PROCESS FOR THE PREPARATION OF AN INTERMEDIATE PITCH FOR MANUFACTURING CARBON PRODUCTS

Until now, it has not yet been succeeded to prepare high performance carbon fibers having satisfactory strength from heavy oils of coal or petroleum origin. We now succeeded to prepare an excellent intermediate pitch which allows the preparation of high performance carbon fibers having tensile strength of higher than 300 Kg/mm2 and Young's modulus of 50 ton/mm2. The intermediate pitch can be obtained by heating a heavy oil of coal or petroleum origin in a tubular heater under a specific conditions, and then flash distilling the heater effluent in a flash distillation column under a specific condition so as to remove lighter fractions and recovering heavy fraction from the column bottom as the intermediate pitch. The process for the preparation of the intermediate pitch is simple and economical and allows continuous production without fluctuation of quality of the intermediate pitch. The intermediate pitch is also suitable for the production of higher density carbon products.

INTERMEDIATE PITCH FROM HEAVY OILS

PITCH DEMETALIZATION BY DESTRUCTION DISTILLATION

Pitch (the faction boiling above 524.degree.C) of low metals content is produced by delayed coking of a heavy hydrocarbon oil with a high metals content. In a first delayed coking step, the gaseous and liquid phase is removed and sent to a fractionation unit. The bottoms from the fractionation unit are (a) subjected to a second delayed coking to produce coke which meets electrode grade specifications for metals, or (b) catalytically hydrocracked for conversion of distillate products. The demetalized pitch produced in the first delayed coking operation is also a valuable product for use as a binder in the production of coke for electro-metallurigical applications.

PITCH DEMETALIZATION BY DESTRUCTION DISTILLATION

REFINERY PROCESS FOR HEAVY OIL AND BITUMEN

A bitumen and heavy oil upgrading process and system is disclosed for the synthesis of hydrocarbons, an example of which is synthetic crude oil (SCO). The process advantageously avoids the waste attributed to residuum and/or petcoke formation which has a dramatic effect on the yield of hydrocarbon material generated. The process integrates Fischer-Tropsch technology with gasification and hydrogen rich gas stream generation. The hydrogen rich gas generation is conveniently effected using singly or in combination a hydrogen source, a hydrogen rich vapour from hydroprocessing and the Fischer-Tropsch process, a steam methane reformer (SMR) and autothermal reformer (ATR) or a combination of SMR/ATR. The feedstock for upgrading is distilled and the bottoms fraction is gasified and converted in a Fischer-Tropsch reactor. A resultant hydrogen lean syngas is then exposed to the hydrogen rich gas stream to optimize the formation of, for example, the synthetic crude oil. The hydrogen lean gas stream may also be effected by a water gas shift reaction, singly or in combination or in addition with the hydrogen rich gas stream generation. A system for effecting the processes is also characterized in the specification. Refinery processes are additionally set forth incorporating the modifications in numerous variations to produce high value refinery products such as gasoline, diesel and jet fuel.

MULTI-LAYER STEAM GRID FOR HEAT AND MASS TRANSFER IN A TAILINGS SOLVENT RECOVERY UNIT

A grid of pipes for conducting steam at a pressure greater than a vessels' operating pressure and delivering the steam throughout the grid forms the internals for a tailings solvent recovery unit. The delivery of steam throughout the grid aids in maintaining a relatively low partial pressure throughout the vessel to act as a driver for mass transfer. Conducting the steam at the higher pressure through the pipes in the grid permits a surface of the pipes to be heated to a temperature higher than possible in a conventional vessel, increasing the heat transfer to the feed stream which flows through the grid.

By reducing the water content of oil sludge, which arises, for example, on board ships in the purification of fuels and lubricants, its calorific value is increased to such an extent that it can be burned without additional further fuels. The oil sludge is treated in a vessel under a vacuum of 0.04 to 0.4 bar and at a temperature which is 15 to 30 DEG C above the boiling point of pure water at the same vacuum. During the treatment, the oil sludge is taken off from the bottom of the vessel, circulated and reinjected into the upper part of the vessel above the liquid level. As soon as a sufficiently low water content of less than 30% is found in the circulated oil sludge, the largely dehydrated sludge is taken off and further untreated sludge is filled into the vessel.

Processing of oil sludge for combustion and equipment provided for this purpose

Oil sludge which arises at a high water content, for example on ships, is processed by reducing the water content, so that it can be burned, for example, without added fuel. The oil sludge is introduced into a heated vessel which is under a low pressure. Sludge is taken off continuously from the bottom of the vessel and re-introduced by means of a sludge circulation pump and lines into the top of the vessel, where the sludge flows over an impingement plate, with water evaporating. The water vapour is drawn off. When a measurement probe in the line detects a sufficiently low water content, the largely dewatered sludge is discharged to a stock tank. When the liquid level in the vessel drops due to the evaporation of water and the discharge of dewatered sludge, more untreated sludge is pumped in so that there is always a minimum quantity of sludge in the vessel.

Pitch is a viscoelastic polymer that remains after distilling fuel gas and fuel oil from coal or crude oil. When the volatile substances included in the pitch are removed, the mechanical bonding strength is modified into a precursor to obtain valuable industrial materials such as carbon fiber, carbon heat sink, and carbon conductor with excellent physical properties such as thermal conductivity and electrical conductivity. The conventional pitch reformer wastes a lot of energy and manpower by filling pitch into a reforming container, heating it to a high temperature, removing volatile substances, cooling it to a certain temperature, discharging it, opening the container, and refilling the raw pitch to reform it. The specific gravity of pitch increases as volatile substances are removed, and when applied heat is consumed to evaporate volatile substances, a constant evaporation temperature is maintained and the temperature rises when all volatile substances are removed. And when the pitch suddenly comes into contact with a high temperature, it is carbonized and becomes a solid before the volatile material evaporates. Solidified carbon does not melt even at a temperature of 3000 degrees and does not dissolve in solvents such as toluene and quinoline. A reforming means that can greatly save energy and manpower by continuously injecting and reforming the original pitch ...

Multi-layer steam grid for heat and mass transfer in a tailings solvent recovery unit

A grid of pipes for conducting steam at a pressure greater than a vessels' operating pressure and delivering the steam throughout the grid forms the internals for a tailings solvent recovery unit. The delivery of steam throughout the grid aids in maintaining a relatively low partial pressure throughout the vessel to act as a driver for mass transfer. Conducting the steam at the higher pressure through the pipes in the grid permits a surface of the pipes to be heated to a temperature higher than possible in a conventional vessel, increasing the heat transfer to the feed stream which flows through the grid.
