Recent advancements in valve design and materials have led to substantial improvements in residue hydrocracking reactors (RHRs) operations. These innovations address key issues such as thermal shock, corrosion and the need for precise control in these critical processes. For example, thermal sleeves utilizing advanced materials and manufacturing techniques, like ceramic coatings and 3D printing, have emerged as effective solutions for protecting valves from rapid temperature fluctuations. These designs minimize heat transfer through conduction, convection and radiation, significantly extending valve lifespan and reducing maintenance requirements.
Gasket technology has also evolved to meet the demands of RHR environments. High-performance gaskets, including those employing noble metal plating, offer enhanced corrosion resistance, thermal stability and durability. These advancements ensure better sealing performance and reduced risk of leakage, which is crucial for both safety and efficiency in hydrocracking operations.
