| 摘要 |
A method for the thermal cracking of hydrocarbons and other liquid/vapour processes, in which method the liquid feed is heated, and led to a reaction vessel (14) that is in an essentially horizontal position, in which, due to the large flow cross-sectional area, the flow velocity decreases and creates a delay to achieve the desired additional reactions, and in which method vapour is removed from the beginning of the reaction vessel (14). The intention of the invention is to create a more effective cracking process. In the system in accordance with the invention a vapour phase layer (20) is arranged on top of the liquid phase layer (19) over the greatest length of the reaction vessel (14), and that the liquid level is kept essentially constant by removing the vapour as required. The invention also concerns a corresponding soaking-cracker. |
