Specialty Chemicals

Specialty Chemicals are usually manufactured in batch chemical plants using batch processing techniques.
Specialty Chemicals

A batch process is one in which a defined quantity of product is made from a fixed input of raw materials during a measured period of time.

The batch process most often consists of introducing accurately measured amounts of starting materials into a vessel followed by a series of processes involving mixing, heating & cooling, making more chemical reactions, distillation, crystallization, separation, drying, packaging etc., taking place at predetermined and scheduled intervals.
