Structured packings for separation and reactive distillationThis brochure was reviewed and supplementedrecently.Ittherefore provides a complete, up-to-date overview of packings available fromSulzerChemtech. Also included is a summary coveringtheessentialcolumninternals andourtechnicalservices. Forfurtherinformationandtodown- load our brochures as well as designtools,pleasereferto www.sulzerchemtech.com More detailed product information, you will find in the following brochures: - Internals for Packed Columns Thebrochurecontainsacomprehensivesummaryoftheselection of internals supplied by Sulzer Chemtech, and a description of the most important features of thedistributortechnology. - Gas Processing - Chemical Processing Industry - Process Technology and Equipment for Oil Refineries and Crude Oil Production Three brochures which illustrate thewidespectrumofapplication ofstructuredpackings. Sulcol Design Program A program that enables users to carry out hydraulic design of columns featuring every type of packing Sulzer Chemtech offers. The program is based on our ex- perience with several thousand industrial columns and from experimental data measured in our owntestcolumnwithadiameterof 1m. Considering the broad selection of products and widely proven application know-how, Sulzer Chemtech is in a position to offer the suitable solution even for the mostdifficultseparationtasks.

50 years of experience in mass transfer technologySulzerChemtechhasbeenactiveasequipmentsuppliertothechemical industry since the nineteen fourties. In the early days the engineering design was completely dependent on the specification provided by customers. At the end of the fifties Sulzer was ready to offer its own solutionstospecificchemicalprocessengineeringproblems.Theseearly activitieslaidthecornerstoneforsustainedinnovationbyestablishingan in-housedevelopmentgroupandawellequippedpilotfacility. Gauze packings Theinventionofthegauzepackings BX and CY in the early sixties resultedinadecisivebreakthrough indistillationtechnology.Thespecial advantages of these packings allowed difficult separation tasks to be accomplished for the very first time, and thermally sensitive substances to be separated by meansofdistillation. for natural gas drying. In comparison to conventional technology, Mellapakofferssubstantialbenefits in many process applications. Duringthepast40years,thousands ofcolumns,originallyequippedwith trays or random packings, have been revamped with Mellapak in ordertoimproveyieldorpurityorto increasecapacity.Duetoextensive test data gathered in our process engineering laboratory as well as experience gained in numerous industrialapplications,weareable to offer the best possible solution foryourapplicationrequirements. Column Internals With the concept of advanced internals, Sulzer Chemtech has defined the standard for gas and liquid distribution in packed columns.Distributorsareavailable for a wide range of applications andoperatingconditions.

Mellapak A further milestone was the developmentofthestructuredpackings Mellapakintheseventies.Originally conceived to cover the moderate vacuum range up to atmospheric pressure,Mellapakopenedupnew andunforeseenperspectivesinall areasofthermalmasstransfer. Applications The eighties were marked by the widening of the application range of Mellapak in the petrochemical, oil and gas industries as well as in exhaust air cleaning and in the strippping of volatile constituents fromwastewater.Typicalexamples arevacuumtowersinrefineriesand high-pressure absorption columns
