Waste Oil Recycling

Importance of Mineral Oil Recycling: The world experienced the industrial revolution in the last two centuries and left the automotive industry. Petroleum products include fuel, coolant, maintenance, cleaning products, lubrication, etc. Petroleum is a powerful and non-renewable energy source, creating demand for use by introducing many simple and complex machinery, equipment, commercial and non-commercial vehicles. energy. We have limited stocks. If we want future generations to benefit from non-renewable energy sources as we do, we must act now.

Instead of destroying used petroleum products, we need to re-refine them. These oils are contaminated during their service life by undesirable factors such as oil, water, unburned fuel, polymerized carbon chain, degraded additives, dirt, oxidized surface metal particles, or wear of the combustion chamber or engine surface gears and other mechanical parts. Because of these impurities, the oil becomes a black old oil that is no longer suitable for use as a lubricant and must be replaced. Currently, most people dispose of this black oil in manhole waters, landfills, lakes, streams or seas. Black oil is a poisonous compound. One drop of black oil can contaminate 1000 liters of water. If we re-refine this black oil, we can benefit from the availability of petroleum products in the long run.

1- PRE-FILTERING UNIT

Used mineral oil is purified from solids (waste, fabrics, metal dust, dirt particles) by passing through the solid waste filter.

Waste oils are transferred to the chemical pre-treatment tank.

Depending on the nature of the used oil, one of two processes is carried out in the pre-treatment tank; First, the used oil is heated to 40-50 degrees Celsius and rested after opening the connections. Second, although rare, waste oil is heated to 40 – 50℃, mixed with weak bases (ppm) and aged. Waste oil in the pre-treatment tank is transferred to the water and solvent removal flash reactor.

2- WATER AND SOLVENT DISCHARGE UNIT

Waste oil is transferred to water and solvent removal unit, water in waste oil and light volatile hydrocarbons are evaporated, heated up to 140-200℃ depending on condition waste and condensate passing through the heat exchanger. In the flash reactor, the oil is collected in the distillate tanks and the waste oil removal process takes place. Waste oil at 140-200 ℃, removed from water and light volatile hydrocarbons in its structure, is transferred from the preliminary dehydration tank to the isolated intermediate collection tank. The oil in the intermediate collection tank is transferred to the distillation column unit (asphalt and fractionation).

3- ASPHALT REMOVAL AND SEPARATION UNIT

Waste oil in the intermediate collection tank is transferred to the multi-stage distillation column. The distillation column operates on the principle of boiling temperature difference. Waste oils, which carry out a continuous transfer between the furnace and the multistage column, are divided into three types. The light oils first evaporate and liquefy on the upper plate of the column, pass through the heat exchanger and are collected in the distillate tank and are called crude oil. Intermediate oils are the second oils that evaporate and liquefy in the center plate of the column, pass through the heat exchanger and accumulate in the distillation tank and are called crude oil. Heavy oils are the last oils that evaporate and liquefy on the bottom plate of the column, pass through the heat exchanger and are collected in the distillation tank and are called crude oil. The crude oils collected in the distillate tanks are transferred to the base oil filtration unit. While the base oils are fractionated in the distillation column unit, the bottoms product (asphalt) is transferred from the bottoms product (asphalt) unit to the distillation tank storage tanks. It is reserved for a vacuum circulation pump.

4- BASIC OIL FILTRATION UNIT

The raw oil collected in the distillate tank passes through the base oil filtration unit, and the unwanted substances and waste mineral oils are filtered through the solid waste filter and are purified from solid matter (waste , fabrics, metal parts, etc.) from used oils. transferred to the chemical pre-treatment tank.

Hydrogenation, combined with vacuum drying and filtration, is the most comprehensive and advanced process technology for Waste Mineral Oil Recycling. In the hydrogenation process, hydrogen gas reacts with sulfur, nitrogen, chlorine and other unsaturated compounds in the waste oil, producing a stable product with low sulfur concentration and insulating properties superior.

5 – HOOKAH UNIT and FIREPLACE

The reactor gas cannot liquefy the entire heat exchanger. The gas passing through the heat exchanger without condensation enters the hookah tank after passing through the distillate tanks. The gas enters the hookah tank filled with a sufficient amount of water from the bottom and is washed out with water. The gas passing through the water wash condenses to a minute amount and liquefies and forms a thin layer on the hookah. The non-liquefied gas is burned in the incinerator. As hookah water liquefies hydrocarbon-containing gases over time, it loses its washing function. While the installation is in continuous operation, hookah water that loses its quality is changed every 60 days.

Incinerator: Mineral Oil Recycling
The waste gas from the hookah tank will come out of the incinerator. Combustion waste gases will be burned with an industrial thermal magnet automatic igniter. It works with the cigarette lighter automation system and turns on automatically.
