What is The Process of Used Oil Refining?

Oil is a valuable resource, no matter your industry, or the industrial process you deal with. Besides, it is an expensive commodity, the purchase of which costs industrialists millions of dollars every year. In such a situation, industrialists must prefer refining used oil and then use it for the appropriate applications.
Re-refining used oil helps you save money, increase process efficiency, and at the same time, contribute to environment conservation. But then, the process of used oil refining also proves crucial in leveraging it to achieve all the said benefits. So, what is the process to re-refine used oil? Here’s the answer.
Oil is a resource that’s prone to the entry of impurities, and contaminants. These anti-oil elements deteriorate the quality of the oil, decrease its efficiency, and add to the maintenance cost of the equipment. Re-refining used oil helps you overcome these challenges through a focused and organized process. So, take a look at re-refining used oil in 5 necessary steps.
  1. Dehydrating the oil to remove the Undesired Water Content
Unwanted water content proves a significant contaminant for oil. So, the process begins with dehydrating the oil to remove water impurities through evaporation. Further, it involves water collection, chemical, and biological treatment of water, and then discharging it.
2. Recovering Lightweight Chemicals
Next, the process comprises extracting lightweight chemicals for reuse. After removing the water, the used oil goes to tall recovery towers. Here, the refining system separates and collects glycol and light fuels. It reprocesses glycol as a finished automotive grade product.
3. Removing Heavy Fuels
The next step is fuel stripping. It involves removing heavier fuels or industrial use. Further, the oil undergoes heat and vacuum process that helps remove middleweight oils. This process generates fuel as a byproduct for industrial heat treatment.
4. Vacuum Distillation
Vacuum distillation involves reclaiming heavy materials for several uses. It removes the heaviest of impurities through several intricate processes. The process comprises vaporizing the used oil in an extreme vacuum and then condensing it.
Later, it involves separating different types of material from the oil. The process yields heavy oil as the byproduct, which proves useful for several industrial applications. One of them includes their use in making asphalt extenders.
5. Removing Final Impurities through Hydro Treatment
This is the final step in used oil refining. It involves treating the remaining oil with hydrogen to elements such as nitrogen, sulphur, heavy metals, chlorine, and other contaminants. But, the step doesn’t limit removing impurities. It also addresses concerns such as the color, odor, and corrosion performance of the oil. Finally, the refining system separates the purified oil by weight.
Conclusion
Finepac Structures is one of the leading industrial solutions providers in India. The company began operations in 1993. Besides used oil refining, Finepac manufactures a range of mass transfer products, mist eliminators, static mixers, and many other products to serve diverse industrial needs. Besides, the company also deals with services such as mass transfer technology, and separation technology.

Gas Dehydration Plant Manufacture And Suplier

Image
The Glycol Dehydration Unit is a reliable, efficient system for removing water from natural gas well streams in order to meet typical pipeline and process specifications. Multiple stages of removal are contained on a single skid-mounted unit, giving you a wide range of options and flexibility to configure the system to your specific application. Finepac Structures manufacture one of the best gas dehydration systems manufacturing in India. We design and supply gas dehydration systems using triethylene glycol (TEG) to absorb water from the gas. High energy recovery and low glycol losses are achieved with dewatering packages and modules in small, lightweight and small footprints. Natural or wet gases can have varying water content, aerosol and droplet sizes, so the TEG gas dehydration system lowers the water dew point and removes solids from the gas. This prevents hydrate formation, condensation or corrosion in the downstream process. Read More Finepac Structures Gas Dehy

Everything about Plastic Random packing for corrosive applications

Image
Earlier known as dumped packing and used popularly in the gas, chemical plants, and refinery  random packing  is traditionally used for the fractional operations. It has been used to increase the tower’s capacity, and therefore it is a cost-effective and efficient solution used from several decades. Its effectiveness is looked in the dehumidification of air where LiCl (lithium chloride) is utilized. With the innovations and new outcomes,  random packing  displays improved products for the new generations. Available in three different varieties (materials) plastic, ceramic, and metals based on different operational temperatures, the optimum utilization is made for the mass and heat transfer.   In addition to better performance benefit, there are many other advantages of random packing.   Below-mentioned is a few more benefits:      - The pressure drop reduction throughout the column - Liquid holdup reduction in the column - Capacity increment at the same efficiency in
