Distillation column

CRP design and manufacture absorption and distillation columns lined in HiPerflon® PTFE / PFA. The reliability of such columns is grounded in using the best lining materials, with no seams or welds, which are often weak points in a construction. CRP are constructing columns from paste extruded PTFE liners with heavy walls up to 7/16″ thick without seams or welds. Where nozzles are required we are producing these sections with a PFA moulded homogeneous fluoropolymer lining so that we don’t require bolted on branches. Lining that is designed to last Our PFA lining can be up to 1/2″ thick depending on nominal bore. We are offering columns with such heavy wall thicknesses of liner so that the column can operate for the maximum length of time. A thicker lining is proven to slow down and even stop permeation of the columns contents and for chemistries containing hydrochloric or nitric acid for example this is an important benefit of the CRP approach to fluoropolymer lined columns manufacture. High vacuum performance High vacuum performance is always a challenge with large diameters because the hoop strength which aids with this on smaller diameters is no longer present. CRP are leading the way in resolving this issue by innovatively supplying the PFA linings with an integral steel mesh reinforcement welded to the steel substrate to support and resist vacuum even at high temperatures. Non-stick smooth surfaces The HiPerFlon® linings we use provide a very smooth internal finish with a high wettability much surpassing stainless steel for example and can be successfully used in ultra-high purity applications.
