Caustic treating processes with dispersive mixing devices were once
the only option available to the industry. Yet conventional dispersion
and phase separation methods are subject to numerous
shortcomings – lack of turndown capability, pluggage, flooding,
channeling, unpredictable treating results, long settling times,
aqueous phase carryover, generation of dilute aqueous wastes,
lower service factor, hydrocarbon losses, larger plot space, product
contamination, and additional processing steps and equipment
needed to separate phases.
Dispersion Problem
Conventional Systems = Conventional Problems
•
Even when the dispersion-based system provides adequate
treatment, separating the two phases is usually extremely inefficient.
The mixture must remain in the phase separator until the caustic
droplets settle out by gravity, a process that may take hours. As the
treating requirement becomes more difficult, mixing energy is
increased to maximize interfacial surface area leading to a greater
dispersion of the aqueous phase causing the separation time to
become exponentially longer.
•
Stable emulsions can form in the mixing device resulting in massive
carryover out of the separator vessel. Due to excessive carryover,
expensive equipment such as knockout vessels, sand filters, and
water wash units must be installed downstream to remove the
dispersed aqueous phase from the treated product. Treatment is
often interrupted if an emulsion develops.
•
The conventional method of contacting two immiscible liquids – such
as hydrocarbon and caustic or amine – is to disperse one liquid
thoroughly into the other as small droplets. Impurities pass between
the two phases at the surface of the droplet. Mass transfer can only
be improved by creating more numerous and smaller droplets in
order to increase surface area.

Treating
Solution Out
In a FIBER FILM Contactor, the aqueous phase adheres to (wets) the metal
fibers and is continually renewed as it flows down the length of the fiber via a
combination of gravity and interfacial drag between the two immiscible
phases. Hydrocarbon also flows through the cylinder cocurrently and in
between the aqueous-wetted fibers. The large surface area and tight packing of the metal fibers bring ultra-thin falling films of the aqueous phase into
intimate contact with the hydrocarbon phase. The interfacial surface area
produced is orders of magnitude larger than in conventional devices allowing impurities to easily diffuse between phases.
Additionally, emulsions and aqueous carryover are negligible occur since
surface tension causes the aqueous phase to adhere to the metal fibers while
the hydrocarbon phase flows freely between the wetted fibers. The result is a
highly efficient mass transfer of impurities from one phase to the other with
little to no emulsification, carryover, or high pressure drop.

than

Elimination of carryover
Because the aqueous phase adheres to the fibers in the FIBER FILM Contactor
rather than being dispersed into the hydrocarbon phase, carryover is virtually
eliminated.
Elimination of emulsion formation
Since effective phase contact occurs without dispersion, stable emulsions will
not form in the FIBER FILM Contactor unit.
The FIBER FILM® Contactor
Technology Advantages
Reduced equipment size and cost
Since the FIBER FILM Contactor system does not depend on gravity settling or
emulsion coalescence, processing vessels can be much smaller. In most cases,
expensive downstream coalescers and other cleanup equipment are not
required. With fewer pieces of smaller equipment, plant space is more
efficiently utilized.
Simplified, easily operated equipment
TYPICAL SEPARATION TIMES
By eliminating the clean-up stages,
60-90 minutes
FIBER FILM Contactor systems are much
simpler to operate and maintain than

addition, Merichem’s straightforward

Fiber-Film® Contactor
Lower operating costs
High caustic strength and recycle capability reduces use of fresh caustic as
well as providing excellent turndown capability.
The FIBER FILM® Contactor
Flexible and Adaptable System Design
Adaptable to Client needs

MERICON™ technology was first licensed in 1988 and to date Merichem has
granted 27 unit operating licenses world-wide. The design of the system is
based on more than 75 years of first-hand operating knowledge gained from

REGEN® technology processes regenerable rich caustic streams produced in the refinery allowing it to
be recycled thereby significantly improving caustic utilization. Typically REGEN® is coupled with extractive THIOLEX™ technology to regenerate the mercaptide-rich caustic purged from the THIOLEX™
system and returns a lean caustic stream for additional mercaptan removal. Depending on the
stringency of the treated product specifications, the REGEN® design will employ disulfide oil (DSO)
gravity separation and/or solvent washing step(s) to minimize the impact of DSO back-extraction. In
addition, REGEN® technology is equally effective at reviving rich/spent caustic streams emanating
from conventional refinery treating units.
REGEN® technology was first licensed in 1980 and to date Merichem has granted 151 unit operating
licenses world-wide. Moderate levels of sodium sulfide (salt of hydrogen sulfide/H2S) can be accommodated in the rich caustic and many times negates the need for a H2S pre-wash stage in the hydrocarbon extraction section of the treating unit resulting in less capital expenditure.
The design of the system is based on more than 75 years of first-hand operating knowledge gained from
Merichem-owned plants. This factor, when coupled with Merichem’s extensive licensing experience,
makes REGEN® the technology-of-choice.
