mass balance around a typical flowsheet for producing one oven dry tonne of pulp. The calculations start at the outlet of the white liquor clarifier by determining the flow of white liquor needed at the digester plus any white liquor required by the pulp mill bleach plant and then calculating the lime required to make that quantity of white liquor.
The fiber from nearly any plant or tree can be used for paper. However, the strength and quality of fiber, and other factors that can complicate the pulping process, varies among tree species. In general, the softwoods e.g., pines, firs, and spruces yield long and strong fibers that impart strength to paper and are used for boxes and packaging.
The gas-phase polymerization is economical and flexible and can accommodate a large variety of catalysts. It is the most common technology in modern polypropylene production plants. Relevant technologies are Novolen , Unipol gas-phase processes, Borstar
A good plant design can minimize capital expenditure and maximize on long term profits. A good plant design together with careful planning and execution of the startup can greatly contribute towards o easing commissioning problems, and o can ensure the plant brought into production in time.
