Definitions
- This invention relates to the treatment of petroleum refinery sludges, and particularly to a process for the treatment of such sludges to produce a coke-like product useful as a petroleum coke.
- oily sludges are produced as a waste product.
- Such sludges are generally characterized as three-phase, multi-component, organic sludges containing water, oil, and solids.
- the oil component is typically one or more liquid hydrocarbon fractions of petroleum ranging from gasoline components to heavy oils.
- the solids component may comprise high boiling organic materials, or carbonaceous solids, and may contain metallic and other inorganic materials.
- the water is present as a result of the use of water for process cooling, cleaning, or the like. Because of the presence of hazardous materials in such sludges, their disposal presents a problem for the petroleum refiner.
- Such sludges are considered hazardous because of the presence of metals such as lead and chromium, or organic materials such as benzene, cresols, phenol and the like.
- various alternative technologies have been proposed. These include solvent extraction, mechanical dewatering, thermal treatment, chemical fixation and stabilization (mixing the oily sludge with a solidifying agent such as cement).
- U.S. Patent No. 3,917,564 discloses a processing technique wherein refinery sludges are used as a quench medium in a delayed coking process wherein the sludge is converted into petroleum coke at a pressure and temperature which cause the hydrocarbons in the sludge to crack and/or polymerize to form coke. While this latter technique may be sometime satisfactory, not all petroleum refineries include a delayed coxer. Further, if the sludge is, for example, very high in undesirable metals and ash, the resulting coke product may not be satisfactory for use as coke.
- U.S. Patent No. 4.101,414 discloses a process wherein used lubricating oil is predistilled in a steam-stripping still and the predistilled used oil is then subjected to vacuum distillation at a temperature below the cracking temperature of the oil to effect a separation of the used lubricating oil from a residue concentrate byproduct of heavy lube oil hydrocarbons and additives.
- the concentrate product formed during the vacuum distillation step includes heavy lube hydrocarbons, additives, metals, metal compounds and the like and is stated to be useful as a lubrication grease.
- Another object of the invention is such a process which permits treatment of petroleum refinery sludges on-site and leaves non-hazardous waste.
- a further object of the present invention is such a process which is simple in operation, does not require substantial and elaborate equipment for carrying out the process, which equipment may be portable, if desired.
- An advantage of the present invention is that it does not require extraneous steam for processing and, additionally, a cooling medium, such as cooling water, is not required to cool the coke-like product produced by the process.
- a further advantage of the invention is that the resulting coke-like product, while meeting environmental requirements, has sufficient BTU content for it to qualify as a low grade petroleum coke.
- a process for treating petroleum refinery sludge to produce a coke-like product comprises forming a feed stream of an oily petroleum refinery sludge containing organic solid material boiling above 1000°F and a preselected amount of water; introducing said feed stream into a sludge drier; heating the feed stream in said drier to a temperature above the boiling point of water and below the temperature at which thermal cracking of hydrocarbons in the feed stream occurs; maintaining the heated feed stream in a non-oxidative atmosphere for a time sufficient for the water in the feed stream to form sream and for the steam to strip any light hydrocarbons from said solid material in the feed stream; separating a hydrocarbon/water vapor stream from said solid material; and recovering a solid, coke-like residue product.
- a preferred embodiment of the invention includes the step of pre-treating the feed-stream prior to the heating step to adjust the water content to a level providing sufficient steam for stripping light hydrocarbons from the solids while minimizing the heat required to vaporize the water in the feed-stream.
- hot flue gases may be used to produce steam for indirect heating of the feed-stream in equipment similar to that used as the sludge drier.
- the feed-stream for the present process is one or more petroleum refinery sludges collected at the petroleum refinery at which the process is to be practiced.
- the petroluem refinery sludges typically are three-phase, multi-component sludges, usually containing about 20-90 wt.% water, about 5-40 wt.% oil and about 5-35 wt.% solids.
- the oil portion may include volatile hydrocarbons such as various aliphatic, heterocyclic and aromatic compounds, as well as other organic compounds used or produced in the refinery operation.
- organic compounds may be, for example, organic acids, such as phenols and cresols.
- the solids portion of the sludge may include inorganic particulates, such as silica, alumina and the like, metals and metallic compounds, and high boiling organic compounds, e.g., those boiling above about 1000°F, which are normally solid in ambient temperatures.
- the sludge should contain a sufficient amount of such high boiling organic solids to make it feasible to operate the process for this purpose.
- the sludge does not contain large amounts of hazardous constituents such as lead, chromium, or the like.
- the sludge does not contain significant amounts of light hydrocarbons, such as gasoline, naphtha, or kerosene, since they will not usually provide enough residual energy and they are quickly volatilized because of their low boiling points. Concentration of such light materials that will not recondense with typical cooling water at standard pressure may present an explosion hazard and, therefore, they are not desirable.
- crude petroleum is not preferred in the feed-stream when it contains a high concentration of non-condensable hydrocarbons, it may be included if appropriate equipment is provided.
- the moisture content of the feed-stream is very important for the practice of the present process.
- the feed-stream should contain sufficient water to provide steam for adequately stripping light hydrocarbons and the like from the solids contained in the feed-stream. If, however, the feed-stream contains water in an amount greater than that required for the desired stripping, additional heat will be required to vaporize the water and this will reduce the predicted capacity of the equipment. For example, it was found that a sludge containing 15% water, 30% oil, and 55% solids could be processed at a predicted throughput of 6 tons per hour; however, another sludge containing 40% water, 9% oil and 51% solids could be processed at a capacity of only 3.84 tons per hour.
- the sludge to be treated has an inadequate moisture content, of course, water can be added to the sludge to adjust the water content of the feed-stream to a satisfactory level.
- the sludge may be dewatered by the use of centrifuges, filter presses or the like. It may be desirable to use chemicals, such as demulsifiers and/or polymers, all of which may be used to reduce the heat demand and increase the throughput so as to reduce operating costs.
- a feed-stream 10 is formed from one or more of the petroleum refinery sludges described above and passed into a solids concentration unit 12 such as a filter press wherein oil and water are separated from the solids in the feed-stream to provide a solids concentrate having a water content between about 5% and about 25%, based upon the total weight of the pretreated sludge.
- a solids concentration unit 12 such as a filter press wherein oil and water are separated from the solids in the feed-stream to provide a solids concentrate having a water content between about 5% and about 25%, based upon the total weight of the pretreated sludge.
- the solids concentrate is passed by way of line 14 to a pre-drier unit 16 which preferrably is a screw flight drier of the type well known in the art.
- a screw flight drier is a hollow-screw jacketed-trough thermal drier wherein a solid material to be processed is moved through the drier by a rotating screw mechanism and a heat transfer fluid is circulated through the hollow screw and the jacket trough to heat the material passing through the drier.
- the pre-heated solids are passed by line 18 to a thermal desorber, or sludge drier 20, which also is preferrably a screw flight drier of the type described above.
- a suitable heat transfer fluid such as Dowtherm, or another oil satisfactory for this purpose is heated to the desired temperature by heater 22 and circulated by a circulating pump (not shown) through thermal desorber 20 by lines 24 and 26.
- heater 22 is fired by a refinery fuel, for example, refinery gas, and the combustion thereof produces a hot flue gas which is passed via line 28 through heat exchanger 30 to vaporize water therein.
- the steam is then passed by line 32 to the predrier 16 and circulated therethrough as the heat medium to preheat the solids concentrate.
- sludge drier 20 the solids concentrate is heared to a temperature above the boiling point of water and maintained in a non-oxidative atmosphere.
- the residence time in sludge drier 20 should be long enough for the water contained in the solids concentrate to vaporize and permit the resulting steam to strip the remaining light hydrocarbons from the solids in the feed stream to leave a solid residue.
- Vapors containing light hydrocarbons and water are removed from sludge drier 20 via line 34.
- the sludge drier 20 may be operated under a slight vacuum sufficient to draw off the vapors, or it may be operated under a slight pressure sufficient to force the vapors out of the system through line 34.
- These vapors are passed through a condenser 35 and the condensed water and hydrocarbons are collecte and separated in an accumulator (not shown) and recovered.
- Non-condensable vapors exit through relief line 37 provided with a relief valve 37a and are routed to the refinery flare (not shown)
- the feed-stream passed through sludge drier 20 is not heated to a temperature at which thermal cracking of hydrocarbons in the feed-stream occurs. First, this would tend to produce coke which has a tendency to foul the system. Secondly, at temperatures below the thermal cracking temperature no free radicals are formed, preventing any non-condensables from being formed. Additionally, processing below the thermal cracking temperature level, e.g., less than about 660°F, prevents the same free radicals from, in a secondary reaction, joining together to form larger molecules.
- a rotary valve 36 of the type well known in the art is used in the line 38 connected to the solid discharge port of sludge drier 20.
- the valve 36 is divided into several segments so that solid material may be transported out of the vessel without a release of vapors to the atmosphere. As the valve rotates, it seals the following and leading vanes so that at no time is there an uninterrupted path for discharging vapors.
- the valve 36 is located far enough from the bottom of the sludge drier 20 to prevent liquids from leaving with the produced solid residue.
- An outlet port on the bottom of the discharge end of sludge drier 20 preferably is fitted with a fine mesh screen to permit the draining off of liquids that, for any reason, fail to be vaporized or converted to a solid.
- Such liquid can be recycled back to the inlet line 18 ahead of the feed-stream flowing into the sludge drier 20.
- the volume of any recycled liquids can be measured by any convenient means of liquid flow measurement. When flow is detected, the operator can be notified and the liquid can then be fed back to the feed line 18.
- a feed hopper, or bin, 40 located in line 14 ahead of the pre-drier 16 to provide a surge vessel providing a continuous feed-stream to the pre-drier 16.
- the de-watered material can be placed into a bin, ideally between about 5 and about 7 cubic yard capacity, by any well known conveying device, such as an articulated conveyor belt (not shown).
- the bin, or hopper should be located so that material from the bin gravity feeds into the pre-drier 16, is then conveyed through the drier, and exits at the end away from the bin.
- a vibrating mechanism 41 typically similar to an oil field shaker screen, to prevent bridging and plugging of the feed hopper.
- the heated solids exiting pre-drier 16 will typically be at a temperature about 100°F, but not usually above 212°F.
- line 18 should be vapor tight from pre-drier 16 to the inlet of sludge drier 20 to prevent emission of hydrocarbon vapors to the atmosphere.
- Thermocouples should be placed at the exit of both pre-drier 16 and sludge drier 20, as well as in the lines 24, 26 and 32, transporting the heat transfer fluids to the sludge drier 20 and pre-drier 16, respectively. This permits a record of the temperatures so that a continuous heat balance can be maintained.
- the above described technique for the thermal processing of the petroluem refinery sludges at low temperature to produce a coke like product suitable for use as low grade petroluem coke provides a number of advantages relative to other known forms of disposing of such sludges.
- the process is cheaper, particularly in a service mode, since the cost of a compressor to capture, liquify and contain produced non-condensables is eliminated.
- the equipment used in the practice of the process can be portable and does not require additional complicated and expensive equipment.
- Another important advantage is that, since the process operates below the thermal cracking temperature, coking is avoided, preventing a fouling problem, usually caused by the feed stock being passed directly over a heated surface. As explained above, this prevents the formation of free radicals leading to the formation of coke deposits on the interior of the processing equipment and eliminates the need for breaker bars to scrape off accumulated hydrocarbons from the interior walls of the processing equipment. Also, expensive equipment for collecting and condensing gases is not required.
