Terephthalic Acid Filters
Mott, a trusted name in filtration, has been at the forefront of purifying both crude terephthalic acid (CTA) and purified terephthalic acid (PTA) for decades, employing cutting-edge HyPulse® LSI and LSM technologies. Mott’s liquid filters, equipped with advanced terephthalic acid filters, can be easily tailored to accommodate multiple wash and purge steps crucial in the CTA and PTA processes, ensuring impeccable product quality. These innovative terephthalic acid filters from Mott not only reduce caustic acid consumption within the CRU but also minimize organic loads in wastewater treatment, while recovering up to 2 wt.% solids from CTA or PTA applications.
In scenarios where corrosion control is paramount, the Mott LSI serves as an intermediate filter, efficiently removing precipitated corrosion metals before downstream processing. The remarkable return on investment (ROI) for a Mott LSI in a CTA or PTA application averages just two years, making it a sound choice for those seeking enhanced efficiency and cost savings with top-notch terephthalic acid filters.

| Cleaning |
Mott Terephthalic Acid Filters are designed for clean-in-place performance, meaning filter elements can discharge cake build-up without having to open the filter for maintenance. Once a terminal pressure drop has been reached, the cleaning cycle automatically initiates to discharge cake build-up through gas-assisted pulse or through a backwash cycle. Particles will embed in the filter media over time, requiring the elements to be cleaned by a third-party company. Various cleaning techniques can be used to prolong life of the elements. For a recommendation of a cleaning company, please contact a Mott representative. It is recommended you keep a spare set of filter elements to continue operations while elements are being cleaned. |
The Mott Filter Design Process
- Filter Feasibility Testing – In our Customer Innovation Center, we will replicate, or very closely correlate, your process conditions to determine the appropriate media grade and material for your application, including terephthalic acid filters. We will provide you with a comprehensive, in-depth analysis to prove the feasibility of using porous metal, including terephthalic acid filters, in your process and furnish you with a comprehensive ROI justification.
- Pilot Testing – As an option, we can install a pilot unit with terephthalic acid filters in your facility enabling you to witness, first-hand, how our filters will perform in your process stream and under your actual operating temperatures and pressure conditions.
- Front-End Engineering Design – Our Front-End Engineering Design (FEED) process provides you with a complete process engineering package, including vessel drawings, a preliminary equipment layout drawing, piping and instrumentation diagram, process flow diagram, valve and instrument list, and a detailed process functional description, all designed to incorporate terephthalic acid filters.
- Fabrication – When it comes to fabricating your system with terephthalic acid filters, we can handle as much or as little as you need – from fabricating only the filter vessel, to providing a complete turnkey skid system.
- Operational Support – When your filtration system with terephthalic acid filters is complete, our professionals can provide equipment commissioning and startup services, training, ongoing technical support, and quality assurance testing for the life of your system.
Depending on your needs, Mott can provide just the filter elements, a vessel and elements with terephthalic acid filters, or provide you a full turnkey system with the vessel, frame, piping, instruments, and controls.
