Abstract
A contactor for the transfer of matter and heat between gas and liquid comprising a helical support of heat conductive material allowing the flow of a liquid to be treated, a wall of heat conductive material and in thermal contact with the said support, separating in sealing-tight manner the said liquid and a heat exchanging fluid, characterized in that the said support and the said wall are formed by a vertical stack of open work plates of a heat conductive material, offset angularly in respect of one another by rotation according to the axis of the said support, each plate thus forming an element of the said support, like a step of a spiral staircase, and an element of the said wall, in such a way as to obtain an economical and efficient evaporator or absorber.
