Demo unit operation processing

To date, the benefits of the operational improvements have been verified and the improved activity of the second-generation catalyst has been confirmed, along with stability and full activity recovery over multiple HTRs. Representative performance data from the current demo unit operation processing refinery C4 olefins is presented in Figures 12.17 to 12.19 - for alkylate RON, RVP and C5 + yield, respectively. This data, based on automated sampling from the on-line analytical system, show both the high product quality achieved and the stability of the cyclic process over time. 

Construction of an AlkyClean process demonstration unit at Fortum s facilities in Porvoo, Finland, was completed in 2002. Figure 12.14 shows the process flow schematic of the demo unit, which contains all of the key elements of our proposed commercial design. Three reactors are included - two under cyclic operation (i.e., alternating between alkylation and mild regeneration) allowfor continuous production... 

The demo unit successfully operated to fully verify the process s improved performance under targeted commercial design basis conditions. Further, it allowed for parametric optimization and confirmation of bench-scale unit correspondence, and provided necessary support for our correlation and modeling effort. Based on all the positive progress to date, this demo unit campaign was successfully completed after three months. 

ES-1 Summary Evaluation of the Matnrity of Demo II Unit Operations and Processes, 3... 

General Recommendation DII 2. Before the AEA technology proceeds to the EDS phase, extensive testing should be performed on the SILVER IF process, including all the new unit operations that are being proposed to address the shortcomings identified in Demo II results. 

General Findii DII 2. The AEA technology package is a very complex, immature chemical processing system. Several new unit operations required to address problems revealed in the Demo n tests will significantly increase the complexity of an integrated processing system and extend the time required for its development.
