GHGRP 2011: Chemicals
The chemical manufacturing sector consists of facilities that produce adipic acid, ammonia, HCFC-22 (and destroy HFC-23), hydrogen (both merchant and non-merchant plants), nitric acid, petrochemicals (i.e., acrylonitrile, carbon black, ethylene, ethylene dichloride, ethylene oxide, methanol), fluorinated gases, phosphoric acid, silicon carbide, soda ash, and titanium dioxide. Besides the emissions from these chemical production processes, the sector includes combustion emissions from facilities that produce pesticides, fertilizer, pharmaceuticals, and other organic and inorganic chemicals. A total of 458 facilities reported under this sector. A small number of facilities in this sector collect CO2 either for use in their other production processes, to transfer to other users, or to sequester or otherwise inject underground, and, process emissions reported under this sector includes this CO2. For example, some of the process emissions reported for ammonia manufacturing plants includes CO2 that is later consumed on site for urea production. This CO2 is not released to the ambient air from the ammonia manufacturing process unit(s).
- Total Reported Direct Emissions from Chemicals, by Subsector (as of 1/16/13).
- Location and emissions range for each reporting facility in the chemical manufacturing sector (as of 1/16/13).
This map shows the locations of direct-emitting facilities. The size of a circle corresponds to the quantity of emissions reported by that facility.
|Chemicals Sector — Greenhouse Gas Emissions Reported to the GHGRP
(all emissions values presented in million metric tons CO2e unless otherwise noted)
|Number of facilities:||458||449|
|Total emissions (CO2e):||180||166|
|Emissions by greenhouse gas (CO2e)|
|• Carbon dioxide (CO2):||145||149|
|• Methane (CH4):||**||**|
|• Nitrous oxide (N2O):||22||17|
|• Hydrofluorocarbons (HFCs):||7||6|
|Subpart L emissions||6||NR|
- NR means that this value was not reported for the 2010 reporting year.
- ** Total reported emissions are less than 0.5 million metric tons CO2e.
Process emissions from the production of fluorinated gases were reported in 2011 but not in 2010. These emissions are included in the table above. Total emissions from this source category in 2011 were 6.6 MMT CO2e.
CO2 emissions from the combustion of biomass are NOT included in emissions totals provided above.
