Description

FIELD OF THE INVENTION
[001] The present invention, generally relates to oil sludge based pellets and a method for forming such oil sludge based pellets.
BACKGROUND OF THE INVENTION
[002] In the past one and one -half decades, the refinery industries have significantly affected the environment with its by-product i.e. oil sludge. During the process of crude oil refining, large amounts of oil sludge is produced, which contains oil, benzenes, phenols, and other odorous and toxic substances. Globally, utilization of the oil sludge from the refining of crude oil is an environmental time bomb as many of the constituents therein are of hazardous nature. Petroleum sludge is classified as hazardous waste (usually due to its oil content) and in most cases, it is also classified as a liquid, which means it cannot be disposed of directly to a landfill. The effective remediation of oil sludge has become a worldwide problem due to its hazardous nature and increasing production quantity around the world.
[003] Incineration of oil sludge has been proposed but is not an attractive method of disposal due the high water and oil content. Many other methods such as filtration, thermal treatments etc. are also not suitable for the oil sludge treatment because of its semisolid nature and high amount of oil as well as water. [004] Oil sludge also cannot be treated by any waste treatment method because of its high oil and solid content, and having high COD/BOD. Moreover, long storage of oil sludge can contaminate the ground water by the leakage of oil and the surrounding air. It is also a major risk hazard for fires, explosions, poisoning of the food chain and destruction of green areas. The ash value of the oily sludge is approximately 60%, which again makes it a dangerous product for disposal and effective use.
[005] Because of the hazardous nature of oil sludge and lack of proper disposal of excess sludge, the disposal which will be further restricted in the near future; increased attention has been turned to look into potential technology for oil sludge treatment / use. Therefore, there exists the need for a better solution for either treatment or use of the oil sludge.
OBJECTS OF THE INVENTION
[006] It is an object of the present invention to provide an oil based bio fuel pellets that are durable, compact and easily transportable.
[007] It is another object of the present invention to provide a method for the production of oil sludge based Bio-fuel pellets.
[008] It is another object of the present invention to provide a marketable fuel using the energy entrapped in the oil sludge. [009] It is another object of the present invention to provide a process for conversion of heavy oil and water content of the oil sludge into a usable residue without segregation.
[0010] It is yet another object of the present invention to provide a process to use the refinery oil sludge to manufacture a easily usable and marketable product, without any segregation or further process.
SUMMARY OF THE INVENTION
[0011] The present invention provides an oil based bio fuel pellets, comprising oil sludge and biomass. The fuel pellets are durable, compact and hard enough to be transported easily.
[0012] Further, the present invention discloses a method for the production of bio-fuel pellets using oil sludge. The bio-fuel pellets include oily sludge and biomass. The cellulose and lignin based biomass may be utilized for the bio fuel pellet production. The biomass material is in a ground particulate material form, which forms a majority of a total mass of the fuel product. The proportion of biomass may vary from 80%-50% depending upon the water content of oil sludge, type of biomass used and application of the pellets more preferably comprises 65-70 % of the total mass of the fuel pellet. Oil sludge content of the total mass of the fuel pellet may vary from 20% to 50%. Biomass absorbs the excess water content of oil sludge and embodies with its oily content.
[0013] Furthermore, the present invention provides a method to convert a highly combustible product as well as water pollutive residue i.e. oil sludge into a proprietary bio-fuel pellet product without the severe toxic emissions/water pollution or further segregation. Invented method provides a very cost effective means of using oil sludge in its original form because the oil content of the waste oil sludge is used to generate the energy.

[0017] The embodiments of the invention will now be described herein, with reference to the accompanying examples and drawings. It will be understood by those skilled in the art that the foregoing general description and the following detailed description are exemplary and explanatory of the invention and are not intended to be restrictive thereof.
[0018] Fig. 1 illustrates oil sludge based bio fuel pellets 100, according to an embodiment of the invention; the oil sludge based fuel pellets 100 include the oil sludge and biomass (not shown in the figure). The biomass material may comprise approximately 80% to 50 % of the total mass of the fuel product pellets, depending upon the water content of oil sludge, type of biomass used and application of the pellets and more preferably comprises 65-80 % of the total mass of the fuel pellet. Oil sludge content of the total mass of the fuel pellet may vary from 20% to 50%.
[0019] Various concentration combinations of biomass material and oil sludge were tested in order to obtain oil sludge based fuel pellets (Table 1):
Figure imgf000008_0001
[0020] In an embodiment of the invention, oil sludge produced during the process of crude oil refining which contains oil, benzenes, phenols, and other odorous with some toxic substances. The percentage of water, oil and other components may vary in the oil sludge depending upon the refinery process.
[0021] In another embodiment of the invention, biomass may include all forms of renewable energy that are derived from plant materials which are based on either cellulose or lignin such as wood and wood waste, agricultural crops, etc.
[0022] In yet another embodiment of the invention, the oil sludge bio fuel pellets 100 may vary in size, shape and weight. The oil sludge based fuel pellets 100 may be in any of the shape such as, circular, rectangular, triangle, square etc. In an example, oil sludge based fuel pellets 100 are cylindrical in shape (Fig. 1).
[0023] Fig. 2 illustrates a method 200 for manufacturing the oil sludge based pellets, according to an embodiment of the present invention. The method 200 begins at step 202, where in, grinding of biomass material is done through an appropriate grinder in order to obtain ground particulate form of biomass. This is a key element to ensure proper integration with the oil sludge. The requisite conditioning of the biomass material is important in terms of moisture, particle size, energy value, inherent ash value and fusion characteristics. At step 204, drying of ground biomass material is performed to provide dried biomass for the step 206. At step 206, the ground biomass material is mixed with oil sludge in different concentration ratios.
[0024] The biomass and oil sludge weight percent ratio may vary from 80 to 40 and 20 to 60, respectively. At step 208, blending of the mixture of biomass and oil sludge is performed to obtain fine mixture for pellet formation. The blending is homogenized the combined residues for enabling proper pelleting. Further at step 210, pelleting of the mixture of biomass and oil sludge is performed by the pellet press to obtain fuel pellets. The bio fuel based oil sludge pellets are extruded through a proprietary machine which allows the pellets to be formed from this combination of materials. The required diameter of the pellets and its durability to conform the EU DIN standards are dependent upon the die material, die design to extrude the pellets, the effective channel length, the excess diameter of the die at the entry point of material as well as the compression ratio in the channel length of the die, its thickness and the release of the pellets from the die. The released pellets are hot at between 70-80 °C and need to be cooled immediately in a cooler cum screen to achieve the requisite durability and hardness in transport, handling and use of the said oil sludge based pellets.
[0025] Aspects of the present subject matter are described herein with reference to flowchart illustrations and/or block diagrams of methods and the composition of the product according to embodiments of the subject matter.
[0026] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. It will be apparent to those skilled in the art that various modifications and variations can be made in the products and methods of the present invention without departing from the spirit or scope of the invention.
