摘要:
A gas blowing cellulose pulp dryer (1) is operative for drying a web (14) of cellulose pulp by means of gas supplied from gas outlets (24) of blow boxes (22, 26) of a first drying section (5). The cellulose pulp dryer (1) comprises an inspection device (52, 152) having at least a first radiation sensor (35, 135) arranged to detect reflected radiation at the first drying section (5) to detect at least one of a position of the web (14) during operation of the dryer (1), and the occurrence of any residue (48) of the web (14).
摘要:
A reactor apparatus including: an internal mixing chamber including a first chamber section having a cross-sectional area expanding from a biomass inlet to the internal mixing chamber to the a second chamber section; the second chamber section having a substantially uniform internal cross-sectional area from the opposite end of the first chamber section to a discharge end of the mixing chamber; the biomass inlet is coupled to a source of pre-treated biomass external to the reactor vessel, and a rotating mixing device in the internal mixing chamber and coaxial with an axis of the first chamber section.
摘要:
Methods of producing mechanical pulps from lignocellulosic material including partial defibration of lignocellulosic material in a chip press followed by liquid impregnation, preheating the lignocellulosic material for 20 seconds or less at a pressure between 7.5 and 12 bar (gauge) prior to mechanically refining the lignocellulosic material in a primary mechanical refiner at a pressure between 7.5 and 12 bar (gauge), thus obtaining a high freeness pulp.
