FIBER FILM versus Conventiona l Technologies
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 numerousshortcomings 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.
-
8/11/2019 Merichem Process Technologies Brochure (English)
11/31
Dispersion Problem
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.

The FIBER FILM C ontac tor Basics
Intimate Contact Without Dispersion
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 pack-
ing 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 allow-
ing impurities to easily diffuse between phases.
Additionally, emulsions and aqueous carryover are negligible occur since
surfac e tension causes the a queous phase to a dhere 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.

The FIBER FILM C ontac tor
Effective treating results
Achieves maximum removal of
impurities from the hydrocarbon
to meet customers standa rds.
High mass transfer efficiency
The large interfac ial surface
area, the microscopic diffusion
distance, and the continuous
renewal of the aqueous phase
combine to yield mass transfer
efficiencies far greater than
possible with conventional
treatment.
Tec hnology Advantages
ULTRA-THIN FALLING FILMS
Elimination of carryover
Bec ause the a queous phase adheres to the fibers in the FIBER FILM C ontactor
rather than being dispersed into the hydrocarbon phase, c arryover is virtually
eliminated.
Elimination of emulsion formation
Since effective phase contact occurs without dispersion, stable emulsions will
not form in the FIBER FILM C ontactor unit.

The FIBER FILM C ontac tor
Tec hnology Advantages
Reduced equipment size and cost
Since the FIBER FILM Contactor system does not depend on gravity settling or
emulsion coalescenc e, processing vessels can be muc h 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.
Lower operating costs
High caustic strength and recycle capability reduces use of fresh caustic as
well as providing excellent turndown c apability.
TYPICAL SEPARATION TIMES

60-90 minutes

Simplified, easily operated equipment
By eliminating the clean-up stages,
FIBER FILM C ontactor systems are muc h
simpler to operate and maintain than
conventional treating equipment. In
addition, Merichems straightforward
designs make automation and control
easy.

REGENtechnology processes regenerable rich caustic streams produced in the refinery allowing it to
be rec ycled thereby significantly improving caustic utilization. Typica lly REGENis coupled with extrac-
tive 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
stringenc y of the trea ted product specifications, the REGENdesign will employ disulfide oil (DSO)
gravity separation and/or solvent washing step(s) to minimize the impact of DSO back-extraction. In
addition, REGENtechnology is equally effec tive at reviving rich/spent caustic streams emanating
from conventional refinery trea ting units.
REGENtechnology 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) c an be ac commo-
da ted in the rich caustic and many times negates the need for a H2S pre-wash stage in the hydroca r-
bon 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
