Flexeramic structured packing
 Designed for acid applications, Flexeramic structured packing provides a lower pressure drop than most other random packings and trays on the market. Composed of corrugated ceramic sheets that are vertically aligned in the packed column, the elements eliminate any horizontal surfaces that may create resistance to fluid flow. This geometric construction reduces the channeling of both liquid and vapor, and provides for more effective contact of sulfuric acid and sulfur trioxide gas. This increased efficiency offers improvements in moisture removal from incoming air, which minimizes the opportunity for SO3 slip along the absorber wall. Substituting this packing in standard packed or tray columns can achieve a pressure drop decrease of up to 60% and improve efficiency by 2%, resulting in lower energy costs for most distillation and absorption operations.

Knight-Ware PV33P fireclay acid brick
The Knight-Ware PV33P fireclay acid brick is suitable for chemical processing industry vessels, such as chlorine drying towers and quench columns. Engineered to provide a low predictable swell in corrosive applications, it can withstand the thermal shock and spalling common in such equipment. The brick complies with ASTM C-279 Type 1 designation for chemical-resistant masonry, and is durable enough for the harshest corrosive and high-temperature environments. As part of an engineered lining system, the brick ensures maximum service life and reliability for pressure vessels. It is offered in a range of sizes and shapes, and is available for acid-resistant masonry construction for vessels and dished heads of various sizes.
