![]() ![]() A VFD (Figure 1) comprises a rectifier, which converts an alternating current into a direct current, followed by an inverter, which converts that direct current into a coarse version of an alternating current. The purpose of steam generation process in gas processing plants is to supply steam to all consumers and then recover condensate. ![]() Further economic evaluation beyond the approximate method must be performed, but because low- voltage VFDs require only a small incremental capital investment, their application cannot justify a very detailed evaluation. They also need to know about the interactions of pumps and hydraulics when the pumps run at variable speeds. To efficiently evaluate and apply VFDs, process engineers need to know certain elementary things about them. Normal project economics will now justify these VFDs. The prices of low- voltage variable frequency drives (VFDs) have declined substantially since they were introduced, while the cost of power has increased.
