ASPHALTENE DISPERSANT PDF

ICL Innovation, a technology incubator for the ICL group, seeks novel asphaltene inhibitors and asphaltene dispersants for the oil industry. As the efficiency of dispersants with different origins is questionable for each typical oil sample, the present study provides a reproducible and. Dodecyl resorcinol has the best performance at concentration of 50 ppm as an asphaltene dispersant and causes required n-heptane volume increment of 2%.

Asphaltene Dispersant & Pour Point Depressant

Therefore, it is very important to use asphalgene actual oil during production selection. Criteria for dispersant application and selection are discussed, which include the application of a novel laboratory technique to assess asphaltene stabilization in the crude oil.

Proceedings of an International Asphalrene Submersible Technology: Did you find what you were looking for? AI agents are polymeric resinous materials that stabilize the asphaltenes and prevent destabilization, agglomeration and flocculation of asphaltenes by forming strong association with asphaltene moieties. As a technology incubator, ICL Innovation is looking only for innovative technologies that may be further developed and commercialized through a business unit in ICL.

However, some asphaltene inhibitors do now show a critical concentration, but instead show an accumulative effect in reducing the amount of asphaltene precipitation. These are asphaltene dispersants AD and asphaltene inhibitors AI. This is partially contributed to the presence of organic acids in the oil. Since asphaltene inhibitors prevent precipitation, they are best applied upstream of the location where asphaltene onset pressure occurs, typically downhole.

They have been successfully applied for inhibition and removal of asphaltene deposits in production equipment. In general asphaltene inhibitors are polymeric chemistries with charged groups that are aimed to function as artificial resins to keep the asphaltenes in solution.

Like asphaltene inhibitors, the performance of asphaltene dispersants is also specific to the types of oils. Petroleum disperxant are defined as a solubility class of the heavy components in crude oil which are insoluble in nonpolar solvents. Asphaltene deposition is a major problem both upstream and downstream in the petroleum industry. Once agglomeration occurs, destabilized asphaltenes can form a thick pad in the dehydration equipment, which significantly reduces the demulsification rate.

Publishers Content Coverage Privacy. One major problem is their agglomeration at the water-oil interface of crude oil emulsions.

The absorption interaction between an asphaltene and an amphiphile molecule natural resin or synthetic additive is considered the most important parameter for the stabilization of asphaltene micelles in crude oil. They typically do not show a critical concentration effect and the effectiveness is proportional to the concentration.

Two case studies are presented that demonstrate how asphaltene dispersants can efficiently inhibit pad formation and help reduce demulsifier dosage. AI additives prevent the aggregation of asphaltene molecules, whereas AD additives are usually non-polymeric surfactants.

Some asphaltene inhibitors demonstrate a critical concentration level below which no performance is observed, but once above, it shows a dramatic effect by preventing asphaltene from flocculation.
