Frequency conversion issues of pumps in catalytic units
Thread Content
Frequency conversion is widely used in various devices, and catalytic devices are no exception. I have two questions. 1. Catalytic crude gasoline pumps generally do not have variable frequency functionality; is it possible to add such a feature, and is it safe to do so? Was it because considering high voltage in series with low voltage that it wasn’t added? Have any of you students added it? 2. Another factor is the reabsorber; generally, this pump does not have high power requirements (in our case, it’s 15 Kw), and moreover, the pressure in the absorption tower is relatively high. (For the same reason) Is it necessary to install variable frequency control on this pump? Whose device was added? Thank you so much!
According to the poster, the plant’s capacity is 200,000–600,000 tons per year; there is no need for additional equipment. For catalytic units equipped with variable frequency drives, an air-cooling system can be considered!
1. There’s a check valve – what’s there to worry about? 2. The payback period needs to be calculated for small pumps; generally speaking, they are not cost-effective. If there is still a benefit, then there is an issue with the pump selection you have made
