The manufacturer prepares paint accurately in reactor tanks according to formulations but the blue paint has slight color variation between batches. As an industrial chemist, how could the variation be reduced or eliminated to consistently produce the same blue color? Accurately measuring ingredients and improving ability to handle variations in density, viscosity, and air could help produce consistent batches and reduce waste.

3. A manufacturer of paints prepares accurately the
paints in reactor tank according to formulation for
the paints. For example, the paint is blue. However,
every time an order is made by the contractor using
this paint, he is happy with the colour for that batch.
When he order the next batch, he found that the
blue has slight variation in colour. As an industrial
chemist, how would you reduce or eliminate the
colour variation?

8. • Micro Motion meters can accurately measure the various
ingredients in any paint formulation.
• Variations in density and viscosity have no effect on
modern Coriolis meters.
• As well, dramatically improved ability to “batch from
empty” and handle greater amounts of entrained air in
continuous processes boosts meter performance.
• Sensors such as F-Series, optimized for self-drain ability
improve any process where the line cannot remain full of
fluid.
