  • eCalc version 9.17: the optional keyword CONDITION and CONDITIONS can be used to define conditions that affect the RATE.
  • eCalc version 8.13: Updated definition of VENTING_EMITTERS. New mandatory keyword TYPE is defining the venting emitter type. Based on the selected type, the new keywords EMISSIONS (TYPE: DIRECT_EMISSION) or VOLUME (TYPE: OIL_VOLUME) should be specified.
  • eCalc version 8.8: Updated definition of VENTING_EMITTERS. New keyword EMISSION is replacing EMITTER_MODEL and EMISSION_NAME. Now possible to define UNIT and TYPE for emission rate.
  • eCalc version 8.7: VENTING_EMITTERS keyword is replacing the DIRECT_EMITTERS keyword.
  • eCalc version 8.6 and earlier: Use DIRECT_EMITTERS as before.

eCalc version 8.7 and before: Description​

The VENTING_EMITTERS keyword covers the direct emissions on the installation that are not consuming energy. The attributes NAME, EMISSION_NAME, CATEGORY and EMITTER_MODEL are required.

Format​

VENTING_EMITTERS:
  - NAME: <emitter name>
    EMISSION_NAME: <emission name>
    CATEGORY: <category>
    EMITTER_MODEL: <emitter model>

Example​

VENTING_EMITTERS:
  - NAME: SomeVentingEmitter
    EMISSION_NAME: CH4
    CATEGORY: COLD-VENTING-FUGITIVE
    EMITTER_MODEL:
      <emitter model data>
  ...
  - NAME: SomeOtherVentingEmitter
    EMISSION_NAME: C2H6
    CATEGORY: COLD-VENTING-FUGITIVE
    EMITTER_MODEL:
      <emitter model data>

eCalc from version 8.8: Description​

The attributes NAME, CATEGORY and EMISSION are required.

Format​

VENTING_EMITTERS:
  - NAME: <emitter name>
    CATEGORY: <category>
    EMISSION:
      <emission data>

Example​

VENTING_EMITTERS:
  - NAME: SomeVentingEmitter
    CATEGORY: COLD-VENTING-FUGITIVE

      <emission data>
  ...
  - NAME: SomeOtherVentingEmitter
    CATEGORY: COLD-VENTING-FUGITIVE
    EMISSION:
      <emission data>

eCalc from version 8.13: Description​

The keywords NAME, CATEGORY and TYPE are required. The venting emitter type can be either DIRECT_EMISSION or OIL_VOLUME.

The keywords EMISSIONS or VOLUME are required, dependent on which venting emitter type is used.

Venting emitter of TYPE DIRECT_EMISSION: Specify emission rates directly.

Format​

VENTING_EMITTERS:
  - NAME: <emitter name>
    CATEGORY: <category>
    TYPE: DIRECT_EMISSION
    EMISSIONS:
      <emission data>

Example​

VENTING_EMITTERS:
  - NAME: SomeVentingEmitter
    CATEGORY: COLD-VENTING-FUGITIVE
    TYPE: DIRECT_EMISSION
    EMISSIONS:
      - NAME: co2
        RATE:
          VALUE: 4

        RATE:
          VALUE: 2
          UNIT: KG_PER_DAY
          TYPE: STREAM_DAY

Venting emitter of TYPE OIL_VOLUME: Specify oil loading/storage volumes, and emission factors - to calculate emissions as fractions of the volume.

Format​

VENTING_EMITTERS:
  - NAME: <emitter name>
    CATEGORY: <category>
    TYPE: OIL_VOLUME
    VOLUME:
      <oil volumes/rates and emission factors>

Example​

      - NAME: ch4
        EMISSION_FACTOR: 0.02

eCalc from version 9.17: Description​

The keywords NAME, CATEGORY and TYPE are required. The venting emitter type can be either DIRECT_EMISSION or OIL_VOLUME.

The keywords EMISSIONS or VOLUME are required, dependent on which venting emitter type is used.

New Feature: CONDITION and CONDITIONS From eCalc version 9.17, the optional keyword CONDITION(S) can be used to define conditions that affect the RATE. This allows for more precise modeling of scenarios, such as when an asset is producing or not, by using time series or logical expressions.

  • Usage: CONDITION(S) can be applied under RATE for both DIRECT_EMISSION and OIL_VOLUME types.
  • Example: A condition can specify that emissions only occur when a time series value equals 1.

Format (TYPE: DIRECT_EMISSION)​
