Abstract
The emulsifying and sulfur-reducing agent consists of sorbitan fatty ester 6-7 wt%, alkylphenol ethoxylate 18-21 wt%, triethanolamine 12-14 wt%, aldehyde-containing compound 1.8-2.2 wt%, sodium nitrate 11-13 wt%, calcium-containing oxide 10-12 wt% and water 38-41 wt%. The positive effect of the present invention is that the emulsifying and sulfur-reducing agent is added into high-sulfur heavy fuel oil to emulsify to form emulsified fuel oil, which may be stored at normal temperature for 1-2 years without water-oil separation and stored at 90 deg.c for 30 days without demulsification and water separation; and has complete combustion with no black smoke and less SO2 and other harmful gas produced. The present invention is favorable to environment protection and best utilization of fuel oil resource.
Description
Technical field
The present invention relates to a kind of emulsifying agent, particularly a kind of emulsification sulfur reducing agent.
Background technology
Along with the development of petroleum industry, the improving constantly of oil Refining Technologies, residual oil or low-volatility fuel oil viscosity increase, and its sulphur content increases to some extent, and this brings difficulty to use, causes the sulfurous gas in the tail gas of burning back higher, serious environment pollution.In order to reduce content of harmful gas in the air, reduce environmental pollution, the application of exploitation high-sulfur reduced fuel oil, desulfurization test research becomes popular topic.In prior art, " emulsifying fuel oil with environmental protection and energy saving advantages " that national patent CN112057AA announces adds emulsifying agent, the aqueous solution, energy-saving agent etc. in gasoline, diesel oil or kerosene, make the environmental protection and energy saving oil in water emulsion, thereby reduction pollutant discharge amount, reduce cost, but be only limited to vapour, diesel oil, it is not obvious to fall the sulphur effect." improvement high-sulfur oil in water emulsion is the technology of low-sulfur oil in water emulsion " that national patent CN1053002C announces, be to adopt low sulfur heavy crude oil or heavy oil (residual oil) dilution high-sulfur emulsified orinoco crude oil, burning back sulfur dioxide in flue gas content reduces to some extent than direct burning oli oil, but need to use a large amount of sweet crude oil or heavy oil, and the sulfurous gas reduction is relevant with the sweet crude oil consumption." a kind of high sulfur heavy fuel desulfurating agent and the application thereof " that national patent CN1319647A announces adds sweetening agent in the high-sulfur emulsified orinoco crude oil, and its sweetening effectiveness can be up to standard, but with dosage big (7%-10%), cost height.
Summary of the invention
At last art problem, the invention provides a kind of emulsification sulfur reducing agent, it is added in high sulfur heavy fuel oil, add 15%-20% water simultaneously, carry out emulsification, make emulsified fuel oil, reach and make full use of high-sulfur reduced fuel oil resource, reduce the environmental pollution purpose.
To achieve these goals, the present invention adopts following technology: a kind of emulsification sulfur reducing agent, it is characterized in that: it by sorbitan fatty acid ester, alkylphenol polyoxyethylene, trolamine, aldehyde-containing compounds, SODIUMNITRATE, contain calcium oxide and water and mixed and form, its percentage composition is by weight: sorbitan fatty acid ester 6-7%, alkylphenol polyoxyethylene 18-21%, trolamine 12-14%, aldehyde-containing compounds 1.8-2.2%, SODIUMNITRATE 11-13%, contain calcium oxide 10-12%, water 38-41%.
Further, described aldehyde-containing compounds comprises formaldehyde, acetaldehyde, propionic aldehyde, butyraldehyde, hexanal, and each prescription is only selected wherein 1-2 kind component for use.
Further, the described calcium oxide that contains comprises calcium oxide and calcium hydroxide, selects 1-2 kind component for use in each prescription.
Further, described sorbitan fatty acid ester comprises sorbitan monooleate and sorbitan monostearate, selects 1-2 kind component for use in each prescription.
Further, described alkylphenol polyoxyethylene is polyoxyethylene octylphenol ether and polyoxyethylene nonylphenol ether, selects 1-2 kind component for use in each prescription.
Positively effect of the present invention is: it is added in the high-sulfur reduced fuel oil, carry out emulsification, make emulsified fuel oil, deposit under the normal temperature and can not produce the water oil separation phenomenon in 1 to 2 year, can deposit under 90 ℃ 30 days, can not separate out moisture by breakdown of emulsion; Firepower is prosperous during burning, and burning does not fully produce black smoke, and discharge of harmful gases such as sulfurous gas is up to state standards fully in the tail gas, helps protecting environment, makes full use of the high-sulfur fuel resource.
Embodiment
The preparation of a kind of emulsification sulfur reducing agent of the present invention: earlier calcium oxide is mixed with water, fully stirring makes its dissolving, adds after SODIUMNITRATE stirs again, and all the other whole components addings are stirred, and makes the emulsification sulfur reducing agent, and product is all effective.During use by heavy oil: agent: the proportioning of water=84.5: 0.5: 15 is made emulsification heavy oil by emulsifying device.
