Isobaric energy recovery

The flow scheme for a typical isobaric energy recovery system is quite different from Pelton wheels or turbochargers and is shown in Figure 4.9. The isobaric energy recovery device is not connected to the high-pressure pump/motor assembly. Additionally, the...

Isobaric energy recovery systems allow a small portion of the concentrate stream to mix with the raw seawater as part of the process. This volume of bypass water is necessary to lubricate the moving parts. This leakage results in a slight increase in the TDS of the seawater exposed to the membranes and must be included in the SWRO system design...

From investigations reported in Chapter 6.6, it is obvious that the production-costs will mainly be dominated by the overall energy consumption, which will depend on the solvent flow-rate, extraction-, and separation conditions, and the process design features such as the isobaric- or non-isobaric, single- or cascade-mode working, CO2 recovery, the individual execution of particular plant components, and the degree of automation.
