WO2005110941A1 - Molasses treatment for the "molassperse ...

A method of treating molasses in which the molasses is modified to yield surfactants with plasticizer (water reducing) and dispersant properties. The essence of the treatment is that the molasses in the series is treated in acid and alkali environments at temperatures higher than ambient. This means that the ingredients of molasses are exposed to acid and alkali hydrolysis.

Clinkerization - Cement Plant Optimization

Clinker free lime (CaOf) should be as high as possible to avoid hard burning of clinker, but safely below value, inviting mortar expansion; normally, between 0.5% and 1.5%. Free lime indicates incomplete clinker burning, therefore should be monitored regularly and maintained closely in the acceptable range.
