  1. YAML changes

Yaml migration​

1. Changes to VENTING_EMITTERS​

  • Introducing VENTING_EMITTERS TYPE
  • Two types can be defined in TYPE: DIRECT_EMISSION and OIL_VOLUME
  • For the DIRECT_EMISSION type the following should be specified:
    • EMISSIONS (EMISSION is deprecated): Multiple emissions can be specified, each defined by NAME and RATE
  • For the OIL_VOLUME type the following should be specified:
    • VOLUME: The oil volume/rate associated with loading/storage are defined using RATE. Multiple emissions are specified using the EMISSIONS keyword. Each emission is defined by NAME and EMISSION_FACTOR. The emission factor is used to calculate emissions as a fraction of oil loading/storage volumes.

Previously, the format looked like this:

VENTING_EMITTERS:
  - NAME: <emitter name>
    CATEGORY: <category>
    EMISSION:
      NAME: <emission name>
      RATE:
        VALUE: <emission rate>
        UNIT: <emission rate unit, default kg/d>
        TYPE: <emission rate type, default STREAM_DAY>

The new valid definition of VENTING_EMITTERS in the yaml is now, for type DIRECT_EMISSION:

VENTING_EMITTERS:
  - NAME: <emitter name>
    CATEGORY: <category>
    TYPE: DIRECT_EMISSION
    EMISSIONS:
      - NAME: <emission name 1>
        RATE:
          VALUE: <emission rate 1>
          UNIT: <emission rate unit, default kg/d>
          TYPE: <emission rate type, default STREAM_DAY>
      - NAME: <emission name 2>
        RATE:
          VALUE: <emission rate 2>
          UNIT: <emission rate unit, default kg/d>
          TYPE: <emission rate type, default STREAM_DAY>

The new valid definition of VENTING_EMITTERS in the yaml is now, for type OIL_VOLUME:

VENTING_EMITTERS:
  - NAME: <emitter name>
    CATEGORY: <category>
    TYPE: OIL_VOLUME
    VOLUME:
      RATE:
        VALUE: <oil loading/storage volume rate>
        UNIT: <volume rate unit, default kg/d>
        TYPE: <rate type, default STREAM_DAY>
      EMISSIONS:
        - NAME: <emission name 1>
          EMISSION_FACTOR: <volume to emission factor 1>
        - NAME: <emission name 2>
          EMISSION_FACTOR: <volume to emission factor 2>

Example with the new yaml-definition of VENTING_EMITTERS, for DIRECT_EMISSION type:

VENTING_EMITTERS:
  - NAME: SomeVentingEmitter
    CATEGORY: COLD-VENTING-FUGITIVE
    TYPE: DIRECT_EMISSION
    EMISSIONS:
      - NAME: CO2
        RATE:
          VALUE: 2
          UNIT: kg/d
          TYPE: STREAM_DAY
      - NAME: CH4
        RATE:
          VALUE: 4
          UNIT: kg/d
          TYPE: STREAM_DAY
