The purpose of brownstock washing is to remove soluble matter from the pulp while using the least amount of water. Efficient washing improves the recovery of cooking chemicals, reduces the use of chemicals during bleaching, increase pulp quality and helps reduce deposit buildup. By utilizing a refractometer to measure the black liquor solids in the feed and outlet stock lines, and the incoming and outgoing filtrate lines, a paper company can experience increased control and cost savings.

The purpose of brownstock washing is to
remove soluble matter from the pulp while
using the least amount of water. Efficient
washing improves the recovery of cooking
chemicals, reduces the use of chemicals
during bleaching, increase pulp quality and
helps reduce deposit buildup. By utilizing a
refractometer to measure the black liquor
solids in the feed and outlet stock lines, and
the incoming and outgoing filtrate lines, a
paper company can experience increased
control and cost savings.
The MPR E-Scan gives paper companies the
ability to accurately control the washing
line, by detecting changes in the total
dissolved solids coming off the washers.
This precise measurement allows effective
control of the fresh water flow to the
washers, reducing excessive water usage.
Combining the measurement with data-
analysis tools, a company can monitor
inefficiencies in the washing line and
evaluate the washing results. Allowing
improvements in washing efficiency and
overall reduction in water. The MPR E-
Scan will reduce the overall time needed to
meet target dilution. With near instant
readings of black liquor concentration and
temperature, the instrument removes the
reliance on offline testing.
The MPR E-Scan is constructed of
various alloys to ensure a long service
life in a harsh chemical environment.
With our customer pipeline adapters,
the instruments can be implemented
into any process. Due to the unique
measurement principle, the instrument's
readings are unaffected by bubbles,
particles, fibers, color, flow, pressure or
vibration. By utilizing the instrument to
control and monitor the brownstock
washing, paper companies can
guarantee that proper dilution was met
and maintained.
