Detal Project – Puente Mayorga

New project to improve and expand production at Cepsa’s Puente Mayorga Chemical Plant, located in Roque (Cadiz). For this project, Cepsa asked Sacyr Fluor to conduct a Consistency Analysis of the Basic Engineering performed previously by UOP (first stage of the Project), and to provide Detailed Engineering, Permit Management Support and Procurement Support services. 
In addition to the scope indicated in the previous units, Sacyr Fluor also provided the Engineering for a new Paraffin Storage Tank and an Associated Pumping System, Fire Protection System, and redesigned the  Gas Flare System. The project encompassed two new units (PEP-DETAL and PACOL) and the modification of another existing unit.
The project entailed a revamping process that, as well as increasing the plant’s production capacity from 200,000 to 250,000 tons, also involved installing Detal technology, developed by Cepsa and UOP, and the most modern and efficient technology for the production of  Linear alkylbenzenes (LAB).
