Process Integration Study by American Process Inc. saves over $600,000 from annual
energy costs in Northern Pulp Pictou mill
American Process Inc. conducted a Process Integration study for Northern Pulp Pictou
mill. The study involved the development and validation of a mill wide simulation
model, an operational Pinch and thermal Pinch analysis, with the objective to identify
the short and long term opportunities for energy savings at the mill.
A mill-wide model was built using apiMAX™ and was reconciled against data for average
and steady state operating conditions of the mill. This model served as the baseline
for the Process Integration study, but it can also be used by the mill for other
purposes, such as training tool for operators and engineers, assessment of the mill
wide effect of operational changes and projects, changes in production, etc.
The operational Pinch (O-Pinch™) and the thermal Pinch analysis resulted in the
development of several practical low cost and capital heat recovery projects with
significant steam savings for the mill. The study also included a cost benefit analysis
for each of the proposed projects.
Pictou mill is already in the process of implementing some of the projects proposed
by the process integration study. Savings in the order of $100,000 per year are
already being achieved, from low cost projects. Two of the capital projects are
currently in the engineering/implementation stage, and are expected to save ~$550,000
per year. Much higher monetary savings can be achieved, if more recommendations
from the Pinch study are implemented.
