The article deals with the issue of the influence of ambient temperature on the initial height of the flare emissions rise. The paper presents full-scale and theoretical studies of flare emissions operating near a temporary residential complex. In the course of the work, a series of images of flare emissions at different ambient temperature conditions was carried out and their subsequent comparison with the theoretical model was carried out. Field studies verify the theoretical model and establish that the initial height of the flare emissions depends on the ambient temperature and has an inverse proportionality.

The article discusses the impact of emissions into the atmosphere, formed as a result of combustion of associated petroleum gas, on the chemical composition of settled dust near the gas torch. The paper presents full-scale studies of the emissions of a torch operating near a settlement, the chemical composition of particles in the obtained samples of settled dust is studied. In the course of the work, the results obtained were compared with research data obtained for areas where there is no flare combustion. As a result of this comparison, it was concluded that flare emissions have a significant impact on the chemical composition of settled dust in the vicinity of existing flare systems.
