Raschig Jaeger Technologies – September 2006
In order to establish a new alliance in mass transfer business RASCHIG GmbH and its parent company
PMC GLOBAL INC have acquired JAEGER PRODUCTS INC., a Houston Texas based company, which is
a major manufacturer of tower packings, column internals and speciality trays and very active in the Mass
Transfer and Environmental Business.
RASCHIG JAEGER will be integrated into the PMC network of highly specialized, internationally operating
companies and will therefore be better prepared to meet increased globalization and further improved
customer orientation. Wherever in the world – in all continents – RASCHIG JAEGER is on the spot.
Synergies
This strategic acquisition combining RASCHIG and JAEGER into one larger group gives a great advantage
to our customers giving them access to products of both entities in Europe, The Americas and in other parts
of the world. It will create new dimensions in mass transfer technology. The advantages of our process
engineering know-how and our technologies benefit even more the planning, modernization and
construction of our clients’ processes. And: saving energy and investment cost is part of it.
The new alliance offers a diverse array of products to meet the mass transfer needs of the industries. While
specializing in high performance products, the comprehensive products line of RASCHIG JAEGER also
includes traditional fractional trays as well as structured and random packing types that best fit the
application.
Leading In-house distributor test-facility
The company operates one of the largest in-house distributor test-facilities worldwide. Liquid distributors
can be tested up to 12m in diameter at a maximum liquid load of 2400m3 per hour.
All products of RASCHIG JAEGER are the result of consistent development work long years of experience.
Comprehensive quality management in all stages of production and the principle of offering complete
solutions are the basis of our excellent reputation – worldwide.

Metal MAX-PAKTM
Test Results
MAX-PAKTM has been extensively tested at Fractionation Research, Inc. (FRI) and the Separations
Research Program (SRP) at the University of Texas. Test results indicate that MAX-PAKTM has superior
efficiency over similar structured packing
Benefits
Maximum mass and/or heat transfer efficiency due to high gas/liquid contacting.
• Increased throughput capacity and/or decreased pressure drop due to less resistance to fluid
• Good resistance to plugging and foaming conditions as well as process upsets resulting from special
shape and structure of the packing.
• Higher mechanical strength for the same thickness/gauge material due to the extension of tabs into the
grooved side of the corrugations.
• Ease of installation and maintenance.
•.Difficult separations involving large numbers of theoretical stages or transfer units achieved with lower
packing height as a result of maximum gas/liquid contacting.
• Low liquid rate distillation, absorption/stripping systems handled very efficiently due to effective liquid film
formation.
• Wide turn down characteristics due to nearly constant and low HETP achieved over wide operating
ranges
Features
MAX-PAKTM is comprised of a series of corrugated sheets having openings formed by strategically cutting
parallel slits in the shape of “W’s” and bending the material between the cuts in the opposite direction of the
corrugation. “V” shaped tabs , formed as a result of the slitting process, are precisely bent up and down to
increase open area and to direct liquid to the opposite side of the sheet. The openings and tabs enhance
gas and liquid turbulence further helping gas/liquid contacting.

INTRODUCTION
Jaeger Metal MAX-PAKTM is the most efficient and
economical structured packing in the industry today.
MAX-PAK structured packing is ideal for difficult
separations requiring a large number of theoretical
stages in low liquid rate absorption/stripping systems,
or applications that require a wide operating range
(turn down). This is due to very low pressure drop
across the bed and superior liquid spreading
characteristics over the packing surface.
TYPICAL APPLICATIONS INCLUDE THE
FOLLOWING FIELDS:
• Atmospheric crude oil and vacuum columns
FCC, coker and aromatic fractionators
• Various gasoline, naptha and light ends columns
• Ethyl benzene/styrene distillation for monomer
purification
• Ethylene oxide absorbers and isomer splitters
• Caustic/amine absorbers/strippers
Specially designed vertical sheets maximize
gas/liquid contacting, mixing and renewable liquid film
formation. These sheets incorporate pressure drop
reducing and liquid diversion openings that are
strategically located where they are needed resulting
in a higher volume throughput capacity with no dead
space. The shapes of the openings are specially
designed for guiding and directing gas and liquid
flows for full integration of gas/liquid contacting. The
unique design of these openings favors
communication between the back and front of each
layer, this providing maximum area and distribution.
In a typical application, the fluid flowing down the
column drips off the downward facing tabs and
spreads on the surface of the sheets. In high liquid
loading applications where the liquid might have a
tendency to bridge the opening, an upward bent tab
directs the liquid to the underside of the
corresponding sheet. This, MAX-PAKTM’s design
effectively handles a wide operating range.
• Glycol dehydrators and contactors
• Various heat sensitive purifications, such as
flavors/fragrances
• Vacuum distillations
• Steam Stripping
LIQUID & GAS DISTRIBUTION
Good initial distribution of vapor and liquid is essential
for the proper performance of any packing, and this is
especially true for high performance products like
MAX-PAKTM, VSP®, and Jaeger TRI-PACKS®. The
proper design and installation of gas and liquid
distributors has become a critical issue in mass
transfer applications projects. Jaeger has the
engineering and production capabilities to address
your distribution needs effectively to maximize the
performance of packings in your application. The
design of distributors goes hand-in-hand with the
selection of MAX-PAKTM. Jaeger can supply you with
a completely engineered package that includes the
packings, distributors, and other internals.

ENGINEERING SUPPORT
The success of a mass transfer job depends as much
on the quality of the hardware as it does on the quality
of the engineering support provided by the supplier.
Jaeger Products has acquired and continues to
develop the capability to provide its customers with
superior engineering support in the areas of packing
selection, tower and internals design, capacity and
efficiency improvement, and peripherals design. The
combination of packing and internals is individually
tailored for best results in each application.
Jaeger will assist you or your agent in the design and
installation of the total mass transfer system and will
always advise you when better choices of hardware
exist. Each mass transfer application is unique and
requires careful engineering to maximize design and
operation reliability. Call Jaeger Products with any
mass transfer question and you will have an interested
and sympathetic ear.
INTERNALS
Jaeger can also engineer and supply all other internals
associated with structured packing installations, such
as liquid collectors, redistributors, support plates, mist
eliminators, etc.
INSTALLATION
Layers of MAX-PAKTM elements are stacked one
above another by rotating them approximately 90
degrees. MAX-PAKTM’s standard design element is 12
inches tall and 12 inches wide which will pass through
and 18-inch access manway. Special size elements or
full diameter elements are also available and these
units can be supplied with lifting or pulling lugs. Heavy
gloves and protective clothing should always be worn
during handling and installation.
TEST RESULTS
All of the test data presented in this brochure is based
on independent work performed by the University of
Texas Center for Energy Studies, Separation Research
Program and Fractionation Research, Inc. Additional
tests are being performed by other universities and
independent testing organizations, and these results
will be made available when the work has been
completed

Cyclohexane-Heptane Distillation at Total Reflux
(SRP Tests In An 18” Diameter Column)
The above plot shows the effect of total pressure on HETP values. The low HETP of Max-PakTM makes it specially
suitable for vacuum distillation. The high capacity of Max-PakTM makes it a very important alternative in tower revamps as
well as in cost-effective grass root designs.
