PACKING OF CROSS-CHANNEL STRUCTURE FOR MASS-TRANSFER PACKED COLUMN AT HIGH SPECIFIC CAPACITY OF SEPARATION AND METHOD OF OPERATION OF SUCH COLUMN Russian patent published in 2002 - IPC

FIELD: mass- transfer checked columns. SUBSTANCE: specific surface of packing has angle ϕ of inclination of channels. It belongs to class (c1) at Ca = a_c1 and ϕ = ϕ_c1 according to the following data: similar flows of liquids are preset for liquids flowing through packing; number "n" of theoretical stages of separation per meter is determined empirically, viz.: NTSM magnitude appears in form of first function f₁(a,ϕ) of the variables "a" and ϕ; hydraulic resistance arising for gas flow running through packing is characterized by loss of pressure per meter, Δp as second function f₂(a,ϕ); magnitude Δp has relative minimum at additional condition n=const when variable "a" and ϕ appear in form of magnitudes a_m(n) and ϕ_m(n) depending on magnitude "n"; conditions n > 4,5 a_cl< a_m(n), ϕ_c1> ϕ_m(n), as well as ϕ_c1> 45^° are true. EFFECT: enhanced economical efficiency of separation. 9 cl, 4 dwg
