PLANT FOR PHASE-SELECTIVE ADSORPTION OR ION EXCHANGE OF COMPONENT FROM DISPERSED FLUID OR LIQUID MEDIUM AND METHOD OF PHASE-SELECTIVE ADSORPTION OR ION EXCHANGE OF COMPONENT FROM DISPERSED FLUID OR LIQUID MEDIUM

摘要

FIELD: technology of adsorption and ion exchange processes for extraction and separation of components of dispersed and liquid media.;SUBSTANCE: proposed plant includes mixing reactor, displacement apparatus, two-section mass exchanger and pulsating system interconnected into suspension sorbent circulating loop. Sections of mass exchanger are made in form of extended passages divided by convectively permeable partition. Pulsating system forms alternating drops of pressure in passages. One passage of mass exchanger is connected to loop and other passage is connected to line of counter-flow delivery of medium to be treated. Loop is connected with fresh sorbent source and with used sorbent receiver. Line of medium to be treated is connected with carrying fluid source and receiver. Sections of mass exchanger may be of shell-and-tube type or of contact-plate type. Specification describes methods of phase-selective adsorption or ion exchange. Fresh sorbent is kept in source and is introduced into loop in form of concentrated fluid suspension in carrying preserving liquid. Waste sorbent is discharged from loop also in form of concentrated suspension. Size of dispersed particles of adsorbents, ionites and media being treated range from 0.3 to 0.7 mm. Adsorption or ion exchange processes are carried out in cyclic, continuous cyclic and fully continuous modes. As a result, productivity by component being extracted is increased by 5-10 times.;EFFECT: increased productivity; reduced number of production processes and equipment units.;23 cl, 3 dwg, 1 tbl, 21 ex
