Greenhouse Gas Reporting Program (GHGRP)

GHGRP 2012: Chemicals

The chemical manufacturing sector consists of facilities that manufacture organic or inorganic chemicals. For this summary, the sector is broken down into facilities that produce fluorinated chemicals and non-fluorinated chemicals. The non-fluorinated chemicals subsector comprises facilities that produce adipic acid, ammonia, hydrogen (both merchant and non-merchant plants), nitric acid, petrochemicals, phosphoric acid, silicon carbide, and titanium dioxide. The fluorinated chemicals subsector comprises facilities that produce HCFC-22 (and destroy HFC-23) and other fluorinated chemicals. A more detailed description of these subsectors is provided below. A total of 463 chemicals facilities reported in 2012.

Chemicals (Non-fluorinated)

The chemical manufacturing sector consists of facilities that produce adipic acid, ammonia, hydrogen (both merchant and non-merchant plants), nitric acid, petrochemicals (i.e., acrylonitrile, carbon black, ethylene, ethylene dichloride, ethylene oxide, methanol), 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 442 facilities reported 2012 emissions 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; this sector includes the CO2 from those process emissions. 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).

Fluorinated Chemicals

The fluorinated chemical subsector includes facilities that produce hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF6), nitrogen trifluoride (NF3), other fluorinated GHGs such as fluorinated ethers, and chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), including chlorodifluoromethane (HCFC-22). The category also includes facilities that destroy HFC-23, which is a by-product of HCFC-22 production and which may be emitted from the destruction process.
