Knight Material Technologies can provide sulfuric acid manufacturers assistance in solving mass transfer and operational problems in the gas cleaning, drying and absorption towers. We have helped customers increase their tower’s capacity and improve gas-liquid distribution while providing longer service life with lower pressure drop.
From simple tower packing and internal change-outs to complex tower upgrades with high-efficiency tower packing to complete new design and construction, we offer a complete turnkey package from a single system supplier.

Liquid Distributors deliver continuous and precise distribution of acid for optimum absorption efficiency, minimum mist generation and maximum service life of downstream equipment in sulfuric acid plants.
Corrosion resistant alloy Liquid Distributors reduce installation, maintenance, and lifecycle costs. They have significantly lower lifecycle costs than conventional designs in cast iron.
FLEXISADDLE® Ceramic Random Packing
This is the most widely used random, mass transfer media on the market today. Its unique form provides a highly effective surface area and a low resistance to the air flow for mass and heat transfer optimization. Due to its high quality, it provides economic value for applications worldwide:
Flexeramic® Ceramic Structured Packing
Structured media with geometrically arranged corrugated sheets offering superior operation over saddle random media. Our proprietary media designs provide greater resistance to fouling than random or monolithic media:
Cross Partition Rings Used with Random Packing
Rings with a cross-shaped septum have a high resistance to acids (>99.6%), virtually no water absorption (<0.5%) and a resistance to at least 10 heat cycles. Ceramic rings have high throughput and low pressure drop. This reduces the energy costs for pushing a gas mixture through the column and increasing the tower efficiency.
Knight-Ware® KPS Self-Supporting Dome and Packing Support
Our Self-Supporting Domes provide more than 60% open area before the tower packing is installed, offering a significantly increased open area over standard grid bar designs and providing:
Duro® Acid Brick and Chemical-Resistant Mortar
Our bricks maintain corrosion resistance in high-temperature and strong acid concentration environments, conforming to ASTM 279 specifications. DURO® brick is manufactured in standard and custom shapes and sizes. Our proprietary mortars are formulated to bond our brick lining systems to meet most corrosion requirements. We offer a variety of mortar types and formulations to service most strong acid and high temperature process environments.
PTFE (Polytetrafluoroethylene) Duply Liner
PYROFLEX® Duply lining consists of PYROFLEX® membrane with a PTFE overlay. The PTFE overlay is installed on top of the PYROFLEX® to provide an additional layer of protection and acid resistance.
Pyroflex® Acid-Resistant Membrane
PYROFLEX® Acid-Resistant Membrane is a flexible, uniformly thick sheet membrane used as an acid-resistant barrier between acid-resistant brick and corrosion prone carbon steel. PYROFLEX® is fused directly to a properly cleaned and primed surface without the use of an adhesive to provide a continuous, uniform lining with no joints. It also acts as an expansion-absorbing material between the masonry and the steel or concrete shell.
In direct contact with acid, the Carbon Steel Shell, that constitutes the main structure of the tower, is not resistant to acid attack, progressively deteriorates and therefore requires protection.
