Advances in EO catalyst performance have given rise to improved capital-efficient processes.
In terms of EO/EG plant design, there are various operational parameters, as shown in the chart below, that can have conflicting effects on feedstock use related to catalyst selectivity, capital expenditure, and energy use. For example:
Shell Catalysts & Technologies has developed and applied an integrated tool to help plant designers predict the total EO production costs for a given catalyst and plant design. This can contribute to:
