Abstract
The invention relates to a cleaning agent for organic sediments inside an oil tank and a preparation method of the cleaning agent. The cleaning agent comprises the following components in percentage by mass: 30%-60% of tetramethoxy-propane, 20%-40% of dimethoxy-ethane, 5%-15% of diethylene glycol octyl ether, 2%-10% of sodium polyphosphate, 1%-1.5% of sodium alkyl benzene sulfonate and 2%-3.5% of lauryl sodium sulfate. The cleaning agent disclosed by the invention can be cleaned on line and also be cleaned off line, generates no influence on production because of no need of shutdown when used for cleaning on line, so that cost and time are saved; the cleaning agent is harmless to an operator because an operator unnecessarily enters the oil tank, is pollution-free on the environment, can be used for recovering 90% hydrocarbon by recycling sludge and has the advantages of outstanding economic benefit, simple preparation method, short cleaning operation time, high cleaning quality, ecological and environmental friendliness, no three wastes discharge, no need of anti-rust treatment on a container after cleaning, good social benefit and economic benefit, harmlessness on human bodies, no corrosion on equipment and no secondary pollution.
Description
Technical field
The present invention relates to a kind of clean-out system, be specifically related to a kind of efficient, pollution-free, operating procedure is easy and waste oil a kind of high-efficiency environment friendly clean-out system that can reuse after cleaning.
Background technology
Crude oil contains low molecular hydrocarbon and heavy organic substances (paraffin, bituminous matter, colloid etc.), Oil extraction, transfers in process and has been mingled with moisture, silt and a small amount of mechanical impurity.In storage tank, leave standstill for some time, due to density difference, at the bottom of tank, form greasy filth gradually.Bottom greasy filth in crude oil storage tank is made up of inorganic sediments and organic sediments usually, and inorganic sediments comprises iron rust, sand, mud and moist carbon etc.; Organic sediments comprises crude oil, wax, pitch etc.The settling of analyse crude oil storage tank, finds that crude oil and wax account for 80% ~ 95% of whole sludge, other in addition to water, inorganic sediments is little.
The harm that oil tank mud brings: (1) reduces petroleum tank storage power; (2) reduce downstream unit heat exchanger efficiency, increase fuel and general facilities consumption; (3) affect electric desalting to run, increase tower top corrosion; (4) sewer oil-contg increases; (5) clean sludge can increase petroleum tank inspection and maintenance expense.
Therefore petroleum storage tank needs regularly carry out maintenance and inspection and remove sludge in tank, and in the greasy filth of crude oil storage tank, major part is useful material, is a kind of resource, should be recycled, make full use of hydrocarbon resources, effectively realizes resource and maximizes.Current domestic traditional tank cleaning method mainly utilizes manually, and it is large that artificial clear tank also exists labour intensity, the problems such as long construction period, poor stability, crude oil recovery rate are low, contaminate environment.Along with a large amount of construction of Chinese large-sized petroleum storage tank and the pay attention to day by day to environmental protection problem; artificial clear tank has not met the objective requirement of Environment and development; eliminate the certainty that artificial clear tank is history; therefore; be necessary to provide a kind of material; former oil recovery can be realized, reach cleaning performance again simultaneously.
Summary of the invention
In order to overcome the shortcoming of currently available technology, the object of invention is to provide a kind of clean-out system effectively removing oil tank organic sediments, it is good that the present invention has cleaning performance, can effectively shorten the tank cleaning time, drop into manpower few, safety is secure, operating procedure is easy, being easy to control can online or off-line cleaning, and the crude oil recoverable after cleaning, environmentally safe, to personal fanout free region.
For achieving the above object, the present invention is by the following technical solutions: organic sediments clean-out system and preparation method thereof in a kind of oil tank, this clean-out system is made up of than component following quality: 30 ~ 60% tetramethoxy propanes, 20 ~ 40% glycol dimethyl ethers, 5 ~ 15% Diethylene Glycol octyl ethers, 2 ~ 10% sodium polyphosphates, 1 ~ 1.5% sodium alkyl benzene sulfonate, 2 ~ 3.5% sodium lauryl sulphate.
Organic sediments clean-out system preparation method in a kind of oil tank, adopts following steps to obtain:
A takes starting material according to mass ratio 30 ~ 60% tetramethoxy propane, 20 ~ 40% glycol dimethyl ethers, 5 ~ 15% Diethylene Glycol octyl ethers, 2 ~ 10% sodium polyphosphates, 1 ~ 1.5% sodium alkyl benzene sulfonate, 2 ~ 3.5% sodium lauryl sulphate;
The tetramethoxy propane taken, glycol dimethyl ether and Diethylene Glycol octyl ether mix by B;
Taken sodium polyphosphate, sodium alkyl benzene sulfonate and sodium lauryl sulphate add in the obtained mixture of step B by C successively, fully stir, and mix rear obtained clean-out system of the present invention.
Prove through test and practical effect, compared with prior art, the present invention has following beneficial effect:
1, the cleaning process of clean-out system of the present invention is the stripping effect of physics, does not occur to dissolve and emulsification, greasy dirt and scavenging solution natural separation after cleaning, and greasy dirt is recycled;
2, clean-out system of the present invention can on-line cleaning also can clean by off-line, and on-line cleaning does not need to stop work, do not have an impact to production; Cost-saving, save time; Personnel are not needed to enter in tank, to operator without harm; Environmentally safe; Recycling sludge, can reclaim the hydro carbons of 90%, remarkable in economical benefits;
3, product of the present invention can directly be applied, and also can dilute with crude oil or carrier solvent, and on-line continuous adds and can be used for clean deposition thing or prevent deposition generation;
4, the raffinate after clean-out system process of the present invention can direct sewage effluent Treatment stations, can not impact sewage farm;
5, product preparation method of the present invention is simple, and the cleaning operation time is short, and cleaning quality is high, ecological, environmental protective, three-waste free discharge, do not need antirust treatment to container after cleaning, has good Social and economic benef@;
6, the clean-out system in the present invention can carry out gas phase cleaning simultaneously and liquid phase clear: this clean-out system is under 80 ~ 125 DEG C of conditions, both tower tray and headspace in knockout tower was cleaned by steam driven with gas phase state, can be dissolved in again with liquid phase state cleaning equipment bottom line and equipment in water, easy to use, saving scavenging period, saving steaming tower steam consumption;
7, the clean-out system in the present invention can preferably by Iron sulfuret cleaning with break oil-water emulsion cleaning and combine, and by affecting safety, the material such as Iron sulfuret, hydrogen sulfide of environmental protection better cleans up;
8, the raffinate after the present invention's cleaning adds emulsion splitter, recyclable valuable sump oil, the qualified discharge of sewage;
