Flare Gas

Easily Measure Total Sulfur in Flare Gas Applications

Fast On-Line Total Sulfur Analyzers for Flare Gas

The FGA-1000™ is an online process analyzer utilizing patented Excimer UV Fluorescence (EUVF) Technology to measure total sulfur in a variety of applications such as monitoring refinery flare gas and subsequent sulfur dioxide (SO2) emissions as mandated by the EPA Rule 40 CFR 60, Subpart Ja.

The FGA-1000 has the highest dynamic measurement range of any commercially available analyzer, requiring only a single point calibration without the need for additional sample valves, calibration gases or system hardware.  It provides complete TRS Data resulting in the total analysis of all sulfur compounds potentially present in flare gas streams, not just the analysis of a few selected sulfur compounds as with GC-type applications.

Certification or CGA (Cylinder Gas Audit) is seamlessly provided by the incorporated calibration switching configuration and corresponding software menus for easy compliance testing. In addition, the FGA-1000 does not require installation in an enclosed shelter.

BENEFITS

  • Single calibration range (0-100%)
  • Unmatched speed of analysis and response time
  • Low utility consumption
  • Lowest cost of operation
  • Most compact footprint
  • Does not require installation in shelter

SEAMLESS Flare Gas Monitoring

During chemical processing, flaring is required for safety reasons. Extracting and processing oil and gas involves dealing with exceptionally high, and changeable, pressures. During crude oil extraction, a sudden or dramatic increase in pressure could cause an explosion. Industrial accidents involving oil and gas, though rare, can result in destructive, dangerous, and long-lasting fires that are difficult to contain and control. 

Flare Gas Compliance

The FGA-1000 can help you be in compliance for Subpart Ja for refinery flare gas and subsequent sulfur dioxide emissions compliance.  

  • Ensure compliance with real-time flare control
  • Ensure combustion efficiency
  • Field-proven technologies with extensive installed base
  • Unparalleled support from global Sales and Service network

APPLICATIONS 

  • Process Streams
  • Flare Gas
  • Stack Gas
  • Refined Fuels
  • LPG
  • Natural Gas

Simplified Design & Improved Reliability

Calibration and validation routines are seamlessly incorporated into our operation software. The analyzer has a very fast response time to process changes (within 1 cycle), ensuring proper process monitoring with fast-moving processes. The sample injection system design is simplified resulting in greater reliability and lower maintenance, for example, the sample valve only actuates once per cycle increasing lifetime. Finally, the analyzer results are insensitive to sample buildup or interference from oxygenates present in the sample stream.  Major system control elements are also incorporated in this home screen. The calibrate menu allows complete control of calibration and validation processes, including manual, auto calibration, and validation sequencing. Analytical results acquired during these events may be inspected at any time prior to subsequent calibrations. 

Graphical User Interface (GUI)

The SLA software incorporates a user-friendly Graphical User Interface (GUI) designed to be both intuitive and easy to use.  All aspects of analyzer operation are accessible from the Main toolbar utilizing drop-down menu screens. The home screen displays 3 user selectable digital readout and analog bar graphs updated in real-time from the analysis.

Principle of Operation

The UV Fluorescence method is the most simple and practical low-level sulfur analytical technique. It has been widely used and proven over many years of use in industrial settings. This method involves the injection of a sample into a high-temperature oxidation furnace, converting all hydrocarbons into water (H20) and carbon dioxide (C02).  Total sulfur contained in molecular-bound hydrocarbon species is oxidized at temperatures in excess of 1000°C into sulfur dioxide (S02) by the reaction:   R-SH + O2 → SO2 + CO2 + H2O

The furnace effluent containing these combustion byproducts is directed into a detection chamber where it is excited by high-energy, short-wavelength emission from the excimer source. The UV photons from the excitation source, transfer energy into the SO2molecule and raise its energy level to create back to their lower energy ground state releasing the absorbed energy as a secondary emission known as fluorescence:   SO2 + hv → SO2* → SO2 + hv’

Fluorescence emission is optically filtered to remove undesired wavelengths from excitation source and background scatter within the detector chamber. Detection of filtered fluorescence emission is accomplished using a Photomultiplier Tube and amplified by proprietary high sensitivity electronics.
