摘要： 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.

摘要： An apparatus for hydrolytic degradation of plastics in which plastic material is deposited into a tubular housing via a feed hopper. An elongated screw shaft has a first section in the form of a high pitch screw thread disposed below the feed hopper to receive and advance the material to a second section. The second section of the screw shaft is in the form of a lower pitch thread for compressing the plastic material and transferring it to a longer, third section in the form of kneading discs, from which material passes through an outlet nozzle section to a cyclone separator where trapped gases and liquid may be withdrawn. The tubular housing is vented upstream of the feed hopper and a water inlet pipe is disposed adjacent to the second section of the screw shaft, downstream of the feed hopper. The outlet nozzle section is provided with pressure measuring and regulating means and a liquid level measuring and regulating device.
