Valorization of Lube Oil Waste by Pyrolysis

Energy & Fuels, 1997
Valorization of selected wastes by pyrolysis has been claimed as an alternative to incineration. Lube oil waste, LOW, coming from automotion and industry is a good candidate for valorization via pyrolysis and subsequent utilization of gases and liquids produced. In this paper, the results obtained from pyrolysis of a LOW at temperature from 600 to 700 °

Techno-economic evaluation of waste lube oil rerefining

International Journal of Production Economics, 1996
Abstract This paper discusses the secondary use of used automotive lubricating oils. Current technologies for processing waste lube oil into new lubricants is outlined and the performance features of these products are compared with that of virgin materials. Process technology of Meinken and Mohawk were selected for techno-economic evaluation.

Recent advances in waste lube oils processing technologies

Environmental Progress & Sustainable Energy, 2018
Waste lube oils are classified as hazardous waste due to the metal contents derived from the additives and wear. Most lube oils contain up to 20% of additives including antioxidants, anti‐wear, and de‐foaming agents which are generally used to extend the usage of lube oils and enhance engines performance. The most widely‐used additives contain metal as

Compressor Station Fuel Gas Superheating Using Lube Oil Waste Heat

2004 International Pipeline Conference, Volumes 1, 2, and 3, 2004
Compressor station gas turbine engines require protection from fuel gas liquid drop-out caused by the Joule-Thomson effect when natural gas is let down from transportation line pressure to the burner supply pressure. Indeed, gas turbine manufacturers specify a minimum gas superheat, which requires fuel gas heating at pipeline temperatures experienced ...

Pyrolysis and combustion kinetics and emissions of waste lube oils

Journal of Analytical and Applied Pyrolysis, 2003
Abstract The present work studies first the kinetics of the global primary thermal decomposition of raw waste lubricant oils in helium atmosphere conditions and with different proportions of helium:oxygen by TGA. In addition, pyrolysis and partial oxidation runs were carried out in a tubular reactor at 723 and 1123 K, where the volatiles and ...

Investigation of Thermodynamic Parameters in the Thermal Decomposition of Plastic Waste−Waste Lube Oil Compounds

Environmental Science & Technology, 2010
Thermal decomposition properties of plastic waste-waste lube oil compounds were investigated under nonisothermal conditions. Polyethylene (PE), polypropylene (PP), polystyrene (PS), and polyethylene terephthalate (PET) were selected as representative household plastic wastes. A plastic waste mixture (PWM) and waste lube oil (WLO) were mixed with mixing

Modification of waste tire pyrolytic oil as base fluid for synthetic lube oil blending and production: waste tire utilization approach

Journal of Material Cycles and Waste Management, 2020
This study provides an environmentally friendly process for the production of waste tire pyrolytic oil from fast pyrolysis for use in lube oil production. The produced waste tire pyrolytic oil was further distilled to provide an almost pure base fluid for production of lube oil. The distilled pyrolytic oil was further transformed to lube oil via polyol

Recycling Waste Lube Oils for Profit (UOP Direct Contact Hydrogenation Process)

Hazardous Waste and Hazardous Materials, 1989
ABSTRACT An innovative new re-refining process has evolved from existing commercial petroleum refinery technology providing an economic means of treating and recycling potentially hazardous waste oils. Direct Contact Hydrogenation (DCH) eliminates the need for burdensome pretreatment steps such as dewatering, light ends removal and vacuum evaporation ...

Desulfurization of pyrolysis fuels obtained from waste: Lube oils, tires and plastics

Fuel, 2015
Abstract An interesting source of hydrocarbon fuels that has attracted considerable attention in the last few years is the pyrolysis of waste materials of organic origin, like tires, lube oils and plastics. However, one main drawback, among others, of these pyrolysis fuels is their high sulphur content that makes them inappropriate as automotive or ...

Efficiency and energetic analysis of the production of gaseous green fuels from the compressed steam and supercritical water gasification of waste lube oils

The Journal of Supercritical Fluids, 2021
Abstract The gasification of a waste lube oil (WLO), using water under vapor and supercritical states leads to its valorization into green fuels with high energetic power like H2 and CH4. This work investigates how the most important variables of a flow continuous gasification process, temperature, pressure and reaction time, influence the efficiency
