Abstract: An apparatus for managing tasks in an industrial plant comprises a task generator for generating at least one task to be performed in the industrial plant; a task scheduler for assigning a priority to each of the at least one task by analyzing the information of the plant; and a communication module for exchanging task information with a mobile device. The information of the plant may comprise static information and dynamic information of the plant. Preferably, the at least one task may comprise an event task dynamically generated by the task generator.

Abstract: The present invention relates to a method for providing a system for establishing a control valve performance in a process operation, said system including establishing an expected flow rate for a control valve by measuring a differential pressure between an upstream and downstream position of a control valve of interest and using the formula Q = Cv × φ ⁡ ( x ) × Δ ⁢   ⁢ P G , measuring an actual flow rate across the control valve, comparing the actual flow rate with the expected flow rate to determine the difference in value between the actual and expected flow rate, determining if the difference is within an acceptable range of values from the expected flow rate and establishing the performance of the control valve. The invention also relates to a system for establishing a control valve performance, said method including a flow meter to measure an actual flow rate across a control valve, a database having at least an expected flow rate for a control valve, and a comparator to compare the actual and expected flow rate to establish the performance of the control valve.
