Vinyl chloride monomer production

[edit / update model]
The category at business/processes/production/petrochemical/generic/ethylenedichloride provides a methodology for calculating greenhouse gas emissions associated with the production of vinyl chloride monomer. The methodology provides two ways to calculate, based on either: (1) the quantity of ethylene feedstock inputs to the production process; or (2) the quantity of vinyl chloride monomer produced. This methodology represents the Tier 1 approach described by the IPCC Guidelines for National Greenhouse Gas Inventories (NGGIP). The data is based on integrated ethylene dichloride (EDC)/vinyl chloride monomer (VCM) plants, rather than stand alone facilities.

How to use this category

Selecting an emissions scenario

To use this category, specify the feedstock type and emission type using the feedstock and emission drill choices. The emission drill choice represents, variously, emissions associated with combustion, non-combustive venting or a combination of both of these.

Specifying activity data

Next, choose between specifying the quantity of vinyl chloride monomer produced or the quantity of feedstock consumed. To specify the quantity of vinyl chloride monomer produced, set this quantity using the mass profile item value. Alternatively, specify the quantity of feedstock using the massFeedstock profile item value. Users should note that the latter option is only valid for the 'balanced process' option given an absence of data for the other types in the IPCC source documentation.

Results and calculation

The quantities returned represent the greenhouse gas emissions associated with the quantities specified. The following quantities are returned:

  • CO2: absolute quantity of CO2 emissions for the quantities specified
  • CH4: absolute quantity of CH4 emissions for the quantities specified
  • CO2e: CO2e emissions (absolute emissions converted using the appropriate global warming potential)
