Multimesh Column Packing INTRODUCTION
Multi Mesh column packing have over the years, become generally accepted as the most efficient packing for distillation towers operating at reduced pressure. Separation of heat sensitive, close boiling fractions calls for many theoretical stages and low pressure drop Multi Mesh column packing manufactured by SUMIT INDUSTRIES having a very low pressure drop per theoretical stage is precise solution to this problem. Any material which can be drown into a fine wire or filament can be used in the manufacture of Multi Mesh Column Packing's. However stainless steel 316 grades are readily stocked and other higher alloys are available on order. SALIENT FEATURES
1) The high voidage of Multi Mesh column packing manufactured by SUMIT INDUSTRIES allows free flow of both liquid and vapour through the packed column resulting in low pressure drop per unit height of the packing P/Theoretical = 0.05 ¬ 0.75
2) The high surface area of Multi Mesh column packing manufactured by SUMIT INDUSTRIES permits an intimate contact between vapour and liquid, resulting in low values of HETP 100 to200 mm in production column.
3) The low bulk density of Multi Mesh column packing manufactured by SUMIT INDUSTRIES result in decreasing the dead weight of the packed column. It also result in a lower shell thickness.
4) The HETP (Height equivalent of theoretical plate) of Multi Mesh column packing manufactured by SUMIT INDUSTRIES is less than 15 cm over the entire range of velocity.
5) Due to the capillary effect or multifilament mesh of Multi Mesh column packing wall effect is almost completely eliminated.
6) The flooding velocity of Multi Mesh column packing manufactured by SUMIT INDUSTRIES is 2-2.5 times higher than those of conventional packing's. This depending upon the requirement will reduce the column diameter or will reduce the column diameter or will increase the throughput. ADVANTAGES
1) Improve performance of existing columns. You can upgrade existing processes by replacing random packing's or trays with Multi Mesh column packing column packing manufactured by SUMIT INDUSTRIES. This simple change can result in increased product quality, higher production capacity and lower pressure by permitting the use of lower reflux ratios resulting in lower reboiler duty.
2) Reduced cost of new packed column systems. The high efficiency of Multi Mesh column packing manufactured by SUMIT INDUSTRIES permits
significant reductions in tower diameter and height, minimizing structural, foundation, piping, insulation and installation costs on new project.
3) Turn down-due to its capillary nature, the efficiency of Multi Mesh column packing increase with decreasing loading thereby providing an extremely wide range of operating capabilities. TYPICAL APPLICATIONS
Multi Mesh column packing manufactured by SUMIT INDUSTRIES supersede all the conventional tower packing their characteristic and performance.
Some of the typical applications of Multi Mesh column packing are mentioned here.
Vacuum distillation service where pressure drop across the packed height is critical separation of close boiling components which requires a very large number of theoretical plates.
Where components are thermally unstable Multi Mesh column packing are indispensable.
