If you were looking for ACS Separation Products or AMISTCO Industries, you are in the right place. AMACS is the product of a merger between these two leading companies in the mass transfer market. This new website, now under the AMACS brand, replaces separate sites for ACS and AMISTCO. Our new customer site features product information in English and soon in Spanish. We also offer forms to receive quotes, request tracking on shipments and carried our Ask AMISTCO program over through Ask AMACS. Here you can send us a question about your separation and distillation applications, or about any of AMACS products. We’ll have a subject expert review and respond to your question within 2 business days.

AMACS will continue to invest in its website to provide you with the information and tools you need to make decisions and interact with us during the quote and implementation phases. As this is your site, we encourage you to provide feedback on the information and features you would like to see on it. You can send your comments and requests to amacs@amacs.com.

 We thank you for your patience while we have been constructing this site and continue to make it more intuitive to your needs.

About ACS Separation: 

ACS was founded in 1939 in Rhode Island to manufacture knitted copper wire mesh. By the 1950s, it had expanded into stainless steel wire mesh and additionally established the Separations Technology Division to in 1979. Over time ACS developed process engineering capability and expanded into vane separators, liquid – liquid coalescers as well as mass transfer products. In 1998, it became the North American licensee for Julius Montz GmbH’s structured packing product line. In 2010 ACS opened a factory in Monterrey, Mexico to add capacity to meet its growing sales.

 About AMISTCO Industries:

AMISTCO was founded in Houston in 1991 to manufacture mist eliminators based on its own wire knitting technology. It too expanded into vane separators and mass transfer products as it expanded its in-house process engineering capability. AMISTCO also invested in wedge wire screen manufacturing to serve the petrochemical as well as other industrial markets.

When designed correctly a standard mist eliminator collects essentially 100% of all liquid particles 10 microns and larger. They are used in the recovery of valuable products, to abate the emissions from chemical and refining processes, to meet industrial air pollution regulations, and to collect and remove fine liquid droplets in a vapor streams which otherwise may cause downstream corrosion of valuable equipment.

Utilizing mesh or plate surfaces to separate mist droplets from the gas stream through impingement. As the vapor moves through the demister, the inertia of the droplets causes them to contact the mesh surface, coalesce, and drain as larger droplets. The large surface area coupled with a small volume allows for the collection of liquid without impeding the gas flow.

Typically used to reduce the time needed to separate a liquid droplet size and therefore reduce the volume and cost of separator equipment, they are often used where vapor quality is critical with regard to entrained liquids, separator equipment costs are high or when space or weight savings are advantageous particularly inside a vessel.

Available in just about any size or shape and in a wide range of metals, fibers, plastics, and exotic alloys for maximum corrosion resistance, mist eliminator types include, mesh and coalescer pads, vane packs, insertion type Mist Fix and sub-micron fiber-beds . Each type is a distinct product, used in differing applications to achieve the basic job of demisting a vapor.

 When determining which style of mesh is to be used the following should be considered: 

1.  The flow rate and properties of the process gas.

2.  The flow rate and properties of the process liquid.

3.  The minimum micron size and efficiency of the liquid particles that are to be removed.

4.  The potential for clogging due to a viscous fluid.

Sizing and selecting mist eliminators requires analysis of the following: 

1.  The vapor velocity system limit for gravity separation defined by the Sounders-Brown equation.

2.  The vapor velocity at which re-entrainment occurs.

3.  The degree of separation required.

4.  The pressure drop across the mist eliminator and from the entrance and exit of the vessel

5.  Volume required for slug capacity
