Sec-butyl Acetate Plant

There are two prevailing processes for sec-butyl acetate (SBA) production, i.e.
iso-butanol-acetic acid esterification process and n-butene -- acetic acid
addition process. Due to its much lower production cost, new SBA plants usually
use the Addition Process, which is the very technology SL TECH provides. It
consists of four units, feedstock purification unit, esterification unit,
product separation unit and acetic acid recovery unit. Compared to the
Esterification Process, the Addition Process for SBA production has advantages
such as shorter process flow, less equipment and lower production cost (50-60%
of Esterification Process); lower energy consumption (only 5% of Esterification
Process); easy operation, lower maintenance cost and lower operation cost;
harmless and poisonless solid acid catalyst, less pollution, less equipment
corrosion.
