In order to accommodate non-symmetric and/or non-uniform loadings, Emtrol also offers 3D modeling and analysis that is conducted in-house to ensure timely response to design changes.  3D modeling permits detailed design for unique loading conditions and depicts the effect of the non-symmetric loading.  Although primarily used for analysis of the primary membrane and bending stresses due to cyclone loadings and pressure, 3D FEA models can also incorporate the secondary thermal stresses produced by the thermal gradient in the plenum skirt. 

3D modeling can be ideally applied to our unique support design, the Emtrol Patented Beam Hanger Support System, when future expansion must be considered.  Our beam system is typically used in FCC regenerators and its unparalleled design accommodates incorporating "future" cyclone sets.  These sets can be installed in the vessel to increase throughput without any modification to the vessel itself.  The beam system is used to support the new cyclone loads and the only modification required to the system is at the connection of the last stage cyclone outlet tube to the plenum skirt.  Emtrol has used 3-D modeling to confirm that the plenum design can handle both the non-symmetric loading ("future" cyclones not installed) and the "future" symmetric loadings, thereby designing a support system with future throughput capacity.
