Benefits of LICUFLON® PTFE and POLYFLURON® PTFE LICUFLON and POLYFLURON PTFE are suitable for lining columns, reactors and vessels of up to 3000 mm in diameter. The materials available for the steel shell are high-quality carbon and stainless steel in various grades. Design, manufacture and testing all conform to the international standards specified, e.g. the European Pressure Equipment Directive (PED), ASME Section VIII, Div. 2, or the "China Stamp". Seismic and windload calculations can be carried out in addition to the mechanical stress calculations. Equipment lined with LICUFLON® or...

PTFE-Lined Bottom and Top Plates Flat solid bottom and top plates allow a plain but durable lining with LICUFLON or POLYFLURON PTFE. On request, the bottom plates can be produced in a slightly conical shape on the inside to facilitate drainage. Lined bottom and top plates can be fitted with one or more nozzles. Nozzles with flange dimensions meeting DIN 2501 PN 10 or ASME B 16.5 150 lbs are supplied as standard. We welcome inquiries about special flange dimensions.

Column Internals Distributors and support grids are available in a wide range of designs and materials such as PTFE/ PFA (also available with steel core), DIABON® graphite and carbon fiber-reinforced carbon (C/C). Depending on the application and design involved, they can be either flanged direct between the column sections or placed on support rings, which are themselves flanged between two column sections. Support rings are PTFE-lined steel rings bolted to the upper column section. This special design allows dismantling of the column without the need to remove the packing above or the...

Column Internals Support grids are used to hold the mass transfer packing in place. They are available either in the form of interlocking PTFE supports (Fig. 1), or as PTFE-lined metal tubes, DIABON graphite or carbon fiber-reinforced carbon (CFC) supports for use at higher bearing loads and elevated temperatures. Fig. 1: Both the distributor and redistributor are designed to meet the individual process requirements. The photos below show distributors made of PTFE and DIABON graphite.

Process Optimization and Process Design One main reason for declining efficiency in columns with random or structured packings is poor liquid distribution (wall effect). PTFE downcomers as shown below are a suitable remedy and avoid the need for costly redistributors.

Process Optimization and Process Design Standard columns with mass transfer packings in the corrosive service have a bottle-neck at the support grids. Especially high packing beds in large diameter columns at high temperatures need strong support grids, which leads usually to small free flow cross-sections. The solution provides our support grid made of SIGRABOND® with large free flow crosssection due to the high specific strength and the wide corrosion resistance even at high temperatures. Segmented SIGRABOND® support grid Finite Element Analysis for optimization Process Design Our...
