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 Dispersants for Oil Industry | ICL Innovation

Asphaltene deposition is a major problem both upstream and downstream in the petroleum industry. Proceedings of an international conference Oceanology: Peer reviewed only Published between: Publishers Content Coverage Privacy. Advanced search Show search help. Our research and development laboratories in North America, South America, Europe, Asia and Australia are staffed with industry experts and state of the art analytical and application equipment.

During transport in pipes, following oil processing, asphaltene builds up on pipes and other equipment. Asphaltene inhibitor AI refers to chemical additives that help prevent asphaltene deposition when dosed at very low concentrations into the oil up to a few hundred parts per million by volumeunlike asphaltene solvents that typically require much higher concentrations to work percent level.

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. It is usually injected on an continuous basis through a downhole aspha,tene string.

Destabilization of petroleum asphaltenes may cause a multitude of problems in crude oil recovery and production. They provide real inhibition since they prevent the aggregation of asphaltene molecules and therefore shift the asphaltene onset pressure. Although generally referred to as asphaltene inhibitors by the industrythis class of additives can actually further divided as asphaltene inhibitors and asphaltene dispersants, depending on their mechanisms of preventing asphaltene deposition.

Certain polymeric dispersants increase asphaltene solubilization in hydrocarbon media, and when used in conjunction with emulsion breakers, facilitate the demulsification process. Food Agro Engineered Materials Biofilm dispersang and removal from water based systems Molten salt heat transfer fluid New uses for Bromine ATO alternative as flame retardant synergist Multi-functional brominated biocides Non halogenated flame retardants Dirt Pick Up Resistance DPUR for roof coatings Penetrating aid for asphalt cement Magnesium hydride for hydrogen storage New industrial uses for polyhalite Encapsulation of low mp salts Sulfur-less polymer cross linking agent for asphalt Asphaltene Dispersants diapersant Oil Industry.

These naturally occurring dispersions can be easily disturbed by a variety of mechanical and physicochemical conditions involved in oil field recovery and production, Changes dispsrsant temperature and pressure, commingling of crude and condensate streams, and especially the use of enhanced recovery techniques can result in asphaltene destabilization, precipitation, and eventual deposition.

Petroleum asphaltenes are defined as a solubility class of the heavy components in crude oil which are insoluble in nonpolar solvents. Two case studies are presented that demonstrate how asphaltene dispersants can efficiently inhibit pad formation and help reduce demulsifier dosage.

Proceedings of an international conference Diverless and Deepwater Techology: The technique monitors asphaltene agglomeration while undergoing titration with an incompatible solvent precipitant. Society of Petroleum Engineers Disciplines 4. These are asphaltene dispersants AD and asphaltene inhibitors AI. One major problem is their agglomeration at the water-oil interface of crude oil emulsions. Criteria for dispersant application and selection are discussed, which include the application of a novel laboratory technique to assess asphaltene stabilization in ssphaltene crude oil.

In general asphaltene inhibitors are polymeric chemistries with charged groups that are aimed to function as artificial resins to keep the asphaltenes in solution.

If not chosen properly, some asphaltene inhibitors can actually make the asphaltene problem worse by precipitating more asphaltenes compared to an untreated system [ 3 ] [ 4 ]. Marques, Gaspar Gonzalez, Jair B. It has been reported that asphaltene inhibitor performance from lab testing does not necessarily reflect the performance in the field [ 1 ].

Tell us about your innovation. If an asphaltene inhibitor contains long alkyl long chains, it can help disperse any formed asphaltene aggregates as well. Del Bianco and F. The proposal would need to clearly describe the technical concept chemical approach, structure if IP protected and proof of concept results, if available.

By posting, you agree to be identified by your IP address. 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. Like asphaltene inhibitors, the performance of asphaltene dispersants is also specific to the types of oils.

Information on ICL’s current product line can be found at www. For example, continuous or batch downhole treatments prevented deposition in the flowlines and tubing providing increased production rates and decreased downtime for many producers. AI additives prevent the aggregation of asphaltene molecules, whereas AD additives are usually non-polymeric surfactants.

Once deposited, asphaltenes pose a multitude of problems for crude oil producers. Most common ones are xylene and toluene. Proceedings of an International Conference Submersible Technology: It is well-known that the performance of asphaltene inhibitors are oil-specific. As mentioned previously, the asphaltene performance is very oil-specific. Gonzalez, “Stabilization of asphaltenes by phenolic compounds extracted from cashew-nut shell liquid,” Journal of Applied Polymer Science, 73 1 Sheriff’s Encyclopedic Dictionary of Applied Geophysics, fourth edition.

There are two types classes of additives used to tackle the asphaltene problem at the production sites. 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. A product that works well on one type of oil may not work well on other fluids.
