Problems with aluminosilicate scales in pulp and paper recycle streams create an
interest in the formation mechanism and the chemical equilibrium of aluminosilicates.
Evaluating solubility data from a system containing Na⁺ CI⁻, and OH⁻ ions as well
as aluminium and silicon compounds, allowed to elucidate the characteristics of the
aluminosilicate...
In designing a solubility based separation process
for solvent recovery of an organosolv pulping process, the
phase behavior of polymeric lignin molecules in alcohol -
water mixed solvent should be known. In this study,
sodium lignin sulfonates (NaLS) samples were fractionated
into three different molecular weight fractions using a
partial...
Non-process elements are present in all kraft
recovery systems. Non-process elements are defined as
those elements which are not essential to the chemical
process, i.e., are neither active pulping chemicals (e.g.,
NaOH and Na₂S in the kraft process), nor compounds present
as a result of incomplete conversion of makeup chemicals...
Poor aqueous solubility of a large number of newly discovered chemical entities is posing a significant challenge for the formulation industry and is delaying their drug development. The number of formulation techniques available to solubilize these poorly soluble molecules is very limited. In addition to that, traditional formulation methods involve...
