WEIXIAN sulphonation/sulfonation plants represent the highest level in the industry. So far, we are able to provide from a one-tube pilot plant to a 10t/h mass production plant. Among 200+ projects we have done, the majority of them were on a turnkey basis, including but not limited to:
- LABSA (sulfonic acid) prodcution line
- SLES production line
- SLS production line
- AOS production line
- HABSA production line
- MES production line
- SLS/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 consumption are superior to that of competitive plants.
