Abstract: The invention relates to a process for separating off solid particles, in particular coke particles, from a water phase by means of gravity in a plant for generating hydrocarbons by cracking a hydrocarbonaceous feed, and also to a device for carrying out the process. In contrast to the prior art, the water phase is taken off predominantly from a point above the column bottom B via the outlet A. The first gravity separator 2 which is constructed as a multistage settling tank 2 is situated not beneath, but next to, the scrubbing water column 1. The bottom phase of the scrubbing water column 1 already acts as a part of the first gravity separator 2. Thus, via the outlet 5 in the column bottom B, a heavy water phase which is loaded with coke particles is already taken off and passed into the second gravity separator 3. This heavy water phase is further treated, together with the heavy water phase which is loaded with coke particles from the recesses 6 of the multistage settling tank 2.

Abstract: A method for monitoring a frequency signal provided within a unit is disclosed. The method comprises a step of receiving one or more binary signal levels of a cycle signal (CLK) or a control signal (CS) from a communication interface (CLK, CS, MOSI, MISO), wherein the communication interface (CLK, CS, MOSI, MISO) is designed to transfer information according to a communication protocol. The method further comprises a step of providing the frequency signal in the unit and comparing the frequency signal to a temporal sequence of signal levels of the cycle signal (CLK) received by the communication interface (CLK, CS, MOSI, MISO) in order to obtain a comparison result or controlling a counter by the control signal (CS) and the frequency signal in order to obtain a counter status.
