Generic Approach of Using Dynamic Simulation for Industrial Emission Reduction under Abnormal Operations: Scenario Study of an Ethylene Plant Start-up

Abstract: Flare minimization under normal and abnormal operating conditions in large-scale industrial processes, especially for refineries and petrochemical plants, is a double-win practice, which simultaneously benefits industrial and environmental sustainability. Unfortunately, proactive and cost-effective flare minimization (PCFM) approaches under abnormal situations are still lacking. In this study, a PCFM approach for an ethylene plant is presented for its start-up operations. This approach employs rigorous steady-… Show more

“…Most of the reported research has investigated the unit performances based on rich industrial experience (see refs , , and ) and dynamic simulations of the plants (refs , , , and − ) so that different proposed start-up and shutdown strategies have been evaluated separately. Although the end-of-pipe FM approach is well-known in practice, most research has focused on the flare source reduction approach.…”

“…Dinh et al 180 proposed a dynamic simulation based proactive and cost-effective FM (PCFM) approach via downstream recycling methods for an ethylene plant's startup operation. They showed that the CGC start-up is the most critical operation and results in the largest amount of flare gas during the start-up.…”

“…As mentioned earlier, the lack of flaring incidents and flare management practices in the literature is an obstacle. 40 Hence, the industrial support to this work provided an opportunity to develop this integrated Data approach and it allowed for the generation of potential alternatives to flare management The i-Data approach developed for ASM is presented in Figure 3. The methodology consists of three major levels: data mining/acquisition, data analysis, and data utilization.…”

“…The bottom product is sent to the final column, C2 splitter, where the main product, ethylene, is separated and the rest of components are circulated back to the upstream and combined with the feedstock. 17,39,40 The ethylene plant is a front-end based technology, where the deethanizer unit leads the separation section, and its overhead product is fed to the acetylene hydrogenation unit. 900,000 tons of high grade ethylene per annum is produced.…”
