Sheet Metal |
The Sheet Metal type structured packing. Instead of using the expensive wire gauze materials, surface textured sheet metal was used to create a whole family of corrugated packing with a wide range of corrugation sizes and angles The AMACS family of sheet metal packing can handle a much wider range of vapor and liquid rates and process services. These process applications ranges from low pressure drop vacuum (and atmospheric) distillation services to medium high-pressure absorbers metal sheet packing can handle a moderate amount of fouling provided there is adequate liquid loading to keep the packing wetted. |

Whereas the above Structured Packings are intended for relatively cleaner mass transfer applications, AMACS Grid Structured Packing was developed to provide extended operation in fouling services. There are two types of grid structured packing; corrugated sheet metal and stamped blades connected into panels with cross rods. Both styles are highly durable with large open areas to accommodate highly fouling process streams. Unlike the thinner sheet metal packing, the Corrugated Grid Packing has a smooth surface to minimize the possibility of fouling. It is constructed of much thicker material than the normal sheet metal packing. The Bladed Grid Packing achieves its mass and heat transfer capabilities by creating a tortuous path for the vapor and liquid streams. The strength of this packing comes from the 14 or 16 gauge material used for the blades. Both styles of grid packing are used in services with low liquid loadings like crude vacuum column wash sections or in highly fouling services with heat transfer requirements like the FCC Main Fractionator Slurry Pumparound Beds. Grid Packing can be used to replace structured packing anywhere that fouling is a concern. | |
