INTELLIGENT STEAM TRAPS & STEAM TRAPS MONITORING
RELIEF & SAFETY VALVES MONITORING & ON-OFF VALVES MONITORING
Usual leakage rate of steam traps is 15% to 20% producing large economic losses in Refineries and Chemical Plants.
BiTherm's monitoring projects reduce leakage rate of steam traps below 0.5% permanently, generating steam savings between 15% and 30%.
Besides, BiTherm's monitoring projects significantly increase reliability of steam networks, a benefit difficult to quantify but of enormous value in avoiding unscheduled shutdowns of Process Plants.
The following diagram shows the powerful topology of the SmartWatchWeb™ system:
Its great advantages lie in its extraordinary reliability and flexibility, which makes it possible to extend the monitoring system to tens of thousands of steam traps managed under a platform common to all of them. This greatly reduces installation and maintenance costs.
Intelligent steam traps, steam traps monitoring, safety & relief valves monitoring, and on-off valves monitoring detects steam leaks, gas leaks, and other incidents in real time to correct them with diligence, and thus reduce energy consumption, increase reliability and reduce production costs, inspection and maintenance.
MONITORING (TOTAL OR PARTIAL) OR ALARM SYSTEMS
Unlike alarm systems that do not allow to analyze evolution or trend, monitoring systems send not only alarms, but also measurements of parameters with scheduled frequency, so that users can perform historical analysis of evolution and predict trends.
Total monitoring of steam traps requires following sensors:
♦ Ultrasound: To detect internal and / or external steam leaks.
♦ Temperature: To determine the steam trap energy efficiency and / or low temperature due to excessive accumulation of condensate.
♦ Back pressure: To detect excessive pressurization in condensate return pipelines.
Highlight the importance of the back pressure sensor because the most serious operational problems in steam traps occur as a consequence of excessive pressurization in condensate return pipes, caused by excessive expansion steam formation in steam trap discharges, added to the leakage of live steam through it.

LIMITATIONS OF ULTRASOUNDS
The detection of ultrasound has become a tool of great predictive maintenance value for the detection of gas or steam leaks in valves. However, it is necessary to know its limitations when applied to vapor leak detection in steam traps, where condensate discharge generates flash steam that can be misinterpreted as a live steam leak.
