Description
Technical field
The invention belongs to coal chemical technology, particularly relate to the recoverying and utilizing method of a kind of Fischer-Tropsch synthesis oil waste water.
Background technology
The substantial amounts of artificial oil waste water that Fischer-Tropsch synthesis generates, wherein rich in organic compounds such as alcohol, aldehyde, acid, ketone, esters
Thing, its COD is up to more than 10000ppm, and common wastewater biochemical flow process is difficult to effectively process, has a strong impact on equipment safety
Steady production.Artificial oil waste water processes one of difficult point that always coal liquifaction technology solves, and 160,000 tons of ICL for Indirect Coal Liquefaction of Yi Tai
Device is the coal indirect liquefaction device that independent intellectual property right enjoyed by domestic first set, does not has experience to use for reference.
Summary of the invention
In order to solve the problems referred to above that prior art exists, the present invention uses artificial oil waste water configuration water by numerous studies
Slurry additive, solves the problem that artificial oil waste water cannot process, and has accomplished the purpose of water saving, has the most indirectly created the biggest
Economic benefit.
The present invention specifically provides following technical scheme:
The recoverying and utilizing method of a kind of Fischer-Tropsch synthesis oil waste water, it is characterised in that comprise the steps:
1) neutralization of artificial oil waste water
The artificial oil waste water that F-T synthesis technique produces, pH value, at about 3-4, is introduced into and is stored in slurrying tank, adopt
The ammonia-containing water of the higher concentration with fischer-tropsch synthesis process purification section ammonia still process stripper condenser is carried out with artificial oil waste water
Neutralize so that it is pH is increased between 7-7.5；
2) prepared by slurries additive agent
By slurries additive agent mother solution (being mainly composed of sodium lignin sulfonate) that mass concentration is 40%, deposit in interpolation
In agent underground tank, by step 1 in additive tank) the artificial oil waste water that obtains is by after its concentration dilution to 4%, by additive pump
Squeeze in grinding machine, prepare water-coal-slurry, i.e. realize the recycling of artificial oil waste water.
The invention have the advantages that
1, utilize artificial oil waste water water distribution slurry additive, saved a large amount of production water, for reducing coal liquifaction fresh water (FW) consumption
Make the biggest contribution.
2, existing wastewater biochemical flow process is difficult to be effectively treated artificial oil waste water, solves artificial oil waste water and difficulty
The great difficult problem processed.
Observe through longtime running situation and during maintenance, pulping system, gasification furnace and auxiliary device inspection are not all found
Abnormal, it was demonstrated that to be feasible with artificial oil waste water water distribution slurry additive.
Accompanying drawing explanation
Fig. 1 is present invention process schematic flow sheet
Wherein, 1 synthesis water pot, 2-in-1 one-tenth water pump, 3 additive tank, 4 additive pumps, 5 additive mother solution pumps, 6 additive ground
Lower groove
Detailed description of the invention:
First deliver to add from additive underground tank by the additive mother solution (being mainly composed of sodium lignin sulfonate) of gasification 40%
Adding agent tank, then intermediate tank farm synthesis water pot synthetic water is pumped to additive tank by synthetic water and is diluted to by additive mother solution
About 5% (mass fraction), additive delivers to coal pulverizer by additive pump, and 5% additive and coal compare with 1:23 (mass ratio)
Example mixing controlling the water circulation coal slurry.According to current operating mode, consume about 15 tons of additive mother solution every day, need artificial oil by its ratio
Waste water 135 tons, is greatly reduced the processing load of artificial oil waste water.
The artificial oil pH value of waste water that F-T synthesis technique produces is at about 3-4, and acidity is the strongest.For avoiding corroding pulping system
And coal slurry pipeline, it is originally intended to deposit former water as in the slurrying tank of pulping water, uses the condensation of purification section ammonia still process stripper
The ammonia-containing water of the higher concentration that device comes is neutralized with artificial oil waste water so that it is pH controls between 7-7.5.
Utilize artificial oil waste water water distribution slurry additive can save 135 tons of water of production every day, run 340 days meters year, every year
Save production water and reach 45900 tons.While solving the environmental protection bottleneck that coal liquifaction runs, also eliminate process artificial oil waste water high
Cost.And this technology only flow process original to coal liquifaction has carried out the change of appropriateness, but but reach the effect of highly significant.
Term is explained:
F-T synthesis (has another name called F-T synthesis): one of ICL for Indirect Coal Liquefaction technology, (main at catalyst with synthesis gas for raw material
Ferrum system) and appropriate reaction under the conditions of synthesize the technical process of liquid fuel based on paraffin hydrocarbon.
Artificial oil waste water: the by-product that Fischer-Tropsch synthesis generates, wherein rich in organic compounds such as alcohol, aldehyde, acid, ketone, esters
Thing.
Slurries additive agent: made coal slurry will be made to reach high concentration, low viscosity and have good stability, it is necessary to use
Some chemical agents (are mainly composed of sodium lignin sulfonate), referred to as additive.
Light ends oil (abbreviation light oil): typically refer to the hydrocarbon mixture of boiling spread about 50～350 DEG C.
