Papier Masson Ltée, Masson Angers, Quebec, Canada, has set a new world TMP production record in seventy-two hour run by producing 2277 BDMT of newsprint grade TMP pulp on a single line of two-stage RGP 82 CD refiners from Metso Paper. According to André Legault, Vice-President of Operations and General Manager, the mill ran at this rate for three consecutive days beginning March 27, 2001.

During the seventy-two hour record run plant availability was more than 99.5% with only three short production interruptions. Peak operating rate on the main line was 760 BDMTPD which makes the Papier Masson TMP line the largest single line production unit in the world.

Papier Masson has only a single newsprint machine which, during the three day record run, produced 2081 tonnes of high quality newsprint using 100% TMP.

Papier Masson's TMP plant also includes an RGP 82 CD reject refiner. All three refiners in the TMP plant are connected to 32 Megawatt (43000 HP) high voltage main motors.

The TMP plant was delivered by Metso Paper and started up summer 2000.
