摘要:
Provided are a CO 2 recovery unit and a CO 2 recovery method which enable stable operation to continue even if an operation condition has changed. This CO 2 recovery unit (1) is equipped with: a CO 2 -absorber (14) that causes CO 2 included in flue gas (11A) to be absorbed into a CO 2 -absorbing solution (13); a CO 2 -regenerator (15) which regenerates the CO 2 -absorbing solution (13) by heating; and a CO 2 recovery amount control unit (111) which calculates a computed target value for the CO 2 recovery amount and a computed target value for the CO 2 recovery rate on the basis of a set value for the CO 2 recovery rate, actual measured values of the CO 2 concentration, gas flow rate, and temperature of the flue gas (11A), and maximum values for the CO 2 recovery amounts in the CO 2 -absorber (14) and the CO 2 -regenerator (15). On the basis of the set value for the CO 2 recovery rate or the computed target value for the CO 2 recovery rate, the CO 2 recovery amount control unit (111) controls: the amount of the CO 2 -absorbing solution (13) supplied to the CO 2 -absorber (14); the amount of the CO 2 -absorbing solution (13) supplied to the CO 2 -regenerator (15); and the amount of saturated steam (S) supplied to a regeneration heater (31) of the CO 2 -regenerator (15).
摘要:
An electrochemical cell for the continuous acidification of alkaline water sources and recovery of carbon dioxide with simultaneous continuous hydrogen gas production having a center compartment, an electrolyte-free anode compartment having a mesh anode in direct contact with an ion permeable membrane, an endblock in direct contact with the anode where the endblock provides a gas escape route behind the anode, an electrolyte-free cathode compartment having a mesh cathode in direct contact with an ion permeable membrane, and an endblock in direct contact with the cathode where the endblock provides a gas escape route behind the cathode. Current applied to the electrochemical cell for generating hydrogen gas also lowers the pH of the alkaline water to produce carbon dioxide with no additional current or power. Also disclosed is the related method for continuously acidifying alkaline water sources and recovering carbon dioxide with continuous hydrogen gas production.

The object of the invention is a method for conducting a chemical reaction involving the powder catalyst, in particular ferromagnetic catalyst. The method is characterized in that while conducting a chemical reaction, particles of the catalyst comprising a ferromagnetic material are put into oscillation by the oscillating magnetic field with a frequency greater than 0.1 Hz and a magnetic field induction greater than 0.01 mT. Oscillating magnetic field here is a field the induction vector of which changes its direction in time. Putting catalyst particles into oscillation increases the efficiency of the chemical reaction by several dozen to several hundred percent.
