Home / Literatures As a chemical and process engineer who has spent over a decade designing, commissioning, and optimizing resource recovery facilities, I often encounter project developers debating equipment configurations. A recurring dilemma in the planning stage of a waste oil to base oil plant is choosing between core separation and finishing technologies. Specifically, when the…
Home / Literatures The construction and enlargement of a petrochemical refinery is a capital-intensive investment project. To the project owner, EPC contractor, and procurement managers involved, choosing process equipment is no mean feat and is not only about functional requirements but also determines throughputs, thermal efficiency, OPEX, and compliance with safety regulations. Although a modern refinery…
Home / Literatures In today’s unpredictable oil market and growing international push towards ESG compliance, waste oil recycling has evolved from an ecological duty to an extremely profitable industrial business. Among different waste types, refining used motor oil into premium-grade diesel fuel can be considered one of the most profitable industries. There are huge discrepancies…
Home / Literatures In my years of handling industrial waste oil refinery configurations, plus managing the hydroprocessing units, one question keeps popping up, mostly from plant investors and project developers: can we get to Euro VI or Tier 4 sulfur compliance using “regular” acid–clay treatment or low-pressure catalytic cracking? The short, definitive engineering answer is really no….
Home / Literatures Industrial plant operators have relied on selecting lubricants with only machinery preservation in mind for many years. However, today’s increasing waste disposal fees, changing energy prices, and ESG considerations mean that it is essential to follow a dual-objective approach – achieving maximum efficiency while simultaneously guaranteeing that spent lubricant can be recycled….
Home / Literatures As a process engineer specializing in resource recovery refinery setups, I am frequently asked by refinery managers if different hazardous hydrocarbon waste streams can be co-processed. Specifically, operators using the PurePath waste oil to diesel plant want to know if they can combine waste motor oil and pyrolysis oil within the same production…
Running a waste oil recycling plant not only means maintaining a lean headcount and low costs of supplies, but also effective process management, material handling, as well as the most efficient use of energy available, to ensure the operations are well managed to prevent the waste of high production capacities in the name of low margins.
Home / Literatures The increasing demand for sustainable practices in energy and resource management has elevated the importance of refining used motor oil and other waste oils. Used oils, such as spent lubricants, hydraulic oils, transformer oils, and even cooking grease, represent a significant resource for re-refining into valuable products like base oil, biodiesel, and industrial…
Home / Literatures As refinery engineers managing daily operations in a waste oil re-refining plant, the primary technical challenge we address is demonstrating that recycled products match the performance profiles of virgin base oils. Our plant receives tanker loads of feedstock that contain varying amounts of degraded additives, combustion by-products, and mechanical wear metals. The…
Home / Literatures The choice of a waste oil to diesel conversion facility requires more than just cost considerations; it also requires an analysis of basic engineering principles. A viable system should have a high thermal efficiency (over 85%) to reduce operating expenses, as well as thick boiler steel or special-grade stainless steel that can…
