Abstract: A method of optimizing system parameters in a crude unit to reduce corrosion and corrosion byproduct deposition in the crude unit is disclosed and claimed. The method includes measuring or predicting properties associated with the system parameters and using an automated controller to analyze the properties to cause adjustments in the chemical program to optimize the system parameters. Adjusting the system parameters effectively controls corrosion in the crude unit by reducing the corrosiveness of a fluid in the process stream and/or by protecting the system from a potentially corrosive substance. System parameter sensing probes are arranged at one or more locations in the process stream to allow accurate monitoring of the system parameters in the crude unit.

Abstract: A method of correcting measurements of a chemical sensor used in an industrial facility. The method involves correcting for errors known to occur in the steady state and the dynamic state for specifically recognized situations. This method allows for correcting errors that occur due to deadtime, false zero measurements, and non-linear disturbances. The method combines automated measurement techniques and human know how to progressively learn and refine the accuracy of the corrections.

Abstract: An apparatus of provided for simulating corrosion activity of a high temperature liquid stream. The apparatus includes a canister in which is positioned a plug, occupying part of the internal volume of the canister. A stream of high temperature liquid enters the canister through an inlet, flows around the plug, and exits the canister through an outlet. The volume and configuration of the plug may be varied to simulate corrosion activity under various flow regimes. Probes may be placed in the liquid stream to detect corrosion activity and temperature. Several canisters may be arranged in series, and corrosion activity may be simulated in each canister simultaneously to determine effects of various parameters such as liquid impingement, velocity, and temperature on corrosion activity.
