To remain competitive, today’s refiners must employ all optimization and product control techniques available. The use of online physical property analyzers is one of the key features to reach those objectives because they measure important quality properties in the process directly.The freeze point is the temperature at which the last of the wax crystals disappear when warming the sample, after first reaching the Cloud Point temperature.
