Therefore, basic design of two scrubbers after the reactors are considered to be finished. 0000000839 00000 n 68-02-2612 Task No. startxref and specified worldwide. 7. 340 14 Examples for the design of packed columns Yo = mYXXo-Y0 (14-13) Yu = mYXXu-Yu (14-14) The corresponding equations for the liquid phase are = xu 1 mYX 1 mYX Yo Yu (14-16) (14-17) In a rectification process, as illustrated in Fig. 1. It is a 32 bit application but will run under the 64 bit versions of these operating systems. K mass transfer coefficient, moles/time/area. 0000002972 00000 n 0000002621 00000 n Selective Non-Catalytic Reduction (SNCR) Air pollution control devices used to control gaseous pollutants are: Wet Gas Scrubbers, Packed-Bed Scrubbers… 0000007505 00000 n Packed-bed scrubbers provide excellent gas-liquid contact and efficient mass transfer; they can generally be smaller in size than spray scrubbers and so are an effective option when space is limited. The common designs of the packed bed scrubber are cross flow and counter current flow. A wet scrubber, or wet scrubber system, is a type of pollution control equipment that is designed to remove harmful gases and particulates from industrial exhaust streams. G molar vapor rate in a column. �8�@4���aoe��Q�2� g0��T��4�O�6��2����"%$� \8��-F��9���N���ꆴ#5��`%�A�0�����`��`R�H. a interfacial mass transfer area per volume of packed bed. Although wet particle scrubbers will also provide mass transfer removal of some gases, these four types of absorption scrubbers will do the job more completely and with greater efficiency. In this project, the efficiencies of cross flow and counter current flow packed bed wet scrubbers used in Penang, Malaysia are studied and compared. 0000084269 00000 n Cleaning efficiency: 70% of … x�b```��,�V� cb����Z���R��x�] ��c�Y�t�sg8�o��-��C�/�3v�?\zݙ�0���7�/��Y�=�+;�u�z��i���y�g��={Wϝ�w���P��. �5�(_l14w0������\f�3�\9�-!V��D-j�$���ґك.w)����^�{ꧥ�@^"��"��,~�4�Q�辙�Q�> 0000000016 00000 n 104 18 The scrubber packed bed, scrubber body, mist elimi-nator, and transitions should be thoroughly cleaned with a hose spray nozzle to wash any foreign mate-rial out of scrubber sump prior to connecting drain piping. 0000000685 00000 n 14.1, the reflux ratio is given by Packed tower scrubbers (also referred to as packed bed or packed column scrubbers) are designed for chemical scrubbing of contaminants from gas streams.

The scrubber packed bed, scrubber body, mist elimi-nator, and transitions should be thoroughly cleaned with a hose spray nozzle to wash any foreign mate-rial out of scrubber sump prior to connecting drain piping. The scrubber is a packed tower with Intalox saddles and is made of Carbon Steel. %PDF-1.4 %���� The droplets entrain and capture dust particles through agglomeration, adherence, or encapsulation. Wet Gas Scrubber 2. G molar vapor rate in a column. Tri-Mer packed bed scrubbers are versatile, reliable systems that serve the widest variety of processes. A spray header located at the inlet initiates the gas/liquid contact and provides irrigation at the front of the packed bed.
