Abstract: Systems and methods for isomerizing n-butane to form isobutane are disclosed. A segmented reactor system is used to isomerize n-butane. The segmented reactor system comprises a segmented reactor that includes a first catalyst bed and a second catalyst bed separated by a first heat exchanger. The catalyst in the first catalyst bed does not contact the catalyst in the second catalyst bed. During the exothermic process of isomerizing n-butane, the first heat exchanger extracts heat from an intermediate product flowing from the first catalyst bed to the second catalyst bed to improve the conversion rate of n-butane.

Abstract: A process for operating a chemical process includes deriving coefficients for a process performance model from historical feed data and historical production data; formulating the process performance model using the coefficients; determining a predicted change in production of a product of the chemical process using the process performance model; and changing a processing parameter of the chemical process based on economic data and the predicted change in production of the product of the chemical process.
