Fluid Components International (FCI) has launched its next-generation air/gas flow meter to measure boil-off gas (BOG). The ST100 Series Thermal Mass Air/Gas Flow Meter helps enable ship propulsion systems operate efficiently while complying with International Maritime Organization (IMO) regulations.
LNG tanker fleets are unique because LNG cargo generates waste gas, commonly known as BOG. In order to transport natural gas, it is economical to convert it to LNG. The conversion process involves cryogenically cooling the natural gas to -163°C at atmospheric pressure, at which point the gas condenses to a liquid and is ready for transport. BOG results when the LNG vaporizes due to subsequent ambient heat input during transport.
In recent years the ships have been using the LNG BOG that is produced during transport as fuel for the ships boilers. On January 1, 2013 the International Maritime Organization (IMO) implemented an amendment to the International Convention for the Prevention of Pollution from Ships whereby they added a new regulation to increase the energy efficiency for ships in order to reduce the CO2 emissions that are a cause of global warming. Accurate flow measurement of BOG piped to the boilers is critical to help the boilers run more efficiently.
The ST110 Series Flow Meter from FCI meets the accuracy requirements for measuring BOG aboard tankers, at land terminals, storage facilities and points of distribution. This advanced air/gas flow meter combines powerful electronic features and an advanced flow sensor design to provide precision measurement, reliability and economy. The ST110 includes system wide agency approvals for hazardous environments, and a rugged, NEMA 4X/IP67 rated 316 stainless steel enclosure.
