Pilot scale applied research on CO2 removal of natural gas using a rotating packed bed with propylene carbonate

Experimental Investigation and Correlation of Liquid-Side Mass Transfer in Pilot-Scale Rotating Packed Beds

“…Packing material: stainless steel (SS), modeling approaches: theoretical mechanistic (TM), semiempirical (SE) Figure 1. Radial bed lengths of countercurrently operated single-block packing RPBs used to investigate k L a e in the literature, the RPB used in this study, and RPBs referred to as pilot scale in the literature used to study other processes (CO 2 absorption in MEA, 20,23 H 2 S absorption, 21 NH 3 stripping, 22 CO 2 absorption to determine a e , 2424 CO 2 absorption in propylene carbonate, 25 cocurrent water deoxygenation 12 ). in co-and counter-rotation, made from metal foam, have been developed by Rajan et al, 15 Reddy et al, 31 .…”

“…Only a few studies of k L a e are available for RPBs with radial bed lengths well beyond 100 mm, hereafter termed pilot scale. While there is no sharp boundary as to when an RPB should be considered pilot scale, the proposed nomenclature is in line with the use of the term in the literature. ,− Radial bed lengths of several RPBs referred to as “pilot scale” in the literature are shown as the rightmost gray bars in Figure . Axial bed height is not considered as a criterion, since it should have a minor impact on performance when liquid is uniformly distributed, in analogy to the diameter in columns. , Industrial-scale RPBs may have similar radial bed lengths as pilot scale machines, but will usually have greater inner radii and axial heights to accommodate increased gas and liquid throughputs …”

Experimental Investigation of Mass Transfer Intensification for CO2 Capture by Environment-Friendly Water Based Nanofluid Solvents in a Rotating Packed Bed

“…(a) Examination of chemical solvents like propylene carbonate to evaluate the absorption ability [32]; mixed-chemical solvents, as in Ref. [33]; or new advanced-green solvent performance in acid gas treatment, such as ionic liquids [34] and nanofluids [31].…”

“…Jiao et al [55] examined the performance of an RPB in a Q L range of 0.5-1 L/min and a Q G range of 667-1667 L/min at 1 bar and 298 K. Generally, Xing et al [56] showed RPB performance at atmospheric pressure in different rotational speeds and a vast gas-liquid ratio (GLR) range of more than 20 and up to 20,000, as summarized in Table 1. In addition, Xiang et al [32] evaluated CO 2 absorption with propylene carbonate in a pilot-scale RPB at a gas flow rate of 8-25 m 3 /h and liquid flow rate of 100-300 L/h at high pressure and a rotating speed of 290-1450 rpm. The higher possible GLR for CO 2 absorption in an RPB is an important parameter to provide economical performance, as reported in [63], which allows operation with the lowest absorption solvent solution.…”
