this paper tries to determine an optimum condition for the flotation operation of the alborz-sharghi coal washing plant. for this purpose, a series of comprehensive experiments have been conducted on representative samples from feed of the flotation system of the plant. four operational variables such as the collector dosage (fuel oil), the frother dosages (mibc), the pulp density percent and t...

This research proposes the combination of a dual-loop non-organic Rankine cycle (DNORC) with an internal combustion engine to increase the output power of the recovery system by focusing on the increase in the energy input and system efficiency. In doing so, it investigates the strategy of increasing the mean effective temperature of heat addition in the high-temperature Rankine cycle (HTRC) (t...

conceptual design of a waste heat recovery cycle is carried out in attempt to enhance the thermal efficiency of a steam power plant. in the recovery system, super-critical an co2 is employed as the working fluid operating in a brayton cycle. low grade heat rejected by the flue gases through the stack is used as the primary heat source, while a secondary heat exchanger utilizes the hot gases lea...

in this research, feasibility study of integrating thermal desalination unit with gas turbine (gt) has been investigated using retrofit and grass root design techniques  for lavan island oil refinery which is located in persian gulf. according to computed parameters on developed code for the power generation unit no.1 using ees (engineering equation solver) software, thermal efficiency of the g...

in this paper, a new systematic design methodology has been developed for thes imultaneous energy and water minimization in multiple-contaminant systems that also feature maximum re-use of water. in addition to allowing re-use of water in multiple-contaminant systems, issues about heat losses and flowrate changes inside unit operations have also been incorporated in this new design method. to i...

water and energy are key commodities utilized in the process industries.water minimization and energy minimization have been studied separately. in this paper, a new systematic design methodology has been developed for the simultaneous management of energy and water systems that also feature maximum re-use of water. in addition to allowing re-use of water, issues about heat losses inside unit o...
