Product Description Item DescriptionDownflow reactor internals Down Flow reactors exhibit a distinctive feature characterized by a downward flow, extending from the top to the bottom of the reactor, fostering chemical reactions between reagent fluids and the catalyst. In a standard two-bed Down Flow reactor setup, the reagent fluid undergoes distribution, facilitated by an inlet diffuser, across the foundational distributor tray. This tray plays a crucial role in ensuring the uniform dispersion of liquid over the catalyst bed beneath, upheld by the catalyst support grid. Advancing through the reactor, the quench zone comes into play, where gas injection cools the reagent fluid, subsequently directing it into a mixing chamber. Here, another distributor tray efficiently allocates the liquid over the subsequent catalyst bed. Positioned at the reactor's bottom, the outlet collector supports the lower catalyst bed, facilitating the outward conveyance of the reacted fluid.DetailsDownflow reactor internals for the hydrocracking processWithin the hydrocracking unit, a series of down flow hydrocracking reactors form the core of the operation. The ingenious design of these reactors, coupled with the strategic placement of internals such as 'distributor and redistributor trays,' 'mixing trays,' 'catalyst support grids,' and 'outlet collectors,' orchestrates a seamless downward flow of fluids within the reactor. This design optimally facilitates reactions essential for the dealkylation of aromatic rings, the opening of naphthenic rings, and the precise breaking of paraffin bonds. Saiptech boasts extensive expertise in the mechanical design and production of downflow reactor internals specifically tailored for the hydrocracking process. This intricate procedure serves the dual purpose of eliminating contaminants (such as nitrogen, sulfur, and metals) and transforming low-value gas oils into high-quality products like naphtha, middle distillates, and pristine lubricant base stocks. Operating at the heart of this hydrocracking endeavor, the hydrocracking unit seamlessly integrates with the vacuum distillation unit to receive its feedstock. The initial hydrogenation phase diligently rids the feedstock of sulfur, nitrogen, and metals. Subsequently, the process delves into the dealkylation of aromatic rings, the opening of naphthenic rings, and the strategic breakage of paraffin chains. The fruits of these efforts manifest in the form of valuable light ends (marketed as LPG), naphtha (either sold as petrol or directed to the catalytic reforming unit), and premium diesel. Executed within one or more hydrocracking reactors equipped with a fixed bed catalyst, the dealkylation phase epitomizes Saiptech's commitment to precision and efficiency in the realm of hydrocracking technology. Distinctive characteristics of the Saiptech down flow reactor internals for the hydrotreating process are:Internal production of all the filtering elements used in making the internals (wire cloth weaving, punching and production of wedge wire screens)Internal production of all the internals, from the 'inlet' to the 'outlet collector'.Many years of experience in mechanical design and construction of internalsAvailability of dedicated teams highly experienced in project management
