Section 98.473 - Calculating CO[2] received

(a) You must calculate and report the annual mass of CO₂ received by pipeline using the procedures in paragraphs (a)(1) or (a)(2) of this section and the procedures in paragraph (a)(3) of this section, if applicable.

(1) For a mass flow meter, you must calculate the total annual mass of CO₂ in a CO₂ stream received in metric tons by multiplying the mass flow by the CO₂ concentration in the flow, according to Equation UU-1 of this section. You must collect these data quarterly. Mass flow and concentration data measurements must be made in accordance with § 98.474 .

where:

CO_2T,r = Net annual mass of CO₂ received through flow meter r (metric tons).

Q_r,p = Quarterly mass flow through a receiving flow meter r in quarter p (metric tons).

S_r,p = Quarterly mass flow through a receiving flow meter r that is redelivered to another facility without being injected into your well in quarter p (metric tons).

C_CO2,p,r = Quarterly CO₂ concentration measurement in flow for flow meter r in quarter p (wt. percent CO₂, expressed as a decimal fraction).

p = Quarter of the year.

r = Receiving flow meter.

(2) For a volumetric flow meter, you must calculate the total annual mass of CO₂ in a CO₂ stream received in metric tons by multiplying the volumetric flow at standard conditions by the CO₂ concentration in the flow and the density of CO₂ at standard conditions, according to Equation UU-2 of this section. You must collect these data quarterly. Volumetric flow and concentration data measurements must be made in accordance with § 98.474 .

where:

CO_2T,r = Net annual mass of CO₂ received through flow meter r (metric tons).

Q_r,p = Quarterly volumetric flow through a receiving flow meter r in quarter p at standard conditions (standard cubic meters).

S_r,p = Quarterly volumetric flow through a receiving flow meter r that is redelivered to another facility without being injected into your well in quarter p (standard cubic meters).

D = Density of CO₂ at standard conditions (metric tons per standard cubic meter): 0.0018682.

C_CO2,p,r = Quarterly CO₂ concentration measurement in flow for flow meter r in quarter p (vol. percent CO₂, expressed as a decimal fraction).

p = Quarter of the year.

r = Receiving flow meter.

(3) If you receive CO₂ through more than one flow meter, you must sum the mass of all CO₂ received in accordance with the procedure specified in Equation UU-3 of this section.

where:

CO₂ = Total net annual mass of CO₂ received (metric tons).

CO_2T,r = Net annual mass of CO₂ received (metric tons) as calculated in Equation UU-1 or UU-2 for flow meter r.

r = Receiving flow meter.

(b) You must calculate and report the annual mass of CO₂ received in containers using the procedures specified in either paragraph (b)(1) or (b)(2) of this section.

(1) If you are measuring the mass of contents in a container under the provisions of § 98.474(a)(2)(i) , you must calculate the CO₂ received in containers using Equation UU-1 of this section.

where:

CO_2T,r = Annual mass of CO₂ received in containers r (metric tons).

C_CO2,p,r = Quarterly CO₂ concentration measurement of contents in containers r in quarter p (wt. percent CO₂, expressed as a decimal fraction).

Q_r,p = Quarterly mass of contents in containers r in quarter p (metric tons).

S_r,p = Quarterly mass of contents in containers r that is redelivered to another facility without being injected into your well in quarter p (standard cubic meters).

p = Quarter of the year.

r = Containers.

(2) If you are measuring the volume of contents in a container under the provisions of § 98.474(a)(2)(ii) , you must calculate the CO₂ received in containers using Equation UU-2 of this section.

where:

CO_2T,r = Annual mass of CO₂ received in containers r (metric tons).

C_CO2,p,r = Quarterly CO₂ concentration measurement of contents in containers r in quarter p (vol. percent CO₂, expressed as a decimal fraction).

S_r,p = Quarterly volume of contents in containers r that is redelivered to another facility without being injected into your well in quarter p (standard cubic meters).

Q_r,p = Quarterly volume of contents in containers r in quarter p (standard cubic meters).

D = Density of the CO₂ received in containers at standard conditions (metric tons per standard cubic meter): 0.0018682.

p = Quarter of the year.

r = Containers.
