Abstract
The invention relates to a means for heating the charge of a catalytic reforming unit operating under low pressure. The invention more particularly relates to an apparatus having in combination a first heat exchanger (6), in which a recycling gas/liquid charge mixture introduced by pipe (5) is completely vaporized, and a second exchanger (9) in which the charge is heated to an adequate temperature by indirect contact with reforming effluent delivered by pipe (17), which successively passes through the two heat exchangers.
