Debottleneck SF5 is an engineering project by LyondellBasel to debottleneck the SF5 plant in Ferrara, Italy. The SF5 plant manufactures support materials for Ziegler–Natta catalysts, which are used in the production of polypropylene and other polyolefins. The objective of the project is to increase the plant’s production capacity from its existing level to approximately 1,750 tonnes per year, while keeping the facility ready for future expansion to 2,200 tonnes per year.
