  • Sulfur Tail Gas and Air Demand
  • Fourier Transform Near Infrared
  • Water Hardness
  • NOx/SOx and other Ultraviolet methods
  • Opacity for furnace stack gas measurements
  • As new capital projects are developed, the AMT is responsible to follow the design progress on the technologies they support to ensure that features required for equipment maintainability are included in the base scope of the project prior to final project approval.
  • Technology support responsibilities will be periodically rebalanced among the Analyzer Technologist staff group, and the AMT may become responsible for any of the following online analyzer measurement types and categories:

  • The AMT is frequently required to inspect installations in the field to verify proper operation, audit the effectiveness of routine maintenance practices, identify poor equipment reliability, performance or accuracy, and assist the Production departments with urgent repairs.
  • The AMT maintains a log of repeat analyzer problems known as a Bad Actor List.
  • The AMT is responsible to set criteria for detecting unusual or unacceptable failure rates, and create plans to address such problems
  • The AMT periodically reviews and updates site analyzer maintenance procedures and work instructions.

Custody Transfer Measurement


  • The AMT is the site subject matter expert on custody transfer measurement (CTM) applications.
  • The AMT must be familiar with the refinery's contractual terms for material receipts and deliveries.
