Ethylene oxide production

[/business/processes/production/petrochemical/generic/ethyleneoxide]

The category at business/processes/production/petrochemical/generic/ethylenedichloride provides a methodology for calculating greenhouse gas emissions associated with the production of ethylene oxide. 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 ethylene oxide produced. This methodology represents the Tier 1 approach described by the IPCC Guidelines for National Greenhouse Gas Inventories (NGGIP).

How to use this category

Selecting an emissions scenario

To use this category, specify the process type and catalyst selectivity type using the process and catalystSelectivity drill choices, and specify whether methane flaring is practised using the methaneFlared drill choice. In the absence of specific data regarding catalyst selectivity, default choices are 70 for the air process and 75 for oxygen process. The default approach also assumes no flaring of methane.

Specifying activity data

Next, choose between specifying the quantity of ethylene oxide produced or the quantity of feedstock consumed. To specify the quantity of ethylene oxide produced, set this quantity using the mass profile item value. Alternatively, specify the quantity of feedstock using the massFeedstock profile item value.

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)
