Abstract
Method and control system are provided for controlling values of process parameters of a pretreatment process of wood particles. A sampler is used to obtain a sample of a product flow of said pretreatment process after said wood particles have undergone steam explosion in a hemihydrolysis reactor. A particle measurement device is used to measure one or more characteristics of particles in said sample and to produce one or more pieces of measurement information indicative of the measured characteristics. Said one or more pieces of measurement information are used to select one or more values of one or more of said process parameters.
