Dried samples of extractive-free aspen wood and grinded and oven-dried BCTMP
pulp of aspen were used in experiments.
Although some of the BCTMP
and 1 mm Rayon fibre data points deviate slightly from the curve, the new parameter
mill is substantially less demanding on the environment than a traditional kraft mill as BCTMP
technology relies more on mechanical means to convert wood into pulp rather than on chemical means.
Production costs from this zero-liquid-effluent-discharge pulp mill are comparable with those of conventional BCTMP
It is made of a blend of two kinds of wood pulps--a combination of oxygen cleansed and chlorine dioxide processed and BCTMP
whitened with hydrogen peroxide.
From Table 4 it can be seen that Aspen BCTMP
gave similar results to wood flour composites.
Initial design capacity of the BCTMP
plant is 725 adt/d.
Estonian Pulp (a Norwegian/Estonian joint venture) and the regional government have plans to build a greenfield BCTMP
in Northwestern Russia.
The mill's capacity is 300,000 metric tons/yr of high-quality BCTMP
, which will be used in M-real's fine paper and paperboard mills.
The Taylor mill's productivity was slightly below target in the quarter, mainly due to a fire on the slab press that caused 400 tonnes of lost production and a BCTMP
market-related shutdown over the Christmas period.
He publishes the Market Pulp Monitor every month and has co-authored a multi-client report on BCTMP
The Taylor BCTMP
mill completed their annual outage in September and installed new dryer gas nozzles, which are resulting in improved gas usage and increased dryer capacity.
