Enserve first introduced its emission monitoring service for the chemical and petrochemical industries in 2001. The company utilises Smart LDAR (Leak Detection and Repair) methodology, a revolutionary emission surveying technique that’s designed to locate, measure and limit volatile organic compound emissions. These volatile organic compound (VOC) emissions are harmful to the environment. Through infrared scanning techniques, the company locates vapour and gas leaks emanating from equipment, piping or valves. Enserve tags all process equipment and uses conventional gas monitors to measure and record leak concentrations. The company captures the data on IS tablets using state of the art locally developed software. Through the use of information captured on the tablets, Enserve produces leak reports that include the description of the plant equipment, leak information, losses per annum and visual evidence. Clients receive updated leak reports via a unique web portal.

The ultrasonic leak detection service compliments Enserve’s LDAR offering. The technology enables the company not only to detect leaks in the environment but also locate leaks in piping and passing valves. Ultrasonic leak detection also locates partial restrictions that affect the flow within pipelines. This service is particularly useful in finding the cause of obstructions in piping systems. These partial restrictions in pipelines affect working conditions in process plants and ultimately restrict productivity levels.

It’s difficult to spot a gas leak, especially in an industrial plant setting where legitimate background noises, as well as compressed air, mask the sound from a leak. The hunt for finding a leak proves to be a challenging task. The sound of the flow of gas that moves through different pressure systems emits sound within the ultrasonic frequency spectrum, which means the sound waves are at a higher frequency than usual and go undetected. But through the use of ultrasonic leak detection technology, this sound is reduced to an audible frequency. Unlike the human ear that fails to detect sounds emitted from leakages, ultrasonic detectors have the ability to a superhuman auditory capability that helps locate gas leaks over a mile away even in noisy environments.
