DEVICE AND METHOD FOR ANALYZING GAS COMPOSITION

摘要

The present invention provides a device for analyzing gas composition. According an embodiment of the present invention, the device for analyzing gas composition comprises: a multi-directional valve connected to a gas inflow unit into which acidic gas flows to alternately feed the acidic gas from the gas inflow unit to two or more moisture removal units in a sulfur collection device; a first moisture removal unit to remove moisture contained in the acidic gas fed by the multi-directional valve; a second moisture removal unit to remove the moisture contained in the acidic gas fed by the multi-directional valve; and a moisture removal control unit to control the multi-directional valve to feed the acidic gas to the second moisture removal unit if a quantity of moisture absorbed by the first moisture removal unit is larger than or equal to a predetermined reference value. The present invention analyzes the composition of acidic gas flowing into a sulfur collection process to optimally manage an operational condition of the sulfur collection process to increase a sulfur collection rate and prevent potential facility and work problems.
