ASTM D5837 Formaldehyde in Air Emissions Test
The ASTM D5837 standard is a critical tool used to measure formaldehyde emissions from various industrial processes, particularly those within the oil and gas sector. This test assesses the concentration of formaldehyde in air emissions which can result from incomplete combustion or other industrial activities.
Formaldehyde (HCHO) is classified as a hazardous substance due to its potential health impacts when inhaled. Industries involved with oil and gas, chemical manufacturing, and waste incineration are required by law to monitor and control formaldehyde emissions into the environment. By adhering to the ASTM D5837 standard, these industries ensure compliance with regulatory requirements such as those set forth by OSHA (Occupational Safety and Health Administration) in the United States.
The test method involves sampling air from the emission source using a suitable sampling device, typically an impinger or denuders. The collected samples are then analyzed for formaldehyde content through various analytical techniques including gas chromatography with flame ionization detection (GC-FID). This approach allows for precise quantification of formaldehyde levels down to parts per billion (ppb).
Preparation of the sample is crucial prior to analysis. After collection, samples must be stored under controlled conditions to prevent degradation or volatilization of formaldehyde. Proper handling procedures include refrigeration and minimizing exposure to light.
The ASTM D5837 test provides detailed guidelines for sampling frequency and duration based on the nature of the emission source. For continuous sources, samples might be taken every hour over a 24-hour period; whereas intermittent sources may require fewer but more concentrated measurements.
Interpretation of results from ASTM D5837 helps operators identify areas for improvement in their processes to reduce formaldehyde emissions. Regular monitoring ensures compliance with local and international regulations, thereby protecting both worker health and environmental quality.
