COST OPTIMUM HEAT EXCHANGER NETWORKS-l. MINIMUM ENERGY AND CAPITAL USING SIMPLE MODELS FOR CAPITAL COST
An important feature of heat exchanger network design is the energy-capital tradeoff. This tradeoff has been regarded as complex due to the number of structural network alternatives usually available, each being subject to continuous optimization. Current procedures tend to first identify minimum energy networks. The total cost (capital and energy) can then be improved by evolution and continuo...
متن کاملArea Energy and Throughput Targeting in Debottlenecking of Heat Exchanger Networks with Decomposition Approach
For energy saving retrofit projects, its economics are usually evaluated in terms of capital investment and payback time. The capital investment is in direct relation to the total heat recovery area of the network and the payback time factor is base on both the area and the energy savings. The debottlenecking is an increased throughput, which can be profitable in economic sense. The combination...
متن کاملLEBRP - A Lightweight and Energy Balancing Routing Protocol for Energy-Constrained Wireless Ad Hoc Networks
A wireless ad hoc network typically refers to any set of wireless networks where all devices have equal status on a network and are free to associate with any other wireless ad hoc network devices in their range. As the nature of these networks, they commonly do not have external power supplies, and each node has a limited internal power source. In this paper, we put forward a new routing proto...
متن کاملSynthesis of Heat Exchanger Networks for Controllability
Heat exchanger networks are widely employed in the chemical processing industries to recover energy, resulting in reduced operating costs. Several methodologies can be found in the literature for the design of heat exchanger networks. Typical criteria are maximum energy recovery and minimum heat transfer area. However, the heat integration of process streams can lead to process structures that ...
