    Abstract: A tubular reactor for thermally cracking fluorohydrocarbons has a burner system (1) with feed lines (3, 4, 6, 7) for a mixture of fluorohydrocarbon and fuel gas and for flushing gas and oxygen or air provided at one end of the tubular reactor. This burner system delimits the end face of a combustion chamber (2) which, near the burner system, is provided with an ignition branch (9) and devices (10, 11, 12, 13, and 14) for feeding and distributing a liquid. The combustion chamber is adjoined by an absorber of cylindrical blocks (21) with bores (22) parallel to the reactor axis for a liquid product stream and a gas discharged from the combustion chamber. The bores lead into a downstream annular chamber (28) which is provided with a branch (29) for discharging gas and liquid. The other end of the reactor has a pressure relief orifice (33) which is connected via a duct (32) to the combustion chamber (2).

    Abstract: The process relates to the production of a liquid absorbate from a liquid F and a readily soluble gaseous substance A. In this process, beginning with the liquid F and a gaseous mixture of A and a gaseous substance B sparingly soluble in F, this mixture, in a first reaction vessel, is brought into intimate contact with the liquid F, the undissolved portions of gaseous substance B are conducted away and the resulting liquid phase of F and A and small portions of B is expanded in a second reaction vessel. The thus released portions of B (and possibly A) are withdrawn as a gas phase. A liquid absorbate is obtained composed of F and A, which is essentially free of B. The gaseous mixture used is at a pressure of above 1 bar and the resulting liquid phase composed of F, A and small portions of B is expanded in an evacuated vessel. The vacuum is generated by a gas jet pump which is driven by the pressurised gaseous mixture of A and B. The gaseous mixture exiting the pump is brought into intimate contact with the liquid F. Alternatively, the vacuum is generated by a liquid jet pump which is driven by the pressurised liquid F. In this case, the liquid which exits the pump is brought into intimate contact with the gaseous mixture of B and, possibly, A.
