본 발명은 이산화탄소 흡수용액에 관련된 것이며, 보다 구체적으로는 화석연료의 연소에 있어서 발생하는 연소가스에서 지구온난화가스인 이산화탄소를 제거하는 할 수 있는 흡수용액의 흡수평형 시험방법 및 그 장치에 관한 것이다.The present invention relates to a carbon dioxide absorption solution, and more particularly, to an absorption equilibrium test method and apparatus for removing carbon dioxide, which is a global warming gas, from a combustion gas generated in combustion of fossil fuels.

일반적으로 이산화탄소 흡수분리용 흡수용액의 흡수정도(흡수율, 흡수속도)를 측정하기 위한 흡수평형시험은 연소가스 중에 이산화탄소를 혼합가스로부터 흡수분리하기 위한 흡수용액의 개발에 있어서 매우 중요한 요소이다. 연소배기가스 중에 포함된 이산화탄소를 흡수제거하기 위한 흡수용액의 개발을 위한 흡수용액의 흡수정도를 알아보기 위한 시험장치는 종래에는 흡수 반응조에 적당량의 흡수용액을 충전하고 혼합가스 혹은 이산화탄소를 주입하여 흡수용액에 이산화탄소가 흡수됨으로써 흡수반응조의 압력이 감소하는 것을 측정하는 방식으로 이루어졌다. 이런 종래의 방식은 반응조의 온도를 시험에 필요한 조건으로 조절할 수 없고, 흡수반응조의 압력을 높이지 못한 상태의 대기압에서 시험하는 단점이 있다. 그러므로 흡수반응온도가 높은 범위 혹은 압력이 높은 조건에서는 이산화탄소의 흡수평형시험을 수행하지 못해 고온 또는 고압 상태에서 개발된 흡수용액이 실제 상용공정에 적용하기 위하여 다른 장치에서 시험을 거쳐야 하는 어려움이 있는 문제점이 있다.In general, the absorption equilibrium test for measuring the absorption degree (absorption rate, absorption rate) of the absorption solution for carbon dioxide absorption separation is a very important factor in the development of the absorption solution for absorption separation of carbon dioxide from the mixed gas in the combustion gas. A test apparatus for determining the absorption level of an absorption solution for the development of an absorption solution for absorbing and removing carbon dioxide contained in combustion exhaust gas is conventionally filled with an absorption solution in an absorption tank and injecting mixed gas or carbon dioxide to absorb the absorption solution. This was done by measuring the decrease in pressure in the absorption reactor by the absorption of carbon dioxide. This conventional method has a disadvantage in that the temperature of the reaction tank cannot be adjusted to the conditions necessary for the test, and the test is performed at atmospheric pressure without raising the pressure of the absorption reactor. Therefore, the absorption equilibrium test of carbon dioxide cannot be performed in the range of high absorption temperature or high pressure, so the absorption solution developed at high temperature or high pressure has to be tested in other devices in order to be applied to actual commercial process. There is this.

Next, the temperature of the air thermostat 1 is tested by increasing the temperature of the air supplied to the air thermostat 1 through the electric heater 6 by operating the air blower 5 located below the air thermostat 1. (S50) At this time, the supplied heating air is heated inside the air thermostat 1 by turbulence generated by the air flow inhibiting iron pieces 7 attached to the outer wall of the air thermostat 1. The temperature is kept constant. This is to control the air discharge by using the air outlet 14 located above the air thermostat 1, the temperature of the air thermostat 1 in a short time due to the turbulence generated by the air flow inhibiting iron pieces (7) By letting rise, the temperature of the air thermostat 1 can be kept constant. Next, if the proper temperature is maintained for the test of the air thermostat (1) and the absorption reactor (3), the absorption reactor (3) by operating the mixer (4) for mixing the gas and the absorption solution with a magnetic motor attached to the outside of the apparatus (S60) Next, the mixed gas supply valve 10 is opened in the mixed gas storage tank 2 in which carbon dioxide is stored so that CO 2 gas is supplied to the absorption reaction tank 3 (S70). It is preferable to maintain the internal pressure CO2 of the absorption reactor 3 suitable for the conditions. From this time, the test is started to measure the degree of absorption of the CO 2 gas into the absorbing solution in real time in the gas analyzer 13, and the pressure and temperature in the absorption reactor 3 in real time in the data processing device 12. The present invention is achieved by performing a carbon dioxide absorption reaction equilibrium test. (S80) Thus, the absorption equilibrium test apparatus for removing carbon dioxide absorption from the mixed gas of the present invention is a mixed gas storage tank (2) and absorption in the air thermostat (1). By installing the reactor (3) to supply air through the electric heater (6) installed under the air thermostat (1) to control the temperature in the system required for the absorption reaction test in a short time, outside the air thermostat (1) By operating the installed gas supply valve as needed, the mixed gas of the mixed gas storage tank 2 can be easily absorbed into the absorption reaction tank 3 under any high temperature or high pressure conditions. Can be supplied.

At present, carbon dioxide emissions from combustion gas generated by fossil fuel combustion in thermal power plants account for a very high proportion in the industrial sectors of non-energy sectors, and are actively promoting technology development to reduce carbon dioxide. The present invention proposes a test method and apparatus that can be very usefully used to develop an absorbent used in the process of absorbing and removing carbon dioxide contained in combustion gas with the above configuration. The absorption equilibrium test apparatus for removing carbon dioxide is a device capable of testing the degree of absorption (absorption rate, absorption rate) of carbon dioxide, which is a greenhouse gas contained in a mixed gas such as combustion gas, selectively. Combustion flue gases produced by burning fossil fuels (coal, petroleum, and natural gas) vary depending on the combustion conditions, but most of them produce about 12-18% of carbon dioxide, about 3-8% of oxygen, and other mixed gases. Within about 1%, the remaining gas consists of nitrogen.
