In any process plant, the hassles of effective steam utilisation are invariably associated with the performance of the process traps. The process traps play an important role in maintaining uptime of the plant, and steam trap performance is generally a matter of concern for operators and utility managers. Regular/ periodic checking of traps is required to ensure smooth functioning. However, this exercise is not easy to carry out owing to the sheer volume of traps in any process plant.

Concerns regarding steam trap performance

The exact status of steam traps across the plant can be quite ambiguous, and personnel are often faced with concerns like

- Are all the steam traps working properly or not?

- At what frequency should the steam traps be checked?

- Is the steam trap status being determined correctly, using the right methods?

- How can status of steam traps in a closed loop be ascertained?

Several surveys and energy audits conducted by Forbes Marshall across plants in various industry sectors indicate that inspection of the steam and condensate system is not conducted regularly, and almost 20 to 30% of steam traps are observed to be wasting steam. Therefore, continuous monitoring is required to maintain the uptime of the steam traps.

Steam trap failure and impact

A steam trap can fail in open condition or in closed condition, and hamper the process as illustrated below.

The Forbes Marshall Solution

The Forbes Marshall Trap Monitoring System (FMTMS) is an innovative solution to automatically detect and indicate health of steam traps. The FMTMS monitors the operation of steam traps at regular intervals. It diagnoses the exact status of the trap in real time, eliminating the ambiguity surrounding trap functionality.

The operating personnel can easily determine the status of individual steam traps through a multi-color LED that flashes to indicates the health of the trap.

Working Principle of the Forbes Marshall Trap Monitoring System

This monitoring device is battery-operated and measures the conductivity of the fluid medium inside the steam trap, as well as its temperature.

The electronic unit interprets the value inputs of conductivity and temperature and generates an alert through a multi-color light.

The different colours of the light correspond to the health status of the steam trap as indicated below

Benefits

The FMTMS is an intelligent solution for steam trap monitoring at equipment level. It automatically detects and indicates the health of steam traps in real time, delivering optimum uptime. Monitoring is done at regular intervals, without the need for manual intervention.
