Description

The focus of work during this reporting period was the construction of an automated probe that will be used to measure the thickness of coke deposits in thermal cracking furnaces. A discovery was made during the last reporting period, which indicated that a conventional NDE broadband transducer could be used in conjunction with a sacrificial standoff composed of a fusible alloy to efficiently couple the transducer to a rough surface operating at high temperature. A probe was constructed that incorporates the recent discovery and initial testing of the probe is now underway. Successful development of the coke detector will provide ... continued below

Description

The focus of work during this reporting period was the construction of an automated probe that will be used to measure the thickness of coke deposits in thermal cracking furnaces. A discovery was made during the last reporting period, which indicated that a conventional NDE broadband transducer could be used in conjunction with a sacrificial standoff composed of a fusible alloy to efficiently couple the transducer to a rough surface operating at high temperature. A probe was constructed that incorporates the recent discovery and initial testing of the probe is now underway. Successful development of the coke detector will provide industry with the only available method for on-line measurement of coke deposits. The coke detector will have numerous uses in the refining and petrochemical sectors including monitoring of visbreakers, hydrotreaters, delayed coking units, vacuum tower heaters, and various other heavy oil heating applications where coke formation is a problem.
