IMPROVED SYSTEM FOR PROCESSING AND DELIVERING NATURAL GAS COMPRISING A CIRCUIT FOR HEATING THE TANK

摘要

The invention relates to a system for treating and supplying natural gas comprising: a circuit for feeding an apparatus for generating power, which is selected among a heat engine, a fuel cell or a gas turbine, and which makes it possible to supply natural gas from a liquefied natural gas storage tank (2) to said apparatus for generating power (4, 6), said supply circuit comprising an upstream portion connected to the tank (2) and a downstream portion connected to the apparatus for generating power (4, 6); a circuit for feeding a burner (5) making it possible to supplying the natural gas from the tank (2) to the burner (6) comprising an upstream portion connected to the tank (2) and a downstream portion connected to the burner (5); a circuit for heating the tank (2) capable of collecting a gas stream at the bottom of the tank (2) and injecting same at the top portion of the tank (2), said heating circuit comprising an upstream portion connected to a pipe (52) leading into the bottom portion of the tank (2) and a downstream portion connected to a pipe (71) leading into the top portion of the tank (2).
