Measuring air pollutants emissions in outer air from liquid stored in tank

摘要

The surface runs through the uppermost range of the floating roof tank wall, for determining the speed with an air speed measuring unit, and determining the direction of the vertical air-flow entering through the measuring surface, and an air sample flow is supplied to the inlet of an air pollution measuring system. This is carried out using a suitable mechanical construction using ropes or crane system and are arranged at the measurement place provided for the measurements corresp. to a measuring cycle. The system can consist of multiple units one behind the other, so that for all the measurement places of the entire measurement surface, plots the statistical balances of the local pollution flows, and from these balances, the air pollution flow through the entire measurement surface. In certain cases classified according to its individual pollution components, which are determined. So that an approximation to the desired measurement accuracy can be reached, by a suitable large selected number of measuring cycles.
