N2  - Shell has long been a leader in third stage separator (TSS) technology. At the core of Shell’s TSS performance are its swirl tubes, with an industry leading d50 cut point, that allow Shell’s TSS design to easily meet emissions values of 50 mg/Nm3 for particulate matter (PM) in the flue gas with typical dust loads from the regenerator, in addition to protecting the expander. Data from a number of TSS operations has shown that even at higher than expected regenerator outlet dust loads, the Shell TSS is able to minimize the PM emissions in the flue gas out of the stack. As a result, Shell’s TSS design is able to be implemented in situations where only electrostatic precipitators (ESP) used to be viable. In addition, Shell has a swirl tube fourth stage separator (FSS) offering that distinctly outperforms an FSS cyclone and gets close to an FSS filter application. On top of this, Shell has catalyst cooling technology in the underflow line that no other TSS licensor offers. This underflow cooling technology reduces the catalyst temperature to the FSS by several hundred degrees Fahrenheit, leading to more efficient FSS separation efficiency. This paper will provide examples of these Shell PM reduction technologies in operation along with the performance benefits seen
