摘要： Pool or spa water can be monitored for dimethyl hydantoin content, as a residue of disinfection with halogenated hydantoin, by determining the quantity of base required to adjust the pH to 9.3. The pH may be judged by a suitable indicator for example thymol phthalein or thymol blue. The method can be applied either titrimetrically, or by comparison colorimetrically with standard solutions and may be modified for use in relation to other halogenated hydantoins. The method may be applied to the testing of pools for compliance with an advisory dimethyl hydantoin content limit and may be embodied in a kit for easy poolside use.

摘要： Methods for estimating the solvency potential for various chemical additives used for asphaltene deposit remediation or inhibition have been developed. These methods can be used for remediating or inhibiting asphaltene deposition in various applications including upstream production (e.g., near-wellbore, downhole, flow-lines, separators), midstream processes (e.g., pipe lines, transport, and storage), and downstream (e.g., hydrocarbon refining).

摘要： A system for measuring and controlling the concentration of a chemical agent in a solution has a reaction cell for receiving a sample, a titrant dropper for releasing one or more drops of titrant into the sample, a first photosensor for sensing disruptions of light for every drop of titrant released, and a controller that communicates with the photosensor and computes the concentration of the chemical agent based on the number of disruptions of light at the photosensor. The present invention also includes a method for sensing and controlling the concentration of a chemical agent in a solution. The method includes having a sample containing the chemical agent, triggering the release of a number of drops of titrant into the sample, detecting the number of drops released into the sample, and computing the concentration of the chemical agent in the sample based on the number of drops of titrant released into the sample.

摘要： The present invention is an improved method and related apparatus for quantitatively analyzing machine working fluids and other aqueous compositions such as wastewater which contain various mixtures of cationic, neutral, and/or anionic surfactants, soluble soaps, and the like. The method utilizes a single-phase, non-aqueous, reactive titration composition containing water insoluble bismuth nitrate dissolved in glycerol for the titration reactant. The chemical reaction of the bismuth ion and glycerol with the surfactant in the test solutions results in formation of micelles, changes in micelle size, and the formation of insoluble bismuth soaps. These soaps are quantified by physical and chemical changes in the aqueous test solution. Both classical potentiometric analysis and turbidity measurements have been used as sensing techniques to determine the quantity of surfactant present in test solutions. This method is amenable to the analysis of various types of new, in-use, dirty or decomposed surfactants and detergents. It is a quick and efficient method utilizing a single-phase reaction without needing a separate extraction from the aqueous solution. It is adaptable to automated control with simple and reliable sensing methods. The method is applicable to a variety of compositions with concentrations from about 1% to about 10% weight. It is also applicable to the analysis of waste water containing surfactants with appropriate pre-treatments for concentration.
摘要翻译：本发明是一种改进的方法和相关装置，用于定量分析机器工作流体和其它水性组合物如废水，其含有阳离子，中性和/或阴离子表面活性剂，可溶性皂等的各种混合物。该方法利用溶解在甘油中的水不溶性硝酸铋用于滴定反应物的单相非水反应性滴定组合物。在测试溶液中铋离子和甘油与表面活性剂的化学反应导致胶束的形成，胶束尺寸的变化和不溶性铋皂的形成。这些皂通过水性试验溶液中的物理和化学变化来量化。经典电位分析和浊度测量都被用作感测技术来确定测试溶液中存在的表面活性剂的量。这种方法适用于各种类型的新型，使用中，肮脏或分解的表面活性剂和洗涤剂的分析。使用单相反应而不需要从水溶液中分离萃取，这是一种快速有效的方法。它采用简单可靠的感应方式，适应于自动化控制。该方法适用于浓度为约1％至约10％重量的各种组合物。也适用于含有适当预处理浓缩的含有表面活性剂的废水的分析。
