K-Patents has released a new application note on Ammonia Removal in Water Treatment. Ammonia can be present in underground water as an impurity. It is undesirable in water because ultimately it gets converted into nitrites and nitrates which cause lack of vitamin and if combined with other components can cause cancer. Moreover, elevated ammonia concentration can create favourable conditions for intensive growth of aquatic organisms, including algae, which leads to deterioration of commodity water quality. Ammonia is stripped away from the process by turning it into ammonium sulfate. K-Patents refractometer PR-23-M is measuring the ammonium sulfate concentration in-line. If the value is correct, ammonium sulfate can be stored for further use, if not, the product is further recycled.

K-Patents has released a new application note on Pure Water Treatment by Chemical Precipitation. Pure water treatment is the process of removing undesirable chemicals, biological contaminants, suspended solids and gases from raw water. The purified water is then stored for human consumption, medical, pharmacological, chemical or industrial needs. Water treatment by chemical precipitation is a complex process. It starts with adding flocculants, specifically, Polyaluminium Chloride (PACl) and Sodium Hydroxide (NaOH) into raw water. PACl precipitates in big volumetric flocs which absorb suspended pollutants in the raw water. In order to keep the flocculation process smooth, PACl concentration must be constantly monitored which is possible with K-Patents’ refractometer.

K-Patents has released a new application note on Chewing gum coating. Confectionery coating plays a decisive role in the final product’s appearance and functionality. Fine coating has effect on the flavour and the quality of confectionery products such as the chewing gum. Preparation of syrup for chewing gum coating starts with adding syrup components, in particular, sugar or its substitutes, e.g. maltose, and water to the mixing tank. The exact syrup concentration is critical to secure the correct flavour and gums not sticking together in the coating machine (drum).

K-Patents has released a new application note on Polyphenylene Sulfide (PPS) Resin Process. PPS resin is a form of engineering plastic widely used as a material for automobile and electronic parts due to its outstanding properties. PPS resin is made from sodium sulfide and dichlorobenzene in a polar solvent. The process medium is the suspension containing PPS and sodium chloride (NaCl). If chloride and sodium from raw materials remain in the resin, they can lead to the corrosion of molds and functional deterioration of metal parts. The K-Patents Process Refractometer PR-23-GP measures the NaCl concentration. It also monitors and controls the NaCl dissolved solids concentration without influence of the undissolved PPS resin.

K-Patents has released a new application note on Linquid hydrocarbon identification in transportation operation. Chemical plants and refineries receive or deliver many different liquid hydrocarbons, including NGLs which are transported via pipeline, railcar, tanker trucks and/or ship. Many of these products are very similar in properties and appearance, therefore, proper identification or interface detection of these hydrocarbons at transport locations that handle multiple products is important to ensure good quality assurance.
