PRODUCT RANGE
The Basorol ® types are concentrated single products designed for u as components for demulsifier formulations. In order to optimize
performance, it may be necessary to blend two or more Basorol ® types. Basorol ® types are classified into 5 groups:
GROUP 1 T he alkoxylated butyl, amyl and nonyl phenol resins have the broadest
treating range for crudes. Normally they are the predominant part of the formulation and they allow emulsions to be treated at lower temperatures.
GROUP 2 T he are EO / P O block-co-polymers which are ud to treat high-gravity
crudes, enhance the interface, clean up and improve water clarity. They are often blended with Basorol ® Group 1 products to improve the interface and /or water clarity. High RSN value products wet solids and iron sulfides.
GROUP 3 T hey act as polishers, brighteners and finishing compounds. They can increa the speed of water drop similar to the alkoxylated poly e thyleneimines (Group 5). Combination with phenolic resins (Group 1) is recommended to treat low- to medium-gravity crudes.
GROUP 4 C onsists of amine alkoxylates which help to reduce residual water and
salt content. They can be blended with Basorol ® Group 1 products to improve the interface and /or water clarity. High RSN value products wet solids and iron sulfides.
GROUP 5 T he alkoxylated polyethyleneimines (PEI) are often ud in combination
with Basorol ® Group 1, especially in low- to medium-gravity crudes. They often lead to improved water clarity.

The most important objective of any oil production facility is the paration of water from produced crude. The quick and efficient breaking of the emulsions is esntial to meet tight downstream crude oil specifications. In general crude oil is produced as a water-in-oil emulsion and demulsifiers are necessary for breaking such emulsions. The factors involved in treating emulsions include breaking the film surrounding the small water droplets and coalescing the droplets to produce larger drops. Finally the water drops ttle during or after their coalescence.
INITIAL RECOMMENDATION
FOR BOTTLE-TESTING
1. S creen Group 1 and Group 5 as single components.
2. C ombine the best out of each class (usually 1:1,
远走高飞原唱歌曲1:2, 2:1 ratios).
3. T o achieve the desired performance you can also
screen for the blockcopolymers (Group 2 + 4) and
polyol alkoxylates (Group 3).
4. T he u of DDBSA (dodecylbenzylsulfonic acid)
can improve formulation performance if added
in small amounts (1– 2 %).
Remarks
• D ilute all products to be screened to 5 – 10 % in an aromatic
solvent (add isopropanol if necessary for solubilization) before
addition to the crude oil emulsion.
• S hake vigorously after addition to ensure complete mixing of
the demulsifier.
• D o not add more than approx. 300 uL of the diluted demulsifier
to avoid solvent effects.
FUNCTION GUIDE
The ba components of a demulsifier can generally be
characterized by their function in breaking up emulsions.
In addition it is also noted that veral demulsifier bas
can be multipurpo in their function depending on the
nature of the emulsion.

droplets and relea free water. The most common types are
bad on alkoxylated resins.
TREATERS T he function of the components is to help flocculate
sub-micron water particulates that are disperd in the crude.
They are also referred to as drying agents. Alkoxylated
polyethyleneimines (PEI) are one of the most successful

DESALTERS E mulsions in a desalter unit usually contain low amounts of
长津湖的观后感water and are less stable due to the removal of emulsifing
agents in previous demulsification stages. In addition, a
high potential electric field is applied to help coalesce the

polar salt water droplets. A desalter demulsifier ba will
exhibit rapid water paration and be able to handle
crudes from various origins.
W ETTING AGENTS T he components’ primary function is to interact with solids,
e. g. sands or iron sulfides, contained in the crude. High RSN
value products rve to change the wettability of their surfaces.
