| Popis: | Lawrence Berkeley National Laboratory developed a simple, efficient, and cost-effective replacement for the traditional glass column system used to monitor H and C emissions from rooftop stacks. The primary goals in developing a replacement (the modified jar system) were to 1) maintain or improve collection efficiency while keeping leakage to less than 5%, 2) simplify the set-up process, and 3) reduce costs. Both the traditional glass column assembly and the modified jar system were operated in tandem for a 13-mo period. Results showed that the modified sample jar system provided equivalent or improved collection efficiency for both H and C. Additional advantages included reduced leak-test errors, quicker and simpler set-up, and material costs that were reduced by nearly an order of magnitude. |
