There is disclosed a method of separating and recovering carbon dioxide from combustion exhausted gas, which method includes: bringing the combustion exhausted gas in contact with water, under a pressure-increased condition, to form carbon dioxide hydrate; and thus separating and recovering carbon dioxide contained in the combustion exhausted gas. According to the method, CO of high purity can be separated and recovered from the combustion exhausted gas at low cost and with low energy consumption. There is also disclosed an apparatus for separation and recovery of CO which apparatus is employed in the method.

Method of separating and recovering carbon dioxide from combustion exhausted gas and apparatus therefor

A nozzle for water jet cutting has a piezoelectric element provided at a position for acting on a fluid in its pressure chamber. A voltage varying with time is applied to the piezoelectric element to provide flow rate oscillation or pressure pulsation to the fluid which is jetted from the nozzle.
