Yokogawa
Gas chromatography is a common analysis tool employed in many areas of the process control industry, including oil and gas, pharmaceutical, chemical, and others. Yokogawa Corporation of America developed instrumentation to provide top tier GC performance with their GC8000 Process Gas Chromatograph for use in oil and gas, and other industrial applications.

In addition to the ruggedness and reliability for which Yokogawa gas chromatographs are well known, the GC8000 brings a number of innovations and improvements to the company’s process gas chromatography product offering.
  • Color touchscreen HMI for easy operation
  • Advanced predictive diagnostics and software functions monitor key performance indicators during each analysis to verify analyzer is operating within proper tolerances.
  • Parallel chromatography enabled through the use of GC Modules provided as part of the GC8000. Virtual GCs can be set up inside a single GC with GC Modules to measure multiple streams simultaneously.
The graphics below expand on this overview of the GC8000 Process Gas Chromatograph, the culmination of Yokogawa’s 55 years of experience in the field. For more detailed information, or to discuss your application specifics, contact a product specialist.

Process Analyitcal Measurement - Moisture Control In Sample Gas

Sample Gas Dryer
Perma Pure
Sample gas used for analysis in process control operations will often need some conditioning in order to accommodate the input needs of the analyzer. A common requirement is to maintain a certain moisture content in the gas sample, requiring either addition or removal of moisture from the sample stream.

It is advantageous, even necessary, that any conditioning done to the sample gas have no impact on the component(s) subject to analysis. One technology provides for specific removal or addition of moisture (water) in a simple fashion, with no impact on other sample constituents.

Perma Pure gas sample dryers and humidifiers use Nafion® tubing, with a selectively permeable membrane that permits only the passage of water molecules. By controlling relative vapor pressure around the exterior of the tube, moisture can be drawn from, or added to, the sample gas stream. The simple device employs no moving parts and the vapor pressure differential is easily achieved using shop instrument air or other sources readily available.

Share your gas analysis challenges and requirements with product application experts, combining your process knowledge with their product expertise to develop effective solutions.

Accurate Measurement of Low Flow In Compressed Air Systems

Plant operators are well aware of the cost associated with continuous delivery of compressed air, a useful medium utilized as an energy source. Large or multiple compressors consume considerable amounts of electric power maintaining system pressure and flow requirements. With extensive piping and countless fittings, there are many potential points of leakage. Scheduling of various production operations can vary the demand for compressed air significantly. Getting control of your compressed air system and reducing operating cost is a noble goal. One of the primary tools needed to manage energy costs will be accurate and reliable flow measurement equipment. Here are some characteristics of flow measurement instrumentation that should prove advantageous:
Portable ultrasonic flow meter with clamp on transducer
Portable Ultrasonic Flow Measurement Instrument
Flexim

  • Non-invasive measurement from the outer pipe wall that does not add potential leak sources or pressure drop.
  • Availability in fixed or portable configuration.
  • Highly accurate, with paired temperature compensated traceable calibrated transducers
  • Installed without disturbance to piping.
  • Bidirectional measurement
  • Rugged instrument design suitable for any kind of industrial environment
Ultrasonic flow measurement technology can provide all of these characteristics, providing information that enables the operator to make fact based decisions about system design, management, and maintenance. Learn more about how ultrasonic flow meters specifically configured for compressed air system application can help you start reducing your operating cost and developing a higher level of control over your compressed air system.
