Naphtha Steam Cracking (NSC) Unit Optimization: The Use of Robust On-line Analyzer Technology for the Real-time Optimization of Steam-cracking Furnace OperationInnovation in Analytical Techniques
Co-Author: Allan J. Rilling
Abstract: The main compositional measurement required for feed naphtha quality determination is PIONA (% of total paraffins, iso- araffins, olefins, naphthenes, and aromatics). This information is provided to a part of the APC system which acts as a complete furnace simulation and yield predictor. This will typically estimate, for a given severity, the total gas-make, ethylene/propylene yield, coking index, or similarly defined parameters. Depending on the particular setup, the furnace simulator and yield estimator may require input data as a simpler reduced data set (e.g., PIONA and key distillation.
parameters such as T05, T95), or it may require a full C-numberâ€“based breakdown of the entire hydrocarbon composition. Process FT-NIR analyzers are able to meet both of these requirements effectively. The exact choice of analyzer platform can be selected to achieve this in optimal fashion.
