Unit anti-surge valve
Thread Content
Our unit is of the 1-to-2 type. At present, the anti-surge valves for both the air compressor and the booster are not fully closed, which results in high energy consumption. I would like to ask everyone: if my unit is operating normally, how can I increase its performance to the maximum level by fully closing the surge valves? What are the impacts of this on subsequent systems, and what requirements does it place on the unit?
Normally, according to the design, the drain valve should be fully closed; without considering other factors, increasing the production load of the device is sufficient to resolve the issue. Another approach is to stay as close as possible to the anti-surge region and reduce the amount of air drawn in, which should be the best adjustment strategy. Just be sure to pay special attention not to enter the surge zone.
The anti-surge zone serves to protect the unit; it is related to the location of the power source for the fractionation system, and can be adjusted via the inlet vanes in order to reduce air waste within the fractionation system.
If there is no surge issue with the booster, close the guide vanes. If it’s close to the surge zone, it’s better to reduce the pressure
If ITCC is used and both the anti-surge valve and the guide vanes are set to automatic mode, the anti-surge valve cannot be closed; this can only indicate that: 1. The air load and the product load have not been set correctly. 2. The design operating conditions of the air compressor are on the high side. Fully closing the anti-surge valve has no impact on subsequent loads, but closing it manually affects the entire system and the unit.
