Specialty Chemical Manufacturing Solutions

Mott porous metal products are used in multiple chemical processing operations and pharmaceutical ingredient manufacturers can achieve the best filtrate quality and catalyst/activated carbon removal by using Mott sub-micron filtration technology.

Mott process filters can withstand the most corrosive process conditions found in agrochemical manufacturing. Various alloys, such as Monel, Inconel, and Hastelloy are available to achieve chemical compatibility with various feed streams. These elements can last years in corrosive environments through proper maintenance and cleaning procedures.

Mott’s liquid filter technologies are specifically designed to capture 99+% of catalyst — either for recycling or reclamation while achieving excellent filtrate quality. The Mott HyPulse® LSI can be designed for a variety of clean-in-place backwashes, ranging from discharge of an approximate 15 wt. % slurry to an approximate 50 wt.% wet cake.

Mott has been the leader in both crude terephthalic acid (CTA) and purified terephthalic acid (PTA) for decades using both HyPulse® LSI and LSM filter technologies.  Mott liquid filters are easily configurable to handle multiple wash and purge steps necessary in CTA and PTA processes to ensure product quality.  Our filters reduce caustic acid consumption in the CRU, reduce organic loads to wastewater treatment, and can recover up to 2 wt.% solids from CTA or PTA applications.

Mott has helped polyol and resins manufacturers achieve peak operational efficiency for decades. Whether it’s removal of residual catalyst, salts, solidified or burnt product from the production stream, Mott HyPulse filters withstand high process temperatures (up to 1700°F with Hastelloy® X), keeping fluid viscosity low and eliminating the need for heat exchangers to cool prior to filtration.
