Product catalog summary
Introduction
Mott Corporation offers advanced filtration solutions for catalyst recovery using their HyPulse LS Series filters. These filters utilize sintered porous metal tubes, providing superior filtration compared to traditional methods like leaf filters, bag filters, or plate and frame filters. The HyPulse filters are designed to reduce operator exposure and disposal costs while enhancing catalyst recovery efficiency.

HyPulse Filter Configurations
  • HyPulse LSI: Ideal for high solids batch or continuous operations, maximizing filtrate recovery with an inside-out flow path.
  • HyPulse LSM: Suitable for high specific gravity solids, such as RANEY® nickel, and can be configured for continuous product recovery.
  • HyPulse LSP: Best for low-solids polishing applications with an outside-in configuration.
  • HyPulse LSX: Used for fine or attrited catalysts, employing crossflow microfiltration.

Advantages of HyPulse LSI Filters
  • Provides exceptional filtrate quality with less than 1 ppm particulate without needing a precoat or polishing filter.
  • Recovers 95-100% of filtrate and 100% of catalyst, minimizing loss and maximizing efficiency.
  • Operates as a closed system, reducing operator exposure and handling of hazardous materials.
  • Requires minimal downtime and maintenance, with no moving parts and fully automated capabilities.
  • Offers a wide range of materials for filter elements, ensuring long product life and compatibility with various processes.

HyPulse LSI and LSM Applications
HyPulse LSI and LSM filters are used across industries, including food additives and chemical manufacturing. For example, a U.S. food additive manufacturer uses HyPulse LSI to recover palladium on carbon, while a chemical manufacturer uses HyPulse LSM for RANEY nickel removal.

HyPulse LSP and LSX Filters
The HyPulse LSP is used for polishing applications with trace solids, while the LSX is recommended for systems where permeable cake formation is challenging. The LSX employs high-velocity crossflow to maintain filter surface cleanliness.

Laboratory and Design Capabilities
Mott Corporation offers comprehensive laboratory evaluations to support filter design, including feedstock profiling, filtration feasibility, and material compatibility. Portable HyPulse filter systems are available for on-site testing and scale-up assistance.

Company Overview
Established in 1959, Mott Corporation is ISO 9001 certified and operates from facilities in Farmington, CT. They provide engineering, sales, and manufacturing services globally, offering both stock solutions and customized designs.

Catalyst Recovery Filters-2

1082 catalyst recovery brochure Maximizing catalyst retention. Introduction. Process operations involving catalysts have traditionally used leaf filters for catalyst recovery, and either bag filters or plate and frame filters for catalyst removal. Modern filter technology, utilizing sintered porous metal tubes, provides superior filtration in both applications, and porous metal is now being specified in new construction and in the retrofit of existing systems. In addition to offering superior filtration, these porous metal filters reduce operator exposure to process materials, and reduce or eliminate...

1082 catalyst recovery brochure Advantages of HyPulse LSI filters in catalyst filtration. Utilities. • A minimal amount of downtime and maintenance is required for operation. “Permanent” porous metal filter elements eliminate the need for frequent cartridge or bag replacement and disposal. Mott Corporation recommends the HyPulse LSI Filter configuration for most catalyst applications. The following is a brief description of distinct LSI benefits. • Filters have no moving parts. Superior Filtrate Quality. • Exceptional filtrate quality, with less than 1 ppm particulate. Mott porous metal filter...

1082 catalyst recovery brochure Mott HyPulse LSI catalyst filtration process. Removal of catalyst from the reactor system. A simplified installation schematic for the HyPulse LSI in a typical catalyst application is shown below. Many reactor systems require that a portion of the catalyst be replaced for each cycle. This illustration shows a typical HyPulse LSI catalyst filtration application. A general description of a typical operation is as follows: Wet Cake Discharge – Solids Purge Filter. Slurry Backwash Recycle – Primary Catalyst Filter. 1. Valve (1) is opened. The reactor is pressurized...

1082 catalyst recovery brochure HyPulse LSM filters design versatility. Mott’s unique HyPulse LSM design incorporates all of the features available in the LSI design, with the added capability of introducing feed to the top of the filter. This feature eliminates the potential for classification of high-density solids which can occur in an upflow mode. As shown below, the patented LSM design utilizes “double openended” filter elements which allows for incorporation as crossflow filters into recirculating reactor loop systems. Inside-out Filtration Outside-in Filtration Inside-out filtration used...

Catalyst Recovery Filters-6

1082 catalyst recovery brochure HyPulse LSI and LSM filters are used in catalyst removal and recovery applications in multiple industries ranging from food and ingredient manufacturers to petroleum refineries. Two recent applications are described below. LSI application. A U.S. manufacturer of proprietary food additives needed to recover palladium on carbon following each hydrogenation batch. It was important to design the filter based on solids-holding capacity in order to process a complete batch prior to backwashing. The HyPulse LSI provided this customer with high product recovery in the...

Catalyst Recovery Filters-7

1082 catalyst recovery brochure Laboratory and design capabilities. Mott can apply its conventional outside-inside flow configuration (HyPulse LSP) in cases where only trace quantities of solids are present (typically < 100 ppm). In these “polishing” applications, there is little concern for significant development of filter cake on the outer diameter of the elements, and element spacing is not as critical as is the case for most catalyst recovery operations. Applied to polishing applications, the HyPulse LSP is designed with an economic, close-packed, removable filter element bundle. Backwash...
