The present invention relates to a method for early detection of carbonization during the drying of an organic material. The method of the present invention measures temperature variation per unit time of exhaust gas containing water (HO), carbon monoxide (CO), or carbon dioxide (CO), which are to be generated by the pyrolysis of an organic material, and the concentration of carbon monoxide/carbon dioxide of the exhaust gas, so as to determine the occurrence of carbonization therethrough, thereby enabling early detection of carbonization within a dryer.

Method for early detection of carbonization during drying of organic material

A method for controlling a residual monomer content of a polymer, wherein when a hot-air temperature and a hot-air velocity are maintained, the controlling method can predict the content of the residual monomer by controlling a hot-air mass ratio without influence of other external factors.
