Development of a synthesis tool for Gas-To-Liquid complexes

► The complexity and trade-offs in design of GTL processes are highlighted. ► Conversion technologies with syngas recycle structure options in GTL are explained. ► A GTL process synthesis model is formulated for MINLP optimisation. ► An automatic initialisation procedure ensures a good starting point for the Non Linear Programming solver. ► Already in a small example the benefit of the tool has been proven.
