METHOD TO DETERMINE THE QUANTITY OF HALOCARBONS OF EACH TYPE

1. Determination of the quantity of halocarbons in each container

The quantity of halocarbons destroyed must be determined at the destruction facility, by weighing each container when it is full of halocarbons prior to destruction and after it has been emptied and its contents have been destroyed.

The quantity of halocarbons is equal to the difference between the mass of the container when full and when empty.

Each halocarbon container must be weighed at the destruction facility:

(1)  using a single scale to generate both full and empty weight tickets;

(2)  using a scale that has been calibrated by the manufacturer or by a third person certified for that purpose less than 3 months before the weighing, to an accuracy of ± 5%;

(3)  weighing the full container not more than 2 days prior to commencing the destruction of the halocarbons;

(4)  weighing the empty container not more than 2 days after the destruction of the halocarbons.

2. Circulation of mixed halocarbons

For each sample that does not contain over 90% of the same type of halocarbon, the promoter must, in addition to the conditions provided for in Division 1 of this Appendix, also meet the following conditions set out in this Division concerning mixed halocarbon.

The circulation of the halocarbon mixture must be conducted at the destruction facility or prior to delivery of the halocarbon to such a facility, by a person who is independent of the promoter and of the destruction facility and who is properly trained to carry out this task.

Prior to sampling, the halocarbon mixture must be circulated in a container that meets all of the following conditions:

(1)  the container has no solid interior obstructions other than mesh baffles or other interior structures that do not impede circulation;

(2)  the container was fully evacuated prior to filling;

(3)  the container has ports to sample liquid and gas phase halocarbons;

(4)  the sampling ports are located in the middle third of the container and not at one end or the other;

(5)  the container and associated equipment can circulate the mixture through a closed loop system from the bottom to top.

If the original mixed halocarbon container does not meet these requirements, the mixed halocarbon must be transferred into a compliant temporary container.

The mass of the halocarbon mixture transferred into the temporary container must be calculated and recorded. In addition, transfers of halocarbons between containers must be carried out at a pressure that meets the applicable standards for the place where the project is located.

Once the mixed halocarbons are in a container that meets the above criteria, they must be circulated as follows:

(1)  liquid mixtures must be circulated from the liquid port to the vapour port;

(2)  a volume of the mixture equal to 2 times the volume in the container must be circulated;

(3)  circulation must occur at a rate of at least 114 litres per minute unless the liquid mixture has been circulating continuously for at least 8 hours;

(4)  the start and end times must be recorded.

3. Sampling

Sampling must be conducted for each halocarbon container:

(1) in the case of pure halocarbons, 1 sample must be taken at the destruction facility;

(2) in the case of halocarbon mixtures that have been circulated at the destruction facility, a minimum of 2 samples must be taken during the last 30 minutes of circulation and the samples must be taken from the bottom liquid port;

(3) in the case of halocarbon mixtures that have been circulated prior to delivery to the destruction facility, a minimum of 2 samples must be taken in accordance with subparagraph 2, and 1 additional sample must be taken at the destruction facility.

If more than one sample is taken for a single container, the promoter must use the results from the sample with the weighted halocarbon concentration with the least global warming potential.

The sampling must be conducted in accordance with the following conditions:

(1)  the samples must be taken by a person who is independent of the promoter and of the destruction facility and has the necessary training to carry out this task;

(2)  the samples must be taken with a clean, fully evacuated sample bottle with a minimum capacity of 0.454 kg;

(3)  each sample must be taken in a liquid state;

(4)  a minimum sample size of 0.454 kg must be drawn for each sample;

(5)  each sample must be individually labeled and tracked according to the container from which it was taken;

(6)  the following information must be recorded for each sample:

(a)  the time and date of the sample;

(b)  the name of the promoter for whom the sampling is conducted;

(c)  the name and contact information of the person who took the sample, and of the technician’s employer;

(d)  the volume of the container from which the sample was taken;

(e)  the ambient air temperature at the time of sampling;

(f)  the chain of traceability of each sample, from the point of sampling to the accredited laboratory.

4. Analysis of samples

The quantity and type of halocarbon must be determined by having a sample from each container analyzed by one of the following laboratories:

(1) the Centre d’expertise en analyse environnementale du Québec;

(2) a laboratory that is independent of the promoter and of the destruction facility and accredited for analysis of halocarbons by the Air-Conditioning, Heating and Refrigeration Institute in accordance with the most recent version of AHRI 700 of that organization.

All the halocarbon samples for the project must be sampled to determine the following:

(1)  the type of each halocarbon;

(2)  the quantity, in metric tonnes, and concentration, in metric tonnes of halocarbon of type i per metric tonne of gas, of each type of halocarbon in the gas, using gas chromatography;

(3)  the moisture content of each sample;

(4)  the high boiling residue from the halocarbon sample, which must be below 10% of the total mass of the sample.

In the case of halocarbon mixtures, the analysis must determine the weighted concentrations of the halocarbon on the basis of their global warming potential for samples taken in accordance with subparagraph 2 of the first paragraph of Division 3 of this Appendix.

A certificate of the sampling results must be issued by the laboratory that conducted the analysis and a copy of the certificate must be included with the project report.

For each container for which the moisture content of the sample determined under subparagraph 3 of the second paragraph of this Division is above 75% of the saturation point for the halocarbon, the promoter must

(1)  dry the halocarbon mixture and, in the case of mixed halocarbons, conduct the circulation again in accordance with the method provided for in Division 2 of this Appendix, and sample and analyze it in accordance with the method in Divisions 3 and 4 of this Appendix; or

(2)  deduct the water weight that must be determined, for each container, using the following method:

(a)  from the result of the moisture content analysis as regards the quantity of dissolved water;

(b)  by using a transparent graduated cylinder to determine the quantity of free water.

5. Determination of the final quantity of halocarbons of type i contained in foam extracted and sent for destruction (QF final, i) and the quantity of halocarbon of type i used or intended to be used as refrigerants that are recovered and sent for destruction (QR i)

Based on the mass of the halocarbons in each container and the concentration of each sample, the promoter must

(1) for each container for which the moisture content of the sample is above 75% of the saturation point for the halocarbons, deduct the water weight;

(2) calculate the quantity of each type of halocarbon in each container, by deducting the weight of the high boiling residue; and

(3) add together the quantities of each type of halocarbon in each container to obtain the factor QF final, i, namely the final quantity of halocarbon of type i contained in the foam, or the factor QR i, namely the quantity of halocarbon of type i used or intended to be used as refrigerants recovered and sent for destruction under the project.
