The LABSA (linear alkyl benzene sulphonic acid) from the separator goes to the aging vessel by first discharge pump, then stabilized in the stabilization pump with water. After cooling, the LABSA will be pumped to the finished product tanks by the second discharge pump. The liquid level of the aging vessel is controlled by a level transmitter and VFD of the second discharge pump.

Features: WEIXIAN aging vessel is a vertical and static mixing type, with no back-mixing and the aging time can be controlled, which makes it closest to the theoretical limit of aging conversion rate, and reduces the free oil content and sulfate acid content to the minimum, while correspondingly improves the active matter content close to or reach 98%.
