Appendix 4 CTL Technology Options The principal technologies selected by Jacobs during the Pre Feasibility Study for the expandable CTL/Power Plant are: Conoco Phillips (CoP) Technology for

Rentech Technology for FT Synthesis selected as one of only two technologies available for third party use.

38 Appendix 4 CTL Technology Options The principal technologies selected by Jacobs during the Pre Feasibility Study for the expandable CTL/Power Plant are: Conoco Phillips (CoP) Technology for Gasification selected following a techno-economic evaluation of 4 leading commercial gasification technologies currently available worldwide. Rentech Technology for FT Synthesis selected as one of only two technologies available for third party use. (Jacobs has worked with Rentech on various projects and has detailed data on the technology) UOP Hydro treating and Hydro cracking Technology for Product Upgrade considered as the best suited processes for upgrading Rentech s FT crude products (UOP, Rentech and Jacobs have worked closely over many years to develop and optimise the process conditions of the Product Upgrade Unit to maximise diesel fuel production) Jacobs advises that CoP, Rentech and UOP are world class leaders in their respective technologies, and believes the technologies proposed for the CTL/Power Plant will be well suited and competitive in world terms 38
