2 Wherever in the world in all continents Raschig jaeger is on the strategic acquisition combining Raschig and jaeger into onelarger group gives a great advantageto our customers giving them access to products of both entitiesin Europe, The Americas and in other partsof the world. It will create new dimensions in mass transfer technology. The advantages of our processengineering know-how and our technologies benefit even more the planning, modernization andconstruction of our clients processes. And: saving energy and investment cost is part of new alliance offers a diverse array of products to meet themass transfer needs of the industries. Whilespecializing in high performance products, the comprehensive products line of Raschig jaeger alsoincludes traditional fractional trays as well as structured andrandom packing types that best fit In-house distributor test-facilityThe company operates one of the largest in-house distributor test-facilities worldwide.

5 Themaximum operating temperatures for these different resins vary from material to material and are also affectedby specific process variables. The data presented below correspond to maximum continuous operatingtemperatures at atmospheric pressure and systems that are essentially air and water. The presence ofsolvents, acids, free radicals, and oxidants needs to be considered. Furthermore, these temperaturescorrespond to the maximum recommended bed depth for each packingsize and material. These maximumbed depths are different depending on the application.

If you chose columnB,then you might be in for a :Which column design is less expensive?

7 Answer:Column AThe price you pay for pollution abatement iscomposed of two parts. First, there s the directcapital cost for the scrubber or stripper. Thisincludes the up-front money you are charged forthe column, the packing and the internals. Butthere s also an ongoing energy expense that youmust pay for gas compression and for liquidpumping. The capital cost is usually carefullymonitored and controlled because it is oftentimesa large lump sum payment charged beforeabatement even contrast, energy is paid for on an ongoingbasis. It is a cost not often considered in theevaluation of designs submitted by differentvendors because it is presumed that this costshould be about the same for all designs. It thenfollows that the cost for abatement is minimizedby minimizing the capital expense.

8 But thisreasoning can be seriously flawed. Energy costsare extremely sensitive to design choices likecolumn diameter, packed depth, gas loading persquare foot of column cross sec-tion, and materials of construction. The only proper way to choose a designis to balance capital expenses against operating expenses. The annual abatement cost is the sum of thedepreciated capital cost and the annual energy cost. The properchoices of column diameter, packed depth,and gas loading per unit cross section are those that minimize this annual abatement cost. When the capitaldepreciation time is relatively long, the column diameter increases in order to bring the pressure drop downand thus lower energy costs. Conversely, when capital is depreciated more quickly, the column size shrinks(at the expense of higher pressure drop) in order to lower the up front expense.

9 In short, then, a smallercolumn can be more expensive to operate than a larger one when all cost factors are taken into accountJaeger can work closely with your organization to develop cost models for yourproject and we can optimize a design based on these models to meet yourfinancial objectives.

The partialresults shown in the two graphs at the leftshow why they picked 31/2 jaeger Tri-Packs over 31/2 Lanpac as the most efficient andaffordable packing these two products-of comparable size-are used for identical purposes with identicalconditions, the 31/2 jaeger Tri-Packs overwhelmingly outperform the 31/2 Lanpac .Stripping efficiencies for 31/2 jaeger Tri-Packs averaged better than those for31/2 Lanpac . These results are illustrated bythe graph at the top same trend is evident in the pressuredrop, as illustrated by the graph on the lowerleft. The data shows the advantage in energysavings that 31/2 jaeger Tri-Packs offersover the 31/2 Lanpac .31/2 jaeger Tri-Packs were recommendedand installed because they outperformed 31/2 Lanpac in both mass transfer efficiency andpressure drop.
