Abstract
The present invention relates to a kind of greasy filth and clean coal facies bonded application technology as the second resource, disclose a kind of production method of clay coal water slurry.Feed composition and weight percent are: oil field mud 15-35%, 200 mesh sieves account for the pulverized bituminous coal 42-58% more than 80%, water 18-28%, viscosity reduction dispersion agent 0.5-1.5% excessively.The present invention is simple to operate, less energy consumption, and cost is low, does not produce secondary pollution.The clay coal water slurry good fluidity of producing, stability is strong, burnout rate is high, satisfy the requirement of boiler fully to fuel combustion or gas making, not only alleviated present problem with the coal anxiety, and effectively utilized greasy filth, reach greasy filth and handle minimizing, resource utilization, innoxious requirement, have good market outlook and promotional value.
Description
Technical field:
The present invention relates to a kind of greasy filth and clean coal facies bonded application technology as the second resource, specifically oil field mud and coal dust are mixed stirring preparation clay coal water slurry under the effect of a small amount of additive, can be widely used in coal water slurry boiler, kiln and coal slurry gasifier.
Background technology:
Greasy filth is one of important pollutent that produces in oil-field development and the storage and transport process, also is a great problem that restriction oil field environmental quality continues raising.The composition of greasy filth is extremely complicated, mainly is made up of water, silt and oils three parts, and the three presents highly stable suspension emulsified state, and contains a large amount of waxs, bituminous matter, colloid, bacterium, salt, heavy metal, corrosion product and various water conditioners etc.The oily sludge that mainly is divided into the Oil extraction generation by its source (is mainly derived from Ground Processing System, the oily sludge that produces in the oil extraction-generated waste water treating processes), the oily sludge (being mainly derived from the tank bottom oil sludge of block station, joint station) of oil field gathering and transportation process generation, sewage from oil refinery are handled oily sludge (be mainly derived from oil trap bed mud, flotation cell scum silica frost, petroleum tank bed mud etc., be commonly called as " three mud ") three major types that produces.Bulky because of it, not only take a large amount of arable lands after the greasy filth discharging, and surrounding soil, water body, air are all polluted.Along with most of oil fields enter the middle and later periods mining phase, extraction Water in oil rate is more and more higher, and greasy filth output also will continue to increase.
Traditional coal-water-slurry is a kind of by about 70% coal dust, water about 30% and a little auxiliary are mixed with the liquid that forms, can be as oil pumping, atomizing, accumulating, and can be directly used in the burning of various boilers, kiln, changed the traditional combustion mode of coal.Oil field mud, coal dust and a small amount of additive are mixed with clay coal water slurry, burning-point is low, the volatile matter advantages of higher because oil field mud has, the clay coal water slurry of preparation has good burning and gasification property, under the condition of not adding stablizer, can stablize for a long time simultaneously and deposit, reduce production cost.
Summary of the invention:
The objective of the invention is to make full use of the petroleum substance in the greasy filth, provide a kind of simple to operate, less energy consumption, the clay coal water slurry production method that cost is low.
Raw material of the present invention is formed weight percent:
Oil field mud 15%-35%
Cross 200 mesh sieves and account for pulverized bituminous coal 42%-58% more than 80%
Water 18%-28%
Viscosity reduction 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 viscosity reduction dispersion agent is benzyl naphthalene sulfonic formaldehyde condensation compound, sulfonation sodium humate, polyoxyethylene glycol and yellow soda ash, and the feed composition weight percent is respectively benzyl naphthalene sulfonic formaldehyde condensation compound 20%-50%, sulfonation sodium humate 20%-50%, polyoxyethylene glycol 10%-30% and yellow soda ash 0-10%.
Described oil field mud is selected from oily sludge, the oily sludge of oil field gathering and transportation process generation or the oily sludge that sewage from oil refinery is handled the field generation that Oil extraction produces.
Advantage of the present invention and positively effect are: simple to operate, and less energy consumption, cost is low, does not produce secondary pollution; The clay coal water slurry sludge forming performance of producing is good, and the greasy filth addition can be more than 20%, and apparent viscosity is below 1000mPas simultaneously; The thermal value of oil field mud and contains a large amount of volatile hydro carbons generally between 2000-3500kcal/kg, adds a certain amount of greasy filth and can not have a significant effect to thermal value, has improved the burning burnout rate and the gasification efficiency of slip; Make full use of the stability of greasy filth self, need not to add stablizer, long-time placement can not produce layering or hard-caked sediment phenomenon, and good fluidity; Make slurry have good shear shinning characteristic by adding efficient viscosity reduction dispersion agent, change the clay coal water slurry combustionproperty of the ratio readjust production of adding greasy filth, satisfy the requirement of boiler, have good market outlook and promotional value fuel combustion or gas making.
