Could some expert please help explain what this means?
Analysis and configuration should be carried out in accordance with the process requirements; HSW stands for manual switching, which means that the operator manually switches to control the control valve based on which of the two liquid levels is higher. But if it is automatic switching, it should be changed to high selection HS.
Thank you. This is a reaction vessel; there are two level gauges at the bottom and in the middle of the vessel, and three control valves are used to regulate the discharge
There are many accidents involving reaction vessels, so the process is very important; one should not rely on guesswork – it’s necessary to consult the design team or relevant documents for confirmation. =========================== 【HaiChuan Safety Discussion】Compilation of reaction vessel accident cases and safety measures https://bbs.hcbbs.com/thread-3002321-1-1.html (Source: HuahaiChuanliu – HaiChuan Chemical Forum Website)
