, August, September, and its processing condition are:

With a spiral pump, be with 4 spray guns,
Processing requirement: atomize, 1300-1750 ℃ of kiln hall temperature is adjustable.
Fire product: the magnesium chromium firebrick.
Examination sintering fruit is as follows:
1, petroleum charred slurry can be the same with heavy oil (catalytic slurry), with the technical process of former klining heavy oil, uses the 2mm nozzles, realizes stable burning.
2,1300-1750 ℃ of kiln hall temperature is adjustable.
3, energy consumption nominal data and heavy oil are basic identical.
4, do not find coking point or carbon black on kiln discharge refractory brick, kiln car, combustion processes is not found tempering phenomenon yet, the petroleum charred slurry burning is described fully.
The storage of petroleum charred slurry fuel and conveying
The character of petroleum charred slurry and 380CST oil fuel or 200# heavy oil are basic identical, need insulation to store and conveying.Handling equipment can be selected spiral pump, toothed gear pump, lobe pump etc. for use.
The loading and unloading of petroleum charred slurry fuel and transportation
The same with heavy oil, petroleum charred slurry need be incubated loading and unloading and transportation.
The application of petroleum charred slurry fuel
The alternative heavy oil of petroleum charred slurry is directly used in RF kiln, need not the original equipment flow process is transformed.
