In-situ process for the monitoring of localized pitting corrosion

Pope, Daniel H.; Lin, YuPo J.; St. Martin, Edward J.; Frank, James R.

Title: In-situ process for the monitoring of localized pitting corrosion

Abstract

A method and apparatus are provided for monitoring localized pitting corrosion in metal pipes or storage vessels. Electrochemical probes are used for sensing electrochemical noise voltage values and electrochemical noise current values. The root-mean-square electrochemical noise current and voltage values are calculated and stored for the sensed electrochemical noise voltage values and the electrochemical noise current values. The stored electrochemical noise current and voltage values are processed by transforming the stored electrochemical noise current and voltage values into power spectral density data utilizing a fast Fourier transform. A slope of the power spectral density data relative to frequency is calculated. The electrochemical probes include a pair of working electrodes formed of the same material of the monitored metal pipes or storage vessels and a reference electrode formed of a corrosion resistant material. A linear slope of a low-frequency portion of the power spectral density data is calculated by using a least-square method.

High resolution in situ ultrasonic corrosion monitor

Patent Grossman, Robert J [Schenectady, NY]

An ultrasonic corrosion monitor is provided which produces an in situ measurement of the amount of corrosion of a monitoring zone or zones of an elongate probe placed in the corrosive environment. A monitoring zone is preferably formed between the end of the probe and the junction of the zone with a lead-in portion of the probe. Ultrasonic pulses are applied to the probe and a determination made of the time interval between pulses reflected from the end of the probe and the junction referred to, both when the probe is uncorroded and while it is corroding.

Determining the locus of a processing zone in an in situ oil shale retort by sound monitoring

Patent Elkington, W Brice [Grand Junction, CO]

The locus of a processing zone advancing through a fragmented permeable mass of particles in an in situ oil shale retort in a subterranean formation containing oil shale is determined by monitoring for sound produced in the retort, preferably by monitoring for sound at at least two locations in a plane substantially normal to the direction of advancement of the processing zone. Monitoring can be effected by placing a sound transducer in a well extending through the formation adjacent the retort and/or in the fragmented mass such as in a well extending into the fragmented mass.

In-situ localized growth of porous metal oxide films on microheater platform for low temperature gas detection

Patent Maboudian, Roya; Long, Hu; Harley-Trochimczyk, Anna; ...

A solid-state, low power microheater sensor platform that is configurable with selected metal oxide films for particular gas sensing applications is described. The sensor platform is configured by selecting a chemiresistive or catalytic material that is suitable for detecting a desired gas and then forming a porous nanostructured film on the designated surfaces of the microheater platform. Also described are methods for creating a highly porous, nanostructured metal oxide film in a controlled location from a liquid precursor using a localized heat source. By fast annealing deposited liquid precursors with the microheater, a highly porous, nanocrystalline metal oxide film canmore »« less

An electrode design is provided for corrosion monitoring using electrochemical noise measurements. Electrochemical probes are used for sensing electrochemical noise voltage values and electrochemical noise current values. The electrochemical probes include a pair of working electrodes formed of the same material of the monitored metal pipes or storage vessels and a reference electrode formed of a corrosion resistant material. Each of the pair of working electrodes has a defined surface roughness. One of the pair of working electrodes has reduced roughness, whereby sensitivity to sustained localized pitting corrosion is increased in the working electrode with reduced roughness.
