Kulim Kht Interfacial Tension in Enhanced Oil Recovery

Enhanced Water-Oil Separation 

nhanced Water-Oil Separation 

Scenario: In an offshore oil production platform, the production stream includes a significant amount of water, which forms an emulsion with the crude oil due to high surface tension. Application: By lowering surface tension using appropriate surfactants, contact angle and surface energy measurements can guide the selection of the most effective chemicals. This optimization improves emulsion destabilization, allowing for more efficient water-oil separation and reduced energy consumption during processing. 

Kulim Kht CO2 in Enhanced Oil Recovery

Enhanced Oil Recovery 

Introduction

Oil reservoirs are high temperature and pressure environments
that consist of porous rocks, oil, and various gases. Typically, after
the primary and secondary oil recovery processes, at least 50% of
the original oil still remains in the reservoir [1]. As the exploration
of new oil reservoirs is decreasing because of environmental
factors, there is a growing need to process the existing oil
reservoirs more efficiently.
One method for recovering additional oil, termed tertiary or
enhanced oil recovery, involves injecting carbon dioxide (CO2) into
the reservoir, to displace and dissolve more of the remaining oil.
This process can lead to an additional 8-16% recovery after the
primary and secondary recovery steps [1]. The interfacial tension
between hydrocarbons, water, and CO2 play an important role in
determining the effectiveness of the CO2-enhanced oil recovery

 Definition

Certain molecules can be classified according to their affinity towards polar and non-polar solutes. An affinity towards polar substances such as water is said to be hydrophilic, conversely an affinity towards non-polar substances such as hydrocarbons is said to be hydrophobic. A molecule may be either completely hydrophobic or hydrophilic, or it could have portions that are hydrophilic and portions that are hydrophobic. Such a molecule is said to be amphiphilic.

Amphiphilic molecules are very interesting, especially in the way they interact with water. The behavior can be considered to be similar to that of a magnet- the two ends of the molecule have opposite polarity and the water has the same polarity as one of the ends. The end with the same polarity as water is repelled away from the water (hydrophobic) and the end with the opposite polarity is attracted towards the water (hydrophilic). Two optional configurations exist, surfactants and micelles.  

This type of arrangement occurs at the boundary between any polar or non-polar liquid and air, if a non-polar liquid is used then the hydrophobic portion points downwards and the hydrophilic portion points upwards. The presence of these molecules at the surface disrupts the cohesive energy of the surface and thus lowers the surface tension. Such molecules are called surfactants, short for surface active molecules.

The other possible arrangement is with a cluster of molecules forming a ball within the liquid, known as a micelle. In the case of a polar liquid such as water the hydrophilic portions make up the exterior of the ball and the hydrophobic portions make up the interior.

In a non-polar liquid the arrangement would be such that the hydrophilic portions are pointed towards the center of the molecule and the hydrophobic portions are pointed away from the center. The formation of micelles is less favored than surfactants, which allows the investigation of amphiphiles through comparing surface tension with the concentration
