Can a frequency converter be installed on a restructured pre-hydrogenation compressor?
Thread Content
The pre-hydrogenation compressor is a reciprocating compressor with a power of 355 KW; it operates at 16 poles, with a current of 29 A, and its rated current is 36 A
For the lubricating oil pump, do you use a shaft-mounted pump or a separate screw pump? In the case of a shaft-mounted pump equipped with variable frequency drive, the motor speed can affect the lubrication effect. Additionally, in a hydrotreating unit, adjusting the variable frequency drive has an impact on the outlet pressures on both the hydrogen circulation side and the hydrogen supply side.
355kw with an inverter should work fine! However, the higher the power of the inverter, the more expensive it is, and the price increases very rapidly. The electrical engineering community might object, as it can cause interference in the power grid; moreover, variable frequency systems are more prone to failures than systems operating at fixed frequency. This power isn’t very high; it’s recommended to use the power frequency
The investment is high, the power output is not large, the energy-saving effect is not significant, and it is difficult to maintain stable export pressure. Reciprocating machines generally use stepless, backflow, or load-reduction control.
With such high power, installing variable frequency drives results in high costs; moreover, the adjustment process imposes stress on the power grid. There are many methods available for reciprocating machines to regulate flow rates
Considering adding a set of clearance adjustment mechanisms, a few hundred thousand isn’t too much.
