New Application Note on Polyphenylene Sulfide (PPS) Resin Process has been released

March 11, 2013

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.

New Application Note on Liquid Hydrocarbon Identification in Transportation Operation has been released

March 8, 2013

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.

Interface detection of liquid hydrocarbons using Refractive index measurement technology

January 8, 2013

A major south Texan refinery recently investigated a reliable way to distinguish between natural gasoline (trip gas) and two butanes (n-butane and iso-butane (2-methylpropane)) in its loading station. K-Patents Process Refractometer was chosen for four installation locations: one at railcar unloading station and three in the different product tank inlets.
