§98.423. Calculating CO 2 supply. — Inbound Citations

(ii) Reporters that have a mass flow meter or volumetric flow meter installed to measure the flow of a CO2 stream that meets the requirements of paragraph (a)(1)(i) of this section shall base calculations in § 98.423 of this subpart on the installed mass flow or volumetric flow meters.

(1) Reporters following the procedures in § 98.423(a) shall determine quantity using a flow meter or meters located in accordance with this paragraph.

(i) If the CO2 stream is segregated such that only a portion is captured for commercial application or for injection, you must locate the flow meter according to the following:

(A) For reporters following the procedures in § 98.423(a)(3)(i), you must locate the flow meter(s) after the point of segregation.

(B) For reporters following the procedures in paragraph (a)(3)(ii) of § 98.423, you must locate the main flow meter(s) on the captured CO2 stream(s) prior to the point of segregation and the subsequent flow meter(s) on the CO2 stream(s) for on-site use after the point of segregation. You may only follow the procedures in paragraph (a)(3)(ii) of § 98.423 if the CO2 stream(s) for on-site use is/are the only diversion(s) from the main, captured CO2 stream(s) after the main flow meter location(s).

(ii) Reporters that have a mass flow meter or volumetric flow meter installed to measure the flow of a CO2 stream that meets the requirements of paragraph (a)(1)(i) of this section shall base calculations in § 98.423 of this subpart on the installed mass flow or volumetric flow meters.

(iii) Reporters that do not have a mass flow meter or volumetric flow meter installed to measure the flow of the CO2 stream that meets the requirements of paragraph (a)(1)(i) of this section shall base calculations in § 98.423 of this subpart on the flow of gas transferred off site using a mass flow meter or a volumetric flow meter located at the point of off-site transfer.

(b) As an alternative to paragraphs (a)(1) through (3) of this section for CO2 that is supplied in containers, calculate the annual mass of CO2 supplied in containers delivered by each CO2 stream in accordance with the procedures specified in either paragraph (b)(1) or (b)(2) of this section. If multiple CO2 streams are used to deliver CO2 to containers, you shall calculate the annual mass of CO2 supplied in containers delivered by all CO2 streams according to the procedures specified in paragraph (b)(3) of this section.

(1) For each CO2 stream that delivers CO2 to containers, for which mass is measured, you shall calculate CO2 supply in containers using Equation PP-1 of this section.

(2) For each CO2 stream that delivers to containers, for which volume is measured, you shall calculate CO2 supply in containers using Equation PP-2 of this section.

(3) To aggregate data, sum the mass of CO2 supplied in containers delivered by all CO2 streams in accordance with Equation PP-3a of this section.

(b) As an alternative to paragraphs (a)(1) through (3) of this section for CO2 that is supplied in containers, calculate the annual mass of CO2 supplied in containers delivered by each CO2 stream in accordance with the procedures specified in either paragraph (b)(1) or (b)(2) of this section. If multiple CO2 streams are used to deliver CO2 to containers, you shall calculate the annual mass of CO2 supplied in containers delivered by all CO2 streams according to the procedures specified in paragraph (b)(3) of this section.

(1) For each CO2 stream that delivers CO2 to containers, for which mass is measured, you shall calculate CO2 supply in containers using Equation PP-1 of this section.

(2) For each CO2 stream that delivers to containers, for which volume is measured, you shall calculate CO2 supply in containers using Equation PP-2 of this section.

(3) To aggregate data, sum the mass of CO2 supplied in containers delivered by all CO2 streams in accordance with Equation PP-3a of this section.

(A) For reporters following the procedures in § 98.423(a)(3)(i), you must locate the flow meter(s) after the point of segregation.

(B) For reporters following the procedures in paragraph (a)(3)(ii) of § 98.423, you must locate the main flow meter(s) on the captured CO2 stream(s) prior to the point of segregation and the subsequent flow meter(s) on the CO2 stream(s) for on-site use after the point of segregation. You may only follow the procedures in paragraph (a)(3)(ii) of § 98.423 if the CO2 stream(s) for on-site use is/are the only diversion(s) from the main, captured CO2 stream(s) after the main flow meter location(s).

(2) Reporters following the procedures in paragraph (b) of § 98.423 shall determine quantity in accordance with this paragraph.

(i) Reporters that supply CO2 in containers using weigh bills, scales, or load cells shall measure the mass of contents of each CO2 container to which the CO2 stream is delivered, sum the mass of contents supplied in all containers to which the CO2 stream is delivered during each quarter, sample the CO2 stream delivering CO2 to containers on a quarterly basis to determine the composition of the CO2 stream, and apply Equation PP-1.

(ii) Reporters that supply CO2 in containers using loaded container volumes shall measure the volume of contents of each CO2 container to which the CO2 stream is delivered, sum the volume of contents supplied in all containers to which the CO2 stream is delivered during each quarter, sample the CO2 stream on a quarterly basis to determine the composition of the CO2 stream, determine the density quarterly, and apply Equation PP-2.
