Abstract

The invention relates to a coal flotation agent, which is characterized by comprising the following components in part by mass: 1 part of oil-containing sludge produced during petroleum exploitation, transportation, storage, processing and oil-containing sewage treatment, 0 to 4 parts of thinner, 0 to 0.5 part of foaming agent and 0 to 0.2 part of regulator. The invention also relates to a preparation method for the coal flotation agent, which is characterized by comprising the following steps of: adding 0 to 4 parts of thinner, 0 to 0.5 part of foaming agent and 0 to 0.2 part of regulator into 1 part of oil-containing sludge in part by mass, and stirring the components uniformly to obtain the coal flotation agent. The coal flotation agent is generated by adopting the oil-containing sludge produced during petroleum exploitation, transportation, storage, processing and oil-containing sewage treatment, so the oil-containing sludge is subjected to pollution-free treatment and resource utilization. The method for producing the coal flotation agent by using the oil-containing sludge has the advantages of high efficiency, secondary pollution resistance, simple and convenient production process, low product cost and the like.

Description

Coal flotation agent and preparation method thereof
Technical field
The invention belongs to chemical field, relate to coal flotation agent and preparation method thereof, particularly relate to a class with oil exploitation, transport, store, oily sludge that the processes such as processing and oily waste water treatment produce is as coal flotation agent of basic material and preparation method thereof.
Background technology
Oily sludge as oil exploitation, transport, store, the processes such as processing and oily waste water treatment follow product, form complicatedly, be comparatively stable suspension emulsion system.Oily sludge bulky not only takies a large amount of arable lands after the discharging, also easily soil, water body and air are caused severe contamination.In recent years, both at home and abroad all at harmless treatment and the application technology as the second resource of active development oily sludge.At present the processing method of oily sludge mainly comprises bioanalysis, extraction, hot washing method etc., generally has complex process, problem that cost is higher, and the oil that processes, water, solid three-phase impurity content are larger, difficultly searches out suitable purposes.
Floatation is the most effectual way of slime separation.China is as the country of coal production in the world and consumption figure maximum, annually consumes nearly 1,000,000 tons of coal flotation agent, and consumption is also increasing year by year.Coal flotation agent generally is comprised of the less hydrocarbons of polarity, surfactant and dispersant etc.
Oil exploitation, transport, store, contain more rich hydrocarbons in the oily sludge that the processes such as processing and oily waste water treatment produce, also contain the compositions such as surfactant, dispersant.Its hydrocarbons can be used as the collecting agent of coal flotation agent, and surfactant, dispersant etc. can be used as active ingredient or the synergist of coal flotation agent.Also not having in the market a kind of main component is the coal flotation agent of oily sludge.
Summary of the invention
The purpose of this invention is to provide one by oil exploitation, transport, store, coal flotation agent that oily sludge that the processes such as processing and oily waste water treatment produce is made as basic material and preparation method thereof.Take oily sludge as basic material, according to the specific performance requirement of Coal rank to coal flotation agent, add the auxiliary agents such as diluent, foaming agent and adjusting agent, prepare coal flotation agent.
For solving the problems of the technologies described above, the technical solution used in the present invention is: coal flotation agent, the oily sludge that it is characterized in that with oil exploitation, transport, store, processing and oily waste water treatment process produces comprises the component of following proportion by weight as basic material:

Diluent 0~4;
Foaming agent 0~0.5;
Adjusting agent 0~0.2.
Described diluent is one or more in light diesel fuel, kerosene, aromatic hydrocarbons, shale diesel oil, atmosphere 3rd side cut oil, natural gas cold oil or the industrial tar; Described aromatic hydrocarbons is C 8~C 12Component.Diluent reduces flotation agent viscosity except playing, improves the effect of flotation agent dispersibility, itself also is the active ingredient of flotation agent.
Described foaming agent is one or more in secondary octanol, n-octyl alcohol, cyclohexanol, terpenic oil, industrial fusel, fatty oil, butyl ether oil or the methyl anyl alcohol.
Described adjusting agent is one or more in APES, DR oil emulsion, flocculant or the pH adjusting agent.
The preparation method of coal flotation agent is characterized in that: according to the mass fraction, with 0~4 part of diluent, 0~0.5 part of foaming agent and 0~0.2 part of adjusting agent, add in 1 part of oily sludge, stir, can obtain coal flotation agent.Described mixing time is 20-80 minute.
The present invention take oil exploitation, transport, store, oily sludge that the processes such as processing and oily waste water treatment produce is as basic material, according to the specific performance requirement of Coal rank to coal flotation agent, on the basis of the existing component of oily sludge, rationally add the auxiliary agents such as diluent, foaming agent and adjusting agent, produce high-efficiency coal flotation agent.
The present invention compared with prior art has the following advantages:
Adopt oily sludge to produce coal flotation agent and not only make oily sludge obtain harmless treatment, also make it obtain recycling.Produce coal flotation agent with oily sludge as basic material, have the efficient height, do not produce secondary pollution, and the outstanding advantages such as production technology is easy, low cost product, will produce the environment and economy benefit of highly significant.
