Innovative Test Equipment for the Petrochemical Industry

98 Test Methods – 5 Experts – 1 Goal

API degree, acid number, base number, color, flash point, cloud point, pour point, vapor pressure, viscosity, refractive index, density, specific gravity, water content, sulfur, mercaptan, vapor-liquid ratio temperature of crude oils, lubricants, fuels … there is probably no other industry where that a wide variety of different parameters must be determined in quality control as in the petroleum industry.

As a consequence most petrochemical labs are equipped with measuring instruments from many different manufacturers. Well known suppliers specialized in petroleum testing equipment aim to cover as many applications as possible providing customers with a great variety of different analyzers.

CANNON Instruments, Eralytics, KEM, TANAKA and Zematra selected a different approach: Instead of becoming members of a group, able to cover almost the entire spectrum of petroleum applications, we decided to remain as independent specialists focusing each of us on a limited number of applications. We are convinced that our strong focus on certain technologies is the key to achieving our common goal - supplying our customers with the most advanced solutions for the applications we cover.

Since its founding in 1961, Kyoto Electronics Manufacturing (KEM) has been concentrated on developing and manufacturing analytical and measuring instruments.

KEM's offering includes four product lines which are required in almost every petrochemical laboratory:

  • Density Meters:KEM offers a wide range of of digital density meters to determine density, specific gravity, API gravity, etc. KEM is a JCSS Accredited Calibration Laboratory for Density assessed on JIS Q 17025:2000 (ISO/IEC 17025: 1999).
  • Refractometers: KEM is a leading center of innovation when it comes to digital refractometers: It was the first company which offered digital refractometers with built-in solid state thermostates.
  • Potentiometric Titrators: KEM's automatic titrators are widely used in the petrochemical industry to perform determinations of the acid and base number, the sulfur (Thiol, Mercaptane) content, etc.
  • Karl Fischer Titrators: World leading, patented technology for potentiometric and coulometric moisture determinations in petroleum products – KEM offers a wide range of Karl Fischer titrators for every need and budget, ranging from compact low cost titrators to modular, touch screen controlled high end systems capable of performing two titrations in parallel.

Tanaka Scientific Limited has been engaged in the field of scientific instruments since it was founded in 1901. Since 45 years, Tanaka has been pioneering in the development of automatic petroleum testers. Nowadays Tanaka is regarded as a leading manufacturer of automatic petroleum testers serving the worldwide petroleum market.

Tanaka has been working on the making of standards test methods for JIS (Japanese Industrial Standard) on petroleum testing as an appointed member from its beginning in 1968. Also, Tanaka has been a voting member of ASTM (American Society for Testing and Materials) since 1982 and an appointed member of ISO (International Standard Organization) TC28 domestic committee since 1983.

Due to the demand of higher productivity in petroleum testing, laboratory automation systems (LAS) have gained popularity in the industry. Tanaka chaired a study group sponsored by the Japanese Government on the development of LAS. Ever since this study Tanaka has been developing and marketing laboratory automation systems for petroleum testing.
