Abstract
There is provided a system including a monitoring unit that analyzes, using a sensor, components of a first gas which may include first components and a pre-separation unit disposed upstream of the monitoring unit. The pre-separation unit includes: a first supply line that supplies the first gas to the monitoring unit; a second supply line that supplies a second gas, which includes components obtained by removing the first components from the first gas using a first separator, to the monitoring unit; and an automatic valve station that periodically switches between the first supply line and the second supply line to alternately supply the first gas and the second gas to the monitoring unit.
Claims20
A system comprising:
- a monitoring unit that includes a sensor to analyze components of a first gas that has a possibility of including first components;
- and
- a pre-separation unit disposed upstream of the monitoring unit,
- wherein the pre-separation unit includes:
- a first separator configured to remove the first components from the first gas;
- a first supply line that is configured to supply the first gas to the monitoring unit;
- a second supply line that is configured to supply a second gas through the first separator, to the monitoring unit;
- and
- an automatic valve station that is configured to periodically switch between the first supply line and the second supply line to alternately supply the first gas and the second gas to the monitoring unit, and
- the system further comprises a control module configured to control the automatic valve station;
- wherein the automatic valve station includes a first valve that is configured to shut off the first supply line in response to the monitoring unit detecting the first components that include a component which contaminates the sensor, and a second valve that is configured to shut off the second supply line when the monitoring unit has detected the first components.

A control method for a system which includes:
- a monitoring unit that includes a sensor to analyze components of a first gas which may include first components;
- and a pre-separation unit disposed upstream of the monitoring unit, wherein the pre-separation unit includes:

- a second supply line that supplies a second gas that includes components obtained by removing the first components from the first gas using a first separator, to the monitoring unit;
- and an automatic valve station that switches between the first supply line and the second supply line to supply to the monitoring unit;
- and a control module configured to control the automatic valve station,
- the control method comprising:
- periodically switching by the automatic valve station, between the first supply line and the second supply line to alternately supply the first gas and the second gas;
- and
- measuring components included in the first gas and the second gas alternately using the monitoring unit;
- shutting off the first supply line by the automatic valve station in a short time when the monitoring unit has detected the first components that contaminate the sensor;
- and
- shutting off the second supply line by the automatic valve station when the monitoring unit has detected the first components.
