Achievement of zero flaring during liquefied natural gas (LNG) offloading operations is governed by many factors. The proper management of the balance of fuel gas and boiled-off gas (BOG) between the floating LNG (FLNG) facility and the LNG carrier (LNGC) is critical during offloading to ensure that the system reaches equilibrium, leading to zero flaring. The complete paper details a process study to identify potential causes of flaring during LNG offtake and corrective measures to accomplish zero flaring without any capital plant modification. The study is applicable only for offloading operations to LNGCs with spherical Type B LNG tanks.
Introduction
PFLNG Satu (referred to hereafter as PFLNG1) performs LNG offloading to an LNGC on a monthly basis.
