METHOD AND INSTALLATION TO TAKE SAMPLES AND DETERMINATION OF PRESENCE OF CHEMICAL COMPOUNDS IN VESSELS

摘要

FIELD: pollution control. SUBSTANCE: method includes several stages: pumping of compressed air under pressure into specified vessels to drive at least part of its contents, extraction of sample of contents of vessel with the aid of exhaust pump and analysis of sample extracted by means of exhaust pump to determine presence or absence of some residues in it. Compressed air is pumped through nozzle into hole in vessel to drive out part of contents of vessel and to form cloud of sample outside of vessel. Then cloud of sample is at least partially extracted with the aid of exhaust pump by suction and sample is analyzed for presence of pollutants, for instance, nitrogen-carrying combinations and hydrocarbons. According to one version of implementation of method about 90% of extracted sample is taken away from analyzer and is recirculated into injector. another version of implementation of method provides for fan blow away remainder of cloud of sample downstream of technological network from installation for monitoring. Cap may be envisaged in enclosure of installation to ensure proper dynamic in area for removal of these remainders. EFFECT: enhanced functional reliability of method.
