Breakthrough Crystalline Membranes Transform Oil Processing
July 11, 3:00 PM
A global team of scientists has published a study in the journal Science detailing a novel approach to oil refining using crystalline membranes. This cutting-edge technology separates crude oil without the need for heating, dramatically cutting the energy required for the process.
Tests conducted on undiluted Arabian Light crude oil yielded impressive results:
- A two-stage system boosted the concentration of aliphatic compounds from 54.5% to 96.1%;
- Energy consumption during processing was just 20.7 megajoules per barrel—half the typical range of 50 to 200 megajoules per barrel.
Traditional crude oil distillation consumes roughly 11% of all energy derived from the extracted resource. The new method relies on membranes built from covalent organic frameworks (COFs), which feature tunable pore sizes and subnanometer channels. This design enables the system to effectively trap most benzenes and naphthalenes during filtration.
What This Means for the Industry
The researchers have also established a continuous roll-to-roll production process for membrane sheets measuring 50 meters in length and 0.3 meters in width. Rolled membrane modules proved durable, operating for over 250 hours in a pilot system, with permeability fully restored after routine cleaning.
These advances open up new opportunities to lower oil refining costs and reduce energy expenditures, which could have a major impact on the sector as a whole. Cheaper refining would mark an important step toward more efficient use of energy resources.
This new technology could become a key tool in addressing the energy crisis, as reducing power consumption during oil processing not only cuts costs but also benefits the environment. Since conventional refining methods are highly energy-intensive, adopting membrane-based solutions may help lower carbon emissions and promote sustainability within the oil and gas industry.
