SEQENS Solvents & Phenol Specialties (SPS) is an European leader manufacturer of high quality Iso Propyl Alcohol (IPA). Our plant is based on the hydrogenation technology of high purity grade Acetone, fully integrated by the local Cumene-Phenol-Acetone plant. Started in 2010 with an initial capacity of 30 Kt py, Seqens IPA plant now reaches an overall production capacity of more than 70 Kt py.
