By dividing the compression work into various stages it results in a lower power requirment. This is visible in the p--v diagram.<br />
Fig. 2 shows the power requirement with a theoretical 1 stage compression to 200 bar.<br />

By dividing the compression work it not only saves energy, but it also increases the operating safety due to a lower thermical load.<br />
