ASTM D7097 Thermo-Oxidation Engine Oil Simulation Tester
KN-7097 Thermo-Oxidation Engine Oil Simulation Tester conforms to ASTM D7097 Standard Test Method for Determination of Moderately High Temperature Piston Deposits by Thermo-Oxidation Engine Oil Simulation Test—TEOST MHT and ASTM D6355 Standard Test Method for Determination of High Temperature Deposits by Thermo-Oxidation Engine Oil Simulation Test. Deposit-forming tendencies of an engine oil under oxidative conditions are determined by circulating an oil-catalyst mixture comprising a small sample of the oil and a very small (0.1g) amount of an organo-metallic catalyst. This sample mixture is then circulated for exactly 24h in the TEOST MHT instrument over a special wire-wound depositor rod heated by electrical current to a controlled temperature of 285℃ at the hottest location on the rod. The depositor rod is weighed before and after the test and any deposit formation on the rod as well as any deposits collected from rod washings are determined. During the test, precisely controlled and directed air is caused to bathe the oil flowing down the depositor rod and, thereby, to provide opportunity for oxidation. Precision of the test is strongly influenced by the care in manufacture of the wire-wound steel depositor rods and the treatment of the coating of the wound wire, the rate of air flow, and the amount and degree of mixing of the catalyst.

Apparatus for Chlorine in Aromatics
KN-7536 Apparatus for Chlorine in Aromatics conforms to ASTM D7536 Standard Test Method for Chlorine in Aromatics by Monochromatic Wavelength Dispersive X-ray Fluorescence Spectrometry. This test method provides for the precise measurement of the chlorine content of aromatics with minimal sample preparation and analyst involvement. The typical time for each analysis is five or ten minutes. Knowledge of the chlorine content of aromatics is important for process control as well as the prediction and control of operational problems such as unit corrosion and catalyst poisoning, and in the blending of products to commodity specifications. Various federal, state, and local agencies regulate the chlorine content of some petroleum products, including aromatics. Unbiased and precise determination of chlorine in aromatics is critical to compliance with regulatory standards.
