Leak detection is very important for safe transportation of hazardous chemicals.
Several types of leak detection technologies are available
Non- Continuous leak detection systems - Inspection by helicopter Smart pigging Tracking dogs
Continuous leak detection - Two types of continuous leak detection are there 1.Hard sensor 2.Soft sensor
Hard Sensor- Fiber optic cable Acoustic system Sensor hoses Video monitoring
Soft sensor- Balancing method Statistical systems RTTM method (Real time transient model) E-RTTM method
What is a soft sensor? Made up of the words software and sensor Intelligent softwares uses existing sensor to generate new information
Intelligent soft sensors offer additional information- Detection of a leak Localisation of leaks Linepack Product tracking in multi-product applications Life cycle monitoring Calculation of pipeline efficiency Monitoring of vapor pressure and stack line conditions along the pipeline Over-pressure violation along pipeline.
