Some Vegetable Oil‐Based Additives for Petroleum Industry: A Review of Sunflower, Rapeseed and Used Cooking Oil‐Derived Surfactants

Engineering Reports, Volume 7, Issue 9, September 2025.
Green additives in the petroleum industry: Vegetable oil‐based surfactants and EP additives offer a sustainable alternative for the petroleum industry. ABSTRACT The increasing environmental concerns associated with conventional petroleum‐based additives—such as high toxicity, poor biodegradability, and long‐term ecological persistence—have driven the ...

Organic alkalis as potential additives in hot water flooding for enhancing heavy oil recovery

The Canadian Journal of Chemical Engineering, Volume 103, Issue 8, Page 3955-3970, August 2025.
Abstract Alkali–surfactant–polymer (ASP) flooding is a chemical enhanced oil recovery method; its working mechanisms include mobility control, wettability alteration, and in‐situ emulsification. However, conventional alkalis used in the ASP flooding could cause some serious issues, including scaling, formation damage, and pipe corrosion. In this study,

The Fusion of Elemental Sulfur With Waste Cooking Oil‐Based Derivatives: Beyond Renewability

European Journal of Lipid Science and Technology, Volume 127, Issue 7, July 2025.
The fuse of two waste streams, elemental sulfur and waste cooking oil, is enabled by Inverse Vulcanization. The process might ensure the closed‐loop production of polymeric materials for a wide range of applications, beyond its sole potential renewability.

Evaluation of surface, foam, emulsion, and clouding properties of a family of nonionic surfactants from oleic acid derivatives

Journal of Surfactants and Detergents, Volume 28, Issue 4, Page 871-881, July 2025.
Abstract This study investigated the properties, namely: surface tension, foam, emulsion, and cloud point of a library of bio‐based surfactants (represented as CnEOm where C is hydrophobic carbon chain and EO is ethylene oxide). The surfactants were derived from ring‐opening alkyl oleate epoxides with polyethylene glycol (PEG) and monomethyl ...

Evaluating Properties and Applications of Innovative Recycled Aggregate Concrete

Engineering Reports, Volume 7, Issue 6, June 2025.
Methodology flowchart. ABSTRACT The global demand for concrete, driven by rapid industrialization and urbanization, has led to significant depletion of natural aggregates and increased environmental concerns. Natural aggregates, which constitute about 70%–80% of concrete mix volume, are essential for concrete production, but their extraction ...

A review on application of waste cooking oil as rejuvenator in porous asphalt mixture [PDF]

, 2016
Aging process of bitumen is one of the main obstacles, which limit the implementation of porous pavement. An aging process would cause a shorter service life of porous asphalt compared to the conventional hot mix asphalt mixture.

Chemical enhanced oil recovery from shale‐rich tight carbonate reservoirs using 2‐butoxyethanol as a mutual solvent and diluted seawater

The Canadian Journal of Chemical Engineering, Volume 103, Issue 5, Page 2119-2135, May 2025.
This graphical abstract shows the experiments conducted, including interfacial tension, contact angle, oil swelling and production under imbibition, along with graphs presenting the results. Abstract Oil production from tight reservoirs due to their very low permeability and high capillary pressure requires complex operations and materials, so that ...

Overview on cold cement bitumen emulsion asphalt

RILEM Technical Letters, 2016
Cold mix asphalt, a promising substitute for conventional hot mix asphalt, is manufactured at ambient temperature using bitumen emulsion as binder. To improve its strength and durability, cement is often added to the mixture. This review (1) presents an overview about advances in cold mix asphalt modified with cementitious materials, often called CBEA (
