non-combustion applications

Commercially Proven Clean Innovation

Well Resources' commitment to petroleum sector innovation has led to significant discoveries that change the landscape of the petroleum value chain. These recent discoveries allow for the utilization of petroleum asphaltenes for non-combustion applications, which have major cross-sector opportunities in addressing environmental issues such as water and soil contamination.

The breakthroughs are based on understanding the properties of solid, dry, granular asphaltenes, which are uniquely produced from Well Resources' commercial SELEX-Asp process. Granular asphaltenes are easy to handle and transport, are an effective adsorption material and method for treating pollutants, and can also be used as feedstock for producing various carbon materials.

Effective Resource Utilization

Traditional low-value petroleum residue by-products are turned into environmentally friendly and high value-added materials, which can dually serve as carbon capture mediums for the energy sector. This works towards the goal of net-zero emissions and sustainable development for the water-energy-food nexus.

Water Treatment & Soil Remediation

The use of asphaltenes in the treatment or mitigation of environmental damage caused by contaminants in water and soil is more cost-effective and efficient than traditional methods.

Traditional Methods

Existing strategies used to address water contaminants (such as sewage, chemicals, and dissolved organic substances) are either costly to implement or have drawbacks that result in further environmental damage. Traditional soil remediation strategies used to treat residual farm chemicals (such as herbicides, pesticides, and fertilizers) are costly and energy intensive to implement; consequently, most contaminated agricultural lands remain untreated.

Asphaltene Processing

Asphaltenes can be used as feedstock for producing various carbon materials, such as fibers, mats, and fillers. The applications for processed asphaltenes can vary from packing materials, to construction materials, to containing-materials that doubly exhibit decontamination effects.

About Petroleum Asphaltenes

Asphaltenes are naturally occurring, non-soluble hydrocarbons comprised of 85-87% carbon, and are found in increasing amounts in heavy and ultra-heavy crudes. It is not economically viable to convert asphaltenes into clean transportation fuels.

Hydrogen addition and carbon rejection are the common methodologies used by refiners to manage asphaltenes. Hydrogen addition technologies transform a fraction of asphaltenes into smaller and more manageable molecules, but such processes are expensive and highly energy intensive. Carbon rejection entails removal of heavy petroleum sub-fractions, and can include asphaltene removal by thermal separation into petroleum coke.


Petroleum coke may be used as a solid fuel substitute for power generation; some are stockpiled or disposed of at a cost to a refiner. Conventional solvent-based or slurry phase separation processes produce asphaltene-rich semi-liquid or pitch by-products that require secondary treatment or specialized disposal.
