Paraffin Control Solution
___________
Ensure Extended Production with
Proven Paraffin Mitigation Solutions
Crude oils naturally contain saturated hydrocarbon fractions also called wax or paraffin can cause flow challenges when deposited on oil pipeline walls during the production, transportation and storage of oil and gas. During production, the crude cools down as it flows from the hot reservoir to the cooler surface. During this cooling process, wax crystallization can occur resulting in wax deposition and/or a subsequent increase in viscosity, making it more difficult, if not impossible for the oil to flow uniformly though the pipeline.
From proactive, preventive applications, to remedial steps designed to restore operations to their optimal levels if and when wax buildup does occur, our innovative chemistries and technologies help improve flow and bring more oil to the surface. Our solutions address both organic and inorganic flow assurance challenges, effectively combating paraffin deposits regardless of temperature shifts, climatic conditions or the cooling rates of tanks and pipelines.
DOSAS’ innovative and customizable Paraffin control solution and technologies are available in multiple formulations that provide superior control for wax buildup.
DOSAS has designed a wide range of high-performance products, EmendaFlow™, which help you to mitigate paraffin deposits and can significantly lower the pour point of your paraffinic crude. Several EmendaFlow™ products may display multiple functions depending on the nature of the crude oil.
Pour point Depressant
Additives that reduce the pour point of crude oils are known as pour point depressants (PPDs) or flow improvers. Upon cooling, wax separates as plate-like crystals or needles. These crystals interact to form a three-dimensional network in which the crude oil is trapped, resulting in increased viscosity or even solidification of the bulk oil phase. PPDs affect the crystallization process and prevent the formation of such three-dimensional networks, thereby reducing the pour point.
Crystal Modifier
Chemicals that affect the amount of wax that is deposited in e.g. cold-finger tests or in a coaxial-shear cell test are usually referred to as wax inhibitors. In some cases, the wax appearance temperature (WAT) or the cloud point is also affected. Wax inhibitors generally influence the crystal morphology, creating weaker deposits that are more easily removed by shear forces within the flowing crude.

| EmendaFlow™ 300 Paraffin Inhibitor | Is used to disrupt the wax crystallization process that could interfere with production, therefore lowering the cloud point. |
Dispersant
Wax dispersants can reduce the amount of wax deposits in flowlines by different mechanisms depending on their chemical nature. Some will adsorb to pipeline surfaces thereby changing the wettability to water-wet. Others will adsorb to growing wax crystal surfaces reducing the tendency of the crystals to agglomerate.

Optimal Paraffin Treatment
Paraffin deposition can lead to equipment failure, production decline, expensive remediations, well shut-in, and storage tank plugging. Our proven approach starts with the gathering and examination of field information and the subsequent design and implementation of laboratory tests to determine the optimal treatment.
