Waste reduction heat exchangers

But via, for instance, high-heat exchange reactors (HEX reactors) that allow a much shorter reaction time and at the optimal temperature, process intensification can also reduce the formation of by-products considerably. A by-product reduction by a factor of 4 is achieved via a HEX reactor (46). This means a considerable reduction in feedstock cost and waste handling. 

The use of exhaust steam from turbines driving the compressor to heat the feed would make a very significant reduction in the size of the auxiliary heat exchangers (those exchanging heat between feed, product water, and waste brine) and reduce the cost of water by about 7 cents per 1000 gallons. The cost of product from a 10,000,000-gallon-per-day plant was estimated to be in the range of... 

Expand partnerships and information exchange and facilitate collaborative research and development for beneficial uses of nuclear energy — including evolutionary and innovative technological developments for improved competitiveness, safety, proliferation resistance and waste reduction — particularly for developing countries in the areas of small and medium size reactors and non-electricity applications such as desalination, heat production and hydrogen production. ... 

Several authors have shown the industrial profit in the development of chemical engineering equipment based on the integration of different functions in a single device (Taylor et al., 2000 Stankiewicz et al, 2000). Multifunctional reactors are processes that combine reaction with other operations like heat exchange or separation in order to enhance chemical conversion. Reactive distillation is certainly one of the most significant example. It presents several benefits (such as reduction of energy consumption, overcome of the limitation of the thermodynamic chemical equilibrium, limitation of side reactions, decrease of waste production) and it is applied in various...
