By integrating these technologies, calcium chloride manufacturers can achieve better process control, improved equipment reliability, and more efficient plant operations.
Understanding the Calcium Chloride Manufacturing Process
Before exploring the benefits of automation, it is important to understand the major production stages of calcium chloride manufacturing.
Calcium chloride can be produced through different industrial routes, including the recovery of calcium chloride from process brines and the reaction of limestone with hydrochloric acid.
A common manufacturing route involves reacting calcium carbonate (limestone) with hydrochloric acid (HCl) to produce calcium chloride, carbon dioxide, and water.
Chemical Reaction:
CaCO₃ + 2HCl → CaCl₂ + CO₂ + H₂O
Depending on the manufacturing process and desired final product, production typically includes the following stages:
