Home / Literatures In the modern industrial waste management and oil refining industries, used engine oil is no longer a troublesome disposal burden but rather a high-value, carbon-rich recycled raw material. Under the dual circumstances of the global circular economy advancement and fluctuations in crude oil prices, large-scale waste oil recycling has become an industrially…
Home / Literatures Hydroprocessing is a critical catalytic process in petroleum refining, engineered to upgrade crude oil fractions by removing contaminants and purifying their chemical composition. Within this category, hydrotreating and hydrocracking serve distinct yet highly complementary roles. Each of these processes, as well as where they overlap, is discussed in-depth in the following sections….
Home / Literatures The global energy market is experiencing increasingly volatile fluctuations, and the profit margins of refineries are constantly changing. For medium-sized and local refineries to survive, they must either increase their daily processing capacity (BPD) or switch to processing cheaper heavy oils. However, building new traditional refineries often involves huge investments, cumbersome approval…
Home / Literatures Lubricating oil is the core component for reducing mechanical friction, minimizing wear, and ensuring the thermal stability of the system. The production of high-quality lubricating oil relies on the refining of crude hydrocarbon raw materials into functional base oils of different viscosities. These raw materials usually come from heavy oils subjected to…
Home / Literatures Used oil re-refining is an industrial recycling process that transforms degraded and contaminated lubricating oils into high-quality base oils that meet or exceed virgin base oil specifications. This process is distinct from rudimentary filtering or burning for energy recovery; it involves complex chemical and thermal engineering designed to separate precise molecular structures. The…
Home / Literatures The global volume of industrial and automotive waste oil represents a significant environmental liability and a distinct economic opportunity. Waste oil recycling is an important part of the hazardous waste management and industrial circular economy by converting degraded lubricants into reusable base oils or fuel fractions. The return on investment (ROI) for this…
Home / Literatures Crude oil, in its continuous extraction from reservoirs, contains various impurities, including water, salts, and heavy metals. The purification of crude oil is the foundational prerequisite before entering atmospheric or vacuum distillation units. As a premier global vendor specializing in Large-to-Medium-Scale Waste & Crude Oil Distillation Plants, PurePath engineers advanced thermal separation…
Home / Literatures Unlike decades ago, when industrial waste oils were a burden to the environment, today, they are a very valuable asset. In view of global requirements on ESG factors, carbon accounting, and fluctuating prices of crude oils, it has become a profitable business to establish a commercial refining plant. Urban oil fields include…
Home / Literatures Look, if you have been running a waste oil recycling plant or managing a lube oil purification system for as long as I have, you already know the hard truth. The waste oil recycling business is getting tougher every single day. Environmental agencies are breathing down your neck, and buyers are rejecting…
Home / Literatures Step inside any cheap oil recycling plant, and two obvious factors tell you the end product is of poor quality – a deep, unstable amber hue that changes color quickly within days, as well as an unmistakable sulfur smell. The failure to ensure color and odor stability is crucial for medium to large-scale…
