Is the hydrogen sulfide concentration tower required to be 7 meters above the ground level?

It must be due to considerations regarding safety and environmental protection

Could you elaborate on your thoughts?

It mainly achieves the goal of reducing power consumption by increasing the voltage difference, thereby raising the inlet pressures of P1, P2, and P3 and reducing their power consumption.

The inlet pressure of the pump increased, but the head also increased accordingly. As a substance, hydrogen sulfide may cause accidents due to excessively high local concentrations in the event of a leak at ground level, but it will be dispersed at higher altitudes or people will have enough time to react accordingly

It doesn’t make sense; no matter how high above the ground it is, leakage will still occur. Have I still not understood what you mean?

Personally, I feel that with a higher elevation from the ground, the pump is less prone to cavitation.

I thought I had explained this issue clearly, but it seems necessary to discuss it further. Firstly, it is true that increasing the inlet pressure as a means to prevent pump cavitation, as mentioned, but this is not the main reason why the hydrogen sulfide concentration tower is designed to be 7 meters above the ground level. You might want to check at what height the hydrogen sulfide concentration towers in your own company are located above the ground Has cavitation occurred? I’ve seen in several companies such as Xinneng Phoenix, Xinneng Energy, Inner Mongolia Jiutai Energy, and Inner Mongolia Donghua Energy that the hydrogen sulfide concentration towers are located on the ground or at a very low height above it. Don’t they worry about cavitation in the P1, P2, and P3 pumps during design? Nor has it been heard of any pump suffering from cavitation due to the low location of the hydrogen sulfide concentration tower. Furthermore, since the hydrogen sulfide concentration tower is designed to be 7 meters above the zero level, this results in a reduction of at least 10A in the current consumption of pumps P1, P2, and P3. This leads to a power savings of 380*10*3/1000 = 10.4 kWh per hour; over 24 hours, this amounts to 24*10.4 = 273.6 kWh per day. Assuming 330 days of operation per year, the annual power savings amount to 273.6*330 = 90288 kWh. The benefits are still considerable. Therefore, reducing power consumption is the main reason.

The suction lift is reduced, but the head is increased – will the motor use less energy? ? ?

It’s probably due to the allowable suction height; this is determined by the properties of the medium being pumped, otherwise cavitation is likely to occur
