Question: Is a spare unit required for the forced recirculation reboiler pump?
Thread Content
As the title suggests, should a backup be provided for the pump of the forced recirculation reboiler? There’s no company PID either; is the load actual? Thank you to all the seniors!
Generally, the fluids used in forced-circulation reboilers are quite sensitive; therefore, pumps are employed to facilitate the heat exchange process. If a pump fails and there is no backup pump, how can forced circulation take place?
I personally think that such equipment should be used, but it’s the company’s management that decides otherwise. After all, the company has never implemented mandatory heat cycling before, so I’m not sure what the actual practice in such projects is like
Well, let’s follow the manager’s advice and have them sign for confirmation!
Movable equipment usually requires spares; don’t lose the big picture over small matters
Taking the site conditions into account, the reboiler with forced circulation that we install on-site uses a pump; however, this pump is too large – it’s a 300-cubic-foot submersible pump, and it’s not convenient to install it on the equipment. A spare pump is provided for maintenance purposes, so when the pump fails, the system can be stopped and the pump replaced
It should ideally be a spare unit, but since the circulation pump has a high flow rate and the cost of installing such a pump for the equipment is high, it’s possible that, in order to save on costs, no pump was installed for the equipment
It is generally not used as a standby unit; this is a hot standby pump. During the forced circulation process, there is no flow of material in the pump pipelines, which can lead to material precipitation and pipeline blockages. In the forced circulation systems for the engineering projects we work on, a pump is usually kept in the warehouse; when a failure occurs and the system stops, another pump is used as a replacement.
It seems my understanding needs further improvement. It now appears that for processes that are not continuous, it may not be necessary to have a backup pump, whereas for processes with high requirements for continuity, a backup pump must be installed to ensure the long-term operation of the system! :victory: Thank you all for answering my questions!
