Design a single stage RO desalination system by calculating the permeate salinity, the brine salinity, the brine flow rate, and the membrane area. Analyze the following cases:

Data

Water permeability is 2.05xl0-6 m3/m2 s kPa

Salt permeability is 2.03x10-5 m3/m2 s

Feed salinity is 34,000 ppm

Feed flow rate: 2.5 kg/s

Permeate flow rate: 1 kg/s

Feed pressure: 6000 kPa

Reject pressure: 5800 kPa

Permeate pressure: 101 kPa

1. Rand water research committee consisting of 12 chemical engineers design a reverse-osmosis plant to recover 30 % of the seawater feed water as portable water. The permeate pressure used is five time less than the feed side pressure. The total spiral wound membrane surface area is 464000 m2 for a single stage crossflow. Calculate the salt passage and water permeance given the characteristic of the feed water, permeate and final brine as in table below. Flow rate Concentration Pressure...

Consider a single-stage refrigeration system operating between the pressure limits of 1.4 MPa and 160 kPa with refrigerant R134a as the working fluid. The refrigerant is a saturated liquid at the condenser exit and a saturated vapor at the compressor inlet. The isentropic efficiency for the compressor is 80 percent. If the mass flow rate of the refrigerant through the cycle is 0.11 kg/s determine (a) the rate of heat removal from the refrigerated space, and (b) the coefficient of...
