A measurement method approach to control industrial oil mist emissions
(Springer, 2023) Geckin, H.; Tasdemir, Y.; Aygun, A.; Cindoruk, S. S.
Oil mist from polyester yarn and fabric production and metal cutting parts are important sources of air pollutants in urban atmospheres. Especially the 190-210 celcius of flue gases emitted during the thermal fixation of fabrics containing spinning oil. To control the oil emissions, it is necessary to measure both the aerosol and gas phase oil vapor of the high-temperature flue gases discharged from stacks. A new method was developed to determine the oil content in the high-temperature flue gas stream by combining the measurement methods used separately for both aerosol and gas phases at room temperature in the literature with a hybrid approach. With this developed method, oil concentrations were determined in a total of 71 heat-fixing process stacks. The results showed that the oil mist concentration ranged from 0.23 to 297.89 mg/Nm3. It has been determined that the oil concentration was affected by factors such as fabric content, temperature, and whether there was a treatment unit. In the concentration distribution maps prepared in the Surfer program, oil vapor emissions, which were determined to be more intense in the regions close to the source, were revealed to be an important pollutant that should be controlled considering the effects on human health.
