Abstract
The present invention relates to dewatering agent and the application of coalite tar in a kind of being applicable to.To be that the methyl alcohol of above-mentioned two kinds of polyether quality part sums is composite by the alkyl phenolic resin Soxylat A 25-7 of 0.5 ~ 1 mass parts, the phenol amine aldehyde resin Block polyoxyethylene polyethenoxy ether of 1.5 ~ 4 mass parts and mass parts form this Coal tar dehydrant, and the molecular weight of above-mentioned two kinds of polyethers is all 5000 ~ 8000.When using Coal tar dehydrant of the present invention, need to add 0.5-1kg dewatering agent in middle coalite tar per ton, make coal tar water ratio be reduced within 4%, meet the water content requirement of readymade coal tar.This dewatering agent have rate of water loss fast, temperature required low, using dosage is little and the advantage that cost is low, can reduce enterprise cost.
Description
Technical field
The present invention relates to a kind of dewatering agent for middle coalite tar and utilisation technology thereof, be specifically related to middle coalite tar dewatering agent and application, it is mainly used in the dehydration of middle coalite tar.
Background technology
Coal tar is a kind of mixture of complexity, and its main component is apolar substance, immiscible with water.Moisture in coal tar is fine liquid particles shape and is closely wrapped up by coal tar, and due to the existence of the superfine coal dust of particle, coke powder, pyrolytic carbon, contained humidity and coal tar form stable suspension.Therefore, the difficulty of coal tar dehydration is very large.And during coal tar processing, about 400 DEG C need be heated to, but the just vaporization 100 DEG C time of coal tar contained humidity, very high pressure can be produced at 400 DEG C.This may cause pipeline and flange explosion, even causes fire.In addition, distillation tower internal pressure is relatively high, destroys original distillation balance, reduces the separation efficiency of coal tar, affect quality product.So coal tar dehydration technique becomes the key factor affecting coal tar following process.
Coal tar breaking dehydrating method has multiple, is mainly summarized as physical method, biological method and chemical process.Emulsion splitter breaking emulsion and dewatering belongs to chemical process.Compared to crude oil demulsification dehydration, few to the breaking emulsion and dewatering of coal tar report, also insufficient to probing into of the influence factor of breaking emulsion and dewatering and mechanism.And dewatering agent needed for the coal tar of Different sources is also different.When ensureing product quality, develop or optimize coalite tar ammoniacal liquor separating agent in one, both improve the energy consumption of product quality and output, reduction ammonia still and interchanger, reduced the blocking of ammonia spray nozzle, the working ability of tar deep processing device can have been improved again, reduced plant energy consumption, reduce potential safety hazard.Therefore important realistic meaning is had to blue charcoal and tar production enterprise.
Summary of the invention
The technical problem that dehydration temperaturre is high, dewatering agent consumption is large, dewatering time is long and energy consumption is high existed in coalite tar dehydration during the present invention will solve, provides coalite tar in a kind of being applicable to is quick, less energy-consumption is dewatered middle coalite tar dewatering agent and application.
Solving the problems of the technologies described above adopted technical scheme is: middle coalite tar dewatering agent, it is characterized in that: to be that the methyl alcohol of above-mentioned two kinds of polyether quality part sums is composite by the alkyl phenolic resin Soxylat A 25-7 of 0.5 ~ 1 mass parts, the phenol amine aldehyde resin Block polyoxyethylene polyethenoxy ether of 1.5 ~ 4 mass parts and mass parts form for it, and the molecular weight of above-mentioned two kinds of polyethers is all 5000 ~ 8000.
Described middle coalite tar dewatering agent, is characterized in that: it forms by the methyl alcohol of the alkyl phenolic resin Soxylat A 25-7 of 0.5 mass parts and the phenol amine aldehyde resin Block polyoxyethylene polyethenoxy ether of 3 mass parts and 3.5 mass parts is composite.
The application of described middle coalite tar dewatering agent in middle coalite tar dehydration; Described middle coalite tar is temperature at the coal tar of 600 ~ 800 DEG C, density 1.0705 g.cm
-3.
Middle coalite tar is heated to 60 ~ 80 DEG C, adds Coal tar dehydrant while stirring, the Coal tar dehydrant amount added in coal tar per ton is 0.5 ~ 1kg, and constant temperature leaves standstill 4 ~ 12 hours.
Advantage of the present invention is: Coal tar dehydrant of the present invention is applicable to coalite tar dehydration in North Shaanxi, dewatering agent consumption is few, and temperature required low, dewatering agent is cheap, coal tar moisture can be made to be down to less than 4% by 11.4%, to meet the requirement of readymade coal tar.Compared with existing dewatering, there is the advantage that dewatering speed is fast, cost is low, energy consumption is low.
