Metrix LNG Cryogenic Proximity Systems
March 2, 2022LNG Turbo Expanders and Other Cryogenic Systems
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 the world, 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. Metrix Vibration has the best speed and position monitoring for these cryogenic applications.
Vibration Monitoring of LNG Cryogenic Systems
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.
This application page and the attached documents are intended to outline the specifics regarding the speed, vibration and position systems used in LNG Cryogenic applications.
The Metrix Cryogenic Proximity Systems are rugged and industry proven proximity sensor systems. From the factory, Metrix has done several things to help ensure the proximity systems are easy to install and provide excellent data – such as providing interchangeable parts, preventing cross talk, adjusting pulse height to improve phase trigger and speed performance, providing high pressure feedthroughs and many other enhancements. Please refer to the Documentation tab below to learn more.
The Metrix Cryogenic Proximity System is a 9, 10, 12 or 18-meter system that is designed to take advantage of the Metrix Digital Proximity System.
