You can never take the safety of the workers and the plant lightly especially in petrochemical industry, oil rigs, and other manufacturing units. The inflammable and toxic gasses can cause serious harm not only to humans and animals but also the environment at large. That is the reason, all industries must initiate a predictive maintenance schedule in place to be aware of any faults before it is too late.
One of the most common techniques used in plants is to check for gas leaks. There are various types of equipment used for doing these tests. Gas detectors are the most common devices used to the recognize gas leaks.
This device is commonly a part of the safety system of any maintenance kit.Not all gasses are accompanied by odor making it difficult to identify a leak before it is too late. But these devices can detect all kinds of gas leaks and emissions. It sounds an alarm when it detects a leak giving the workers opportunity to escape from the peril at hand.
Some of these devices use ultrasound to detect leaks, they have acoustic sensors which recognize the change in the background noise and identify high-pressure gas leaks. use acoustic sensors to detect changes in the background noise of its environment.
These devices produce an alarm when they detect any abnormal deviation in sound from the normal background noise. They cannot detect the exact concentration of a gas in the leak, they can merely point out the fact that there is a leak and determine the leak rate.
These devices are predominantly used outdoors for remotely sensing gas leaks. Usually, because of the weather, the gas fails to connect with the normal sensors and therefore no alarm is set off. This is a hazardous situation for any plant necessitating the use of the ultrasonic devices.
These devices are commonly found on all offshore and onshore oil or gas platforms, gas stations, gas turbine power plants and any other facility that uses gas or external pipelines.
