Abstract

A method of capturing an acid gas includes: an adsorption step; a desorption step; and a cooling step in the stated order. In the adsorption step, an acid gas is caused to be adsorbed to an acid gas adsorption material by supplying a gas to be treated containing the acid gas to an acid gas adsorption device including the acid gas adsorption material. In the desorption step, the acid gas is caused to be desorbed from the acid gas adsorption material by heating the acid gas adsorption device. In the cooling step, the acid gas adsorption device is cooled with a cooling medium having a temperature less than an outside air temperature.

Abstract

A method of capturing an acid gas includes an adsorption step and a desorption step. In the desorption step, the acid gas is caused to be desorbed from the acid gas adsorption material by heating the acid gas adsorption device. The desorption step includes a first desorption step and a second desorption step after at least the first desorption step. In the first desorption step, a first desorption gas is supplied to the acid gas adsorption device so that an acid gas desorbed from the acid gas adsorption material is captured together with the first desorption gas. In the second desorption step, a second desorption gas with lower humidity than humidity of the first desorption gas is supplied to the acid gas adsorption device so that an acid gas desorbed from the acid gas adsorption material is captured together with the second desorption gas.

Abstract

In the present invention, a computer acquires a parameter value set including values of a plurality of parameters each classified into at least one among a plurality of factors affecting the generation of crystals. The computer inputs the parameter value set into a crystal generation model to make a prediction pertaining to the generation of a crystalline form that a substance may take. The crystal generation model represents a crystal generation process and includes elapsed time as an element. The computer outputs prediction result information which is information pertaining to the result of prediction.

Abstract

Provided is a gas sensor capable of accurately measuring the hydrogen gas concentration in a high-temperature gas to be measured. The gas sensor includes a sensor element and a control device. The sensor element includes: a gas-to-be-measured circulation cavity 15 having a gas introduction port 10, an oxygen discharge chamber 20, and a measurement chamber 61; an oxygen pump cell including an in-cavity oxygen pump electrode 22; and a measurement pump cell including an in-cavity measurement electrode 44. The in-cavity oxygen pump electrode 22 has catalytic activity with respect to oxygen and does not have catalytic activity for oxidizing hydrogen. A pump control unit included in the control device operates the oxygen pump cell to pump oxygen in the gas to be measured from the oxygen discharge chamber 20, and operates the measurement pump cell to pump oxygen into the measurement chamber 61 thereby oxidizing the hydrogen gas in the gas to be measured. A concentration calculation unit included in the control device calculates the hydrogen gas concentration in the gas to be measured on the basis of the value of the current flowing in the measurement pump cell.
