Description
Technical Field
The invention relates to the technical field of clean energy, in particular to a low-sulfur marine residual fuel oil emulsifier.
Background
The green water clear mountain is the Jinshan Yinshan, and at present, the environmental protection requirement is more and more strict. Marine fuel oils are all evolving towards low sulfur. The residual fuel oil produced in oil refineries can not meet the requirements of environmental protection regulations. It is very difficult to reduce the 50% sulphur content in the GB17411-2015 marine fuel oil standard. The reason is that 1, the production cost of the low-sulfur fuel oil is greatly increased; 2. low sulfur residual fuel oil resources are limited; 3. the residual fuel oil contains a large amount of heterocyclic aromatic hydrocarbon, polycyclic aromatic hydrocarbon and polycyclic aromatic hydrocarbon. Carcinogens 3.4 benzopyrene and haze-generating PM2.5 are contained in the exhaust gas pollutants after combustion.
Disclosure of Invention
The invention aims to solve the problems of high sulfur and high pollution of marine residual fuel oil, and provides a low-sulfur marine residual fuel oil emulsifier.
In order to achieve the purpose, the invention adopts the following technical scheme:
the low-sulfur marine residual fuel oil emulsifier comprises the following raw materials in parts by weight: span-80250-550 parts, fatty alcohol-polyoxyethylene ether 50-250 parts, palmitic acid 55-65 parts, ethanol 200-550 parts, isooctyl nitrate 2-4 parts, and 3448N detergent dispersant 2-4 parts.
Preferably, the 3448N detergent dispersant is a mixture of polyisobutylene amine and polyether.
Preferably, the cleaning agent comprises span-80500 parts, fatty alcohol-polyoxyethylene ether 200 parts, palmitic acid 60 parts, ethanol 234 parts, isooctyl nitrate 3 parts and 3448N cleaning dispersant 3 parts.
Preferably, the detergent comprises, by weight, span-80400 parts, fatty alcohol-polyoxyethylene ether 150 parts, palmitic acid 60 parts, ethanol 384 parts, isooctyl nitrate 3 parts, and 3448N detergent dispersant 3 parts.
Preferably, the cleaning agent comprises span-80300 parts, fatty alcohol-polyoxyethylene ether 100 parts, palmitic acid 60 parts, ethanol 534 parts, isooctyl nitrate 3 parts and 3448N cleaning dispersant 3 parts.
Preferably, the low-sulfur bunker fuel oil emulsifier further comprises 1-3 parts of epoxidized fatty acid methyl ester.
The flash point is the minimum temperature at which a liquid can ignite by vaporization using an ignition source under specified test conditions. The flash combustion is the phenomenon that when enough steam is generated on the surface of the liquid and is mixed with air to form combustible gas, the liquid is subjected to a fire source to generate transient fire light, and the liquid is instantly combusted. The lowest temperature of flash-off is called the flash point. The flash point is a safety index for storage, transportation and use of flammable liquids, and is also an index of volatility of flammable liquids. Flammable liquid with low flash point, high volatility, easy ignition and poor safety.
The epoxy fatty acid methyl ester is light yellow liquid at normal temperature, is a novel environment-friendly plasticizer taking the fatty acid methyl ester as a main raw material, and is a nontoxic and tasteless polyvinyl chloride plasticizer and stabilizer. The inventor finds that the addition of a small amount of epoxidized fatty acid methyl ester to the system can effectively increase the flash point, and the effect has significant dose dependence, and is slightly too large, so that the effect is not significant and even has the tendency of reducing the flash point.
The invention also provides a preparation method of the low-sulfur marine residual fuel oil emulsifier, which comprises the following steps:

s2: adding the residual fuel oil meeting GB17411-2015 for the ship into a No. 2 oil mixing tank, adding the solution A into the No. 2 oil mixing tank, laterally extending into an oil tank mixing stirrer, and uniformly stirring the residual oil and the emulsifier to obtain a solution B;
s3: heating the solution B in the No. 2 oil mixing tank to 70 ℃, then adding soft water into the No. 2 oil mixing tank, laterally extending into an oil mixing mixer of the oil mixing tank, uniformly stirring, stirring while feeding the semi-finished emulsified fuel oil in the No. 2 tank into an ultrasonic emulsification device by a gear pump through a static mixer, and obtaining a solution C;
s4: and (3) filtering the solution C from the emulsifying device by a filter screen, then feeding the solution C into a No. 3 finished product tank, storing the solution C for 24 hours, performing oil product analysis, and if all indexes meet the indexes of the residual fuel oil for the ship in GB17411-2015, finding out the reason if the product is qualified, and retreating the product by using the ultrasonic emulsifying device again.
Preferably, the size parameter of the filter screen is 400 meshes.
