Abstract

A system and associated method for controlling the operation of a cryogenic cogeneration system with an expander (150) using heat from an external heat source (1000) is described. The system comprises a processor configured to execute a control program including software commands, the software commands chosen to perform selected actions, including receiving data related to various process parameters and components of a cryogenic cogeneration system, determining the values of selected process variables, comparing measured parameter values to setpoints and/or process variables, and providing control commands to various components of the cryogenic cogeneration system to optimize operation of the cryogenic cogeneration system.
