tsa co 2 removal rate from the flue gas 90 co 2 working capacity for the adsorbent 2 conservative estimate adsorption desorption cycle time in tsa 6 minutes 0 1 hours sorbent utilization 60 conservative estimate according to these assumptions the total amount of ptfe with embedded sorbent required can be calculated 3 750 tons is 30 of the original 12 500 tons of sorbent required by the typical tsa process thus only 30 of the material would be required the apparatus 20 includes sheets of ptfe tape 21 embedded with sorbent and spacers 22 to provide channels 23 between adjacent sheets of ptfe tape 21 the spacers 22 may be of a flexible material and may include a matrix of channels or other suitable configuration to allow the flow of gas therethrough this configuration allows the flue gas to flow through the channels 23 of the adjacent sheets 21 such that the flue gas comes into contact with the sorbents contained in the tape 21 assuming the bulk density of apparatus 20 to be approximately 0 5 tons m 3 tape with spacer material the apparatus 20 would require 3 750 0 5 7 500 m 3 of material for a 500 mwe plant compared to 15 600 m 3 for a typical tsa sorbent bed table 1 the material.
