Abstract
The invention relates to a multiple phase flow tube for evaporating and reacting components in compound mixtures in which a spiral pipe is arranged within a multiple phase flow pipe. The components are propelled by means of an internally flowing gas stream in an annular shaped passage formed by a spiral tube and a second tube arranged as a core of the spiral tube. The second tube contains a heat exchange medium. The spiral tube is arranged within a cylindrical casing which contains a heat exchange medium. A gaseous stream of a reduced amount is then sufficient for carrying out the particular chemical process desired.
