Abstract
The invention provides a method for cleaning aged oil sludge. The method comprises the steps of firstly collecting aged oil sludge from an oil field, compounding a biological surfactant (rhamnolipid), a chemical surfactant (TX-100) and an aid (NaSiO39H2O) in a certain mass ratio under conditions of certain temperature, stirring speed, stirring time, liquid-solid ratio and mass concentration, cleaning the aged oil sludge, standing, and separating after an oil phase, a liquid phase and a solid phase are layered. Due to large proportion of petroleum heavy components in the aged oil sludge, the aged oil sludge is difficult to clean. According to the method, the biological surfactant, the chemical surfactant and the aid are compounded to clean the aged oil sludge, so that a relatively good elution effect is achieved, and the biological surfactant, the chemical surfactant and the aid have a synergistic effect during the compounding and cleaning.
Description
Technical field
The present invention relates to a kind of purging method for cleaning aging greasy filth, be specifically related to a kind of compound drug that screens to clean the technological method of aging greasy filth, it belongs to environment remediation technical field.
Background technology
In petroleum industry, the meeting being difficult to avoid in the treating processes such as production, storage, transport, processing of oil produces a large amount of greasy filth, the overall complicated component of greasy filth, arbitrary discharge and stacking, and all can threaten to the environment of surrounding and the mankind.Environmental Protection Agency (US EPA) is classified as priority pollutant, during petroleum sludge is listed in by China " National Hazard refuse catalogue ".If greasy filth processes not in time, stack for a long time, through air-dry aging, light component reduces, and cause pollutent to have higher molecular weight, viscosity and density, its resin and asphalt petroleum fraction proportion is large, and the adhesion of crude oil and soil is stronger, this further increases difficulty for oil-sludge treatment.Greasy filth is the pollutent that can not effectively utilize in petroleum industry, but also comprise valuable oil, therefore to greasy filth carry out innoxious while realize resource utilization, be of practical significance, surfactant washing method is the method for low, the efficient fast processing greasy filth of a kind of processing cost, obtain extensive research, chemical surfactant SDS, AEO-9, TritonX-100 etc. have been proved to be has good cleaning performance.At present, along with people are to the attention of bio-surfactant, start adopt bio-surfactant to clean oil-polluted soils and find to there is good effect, especially rhamnolipid.The cleaning of greasy filth is not only relevant with clean-out system, and soil type and character also affect cleaning performance.Therefore, bio-surfactant process Different Soil is adopted to have practical significance.Some research chemical surfactant anionic and nonionic types are composite, and result shows that cleaning performance has synergy.Rhamnolipid as a kind of aniorfic surfactant, can with nonionic surface active agent and additive compound, study its cleaning performance to aging greasy filth, provide foundation for bio-surfactant is applied to the cleaning of aging greasy filth.
Summary of the invention
1. the object of this invention is to provide a kind of method of cleaning aging greasy filth, it is characterized in that, its step is as follows:
(1) gather greasy filth, shady and cool ventilation place is air-dry, crosses 2mm and screens out assorted, is loaded on sealing bag and preserves stand-by;
(2) ratio being 20: 1 according to liquid-solid ratio in the washers adds greasy filth and scavenging solution, and rinse liquid temperature is 70 DEG C, rhamnolipid: TX-100:NaSiO
39H
2the mass ratio of O is 0.1: 1: 4, and total mass concentration is 5.1%; Stirring velocity cleans 30min under the condition of 400r/min, then leaves standstill, and is separated after layering.
(3) scrape off oil slick, incline supernatant liquor, dries, measure its resid amount by 37 DEG C, greasy filth after cleaning.
2. the method for the aging greasy filth of cleaning according to claim 1, is characterized in that, the clean-out system of employing is bio-surfactant and chemical surfactant and additive compound, and what bio-surfactant adopted is rhamnolipid; That chemical surfactant adopts is TX-100; Auxiliary agent: NaSiO
39H
2o.
3. purging method according to claim 1, is characterized in that: it is applied to air-dry aging greasy filth, it is characterized in that, the volatilization of light component major part, the content of heavy component (as bituminous matter, colloid) raises, and is combined with soil more tight, cleaning is difficult.
4. aging greasy filth harm is large, difficult, and employing surfactant washing method not only can remove the oil in soil, can also carry out oily resource reclaim.Rhamnolipid is as a kind of novel green surfactant and nonionogenic tenside TX-100 and auxiliary agent NaSiO
39H
2the aging greasy filth of the composite cleaning of O, not only has good eluting rate, and the existence of rhamnolipid also helps the biological restoration of the rear greasy filth of cleaning.
Embodiment:
The present invention is illustrated further in conjunction with following concrete case study on implementation.Need to illustrate, following embodiment only for explaining the present invention, and does not limit the scope of application of the present invention.
Embodiment:
(1) Dagang Oilfield taken from by the aging greasy filth in the present embodiment, and greasy filth shady and cool ventilation place is air-dry, cross 2mm screen out decon, be put in sealing bag preserve stand-by.Table 1 gives total petroleum hydrocarbons content in greasy filth, and Four composition: the content of stable hydrocarbon, aromatic hydrocarbons, bituminous matter, nonhydrocarbon.Can obtain from table, total petroleum hydrocarbons content (TPH) is 389g/kg, and its studies on asphaltene accounts for 15.7%, nonhydrocarbon 19.6%, and heavy constituent content is higher, and greasy filth degree of aging is larger.
Table 1 huge port greasy filth oil-contg and each component proportion situation
(2) cleaning of greasy filth: adopt 150ml beaker as washer, adding 100ml deionized water, is 5.1% according to total mass concentration, mass ratio be 0.1: 1: 4 ratio add rhamnolipid 0.1g, TX-1001g, NaSiO
39H
2o 4g, heating in water bath is to after 70 DEG C, and be add huge port greasy filth 5g at 20: 1 according to liquid-solid ratio, low whipping speed is clean 30min under the condition of 400r/min, then stops leaving standstill, and is separated after the solid layering of fluid.
(3) scrape off oil slick, incline supernatant liquor, dries at 37 DEG C, greasy filth after cleaning, adopts ultrasonic extraction method to measure its resid amount.Resid amount is 105g/kg, and eluting rate reaches 72.90%.
