Before measurement, the homogeneity of the stack gas shall be tested. Perform homogeneity testing in accordance with ISO 10396. Use the CO2 concentration as measurand. If homogeneity testing is successful, sampling can be done on a single point.Comprehensive measurement planning shall be performed before sampling, taking into consideration the specific measurement task.
If stack gas pre-sample and analysis equipment is already present, part of this gas sampling stream can be used to collect the sample. If that is not the case, a probe suitable for gas sampling, equipped with an in-stack or out of stack filter for removal of particulate matter shall be used, and provisions shall be made for excess water removal. To ensure representative sampling and to ensure the equivalence between the measured total CO2 concentration and the CO2 sampled for the 14C analysis, accepted standards for the measurement of bulk components in stack gas, namely ISO 10396 or EN 15259,[4] shall be used.
There are several methods for intermediate storage of the collected CO2. The simplest solution is the use of a gasbag. If long storage periods are expected, the use of aluminium-lined gas bags is preferred to prevent the ingress of CO2 from ambient air. Proper blank procedures shall ensure that suitable gas bags were used.
When more CO2 has to be collected, a gas cylinder can be used for storage. Standard canisters can be used for this purpose. Provisions shall be made for controlled intake of stack gas independent of pressure build-up during the sampling process.
If standard gas analysis probes and pre-sample systems are present, part of the conditioned gas can be used for CO2 sampling. The standard gas analysis can be combined with simultaneous sampling of CO2 as long as this sampling does not affect the standard gas analysis (consider the required sample flow and the risk of leakage).
If the required measurements concern a steady-state situation, a sampling setup as shown in Figure 1 or equivalent may be used. ISO 13833 pdf free download.
