A novel water-soluble viscosity reducer system based on polycyclic aromatic hydrocarbon
(PAH) was designed and synthesized for heavy oil viscosity reduction and enhanced heavy …

High polar asphaltenes are easy to precipitate and deposit in transportation pipelines and
subsequent processing. Adding chemical polymer inhibitors is an effective method to inhibit …

The deposition of asphaltenes in the petroleum industry has been found to be a significant
factor affecting the profitability of petroleum production and refining. For this reason, many …

Molecular dynamics simulations have been employed to investigate the effect of molecular
polydispersity on the aggregation of asphaltene. To make the large combinatorial space of …

A high content of asphaltene and wax in crude oil leads to difficulties in the recovery and
transportation of crude oil due to the precipitation of asphaltenes and the deposition of …

The high viscosity characteristics of heavy oil make it difficult to extract, transport and
process. Therefore, enhancing the fluidity of heavy oil can effectively improve the economic …

The purpose of this work was to investigate the effects of polystyrene-based acidic
copolymers and ionomers on the dispersion of asphaltenes in heavy oil. In the first part of …

Since the implementation of the sulfur cap legislation in 2020, marine very-low-sulfur fuel oil,
often known as VLSFO, has become a crucial source of fuel for the contemporary shipping …

The precipitation and deposition of waxes in high waxy crude oil often result in the low
throughput and clogging of pipeline. Adding polymers is a practical approach to solve these …

As the largest component in crude oil, asphaltenes are apt to settle out and result in the
blockage of pipeline during production and transportation, which largely reduces the safety …
