AMT HIGH EFFICIENCY AND CONVENTIONAL PACKING
AMT offers structured packing, random packing, and grid packing as well as supporting tower internals. These products are available in a wide variety of styles and material type including metal, plastic, and ceramic. AMT employs a fully automated production line allowing simultaneous high quality large scale production and delivery for new, revamp, or modernization projects all around the world. AMT has provided packing to many of the world’s largest plants around the worlds and designed and supplied internals and packing for columns with inner diameters up to 40’ [12.0 m].
High Efficiency Structured Random Packing
AMT’S PACKING PRODUCTS
SEPAK ® Structured Random Packing (SPR)
In 2013, ZEHUA (AMT’s parent company) developed and added a new class of packing termed “SEPAK ® Structured Random Packing”, or SPR, to the established SEPAK ® high performance packing suite of products. SPR combines advantageous features of both structured and random packing into an innovative and powerful mass transfer technology.
With SPR packing, the discrete geometric shapes of random packing are produced in a structured format and can be installed in the same manner as structured packing.
Hydraulic air/water tests conclude that SPR packing demonstrated lower pressure drop throughout varying liquid and vapor rates when compared to other commonly used structured and random packing types. Moreover, SPR packing resulted in the greatest efficiency in a gas absorption study (CO2-NaOH system) when compared to several types of high performance random packings. The test results demonstrated that the advantages in efficiency and capacity are more pronounced at higher liquid rates, typical for gas absorption and high pressure applications.
In summary, SPR Structured Random Packing has been proven via extensive testing to deliver superior efficiency and capacity compared to other structured and/or random packing types commercially applied today. In addition, SPR packing offers an economical value for high performance packing to end users by utilizing less material per volume compared to other random packing types, which results in cost savings.
There are currently (3) different types of SPR packing available, with serial number #1, #2 and #3. Please refer to below charts for testing data of SPR #1, #2 and #3 Packing.
AMT's SEPAK® structured packing series are made of surface enhanced, corrugated sheet metal/woven wire gauze. With unique surface treatment, liquid will form thin film on the surface, and liquid spreading will be enhanced even in low liquid rate operations. Thus, the completely wetted structured packing surface will provide ideal liquid-vapor contact. Packing Performance has been certified by several multinational companies and has been used in industrial applications up to a diameter of 40’ [12.0 m].
AMT designs and manufactures conventional and high performance random packing in all industry standard or specialized materials and thicknesses to service nearly any mass transfer requirements. Random packing is constructed of many loose shaped metal pieces that maximize liquid / vapor or liquid / liquid contact area through an area filled with these pieces called a packed bed. Random packing is idea for columns with increased fouling or corrosion and offers easier replacement and storage when compared with structured packing.
AMT designs and manufactures structured packing in all industry standard or specialized materials and thicknesses to service nearly any mass transfer requirements. Structured packing minimizes pressure drop and increases efficiency. Structured packing also improves fouling resistance, packing serviceability, ease of cleaning, and mechanical strength when compared with random packing. Structured packing is constructed of shaped metal sheets welded into rigid grid structures and stacked inside packed columns in layers typically made of many grids shaped to fill the column cross section.
