  • Chemical Pretreatment for RO and NF
    Chemical Pretreatment For RO and NF October 2013 Lenntech [email protected] Tel. +31-152-610-900 www.lenntech.com Fax. +31-152-616-289 There are a number of chemicals that can be introduced into the RO feed to enhance the operation of the RO system. Acids Caustic Dechlorination chemicals Antiscalants and Dispersants Acids: Acids, typically hydrochloric [HCl] or sulfuric [H2SO4], are injected into the RO feed to lower pH. Sulfuric acid is used more often than HCl acid. One reason for this is because sulfuric acid is relatively lower in operating cost than HCl acid. Another advantage to using sulfuric over HCl is the reduced fuming to the atmosphere, which means less corrosion to surrounding metal components. Sulfuric acid is sometimes preferred over HCl since there is a better membrane rejection of the sulfate ion than the chloride ion. Technical grade sulfuric acid, with no other additives, is suitable for use with a RO. Sulfuric acid is commercially available as a 20% and 93% solution. The 93% solution is also referred to as “66 0 Baume solution”. Caution is required in diluting 93% sulfuric acid, since the maximum heat of dilution of about 280 F occurs around 60%. It is critical that the concentrated acid is added slowly to the top of dilution water that is being agitated to minimize the buildup of heat and boiling of the makeup solution. Hydrochloric acid is preferred when calcium sulfate, barium sulfate, or strontium sulfate scaling is a concern. Sulfuric acid increases the sulfate ion level in the RO feed, which directly increases the potential for sulfate-based scaling.

  • Mineral Scale Management Part II
    PEER-REVIEWED SCALE Mineral Scale Management Part II. Fundamental Chemistry ALAN W. RUDIE AND PETER W. HART ABSTRACT: The mineral scale that deposits in digesters and bleach plants is formed by a chemical precipitation process.As such, it is accurately modeled using the solubility product equilibrium constant. Although solubility product identifies the primary conditions that must be met for a scale problem to exist, the acid-base equilibria of the scaling anions often control where in the process scale will occur. These equilibria are the primary control method to minimize or pre­ vent scale in a bleach plant. Both the acid-base equilibria and solubility product equilibria are influenced by temper­ ature and ionic strength. This paper reviews the chemistry of precipitation and acid-base equilibria. The Gibbs free energy expression is presented as a method to estimate equilibrium constants at temperatures in the bleach plant.The effect of ionic strength on ion activity and its influence on these processes are also discussed. Application: Preventing scale problems requires an understanding of the solubility product equilibrium, the acid-base equilibrium of the scaling anion, and the effects of temperature and ion activity on these equilibria. ome pulp mills have always experi­ trations in the wood supply. Those conditions that barely exceed the Senced mineral scale buildup, but cases required more detailed equilibri­ saturation concentrations, it can this problem has increased with um modeling and will be handled in take hours or longer for an obvi­ efforts to comply with environmental the third paper of the series on non- ous precipitate to form.

  • The Interplay of Steric and Electronic Factors Affecting Geometrical Isomerism of Dtaryl Ket~M~Ne Derivatives
    Tctrahcxlron, 1960, Vol. 9, pp. 210 co 229. Pcrgamon Press Ltd. Printed in Mxthcrn Ireland THE INTERPLAY OF STERIC AND ELECTRONIC FACTORS AFFECTING GEOMETRICAL ISOMERISM OF DTARYL KET~M~NE DERIVATIVES P. A. S. SMITHand E. P. ANTONIADES* Dept. of Chemistry, University of Michigan, Ann Arbor, Michigan AbslracG-The evidence bearing on the mechanism of the Schmidt reaction with ketones is critically reexamined. It is shown that dehydration of an initially formed azid~hydrin (I) to a ketimino- di~nium ion (II), which may or may not equilibrate between its geometrj~lly isomeric forms (TIa or b), can account for the various reported ratios of isomer2 amides produced from unsymmetri~l ketones. The previously anomalous behavior of w&-substituted diary1 ketones can be resolved by taking into account the influence of conjugative effects on the preferred rotational positions. The ratios of amides produced from a series of 4.kylbenzophenones by both the Schmidt reaction and oximation pfus Beckmann r~~angement have been dete~in~ at different temperatures; there are appreciabIe differences in the product ratios and their temperature coefficients from the two reactions. IN 1948 one of us proposed’ a mechanism for the Schmidt reaction2 between hydrogen azide and ketones, which in the ensuing decade has been the basis for most discussion of the reaction. So much pertinent excremental investigation and theoretiGa1 discus- sion has since been published that a reconsideration of the overall picture seems justified at this time. ‘The principal reaction products of ketones and hydrogen azide are amides, of which a single compound is produced from symmetri~l ketones, but a pair of isomers may be produced in unequal amounts from unsymmetrical ketones.
