4 SLMAC WASTE/USED LUBE OIL REFINING PROCESS ZERO CLAY TECHNOLOGY (DE METALIZE + DE ASH + DE CARBON) SLMAC is an indigenous used lube oil products. Some of its astute characteristics are: SLMAC uses No Hazardous or Banned chemicals. SLMAC removes Halogens, heavy metals, Sulfur and oxidized products and bring them within permissible limits. SLMAC yields high quality base stock with better Color and Oxidation Stability with ALMOST ZERO CLAY. SLMAC Save Complete process Energy Consumption by 30%, as compared to other Processes. SLMAC Prevents equipment fouling, corrosion, and coking of process equipment such as heat exchangers and vacuum system. SLMAC process separates bottom from feedstock which can be used as asphalt extender, rubber process oil, base for black printing ink, axle grease manufacturing and as rust proofing compound. 4

5 WASTE LUBE OIL (WLO) Lube oil is a fraction of crude oil distillate which is generally taken for granted by us. But, vehicle numbers are at a high and are still rocketing. The Lube Oil s quality during its tenure is deterred mainly by contaminants such as Cotton Waste, Bolt, Nuts, metals (in ppm), free and emulsified water. These contaminants in the used lube oil may be treated and converted to a cleaner and usable form by not involving any chemical treatment via our method. Various Sources of Used Oil Include: Car & locomotive Gear boxes and engines. Generators. Hydraulic cylinders of Heavy & Light machinery. Electrical Transformers. Any Lube oil application machinery of industry. Chief oil contaminants may be categorized under various headings such as: o COMBUSTION PRODUCTS 5

8 SCHEMATICS AND PROCESS FLOW DIAGRAMS a. PROCESS PROFILE A proposal for processing used lube oil, mineral oils and industrial oils, using high vacuum molecular distillation technology is presented here. The various steps involved in the projects are given below: Step # 1: Step#2: Step# 3: The used & mineral oils are pre-treated with two types of polymer, which will flocculate the carbon sludge substantially and separated by centrifuging/filtering The used & mineral oil from the previous step is passed through phase separators, coalescer filters to remove free and emulsified water. These used and mineral oils are passed through a thin film evaporator, under medium vacuum and temperature, to remove, diesel, dissolved water if any and some lighter fractions Step# 4: The undistilled used and mineral oils are passed through a molecular distillation Plant, under higher vacuum and temperature, to distill off lighter oil (approximately equal to SAE 20 in viscosity). Step#5: The undistilled used and mineral oils subjected to high vacuum, high temperature in an induction heated molecular distillation plant. The distilled oil will have a viscosity of about SAE 40 at ambient. Step #6: The distilled oils are bleached with very less quantity of active clay to get very light colored base oils, to be blended with additives to get finished oils for the automotive and industrial applications. Step# 7: The final residue is semi solid at ambient and can be processed for manufacturing asphalt or briquettes, finished to make offspeck heavy fuel oil or to make greases for slow moving machineries. 8

9 Step# 8: The used clay can be reclaimed, re-activated 3-4 times, by using solvent extraction and high temperature activation process. The entire project can be installed in 6 modular structures and capacities of the plant can be increased later by adding modules b. PROCESS DISCRIPTIONS The following process stage has to be followed to obtain quality base oil as per ministry of petroleum and environments: 1) Pre-treatment: Stripping, Centrifuging 2) Decantation & Dehydration 3) Thin film molecular distillation using high vacuum 4) Bleaching & Neutralization 5) Filtration 6) Blending 7) Waste water treatment plant & Oxidizer to re-use waste & to become environment friendly. 1) Pre-treatment: The used Lubricating oils usually contains aromatics,carbons,heavy particals gets settle,steam stripped & the filtered & clarified using centrifuge. 2) Decantation & Dehydration: The used Lubricating oils usually contains aromatics etc., and free water which can be separated by way of decantation and heating at high temperature to remove emulsified 9

10 water and gas oil i.e., mixed lighter fractionators fuel oils under vacuum heated by thermic fluid heater. 3) Thin film molecular distillation: After decantation and dehydration the used oil will be transferred for high vacuum distillation and taken the distillate out as a distilled oil. And residue will be separated - stored & supplied for further use. 4) Bleaching & Neutralization: After distillation, the treated oil may need very les quantity i.e. not more than 2% activated fuller s earth by volume and it has to be neutralized before taking in for blending of various grade of lubricants. For filtration the spent clay which has been added for neutralization has to be removed through plate and frame filter press as well as centrifuge and thus we obtained the base oil for blending. 5) Blending: The base oil has to be degraded for application of industrial lubricating oil after adding required additives. 10

Hence our process makes sure that all waste products have a minimal impact on the environment. Every byproduct of the process is dealt in the following manner: WASTE RESIDUAL OIL from the Vacuum Distillation Asphalt which is 10 to 15% of the feed can be blended in to Heavy fuel oil, which further can be combusted with specially designed fuel burners. Asphalt can replace expensive Masticating Agents, such as Pine Tar in Various Industrial Rubber Application. Asphaltic residues with inherent Metals and Carbon can also be used in the form of Flap Oil, for mixing with Rubber. Asphaltic residues from our processes can also be used as an additive in tarmac, applied for Road Building. EXTERNAL WATER supply is not required. Any water generated during the distillation process (1200 to 1500 lts) is reutilized in the cooling towers only or for gardening purposes. AIR EMISSIONS emitted by the vacuum system are also oxidized under controlled temperature and environment at 390 C before exhausting to the atmosphere. The other gases exhausted are in the form of combustion OF FUEL for heating, and thermal oxidization of VOC and are as per the following : 26
