“…The mass flow rate of the working fluid is considered to be constant and the heat transfer from the absorber pipe to the working fluid is convection only. Under the assumptions stated above and with the differential control volumes around the absorber pipe, the energy balances for the absorber pipe and the working fluid can be written as follows (Euh and Kim, 2013):…”

Salt removal from drainage water is becoming increasingly important for sustainable irrigated arid land agriculture where inadequate drainage infrastructure exists. Solar evaporation and concentration systems are currently in development in California for this purpose (Kim et al., 2007b). One technique under evaluation is an agricultural drainage water reduction system using a solar collector and a fire-tube boiler. This system can reduce a considerable amount of drainage water and leave residual salts at the bottom of the system. The remaining salts can be separated and recovered by pure salt products, such as NaCl, Na 2 SO 4. Fundamentally, salt quality, production cost, and facility cost will be main issues for developing purified agricultural salt products. The recovery and separation of the salts should be investigated further. A parabolic trough solar collector (PTC) is frequently employed for solar steam production (Kalogirou et al.,
