2. Choosing the right recovery technology for your processes

The selection criteria for recuperator technologies are many and varied. It is important to identify :

• firstly, the states of the fluids likely to pass through the recuperators; three possibilities are offered to the engineer (gas-to-gas recuperator, liquid-to-liquid recuperator, gas-to-liquid recuperator); the figures "Atmospheric-pressure gas/gas recuperators", "Liquid-to-liquid or high-pressure gas/gas recuperators" and "Atmospheric-pressure gas/liquid recuperators" illustrate the technologies available for each configuration;

• secondly, nominal and maximum operating pressures and temperatures;

• thirdly, the expected thermal output ;

• fourthly, their corrosion and fouling resistance, and their suitability for cleaning and technical inspection;...
