Improving ejector bodies:
from porcelain to graphite.
GEA´s new development.Competitive
pricing plus no modifications needed.
EA Processes in the chemical industry are often high corrosive
and need strongly resistant materials. In the past only porcelain
was the material of choice but there was a considerably high risk
of damage. In cooperation with SGL, a major producer of carbonbased
products, GEA has developed a new ejector body made of
graphite to replace the former ceramic ejectors without any modifications
of the existing installations. Huge efforts have been made
on both sides in order to offer this new product to a very competitive
price. In fact, the former graphite ejector design was approximately
5-6 times more expensive than porcelain. Due to a very high
standardization, the price of the new graphite design is 2 to 2,5
times lower.
That makes GEA the most price-competitive graphite ejector
vendor on the market!
The advantages of the new system are:
* Very accurate dimensions vs porcelain
* Higher mechanical resistance
* Standard sizes for the body and customized sizes for internals
result in energy savings of more than 30 %
* Reduced manufacturing costs
* Reduce lead time (supplier keeps roughly machined objects on
stock, impregnated)

Large Pumping Speed
Range and ATEX-certified
Pfeiffer Vacuum has expanded its OktaLine
ATEX series of explosion-proof Roots
pumps
oots pumps from Pfeiffer Vacuum's
OktaLine are ideal for use in processes
in potentially explosive environments or for
evacuating explosive gases. Designed in accordance with the ATEX
Directive (2014/34/EU1 and/or 1999/92/EC) with pressure surge resistance
of PN 16, they meet the very highest explosion protection
requirements. Zone entrainment of explosive gases is ruled out as a
result. Potential applications range from the chemical, biotechnology
and pharmaceutical industries to industrial applications such
as vacuum furnaces or heat treatment.
As a result of the expansion of the series, pumping speeds range
R
from 280 to 8,100 m3/h. Depending on the application, there is a
choice between equipment category 2G or 3G. All pumps are suitable
for temperature class T3. Installation is possible without flame
arresters. This means that, effectively, the full pumping speed of the
pump is available.
The pumps are suitable for universal use due to their variable
differential pressure and flexible rotational speed. All pumps can be
used at ambient temperatures ranging from -20 °C to +40 °C.
In view of their magnetic coupling, OktaLine pumps are hermetically
sealed and achieve extremely low leak rates of 10-6 Pa m3/s.

The perfect
temperature,
every time
ydro-Thermal is the global
leader in on-demand steam
injection fluid heating, cooking,
and processing systems. These
heating systems are the most reliable,
durable solution for heating
water and slurries with instant
and precise temperature control.
Hydro-Thermal's newest inH
novation
is called the NOH, or
the Non-Obstructing Heater. The
NOH's straight-tube design allows for unrestricted flow, prevents
pressure drop, and heats slurries without plugging or fouling. In addition,
the NOH's rugged design and construction materials enable
it to handle viscous slurries, particulate-filled products, abrasive/
corrosive substances, stringy products, and inline water heating
abilities - all are possibilities with the NOH. Compared to other
heating systems, the NOH utilizes a smaller footprint, with direct
installation into the existing system piping- and does not require
special tools for maintenance.
Compact & Powerful: Ranging from 2 " to 12 " [DN50-DN300]
sizes, volume capabilities reach all the way to 6,900 GPM [up to
1,567.2 m3/hr].

BEUMER Group supplies
ship loading system
for urea fertilisers to
Malaysia: Perfect timing
S
ince the 1980s, Asean Bintulu Fertilizer (ABF), a subsidiary of
the leading Chemical manufacturer in Southeast Asia, Petronas
Chemicals Group Berhad, has a production location for carbamide
fertiliser (urea) in the Malaysian coastal city of Bintulu (Sarawak)
on the island of Borneo. To meet growing demands, BEUMER Group
was contracted to modernise and increase the performance of the
plant between the longitudinal stockyard and the ship loading system.
The scheduling was very streamlined.
" This order was a brownfield project, " explains Heinrich
Beintmann, Senior Project Manager at BEUMER Group. " This means
that we had to integrate our new systems into the existing ones in a
way that ensured that the material flow from the longitudinal stockyard
to the ship was not interrupted. " Another requirement was
that the already available hardware and software components from
third-party suppliers needed to be updated to match the increased
performance. " The maintenance of the entire system will become a
lot easier thanks to this modernisation, because all components are
on the same technical standard, " describes Beintmann. BEUMER
Group, in cooperation with PBJV Group, developed a technical solution
which they presented to ABF together with a schedule that met
all the required milestones.
