Description
Technical field
The utility model relates to petrochemical industry, especially relates to a kind of device that utilizes catalytically cracked oil to produce marine fuel oil.
Background technology
Marine fuel oil be a kind of thermal value large, have good burning performance, shelf-stable, corrosion is little, use range is wide good fuel oil, be the most economical and desirable fuel of marine engine, also can be used as the boiler oil of middle-size and small-size nozzle.
According to ISO international standard and GB/T 17411 national standards, marine fuel oil specifically is divided into distillate fuel oil peculiar to vessel and residual fuel oil peculiar to vessel (standard-required of ZB/T 17411-1998 sees attached list 1 and 2).Distillate fuel oil component peculiar to vessel is heavy gas oil, belongs to the oil fuel of " costliness ", and usage quantity is less; For the purpose that reduces the ship expense, add the development of oil Refining Technologies and, to the raising of poor quality oil preconditioning technique, it is residual fuel oil peculiar to vessel that the ship engine majority uses oil fuel inferior.
Conventional ship by the production method of residual fuel oil is, uses residual oil, comprises that vacuum residuum, visbreaking residue etc., as main raw material, call in part diesel oil, to improve the flowing property of residual oil, reaches the oil fuel that conformance with standard requires.Residual fuel oil peculiar to vessel is for high-power, low speed boat diesel engine.
During oil fuel is produced, once in a while also can be with catalytic slurry as being in harmonious proportion one of raw material, catalytic slurry refers to the material that the Fractionator Bottom of catalytic cracking unit is extracted out.Due to slurry oil, containing catalyst dust, while making the mediation raw material of oil fuel, the ash content of oil fuel is increased greatly, easily produce the furnace wall fouling or cause motor fault, therefore call in the oil fuel of slurry oil and often do not accepted by the user.
Usually the purposes of slurry oil is: return to catalytic cracking and again carry out cracking, be in harmonious proportion and make boiler oil or other fuel, make coking raw material, make asphalt stock etc.Because the slurry oil main component is the condensed-nuclei aromatics of short-side chain, the main contributions that returns to catalytic cracking is coke and the gas of low value, even obtain liquid product, be the aromatic hydrocarbons that character is severe, stability is bad, so slurry oil is not the good raw material of catalytic cracking unit yet.Slurry oil, containing catalyst dust, is made the mediation raw material of boiler oil or other fuel, easily produce the furnace wall fouling or cause motor fault, thereby the restriction slurry oil is called in the oil fuel usage quantity.Equally, the catalyst dust problem has limited the consumption that slurry oil is made coking raw material.So, for refinery, slurry oil is troubling reluctant oil product.
The catalytic slurry of processing through denitrating catalyst is called clarified oil, and wherein most of catalyzer is removed.The catalytic slurry that relatively there is no denitrating catalyst, clarified oil is more suitable in making the oil fuel component, and the mediation amount in oil fuel can must improve greatly.But the slurry oil clarified oil still, containing a small amount of catalyzer, still can produce the furnace wall fouling or cause motor fault.
A kind of catalytically cracked oil that utilizes patent of invention that catalytically cracked oil is produced marine fuel oil technique to propose to come from the bottom of catalytic cracking fractionating tower enters the vacuum fractionation tower, carries out underpressure distillation, isolate tower top light oil slurry and tower at the bottom of tops starch two portions.The light oil slurry is sent into the dehydration hold-up vessel with pump, through standing gravity settling, water is taken off to after lower than 0.5%, light oil slurry is as the residual fuel oil peculiar to vessel that the meets national standard ZB/T 17411-1998 sale of dispatching from the factory, perhaps with will dewater light oil slurry of pump, extract out, in pipeline, with blend component, mixed, enter the mediation hold-up vessel after venturi mixer, when blend component is diesel oil, can produce the distillate fuel oil peculiar to vessel that meets national standard ZB/T 17411-1998, when blend component is residual oil, can produce the residual fuel oil peculiar to vessel that meets national standard ZB/T 17411-1998.The device of a set of production marine fuel oil of needs matches with above-mentioned production marine fuel oil technique.
