Definitions
- the invention relates to a method for the thermal treatment of water-containing oil sludge or the like.
- oil-containing sludges that occur when drilling for petroleum and natural gas and in the production of petroleum. Furthermore, these can be sludge-like residues that originate in particular from the oil industry or refineries. Soil contamination from oil or similar substances, such as tar products, may be present. Finally, this includes soil contamination from other industries with oils, tars, pitches, hydrocarbons and the like. ⁇ . understood that are more or less water-containing.
- the invention is based on the object a process for the thermal treatment of heterogeneous water-containing oil sludge or the like show, the reliable and wherein accomplished with a reasonable effort problem ⁇ a los deponiercopyer residue "may.
- the process according to the invention is based on the complete conversion of oil sludge moldings into process gas and subsequent combustion of the process gas using heat, the environmental problem of dioxin also being mastered by targeted thermal treatment of the process gases generated in the gasifier.
- the oil sludge is mixed intensively with a carbonaceous additive.
- a carbonaceous additive should primarily be reactive coke.
- carbon-containing ashes or residues from thermal processes can also be added.
- such an additive is understood to mean biomass and fossil carbon carriers with and without thermal pretreatment (e.g. degassing / smoldering / coking).
- a fine-grained aggregate is used here, which performs several functions in the mixture.
- One function is that the additive compensates for the possibly considerable moisture content of the oil sludge of up to 40 to 50% by weight, so that the product formed after the mixture of additive and oil sludge has been mixed, i.e. the carbon-oil sludge mixture, without additional drying is immediately usable for gasification.
- the small-grain aggregate ensures that the gasification of the oil sludge proceeds in a controlled manner and that the desired free-flowing inert residue can be generated if practically nothing or only a little combustible is contained in the oil sludge.
- the aggregate therefore not only takes on the role of an additional fuel supplier, but above all the task of removing the moisture from the oil sludge with the help of its large surface, thereby making it stable and malleable and improving its gasification behavior.
- the mixing of the carbonaceous additive with the oil sludge to form a mixture of carbon and oil sludge also leads to an equalization of the oil sludge and, furthermore, to the fact that the content of petroleum or other combustible substances present in the oil sludge is uniformly distributed in the end product.
- the coke should be given the opportunity to absorb and bind the "free" water contained in the oil sludge, so that the consistency of the finished mixture is crumbly-dry and no longer sticky-impermeable.
- the process gas generated during ascending gasification can be drawn off from a middle height range above the hottest reactor zones and then led downward along the outer wall sections of the hottest reactor zones into a combustion chamber.
- the process gas is then partially burned in this combustion chamber with the addition of air. Subsequently, the process gas is transferred to a flame channel and completely converted into flue gas here with a further air supply with controlled cracking and combustion.
- the process gas which is still rich in condensate, is drawn off hot and led downward into a combustion chamber along outer wall sections of the hottest reactor zones, it can mix even more intensively without suffering heat loss. Rather, it is heated up further.
- the hot process gas After the hot process gas has passed the outer wall sections of the hottest reactor zones, it reaches a combustion chamber, where it is partially combusted at temperatures of around 400 ° C.
- the tarry and oily constituents of the process gas are then cracked at temperatures of 950 ° C. and higher to non-condensable low-molecular compounds, mainly gases.
- This gas mainly consists of the components C0 2 »CO, H ⁇ , CH 4 and N 2 .
- the lower calorific value of the gas is between 950 and 1150 kcal / Nm 3 .
- a three-stage system of gas combustion with increasing temperatures up to approximately 1200 ° C. is thus ensured (- guidance of the process gas along the hottest reactor zones - combustion chamber - flame channel -) that also from the problematic fuels in question » that is, the oil sludge, always ' only completely burned-out flue gases are produced which are free of odorous substances and unburned gases or hydrocarbons as well as other pollutants.
- the flue gases can finally be transferred from the flame channel into a boiler forming part of a heating system.
- the flue gases can also be fed to other facilities for heat recovery. This is understood only to mean, for example, devices for generating steam or for drying and firing bricks or the like.
- the method according to the invention therefore not only has the advantage that the problematic oil sludge to be treated is completely converted into a free-flowing inert residue which is problem-free and environmentally friendly, for. B. can be used as a building material or concrete aggregate or can be disposed of by emplacement on a depository, but also the advantage that the heat generated during the gasification process can be used effectively.

Abstract
On dépose actuellement les crasses aqueuses d'huile dans des décharges spéciales de déchets. On a également envisagé leur combustion, mais celle-ci est liée à d'autres problèmes de pollution. Selon l'invention, un aggrégat carboné est mélangé à la crasse d'huile et le mélange est pressé pour former des briquettes. Ces briquettes sont alors gazéifiées, et le gaz produit par ce processus est complètement transformé en gaz de fumée par crackage et combustion contrôlés. Finalement, le gaz de fumée peut être fourni à une installation de récupération thermique.Aqueous oily dross is currently being deposited in special waste landfills. Their combustion has also been considered, but this is linked to other pollution problems. According to the invention, a carbonaceous aggregate is mixed with the grime oil and the mixture is pressed to form briquettes. These briquettes are then gasified, and the gas produced by this process is completely transformed into flue gas by controlled cracking and combustion. Finally, the flue gas can be supplied to a thermal recovery plant.
