High capacity pastillation of low viscosity slurry
products
IPCO expands Rotoform range with high
yield, low maintenance XG model for
granulation of suspensions
C
hemical processing systems manufacturer IPCO has announced
the introduction of the Rotoform XG, a high capacity
pastillation system offering superior handling of low viscosity
melts containing solid particles, and significantly easier cleaning
and maintenance.
Designed for applications such as sulphur bentonite, NPK and
other fertilizers as well as urea mixes, the new model can convert
solid-containing melts into high quality pastilles from 2-4 mm diameter.
The XG is also able to process catalysts, wax suspensions
and other products containing solid additives or contaminant particles
up to 200 μm in size.
Offering twice the throughput rates of the standard Rotoform
4G model, the XG is capable of processing slurries with viscosities
lower than 100 mPas.
The design follows the same basic principle that has seen
more than 2500 Rotoform installations completed since the process
was introduced in the late 1970s. Liquid product is delivered
to a stator then deposited in drop form via a rotating perforated
outer shell onto a continuously running steel cooling belt.
However, the XG incorporates a number of productivity-enhancing
innovations including a sliding base frame that allows
the Rotoform to be pulled out for easy access, and a completely
new stator design that makes cleaning and maintenance much
easier. A new bearing system with fewer parts and increased wear
resistance further reduces maintenance requirements.
" This is a major development in terms of handling slurry
and abrasive products, " explains Ulrich Nanz, Global Product
Manager, Chemicals, at IPCO. " The high capacity of the system
maximises productivity, while easier cleaning and maintenance
equates to lower costs. "
The speed of the Rotoform is synchronised with that of the belt
ensuring gentle deposition of the droplets. Heat released during
solidification is transferred via the steel belt to cooling water
sprayed underneath, so there is no risk of cross-contamination
and the water can be cooled and re-used.

High-pressure Venturi scrubbers for clean hydrogen
Cooling - scrubbing - dedusting - humidifying - mixing
A
longside Venturi scrubbers' conventional usages, there's rising
demand (especially by some high-pressure processes) for
them to perform and make improvements to cleaning, dedusting,
humidifying, and mixing tasks. Examples can be found in syngas
treatment and production, coal gasification and conversion to industrial
alcohol/ether.
Syngas production, i.e. the industrial production of gas mixtures
and H2, are just examples of the wide range of potential
applications. The composition of the primary gases varies depending
on the application, but mostly consists of H2, CO, CO2,
N2, and H2O which virtually always contain a certain amount of
process-related soot. Water is used as the scrubbing medium.
Körting high-pressure Venturi scrubbers are used in numerous
processes e.g. Steam methane reforming (SMR), Multi-purpose
gasification (MPG®) and others.
Over 40 years of experience
The first projects with high-pressure Venturi scrubbers were
carried out back in 1978. Körting Hannover GmbH draws on decades
of experience with jet ejector technology and gas scrubbers
to design this sophisticated process-engineering equipment. To
come up with the best customised solutions, we collaborate with
our in-house development department to conduct CFD simulations
and trials on our own test rig.
To ensure long service lives and minimal maintenance, highpressure
Venturi scrubbers are often made of, or clad with special
54
materials or special material
combinations, such as
stainless steel or duplex
stainless steel and subjected
to stringent quality
assurance inspections.
Special technical features:
* Pressure: 1 - 80 bar
* Material: wall thicknesses
from 10 - 60 mm
* Flanges: 600 - 900 lbs.
* Temperatures: 200 - 400 °C
* Nominal widths: DN 200 - 1200
* Gas inlet: axial (alternatively lateral at 90°)
Due to high-precision manufacturing, predominantly at the
Hanover site in Germany, Körting ensures that high-pressure
Venturi scrubbers are designed and made based on the requirements
of the customer and processes, as well as the necessary
specifications and codes. The appropriate process-engineering
and mechanical design calculations are also carried out.
