Retrofit or Adjustment Factors

← Previous | Next →

See Retrofit or Adjustment Factor Inputs for an explanation of retrofit costs. We do not recommend using the 2-Step w/ Air Sweep or NETL 2-Step w/ Sweep configurations for retrofit analysis. The membrane system has the following capital cost process areas:

•Membrane Module: (Not shown for NETL 2-Step w/ Sweep) This is the direct cost of the membrane module.

•Membrane Frame: (Not shown for NETL 2-Step w/ Sweep) This is the direct cost of the membrane frame structure.

•Compressors: (Only shown for 2-Stage Cascade) This is the direct cost of the feed-side compressors.

•Expander: (Only shown for 2-Stage Cascade) This is the direct cost of the expander.

•Vacuum Pumps: (Not shown for NETL 2-Step w/ Sweep) This is the direct cost of the permeate-side vacuum pumps.

•Heat Exchangers: (Only shown for 2-Stage Cascade) This is the direct cost of the heat exchangers.

•CO2 Drying and Compression Unit: (Only shown for 2-Stage Cascade) CO2 is dried and compressed to liquid form for transport over long distances.

•CO2 Cryogenic Purification Unit: (Only shown for 2-Step w/ Air Sweep) The CPU purifies, dries and compresses the CO2.

•CO2 Removal System: (Only shown for NETL 2-Step w/ Sweep) This is the direct cost of the CO2 removal system.

•CO2 Compression: (Only shown for NETL 2-Step w/ Sweep) This is the direct cost of the CO2 compression system.
