An exhaust gas processing system including a process chamber in which an exhaust gas is produced; an exhaust gas measurer receiving the exhaust gas and measuring a concentration of the exhaust gas; a solid producing gas processor receiving the exhaust gas and removing a solid producing gas contained in the exhaust gas; a gas supply supplying dilution and cooling gases to the solid producing gas processor; a processed gas measurer receiving, as a processed gas, the exhaust gas free of the solid producing gas and measuring a temperature of the processed gas and ingredients of the processed gas; and a controller receiving results of measurement of the concentration of the exhaust gas from the exhaust gas measurer and results of measurement of the temperature of the processed gas and the ingredients of the processed gas from the exhaust gas measurer and controlling the gas supply based on the measurement results.

Exhaust gas processing system including adsorbent for suppressing powder-like byproduct

An apparatus for collecting a by-product, includes: a chamber provided with a gas inlet and a gas outlet and having an internal space; a heater disposed on the gas inlet side of the internal space within the chamber and varying a heating temperature in time series; a vortex forming member disposed around the heater; a plurality of first collecting members disposed below the heater; a second collecting member disposed below the first collecting member so that a plurality of second collecting members intersect each other; and a third collecting member disposed on the gas outlet side of the internal space within the chamber.
