Questions about sulfur recovery units?
Thread Content
In the CLAUS reaction, the condensation cooler is controlled using a liquid level mechanism; why is there also a liquid level indicator at the front end? ? ? Is it because the difference in liquid levels before and after is very large? ? ?
Basically, it prevents the liquid level at the front end from dropping too low, which could affect the cooling effect of condensation.
It is mainly to maintain a certain volume of cooling water in the condenser to ensure effective condensation
To ensure that the liquid sulfur in the process gas condenses and flows out, sulfur recovery unit condensers are normally designed with a slope of 1-3%, as a result of which the elevations at the front and rear ends of the condenser differ; therefore, level gauges must be installed at both ends.
I agree with the opinion from the fourth floor; this is mainly due to the special viscosity-temperature properties of liquid sulfur. The cooler and the pipelines for liquid sulfur must have a slope of 1% to 3%. Additionally, since the liquid sulfur cooler is used for level control, in order to improve the accuracy of this control, level gauges need to be installed at both the front and the back!
It is mainly for safety reasons. Typical steam generators (drum boilers) are equipped with two liquid level indicators, commonly referred to as \"dual liquid level indication,\" which is mainly intended to prevent false readings from the instruments from causing the steam generator (drum boiler) to run dry.
The liquid level in the cooler remains basically constant. Two levels are for safety. Important: The coolant level does not need to be adjusted
Thank you, I’ve learned it*:victory:
When installing the individual units of a sulfur production plant, they are generally given a tilt of 1%. Installing level gauges at both the front and back facilitates accurate readings; of course, there are also cases where level gauges are installed only on one side. However, it is essential to ensure that the installation levels of the level gauges on each unit are at the same height, so that the readings remain consistent
It is mainly for safety reasons. It is to prevent incorrect readings on the instruments; there is no need for control of the liquid level at the front end, as the goal is to condense the liquid flow within the reactor
