SYSTEM OVERVIEW

The Octamatic Octane Analyzer Systems are based on the Falling Level Method of measuring octane rating in fuel. This is a variant of the standard Bracketing Method (Procedure B) used by laboratories and refineries.

 

Determination of the proper fuel air ratio is far more accurate than that obtained by manual methods. Unlike manual methods, the operator is out of the control loop which determines peak fuel / air ratio. Errors in recording, transcribing and calculating octane numbers are eliminated.

 

There are two versions of the ESD Octamatic Analyzer: The ON-LINE SYSTEM and the LABORATORY SYSTEM. Both systems use the same high precision methods as decribed in ASTM D2699, ASTM D2700 and ASTM D2885.

 

Economy

One computer (plus one backup computer for on-line systems) can be used for the entire test lab. Incremental costs for additional engines beyond the first engine are small. The database generated by the system is tailored to each installation, at no additional charge. Reports are also customized and can be displayed, printed or sent to other systems. Data is stored permanently and can be transmitted to removable media, remote computer systems and/or networks.

 

The ability to produce consistently at a specific octane number is extremely critical. The value of an octane barrel makes controlled production capability a moneymaker, not an expense. As competitive pressures mount and consumption declines, the need to make octane qualities of fuels as near to "zero giveaway" as possible increases significantly.

 

Whatever octane determination method is used, ESD analyzers enable the on-line blending and laboratory testing of octane quality to move into an area of precision that insures minimum of octane giveaway.

 

Lower operating and maintenance costs are also realized.

 

Ease of Operation

Operators with previous experience on CFR engines quickly adapt to these new analyzers. The ESD "Falling Level" Octane Analyzer Systems are being utilized by many refineries and testing laboratories, because of the short amount of time it takes a technician to become proficient in producing quality octane numbers.

 

In laboratories where it is required that many individuals produce octane ratings, the ESD "Falling Level" Systems bring their "site precision" close to the "method repeatability", as cited in the applicable ASTM Standards.

 

The population of experienced technicians in the field of octane ratings is on a worldwide decline. Some have turned to spectroscopy to bridge this gap only to find that you must have precise octane data to make the spectroscopy models work. These models must be maintained due to the nature of the complexity of motor gasoline. With an ESD Octane Analyzer System installed on a well maintained CFR test engine, you will have the real octane number, not a guess.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

feature & BENEFITS

GENERAL:
  • Economical with a fast payback on investment. Can run tests on multiple engines simultaneously and the system precision reduces octane "giveaway".
  • Is compliant with ASTM Standards: D2699 Research Method, D2700 Motor Method and D2885 Test Method for Determining Octane Number of Spark-Ignition Fuels by On-Line Direct Comparison Techniques.
  • Very precise system eliminating manual data calculation and recording. Frees operator from continually adjusting fuel / air ratio.
  • Always finds the fuel / air mixture resulting in maximum engine knock. Fuel / air ratio is adjusted automatically by the falling level of the fuel bowl.
  • Features a UNIX operating system insuring a cost effective capability that is stable, reliable and expandable.
  • Far superior testing of octane than manual means.
  • Minimizes operator transcription errors (all data is handled by computer).
  • Runs test on multiple engines simultaneously. ESD has installed systems with up to 14 engines.
  • With properly maintained engines, a standard deviation of 0.06 (RON) and 0.08 (MON) can be reasonably expected.
  • Includes automatic temperature control based on digital temperature input monitoring for air intake and mixture temperatures for all engines.
  • No moving parts, increasing reliability.
  • Minimal maintenance; can be accomplished by in-house personnel.
  • Water-cooled aluminum block brings fuel temperature down to ASTM requirements.
  • Top cover on bowl reduces evaporative losses.
  • Delivers customized hardware and software.
  • Comprehensive report generation.
  • ENGINE PARAMETERS / ALARMS & WARNING LIMITS.
 SOFTWARE & PROGRAMMING:
  • An interactive screen program through which the operator, at the engine, enters the variables of the blend to be analyzed, i.e. type of fuel to be made, and the blend size. All other factors are stored in the system and can only be changed under a supervisory menu. Examples: proto fuel to be used, blend name or sample ID. This reduces the probability that the operator will enter something in error.
  • A menu which lists the supervisory programs. These include, but are not limited to, features that are not normally available to the operator, such as performing spread calibration, proto rating, ASTM qualification, NEG rating, proto tank record maintenance, system parameter settings, system calibrations, records management, and running historical reports (ASTM checkout, proto rating, blend files, spread cal runs, NEG history, SQC history). The system keeps a complete history of all activities listed above that have been performed since installation.
  • Application programs written in DecisionPlus and C++ to operate the system at each engine.
  • A continuously running scanner program to read all the analog and digital signals at high speed. A moving average is maintained on all variables, resulting in precise, noise- free data acquisition.
HARDWARE:
  • 300 gigabyte RAID hard drives for program and data reliability.
  • Includes UNIX operating system for high reliability, reduced costs and ease of expansion.
  • Color printer for reports.
  • Uninterruptible power supply for entire system.
ENGINEERING & INSTALLATION:
  • Professional installation and startup will be performed by Electronic Systems Design field engineer(s). Optionally, a software engineer may also be on-site, if needed, during startup and commissioning (this will be determined on a site-by-site basis).
  • Operator and supervisory training is included, which will be done during the installation phase. Our policy is to stay on-site until the project is complete and the customer is satisfied that all training has been done and everything is working properly. If there is a problem during the first twelve (12) months that your staff cannot resolve, we will make a return trip at no charge.
