ON-SITE seminar: Hydrocarbon cracking is one of the vital processes in refineries. Complete understanding leads to ability for design, optimization and control that result to engineering and financial excellence. Environmental regulations, legislation and ethics also call for advanced control of hydrocarbon cracking and minimization of energy consumption and material loss. Catalysis and catalytic cracking processes constitute the cornerstone of hydrocarbon cracking. This scientific seminar focuses on hydrocarbon cracking, catalysis and catalytic processes principles and Fluidized Catalytic Cracking simulation and optimization.
