We'll provide a PDF copy for your screen reader. The cost of the structure, packing, and pumps must be. Membrane Systems Planning and Design. Usually, a soil-venting system is combined with an air-sparging system for vapor extraction, with the gaseous pollutants treated, as in air stripping. T he hydraulic loading rate on the stripping tower can af fect the. The pressure drop is directly.
Roberts and Levy 4 performed a similar ener gy-cost analysis for. T ypical relationships between pump. The head tank was used to provide constant pressure at the l i q u i d rotameter, thereby f a c i l i t a t i n g reasonably constant l i q u i d flow to the column. Because of these drawbacks, ammonia stripping is limited to applications when other treatment approaches would not be feasible or economical. Login Through Your Library. The foul-condensate experiments demonstrated that from the p o i n t of view of mass t r a n s f e r , methanol behavior i n f o u l condensates i s the same as i n d i l u t e s o l u t i o n s of methanol i n water. Selected major factors include the following:
Steam stripping | EMIS
However, i f the s t r i p p e r off-gas was not added u n t i l a f t e r the ambient a i r was preheated, there would be no condensation. Selecting an air stripper for which the design flow is at the lo wer end. Demonstration of Steady-State The approach of experimental c o n d i t i o n s to steady-state was monitored mainly by the outputs of thermocouples numbers 1, 15, 25 and 32 on the Watanabe recorder. The three othersexperiments, F l to F3, invo l v e d f o u l condensates. This packed bed a l s o provided insurance that the mixing of the steam and a i r would be complete. I f s u f f i c i e n t q u a n t i t i e s of terpenes are present, some m i l l s put the vent condensate through a decanter to recover sulphate turpentine as a by-product.

For e xample, the a verage concentrations of nitrogen. In or der to remove ammonia from w ater , the dissolved NH. This is lar ger than the value of 66 ft calculated for the. Therefore, experiments 1 and 2 were conducted under very s i m i l a r c o n d i t i o n s. Handbook of En vir onmental Engineering. Nevertheless, some common trends were
