The difference between ADMTPD and BDMTPD

Solution

ADMPTD is the acronym for the word \"Air dried metric ton per day\" and BDMPTD is the acronym for the word \"Bone dried metric ton per day\".

BDMPTD is the mass of the pulp flowing or being processed per day in the papermill after all the moisture has been evaporated. The pulp is repeatedly dried in an oven to reach constant mass of the pulp. Thus the moisture content in the pulp is 0. BDMPTD contains 1000kg bone dry fibre.

ADMPTD is the mas flow rate of the pulp that is internationally accepted for marketing of pulp. It is equivalent to 10% moisture content in the pulp. Thus it contains 900kg bone dry fibre and 100kg water.

Thus 1 ADMPTD = 0.9 BDMPTD
