Glycerine loss in evaporator of treated lye (glycerol solution from the soap process), is one of the most significant problem in the glycerine recovery process of the soap manufacturing. It can be lost by being carried over as droplets, foam, or, if a serious prime occurs, as bulk liquid. This thesis is experimented in the actual process in soap plant (on-line experiment) by improving the separator or external “catchalls” and the operating condition to minimize the lose that is occurred for a long time from the process start up. The experimental results were satisfied and promising, it could reduce the glycerine loss from 11%-18% in 1985 to the first half of 1991 to 1% in the second half of 1991 after implementation of an improvement.
