Today, information is expected to be instantaneous. We are used to “Googling” for information and receiving instant results, sometimes more than we imagined. Online monitoring systems in refineries check temperature, pressure, flow, motor condition, and many other aspects of fixed or rotating equipment.
The Inspection department, typically involved in mechanical-integrity programs, have used ultrasound thickness measurements for many years to help access the mechanical aspects of pipes, vessels, tanks and other fixed assets in a refinery. UT thickness surveys performed manually take planning and scheduling with other departments. In some instances, scaffolding needs to be erected, inspected and/or insulation removal. Careful safety procedures such as fall protection, confined-space entry, H2S, or other gas monitoring must be performed prior to and during the UT inspection. Scheduling, time and cost go into a simple 3-minute UT thickness survey for one location (TML).
The ultrasonic thickness data monitored by this system is also valuable to the corrosion department and the operation’s teams. Departments monitoring system corrosion utilize many devices to measure and control metal loss of refinery units. Managing corrosion coupons, intrusive corrosion probes metallurgical evaluations, and other tools for determining the corrosive aspects of the contents of a pipe or vessel. Using continuous thickness data as a complementary technique can give technicians another tool to monitor and address corrosion issues.
Utilizing the information from a network of installed corrosion monitoring sensor system provides these organizations with on-demand information regarding the wall thickness of a component and changes in wall thickness for everyone along the value chain which allows them to do their job more effectively. Working together, the inspection, corrosion and operations teams can utilize this same thickness data in different ways to get the maximum value and streamline plant operations.
Sensor Networks’ installed UT sensors and software provide refining and other downstream process facilities with a flexible non-intrusive ultrasound wall thickness monitoring system. Data acquisition periods can be individually configured per location based on historical component failures, high-risk situations and limited or dangerous-to-access issues.
Typical Applications include:
Refinery systems with high risk, history of failures or changed processing parameters. New or refurbished plant components.
