Data acquisition and analysis of total sites under varying operational conditions

The procedure of data acquisition under uncertain operating conditions is presented when retrofitting existing plants and Total Sites (TSs). Heat Integration (HI) and TS Heat Integration (TSHI) are performed within larger-scale industrial plant. Several studies exist regarding performing HI and TSHI under fixed conditions, both for grassroots designs (minimum energy requirement designs) and for retrofits. They have been some studies published only, which have completely address how to perform internal plant HI and TSHI when the fluctuation of operational conditions are considered at the larger scales, such as within petrochemical plants. The data acquisition for HI and TSHI under varying operational conditions still needs more attention. Those two issues are tackled by the presented work.
