Lanemark Combustion Engineering
has installed a TX tank heating
system at Thomas Chadwick and
Sons, which supplies processed
blended wool worldwide from
Dewsbury, Yorkshire.
According to the supplier, the
process gas burner technology
is delivering tangible gains in
both energy usage and process
efficiency, compared to an older
system that it has replaced, with
the focus on the production of wool
grease, a natural by-product of the
wool washing operation.
It has designed, installed and
commissioned an elevated tank
and burner assembly located on a
gantry adjacent to the processing
operations.
Adrian Cadman, process burners
sales manager at Lanemark
Combustion Engineering,
describes the set-up. “This the
tank comprises three internal
chambers, which are progressively
filled with water mixed with
naturally-occurring wool grease
from the wool washing process.”
This byproduct is then sold on to customers
worldwide, particularly in the cosmetics
industry.
The three internal chambers, each one
cubic metre in size, sit within an outer tank.
The Lanemark TX 30 burner fires through
the tank wall into a 10-pass submerged
tube arrangement. This acts as a heat
exchanger for the internal tanks containing
the wash water/wool grease mix, raising the
temperature level to approximately 50°C
– which is said to be ideal to maintain the
fluidity of the separated wool grease.
Continues Cadman: “The products of
combustion are pulled through the tube
layout by a fan to ensure even and efficient
distribution of heat.”
From here, the by-product is discharged
into barrels for onward packing and shipping.
Around one tonne of wool grease is made
from 100 tonnes of wool processed every
day by Thomas Chadwick and Sons, part of
Standard Wool UK.
Cadman adds that the key elements –
burner, gas train, fan and control panel – are
fabricated from stainless steel. The burner
itself is also covered for protection during
washdown operations.
HRS helps
pharma fi rm
HRS Process Solutions has
recently provided a major
multinational pharmaceutical
company with heat exchangers
to cool Water for Injection
(WFI) at one of its production
facilities in Australia.
WFI is a key ingredient of
many pharmaceutical products
and can also be used in its
own right, for example to
irrigate wounds. Typically, WFI
is recirculated at temperatures
in excess of 75°C to prevent
microbial growth; however
the take-off points for product
manufacturing require WFI at
ambient temperatures.
HRS recently supplied
three heat exchangers to cool
WFI, which is then used at
various end points around the
Melbourne facility belonging
to the pharmaceutical
manufacturing organisation.
The facility uses technology
to produce advanced sterile
liquid medicines, which are
then exported to more than
30 countries worldwide. The
Melbourne site uses WFI as
the bulk excipient ingredient
in the formulation of sterile
pharmaceutical products, as
well as in equipment cleaning
processes.
