Description
Technical Field
The invention discloses a device for reducing environmental pollution by using heavy marine liquid fuel raw materials, and relates to a combination device of heavy marine liquid fuels.
Background
There are two types of marine fuel oils: fraction-based marine fuel oil and bottom-based marine fuel oil. Distillate-based marine fuel oils, also known as marine low viscosity fuels (MSFs) or marine diesel fuels (MVFs), comprise petroleum fractions separated from crude oil at refineries using distillation processes. Gasoline (also known as medium diesel) is a middle petroleum distillate product having a boiling point range and viscosity between kerosene and engine oil and containing a mixture of C10-19 hydrocarbons. The gas oil is used for house heating and heavy machinery such as cranes, bulldozers, generators, tractors, combine harvesters and the like. In general, maximizing recovery of gas oil from distillation residues is the most economical use of materials by refineries because they can break down gas oil into valuable gasoline and distillate. Diesel is very similar to diesel gas oil and contains mainly a mixture of C10-19 hydrocarbons, including about 64% aliphatic hydrocarbons, 1-2% olefinic hydrocarbons and 35% aromatic hydrocarbons. Marine diesel may contain up to 15% of residual process streams and optionally no more than 5% by volume of polycyclic aromatic hydrocarbons (asphaltenes). Diesel is mainly used as fuel for ground transportation and is mixed with kerosene to form aviation jet fuel.
The bottom fuel or marine Heavy Fuel Oil (HFO) comprises a mixture of process residues of fractions which do not boil or evaporate even under vacuum conditions, with an asphaltene content of 3 to 20 wt.%). Asphaltenes are large, complex polycyclic hydrocarbons that have a tendency to form complex waxy deposits. Once precipitated, asphaltenes are difficult to redissolve, described in the marine and marine fuel depot industry as a sediment at the bottom of liquid fuel tanks.
For over 50 years, large ocean going vessels have been using HTLs to run large two-stroke diesel engines. TSZhT is a mixture of aromatic compounds, distillates and value added tax residues formed during oil refining. Typical streams included in HFTS include: atmospheric bottoms (i.e., atmospheric residuum), vacuum bottoms, visbreaking residuum, light cycle oil FCC (LRG), heavy FCC cycle oil (TRG), also known as FCC bottoms, FCC slurry oils, heavy gas oils and delayed cracking oils (SCR), polyarylarenes, reclaimed engine oils for land transportation and small fractions (less than 20% by volume) of distillate oils, kerosene or diesel oil to achieve a desired viscosity. The HFTS content in the aromatic hydrocarbon is higher than that in the marine distillate fuel. The composition of the HTL is complex and varies depending on the source of the crude oil and the refining process used to extract the greatest value from each barrel of crude oil. The mixture of components is typically characterized by viscosity, high sulfur and high metals, and high asphaltenes, which makes HFTL the only refinery product per barrel cost less than the original crude itself.
Another difficulty in treating heavy oil residues and other heavy hydrocarbons is the inherent instability of each intermediate refinery stream. Those skilled in the art will appreciate that there are many practical reasons for individually treating each refinery stream. One reason for this is the unpredictability of asphaltenes contained in each stream. Asphaltenes are large complex hydrocarbons that have a tendency to precipitate from refinery hydrocarbon streams. Those skilled in the art understand that even minor changes in composition or physical conditions (temperature, pressure) can result in precipitation of asphaltenes that would otherwise dissolve in solution. Once precipitated from solution, asphaltenes can rapidly plug trunks, control valves, coat critical sensing equipment (i.e., temperature and pressure sensors), and often result in significant and costly plant or refinery downtime and production outages. For this reason, refineries have long practiced without mixing intermediate product streams (e.g., vacuum residuum, FCC slurry oils, etc.) and processing each stream in separate reactors.
Disclosure of Invention
The object of the present invention is to reduce environmental pollution of Heavy Fuel Oil (HFO) for ships, to minimize the variation of the required properties of HFO, and to minimize the unnecessary production of by-product hydrocarbons, i.e. light hydrocarbons (C1-C8) and unstabilized naphtha (C5-C20).
The first aspect and exemplary embodiments include a method for reducing environmental pollution in a heavy marine fuel oil feedstock, the method comprising: mixing a quantity of heavy marine fuel oil in a feedstock with a quantity of an activated gas mixture to form a feedstock mixture; contacting the crude mixture with one or more catalysts to form a process mixture from the crude mixture; the process mixture is obtained and the liquid component of the process mixture is separated from the gaseous component and the byproduct hydrocarbon component of the process mixture and the heavy marine liquid fuel is offloaded.
The second aspect and exemplary embodiments include hydrocarbon fuel compositions, referred to herein as heavy marine liquid compositions, consisting essentially of at least a major volume, preferably 85 volume%, more preferably at least 90 volume%. And most preferably at least 95% by volume of the marine fuel oil derived from the disclosed process for reducing environmental contaminants in a marine fuel oil feedstock or optionally produced by an apparatus for carrying out the process.
A third aspect and exemplary embodiments include an apparatus for reducing environmental contaminants in a FATF feedstock and producing a FATF product. The example apparatus includes a first tank, a second tank in fluid communication with the first tank, and a third tank in fluid communication with the second tank, and an unloader line from the third tank for unloading HTS product. The first vessel receives a quantity of HFTS feedstock mixed with a quantity of an activated gas mixture, and the resulting mixture is contacted with one or more catalysts under specific process conditions to form a process mixture. The second vessel receives the process mixture from the first vessel and separates the liquid component from the bulk gas component in the process mixture. The bulk gas component is sent for further processing. The liquid component sent to the third vessel separates any residual gas components and any byproduct hydrocarbon components (mainly light and unstable naphtha) from the treated HALF product, which is subsequently discharged.

Referring to fig. 1, fig. 1 shows a general flow chart for reducing environmental pollution in HFTS feedstock and producing HFTS products according to a first exemplary embodiment. A predetermined volume of HTS feedstock (2) is mixed with a predetermined amount of an activating gas (4) to obtain a feedstock mixture. The feedstock used is generally consistent with the physical and some key chemical properties of marine residual fuels, except for environmental pollution, conforming to ISO8217:2017, more specifically, when the environmental pollutant is sulfur, the concentration of sulfur in the HFTS feedstock may be in the range of 5.0 wt to 1.0 wt%. Regarding the nature of the activating gas, it should be selected from a mixture of nitrogen, hydrogen, carbon dioxide, gaseous water and methane. The gas mixture in the activated gas should have a desired hydrogen partial pressure (pH 2) of greater than 80% of the total pressure of the activated gas mixture (P. Those skilled in the art will understand that the molar content of the activated gas is another criterion, i.e. the hydrogen mole fraction of the activated gas should be in the range of 80% to 100% of the total moles of the activated gas mixture, more preferably when the hydrogen mole fraction of the activated gas is 80% to 99% of the total moles of the activated gas mixture the process mixture (10) is removed from the first vessel (8) and contacted with one or more catalysts and is led by hydraulic communication to a second vessel (12), preferably a gas-liquid separator or a thermal separator and a cold separator, to separate the liquid component (14) of the process mixture from the bulk of the gas component (16) of the process mixture.
The liquid component (16) is directed by hydraulic communication to a third vessel (18), preferably a fuel oil stripping system, to separate any residual gaseous component (20) and byproduct hydrocarbon component (22) from the HFTS product (24). The residual gas component (20) may be a gas mixture selected from nitrogen, hydrogen, carbon dioxide, hydrogen sulfide, gaseous water, light hydrocarbons C1-C5. In the second vessel (12), the residual gas is treated outside the boundaries of the direct process together with other gas components (16) removed from the process mixture (10). The liquid hydrocarbon by-product is a condensable hydrocarbon inevitably formed in process (22) and may be a mixture selected from the group consisting of hydrocarbons C5-C20 (unstable naphtha) (naphtha-diesel) and other condensable light liquid hydrocarbons (C4-C8).
