CVR Partners LP, Sugar Land, Texas, said on Oct. 5 its subsidiary, Coffeyville Resources Nitrogen Fertilizers LLC (CRNF), has generated its first carbon offset credits related to the company’s voluntary nitrous oxide (N2O) abatement efforts at its Coffeyville, Kan., nitrogen fertilizer plant. CVR has utilized similar technology to abate N2O at its East Dubuque, Ill., nitrogen fertilizer plant since 2011.
CRNF previously entered into a Joint Development Agreement with ClimeCo, a developer of emission-reduction projects for nitric acid plants, to jointly design, install, and operate a tertiary abatement system at one of its nitric acid plants in Coffeyville. The system was designed to abate 94 percent of all N2O in the unit while preventing the release of approximately 450,000 mt of carbon dioxide equivalent (CO2e) on an annualized basis.
CVR said N2O abatement systems at East Dubuque’s two nitric acid plants have abated, on average, the annual release of approximately 233,000 mt of CO2e during the past five years. With the Coffeyville system now operating at design capacity, CVR said its two fertilizer facilities should abate more than 1 million mt of CO2e each year, in combination with the Coffeyville facility’s carbon dioxide (CO2 ) sequestration efforts.
“As a leader in the production of environmentally friendly ‘green’ nitrogen fertilizer, CVR Partners is proud to have generated its first carbon offset credits as a result of our voluntary nitrous oxide abatement project in Coffeyville, Kan.,” said Mark Pytosh, CVR CEO. “Coupled with our Coffeyville CO2 sequestration efforts, this facility is uniquely qualified to produce hydrogen and ammonia that is certified ‘blue’ to a market that is increasingly demanding reduced carbon footprints.”
