When producing SLES, the sulfate needs to be neutralized with pure water, caustic soda, H2O2, and buffer in the neutralization reactor, all materials react by high-speed mixing, then remove dioxane together with air in the stripping tower under vacuum condition, meanwhile, the cooling procedure is also done in this tower.
Features: Compared with Italy's vacuum neutralization, WEIXIAN stripping tower is a static equipment, without motor and maintenance requirement. Before going into the stripping tower, products react in the micro positive pressure reactor, so there is no acid gas corrosion happened in condensate and vacuum pump. Meanwhile this unit has a 10 times SLES recycle loop, comparing to similar technologies of other suppliers, this process makes the neutralization temperature rise less than 5℃, which helps us to get the products with lighter color, more stable pH value and lower dioxane content. This unit is able to realize ultra-low dioxane content.
WEIXIAN sulphonation/sulfonation plants represent the highest level in the industry. So far, we can provide from a one-tube pilot plant to 10t/h mass production plant. Among 200+ projects we have done, the majority of them were turnkey basis, including but not limited to:
· LABSA (sulfonic acid) production line · SLES production line · SLS production line · AOS production line · HABSA production line · MES production line · SLS/AOS/sulfonic acid sodium salt drying units · Other anionic surfactant production lines
By adopting state-of-the-art designs and processes, all the performance aspects including plant reliability, finished product qualities, and unit raw material/power consumption are superior to that of competitive plants.
