SHORT-CUT METHOD OF REGENERATION ENERGY CALCULATION FOR CARBON DIOXIDE CAPTURE SYSTEM USING AN AQUEOUS-BASED CARBON DIOXIDE CAPTURE SOLVENT

摘要

The present invention relates to a regeneration energy calculation method of a carbon dioxide capture system using a wet carbon dioxide solvent, which is accurate, simple, and capable of saving time and costs. The regeneration energy calculation method of a carbon dioxide capture system comprises: a first step of dividing a regeneration tower to an assumption area and a non-assumption area, wherein the assumption area is an area to which an assumption that a temperature of a RICHIN stream flowing into an upper part of the regeneration tower by capturing carbon dioxide and a temperature of the upper part of the regeneration tower are the same can be applied, and the non-assumption area is an area to which the assumption cannot be applied; a second step of calculating regeneration energy (Qregen) from the assumption area; a third step of calculating regeneration energy (Qregen) from the non-assumption area; and a fourth step of calculating total regeneration energy by combining the regeneration energy calculated from each of the second step and the third step.
