Product Concentration, With Continuous Chemical Reaction


continuous-chemical-reactions
Problem: Carrying out an equilibrium reaction while simultaneously concentrating the reaction product and discharging a solid or a slurry – in a single step.

Solution: Artisan two-zone mechanically agitated thin film processors are used to carry out continuous reactions. The co-current design, with two zone process section, permits reaction, concentrating the reaction products and discharging a heavy slurry or solid – all in a single step.

Examples: Single stage saponification of isostearic acid with sodium hydroxide, forming a stoichiometric soap, and steam stripping the “unsaps” from the soap, discharging a paste purified soap with an acid value of 195, and an unsap value <1; also, esterification; acetylation; ketalization.
