The alkylation process takes place in the presence of an acid - in the Dangote refinery, this is sulphuric acid (H 2 SO 4). The plant is called a sulphuric acid alkylation unit (SAAU). [54] The main technology for SAAU is the STRATCO process licensed by DuPont. It is a very established technology for alkylation in refineries.
