    Abstract: Process for the spraying of a liquid by means of a gas into a fluidized bed, in which process said spraying is conducted by means of a two-phase spraying device, consisting of a liquid feed tube (21) fitted concentrically in a gas feed tube (26), in which device the end face of the liquid feed tube and the inner wall of the part of the gas feed tube extending beyond this end face are chamfered at an angle of 70-90 so that between this face and this wall there is a conical channel, and this inner wall connects, via a rounded area, to the inner wall of an outflow channel fitted coaxially in respect of the liquid feed tube, of which channel the inside diameter is 1 to 1.6 times the inside diameter of the outflow opening of the liquid feed tube and 2.5 to 10 times the curvature radius of the rounded area. To prevent erosion due to fluctuations in the process or to small changes in the design of the sprayer the invention is characterized in that the outflow channel (31), seen into the direction of flow, is conically narrowed.

    Abstract: The invention relates to a process for the removal of CO2 from acid gas by cryogenic distillation performed in two steps. The feed mixture is first distilled at high pressure (at least 45 bar) in a first distillation column. The top product or a part thereof is then, after heating, subjected to a second distillation step at a lower pressure (lower than 45 bar). The top product of the second distillation step is methane of high purity (more than 99 mol.%). The bottom product of the second distillation step is recycled back to the first distillation column. The method according to the invention allows complete separation of methane also at higher level of acidic components, is economical and does not result in solid CO2 build-up, which is a common problem in cryogenic distillation.

    Abstract: Disclosed is a reactor system for the production of polyester pre-condensate. The system comprises at least two reaction zones, operating at substantially different pressure. Reactants fed into the first zone are allowed to initially react and are then allowed to enter a second zone by means of pressure flow. In the second zone, a system of concentric spacers is present so as to ensure a sufficient path length of the reaction mixture to form a pre-condensate, as well as in internal heat exchanger. The pre-condensate is allowed to flow to a next (polymerization) stage by means of gravity flow on account of a standpipe present in the second reaction zone. Said standpipe has an inlet above the internal heating system in the second reaction zone.
