K-Patents Process Refractometers for Metal Machining and Mining Industries

K-Patents provides Process Refractometers for accurate in-line concentration and Brix measurements of water based hydraulic fluids. These are e.g. quenchants, cooling lubricants, cutting oils and coating fluids in the metal machining operations and hydraulic emulsions (longwall emulsions) in the longwall coal mining. Alumina mining and refining operations can also be improved by monitoring the concentration of caustic soda that is used to dissolve alumina. The purpose is to keep the concentration of hydraulic fluids or caustic constant while minimizing the use of fresh fluid or chemical. Fluid can be lost in the hydraulic circuit at extremely large rates. Unlike periodical sampling, continuous monitoring provides instant feedback as to changes in the fluid and to precise dosing and mixing of the fresh fluid.

K-Patents Process Refractometers for Semiconductor Industry

K-Patents provides Process Refractometers for real-time concentration monitoring in wet chemical process applications in the semiconductor and microelectronics fabrication. K-Patents Semicon Process Refractometer is an all purpose transmitter, in the sense that the same instrument can be used to monitor all kinds of liquid chemicals.

K-Patents Semicon Refractometer is designed to be used in bulk chemical distribution, mixing, blending and dilution, and in point-of-use in the fab. The key control function is to monitor and to provide an alarm, if the chemical is out of specifications. This prevents wrong chemicals or wrong concentrations from being dispensed on to the process and thus helps avoiding very costly production problems.

K-Patents Process Refractometers for Sugar Industry

K-Patents provides Process Refractometers for accurate in-line Brix and concentration measurements in the cane and beet sugar refining and milling processes. The purpose is to achieve high quality liquid and crystal sugars and to minimise costs of production. K-Patents refractometers are used:

• to optimise extraction process and to minimize usage of water that needs to be removed from sugar juice later at the evaporator stage.
• to adapt product flow to the capacity of the evaporators in order to save energy.
• to make sure that liquid bulk sugar and molasses meet specifications.
• to control feed juice to adjust the concentration with the capacity of the separation columns. This leads to longer intervals between recovering cycles and longer lifetime of the columns.
• to monitor supersaturation over complete strike of crystallization.
• to implement automatic and accurate seeding of the vacuum pan.
