Case Study Filtering Soda Ash using GORE Filter Bags

Consistent 1.2" H2O differential pressure has been maintained since installation of GORE membrane filter bags despite a 9" H2O excursion due to pulse-system failure. There has been no noticeable dust on the clean side of the tube sheet since installation. The first set of bags lasted three years.

Case Study Styrene Acrylinitrile Resin Rotary Dryer Filtering using GORE Filter Bags

Secondary after-filter blinding was eliminated. GORE membrane filter bags were cost justified in less than one month. Bag life was expected to approach two years. Customer quickly converted all SAN and ABS dryer systems to GORE membrane filter bags. Customer increased profits substantially in these areas.

Case Study PVC Spray Dryer Dustex Reverse Air Collector Filtering using GORE Filter Bags

Airflow increased by 10%. Production rated increased. Lower operating DP 1-2". Improved cake release eliminated product discoloration and product contamination. Bags attained 5+ years of service.

Case Study PVC - Paste Resins Conveying Line Collector using GORE Filter Bags

Lower operating DP (5"-7" DP) improved cake release, allowing increased airflow through collector. Bleed-through stopped, allowing capture of product. First set of bags lasted more than five years.

Case Study Toner Dust Jet Mill Collector Filtering using GORE Filter Bags

Results showed no visible emissions, excellent and consistent product yield, and secondary filter blinding significantly reduced. No bag failures since installation.

Case Study Carbon Black Dryer Exhaust Collector Filtering using GORE Filter Bags

Solution involved installing GORE Fabric Filter Bags. Results were sixty months of continuous, problem-free service, with excellent pressure differential.

Case Study: Filtering Grindings of Titanium Dioxide using GORE Filter Bags

Bag life is now between 9 and 18 months, as opposed to the previous 2-4 months. Energy savings due to low DP is about $2,000/year. Emissions are virtually non-detectable with 0% opacity. Improved product recovery provided over $10,000/year of additional salable products. Less downtime and improved airflow equated to a production increase of over 10%.

Case Study: Filtering Milled Calcium Carbonate Coated with Stearic Acid using GORE Filter Bags

High production levels and low pressure drop. Increased mill efficiency yielded considerable energy savings by producing a set tonnage in a much shorter period. The excellent cake-release characteristics enabled the collector to be operated continuously for 12 months at a maximum pressure drop of 5" w.g. The emission problem was eliminated.

Case Study Sodium Silicate Spray Dryer Filtering using GORE Filter Bags

Production goals met and exceeded without enlarging the baghouse. The bags have performed consistently well for the past 12 years, with scheduled changeouts every 24 months (although bag life has reached 30 months).

Case Study: Aluminum Oxide Catalyst Flash Dryer Filtering using GORE Filter Bags

The filter bags provided over 12 months of less than 6" DP service and allowed continuous production. At the design rate of 2,080 lb/hr failure occurred because of wear at the snap band cuff due to cage movement.
