Vapor Pressure Curves are sources of process information used by INSPECT to help determine a critical region of the integrity operating window. INSPECT combines equipment MSOT and Vapor Pressure Curves to help operators consider the risk of auto refrigeration induced brittle fracture and ensure safe operations.
INSPECT provides a Vapor Pressure Curves library that covers fluids commonly used in the process industries. In Addition, INSPECT includes the ability to specify custom Vapor Pressure Curves. INSPECT plots the selected Vapor Pressure Curves on the MSOT curve to identify process conditions that exceed the equipment’s MSOT.
In addition to being plotted in the MSOT, Vapor Pressure Curves in tabular form are also presented in the summary report.
