![]() ![]() Introduction The most important objective of any oil production facility is the separation of water from produced crude. Keywords: Crude Oil, Emulsion, Demulsifier, Design of Experiments, Niger Delta 1. Thus, the combined demulsifier at 0.45mL concentration at a temperature of 90 C for 60 minutes gave a good potential that would necessitate its use for crude oil emulsion treatment in the Niger Delta. Again, the magnitude of the main and interaction effects of the combined demulsifier s factors on the separated water volume is affected by the selected demulsifiers combination ratio. Furthermore, the results depict that the selected (non-combined) demulsifiers and the combined demulsifier factors main effects on the separated water volume are concentration, while concentration-time and temperature-time are the factors interaction effects for selected and combined demulsifiers, respectively. Also, the performance of the combined demulsifier is dependent on the combination ratio of the selected demulsifiers. The results obtained shows that the selected demulsifiers DMO87005 and AnticorQIT007 in a combined form separate more water volume from the crude oil emulsion. Hence, the decision to use these demulsifiers to assess their combined potential and the demulsifier factors, namely, concentration, temperature and time effects on the separated water volume using design of experiments (DOE) approach. To achieve this objective, twelve different industrial-based demulsifiers were considered which were EXP50, Separol NF-36, Baker-Basf V13-312, Servo CC-8271, Tretolite RP6275, NACCO-Exxon, DMO87005, EXP30, AnticorQIT007, AnticorBE027, DMO86634 and DMO It was observed that DMO87005 and AnticorQIT007 produced better results based on separated water volume than other demulsifiers. In this study, crude samples were collected from the inlet manifold of a Niger Delta field and bottle tests were conducted with several demulsifiers to select the best chemical demulsifier for use in treating the emulsions as well as the optimum combination. No single universal demulsifier can effectively remove emulsion and a combination of two or more is usually expensive. There is a wide array of demulsifiers that are available in the oil and gas industry for the treatment of crude oil emulsion, but one major concern has always been the efficiency of the treatment. As crude oil is brought to the surface and pumped to the production facilities, the formation of emulsion increases operating cost. Treatment of crude oil emulsion is challenging when the emulsion is stabilized. 5, 2020, pp doi: /j.eas Received: SeptemAccepted: SeptemPublished: SeptemAbstract: Crude oil emulsion is an inevitable phenomenon in hydrocarbon production.

The substance providing its surface for the adsorption phenomenon is called adsorbent.Īdsorbent can be solid or liquid but not gas.Įxample: Important absorbents are activated charcoal, silica gel, alumina gel, clay, and colloidal particles.ĭuring adsorption, there is a decrease in the forces on the surface. ![]() Īdsorbate can be solid or liquid, or gas. The substance getting adsorbed on the surface of other substances is called adsorbate. The surface molecules show a greater tendency to attract the molecules of other substances, allowing them to settle on their surface and overcome unbalanced forces. The phenomenon of attracting and subsequently accumulating the molecules of a substance by a liquid or solid on its surface is called Adsorption. The molecules present on the surface of a substance are of greater energy than the molecules present in the bulk of the substance. Water molecules are absorbed into anhydrous calcium chloride. The phenomenon by which the molecules of a substance are attracted and uniformly distributed into the bulk of another solid or liquid substance is called absorption.Įxample: Ink gets absorbed into the bulk of a piece of chalk. Surface is an outermost or uppermost layer of a physical object or space.
