In 2014, SL TEC has built a crude phenol purification plant for Fulltime depending upon its experienced capability in chemical process simulation and the R&D results in the on—site factory of Fulltime. This plant has been using coked crude phenol as the feedstock, which has to be dehydrated and deslagging. In 2016, SL TEC offered to revamp this plant by changing the feedstock from the coked crude phenol to the post-treatment phenol mixture, which not only simplify the phenol purification route, but also reduces the generation of effluent.
Besides, in 2016, SL TEC has taken to build a new m-cresol and p-cresol separation plant, 2,4-dipentylphenol plant, 4-tert-octylphenol (also called as p-t-octylphenol) plant, 2,4-dicumyl phenol plant and 2-cumy-octylphenol plant.
