Exxon Mobile PNG LNG
ExxonMobile PNG Limited's LNG facility.

Flow-Cal Inc., a market leader in measurement data management for natural gas and petroleum liquids, was selected to provide an advanced gas and liquids measurement solution at ExxonMobil Corporation’s Liquefied Natural Gas (LNG) plant in Papua New Guinea. The project, operated by ExxonMobil affiliate ExxonMobil PNG Limited, is an integrated development that is commercializing the gas resources of Papua New Guinea. The project includes a gas conditioning plant, and liquefaction and storage facilities with a large-scale capacity of 6.9 million metric tons of LNG per year.

ExxonMobil selected Flow-Cal’s measurement software solution to store and validate all gas and liquid values going into the PNG LNG facility. The flow computers used on the project poll data from each of the three PNG facilities and generate Flow-Cal’s secure CFX file format. The proprietary CFX format allows for the import of gas and liquid data into the FLOWCAL measurement application. Generating the file format within the flow computer offers an additional level of data security and integrity, FLOWCAL says.

New custom reporting tools and functionality were built into the FLOWCAL application to meet the PNG project requirements. The project required modifications to the API code within FLOWCAL to extend temperature, pressure and density ranges outside of the normal standards and trigger alarms when this occurs. Additionally, FLOWCAL increased their metric units support for gas and liquids with the addition of metric tons.
