Tall oil and soap separation improvement
Resin- and fatty acid blend create problems in brown stock
washing area and will increase defoamer and bleaching chemicals
consumption. Therefore, it is important to separate soap in the
right position and most optimal way. Critical factors for good soap
separation are, amongst others
•
Temperature
•
Dry content
•
Separation time and process construction
•
Residual alkali
•
Salt content
Even if all process parameters are optimised, some of the soap will
still be dissolved in the black liquor. This will cause fouling in the
evaporation area. By adding chemistry to the mixing liquor going into
the separation tanks, the equilibrium will be changed and more soap
will be subjected to separation. This will lower the risk for fouling and
decrease the load on the recovery boiler. If there are no other bottle
necks white liquor production can be increased significantly.
Working together for a more sustainable future
We all have a responsibility to commit to a positive and
greener future and the pulp and paper industry has an opportunity
to make a real impact. Together, pulp producers and chemical
suppliers can contribute to make life on earth more sustainable,
healthy and inspiring by focusing on creating more value from fewer
resources and use the world’s limited resources more efficiently.
In switching to a more sustainable pulp production, you
should be able to expect close support and consultancy from
application specialists at your chemical partner. This support should
range from identifying the specialty chemical applications needed to
process setup and optimisation.
At BIM, we are aware of the chemical industry’s role in
the history of modern eco-movement. We also have insight in the
huge potential we as a supplier of chemicals within the pulp and
paper industry have of being an enabler of a sustainable future,
e.g. to enhance our customers’ energy, water and fibre efficiency.
We believe that our knowledge and experience should be used
as a driving force in the continuous development within the pulp
and paper industry. Our expertise is founded on a number of core
competences and technologies, which lead to the development of
green specialty chemical-based concepts, technology and service
for the pulp and paper industry’s products and processes.
By working in close cooperation, we believe that producers
and chemical suppliers can play a central part in making every daylife more comfortable, healthy and inspiring. But it’s not enough to
merely talk about this aim; we must actively work to achieve it. And
we must do it now.
CONCLUSION
BIM is a family-owned, entrepreneurial chemical company supplying the pulp- and paper industry since 1973. With a customerfocused research and product development, we develop innovative specialty chemical concepts designed to improve products
and processes in a cost-effective and sustainable way. We focus on creating more value from fewer resources to use the world’s
limited resources more efficiently.
