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%. 

Unlike the former rotating type with an agitator, ours is a static type, which is featured in more homogeneous aging effect with no back-mixing. By adopting a special inner structure, each material molecular in the static aging vessel will have equal residence time (staying time). On the contrary, the residence time of each molecular in a rotating aging vessel is uneven, which shows a normal distribution. Our aging time is adjustable from 0-60 minutes by controlling the liquid level in the vessel. Normally, the aging time is set to be 30 minutes; when a higher active matter percentage is required, for example, 97.5% - 98% LABSA, the aging time can be set to 45 - 60 minutes. Besides the performance, power consumption and maintenance requirements are reduced due to the nature of static equipment.
