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...

Individual meter-in and meter-out proportional control of hydraulic cylinders allow more flexible strategies how to handle a payload while optimising certain aspects of the motion. An optimal control approach based on the Hamiltonian is used to plan a motion path for a separate meter-in and separate meter-out system. One goal is to avoid oscillations at the end of the motion in the sense of act...
