Storage of lubricating oil and disposal of used oil?

Our petrochemical plant is not large; it has few large-scale units, and the lubricating oil is stored directly in barrels. There wasn’t much used oil either, and the workshop dealt with it directly (it was probably taken away). In any case, it’s no longer allowed to be used.

We now uniformly order takeout deliveries; there is no recycling. If recycling were to take place, many of the specifications for the lubricant would no longer be met

Each type of lubricant should have its own dedicated container, and the name of the lubricant contained within it must be indicated on the container to prevent mixing. Used oil or waste should be contained in designated containers until it is disposed of. Be sure to be careful and keep used oil separate from new oil to prevent the new oil from being contaminated. Generally speaking, the contamination of lubricating oil by harmful impurities is more severe than its contamination by other substances, as the impurities in the oil can settle at the bottom of the oil tank or container, reducing the likelihood of them entering the mechanical lubrication system. But when impurities mix into the grease, since they do not settle, they will eventually enter the machinery and lubricators. Several methods for treating used oil: 1. Discard ； 2. Path oilification 3. Incineration 4. Reprocessed lubricating oil. The fourth method is the best approach, as it saves energy and is environmentally friendly.

Reply to 1# shawlyping: The company offers a wide range of lubricants, hydraulic oils, turbine oils, etc. I’m not sure about the best way to store them Is it for use in jars or in barrels? Also, how do people deal with the high fuel consumption? Is it from takeout, or is it filtered and reused with an oil filter? The storage of lubricants must be carried out based on their properties. It is very important that different types of lubricants be stored separately with clear markings; a dedicated storage area can be set up, and the various lubricants can be arranged there in an organized manner. The addition and use of lubricating oil shall be carried out in accordance with the requirements of five fixed parameters and three-level filtration. For used oil, different treatment methods can be chosen depending on the type of oil, the amount present, and its renewability. If a specialized oil filtration machine is used, the oil can be reused; and if there is a large quantity of oil, it is advisable to purchase such a machine for recycling it. As for oil that cannot be reused, it is important to prevent environmental contamination by collecting it in a centralized manner and then selling it for disposal.

These oils can all be sold to manufacturers specialized in the recycling of used oil.

Barreled and canned lubricants should be stored in a warehouse to protect them from weather conditions; lubricants whose containers have been opened must also be stored in a warehouse. Oil drums should be placed lying down, with wooden wedges used at both ends to prevent them from rolling. In addition, the oil tank should be regularly checked for leaks and to ensure that the markings on its surface are clear. If it is necessary to place the barrel upright, it is advisable to turn it upside down with the lid facing downward, or to tilt it slightly, so as to prevent rainwater from accumulating on the surface of the barrel and covering the latch. Water has a negative effect on any lubricant. When extracting oil, the oil barrel should be placed horizontally on a wooden frame at an appropriate height. A faucet should be installed at the lid of the barrel for draining the oil, and a container should be placed under the faucet to prevent spills. Alternatively, place the oil barrel upright, insert the oil pipe into the barrel lid opening, and draw oil using a hand pump. Temperatures that are too low or too high have an adverse effect on lubricants; therefore, it is not advisable to store lubricants in places that are either too cold or too hot for extended periods of time. Hydraulic oil should be stored in a clean, well-ventilated indoor area that meets safety requirements; if the unopened oil containers are placed outdoors, the following rules must be followed: ① The containers should be placed on their sides, with wooden blocks or sliding racks used to support them, and the bottom surface should be kept clean to prevent accumulation of debris. ②To prevent a high probability of contamination, it is strictly prohibited to make a large hole in the top of the oil dipstick or to remove the upper end entirely. Regarding used oil, as mentioned above, different treatment methods can be chosen depending on the type of oil, the quantity involved, and its recyclability. If the amount is small, it should first be collected together and then sold for processing.

Sold externally by suppliers, usually recycled manufacturers

The main requirements for the transportation and storage of lubricants are as follows: Barrel-packed and tank-packed lubricants should, where possible, be stored in warehouses to protect them from weather conditions. Unsealed lubricating oil must be stored in a warehouse. Oil drums should be placed in a horizontal position, with wooden wedges used at both ends to prevent them from rolling. In addition, the oil tank should be regularly checked for leaks and to ensure that the markings on its surface are clear. If the barrel is to be placed upright, it is advisable to turn it upside down with the lid facing downward, or to tilt it slightly, so as to prevent rainwater from accumulating on the surface of the barrel and covering the plug. Water has a negative effect on any lubricant. On the surface, it seems difficult for moisture to penetrate through a sealed barrel lid and enter the oil barrel. However, oil barrels stored outdoors are exposed to the scorching sun during the day and cooler temperatures at night; this expansion and contraction due to temperature changes affects the pressure of the air inside the barrel. It is slightly above atmospheric pressure during the day, and approaches a vacuum at night. This change in pressure between day and night creates a \"breathing\" effect: during the day, some gas is \"exhaled\" from the tank, while at night air is \"inhaled\" into the tank. If the tank lid is submerged in water, moisture will inevitably enter the tank along with the air. Over time, the amount of water mixed in with the oil can become quite significant. When bulk oil is stored in tanks, it is inevitable that condensate water and contaminants will seep in, eventually accumulating at the bottom of the tank to form a sludge-like substance that contaminates the lubricating oil. Therefore, the lubricant that has been opened should be used as soon as possible to avoid affecting its quality. Temperature has a greater impact on grease than on lubricating oil; long-term exposure to high temperatures (such as direct sunlight) can cause the oil components in the grease to separate. Therefore, grease should be stored in a warehouse, with the container placed upright so that the opening faces upward. Temperatures that are too low or too high have an adverse effect on lubricants; therefore, it is not advisable to store lubricants for long periods in places that are either too cold or too hot. Different oil products should be stored separately, with clear markings indicating their name, grade, quality level, quantity, and date of entry, to avoid mistakes during shipment. Requirements for the transportation and storage of automotive chemicals and beauty products: Pay attention to the precautions indicated on the corresponding Chinese labels of the products. Some chemical products contain flammable components such as kerosene, so it is necessary to avoid exposure to high temperatures and keep them away from heat sources. Preventing lubricants from harming health: Many petroleum products are harmful to the human body; if they come into contact with the skin and are not cleaned off promptly, they can cause mild conditions such as dermatitis or bumps, or more severe issues like rashes or skin tumors. If it gets into the mouth or is inhaled, it can cause gastrointestinal problems or pneumonia in mild cases; in severe cases, it may lead to cancer. Therefore, care should be taken to avoid getting oil on food, to prevent it from entering the respiratory tract, and to avoid having oil all over one’s body or on the floor. This not only results in waste but also undermines personal hygiene. Animal tests have shown that refined mineral oil lubricants have low toxicity, but the hazard of lubricants with additives increases, so caution is necessary. Even if new oil is non-toxic, deterioration and contamination during use can increase its harmfulness; therefore, care must be taken to avoid contact with the skin, and it must especially not be inhaled or ingested. If it comes into contact with the skin accidentally, rinse it off immediately with clean water. Treatment of used oil: The lubricating oil that has expired can no longer be used and must be treated as waste oil. This waste oil should be disposed of properly to prevent environmental pollution. Never pour used products down the drain, into tunnels or rivers, or discard them carelessly. These used oils should be collected and sent to a dedicated used oil treatment center for centralized processing; they can be reused or burned under controlled conditions, or they can also be incinerated. Buckets or bottles containing lubricating oil should not be discarded carelessly; they must be disposed of properly to prevent any negative impact on the environment.

Lubricating oil can carbonize after use. Sludge is formed, the acid value increases, and it can no longer be used. If there is no regeneration device, it can’t be used.

All the lubricants in our workshop are supplied in barrels and are stored uniformly in a clean oil warehouse； Personally, I think it’s not necessary to put it into the tank if there isn’t much lubricant available, as impurities can easily get introduced during that process ； As for the used lubricating oil, once a request is made to dispose of it, the company handles it centrally. Due to the large number of imported equipment in the workshop, it is absolutely forbidden to reuse such waste oil! Answer completed! :victory:
