Abstract
The invention relates to a method and a system for heating natural gas, comprising the following method steps: a) supplying natural gas, which has a temperature in the range between −10 DEG C and 50 DEG C and a pressure of at least 30 bar, from a natural gas supply line to a first hollow chamber system of a heat exchanger, b) supplying a heating medium, which has a temperature in the range between 30 DEG C and 60 DEG C, to a second hollow chamber system of the heat exchanger, the first and the second hollow chamber systems being sealed from each other and relative to the surroundings, c) heating the natural gas in the first hollow chamber system to a temperature in the range between 20 DEG C and 150 DEG C by means of the heating medium in the second hollow chamber system, a plate heat exchanger being used as the heat exchanger and comprising at least two pairs of heat exchanging plates, at least the outer edges of the heat exchanging plates of each pair of heat exchanging plates being completely welded together, and d) leading away the heated natural gas from the first hollow chamber system to at least one further treatment step.
