Questions regarding the P&ID of the distillation column with a thermal siphon reboiler
Thread Content
Dear experts, I have a question: What does ST stand for? (The symbol in the picture was mistakenly typed as SI.) Does T refer to a steam trap? Does LICA maintain the stability of the liquid level in the distillation column by adjusting the amount of steam supplied to the vertical thermosyphonic reboiler, thereby controlling the amount of vaporization of the liquid within that reboiler and influencing the amount of liquid that flows into the reboiler from the bottom of the column? Thank you!

According to your drawing method, writing ST inside a circle indicates that ST is a gauge; and based on gauge symbols, ST represents a temperature control switch, while T refers to TRAP, which is a steam trap. In other words, a steam trap with temperature regulation? Haven’t seen it before. Generally, the drain valves in siphon heat exchangers do not require adjustment.
