As the popularity of natural gas has increased for heating and power generation, there has been strong demand for production and transportation of natural gas throughout the world. To transport natural gas around, it is liquefied using cryogenic processes to around -162°C and its volume is decreased by 600 times at LNG facilities to allow for safe and economic transportation, predominantly using LNG tankers.
Cryogenic processing of natural gas (mainly methane) is done in LNG liquefaction plants wherein the unwanted components (carbon dioxide, nitrogen, water, and a range of other unwanted components) are removed, and the heavier hydrocarbons separated prior to liquefaction and transportation. During this cryogenic processing, turbo expanders are used to remove energy from the LNG system and produce power at the same time.
Various machine trains are used in LNG plants during cryogenic liquefaction and compression processes. Vibration monitoring of these important machines is the most effective way of ensuring they are functioning efficiently and have no unscheduled downtime resulting in a loss of revenue.
Metrix Vibration provides the vibration monitoring systems which can enable LNG plant personnel to effectively monitor the machinery used in the cryogenic processing of natural gas. This includes the refrigeration trains, turbo expanders, and other rotating and reciprocating equipment used at the plant.
Metrix Cryogenic Proximity Systems are rugged and easy to install. These proximity sensor systems provide interchangeable parts, prevent cross talk, adjust pulse height to improve phase trigger and speed performance, provide high pressure feedthroughs, and have many other enhancements. IT is a 9, 10, 12 or 18-meter system that is designed to take advantage of the Metrix Digital Proximity System.
