Thereafter, the mixture of the initial product and the emulsion preventing catalyst including the wash water is mixed for a T3 time (eg, 10 minutes) to settle the remaining by-products (S46).

Check whether the T3 time has passed (S47).

However, if the T3 time has not passed, the mixture is left to settle the remaining by-products (S46). If the time T3 has passed, turn on the third open / close valve (S48) and discharge the residual by-product (S49).
