Gas Flow Meter in India

1. Downloaded from: justpaste.it/hcog7 Gas Flow Meter in India In a commercial-grade hydrochloric acid (HCl) production process, a synthesis unit utilizes a 2000°C top-fired combustion chamber made from impervious graphite (steel-jacketed) to process hydrogen and chlorine. The unabsorbed HCl gases are subsequently directed to a Tail Gas Tower (TGT), where the majority of HCl traces are absorbed. The remaining vent gas, which contains trace amounts of HCl (<5 ppbv) and water vapor, is then vented out of the system. Challenge: The customer encountered difficulty in installing a flowmeter for measuring the vent gas, which contains: Trace amounts of HCl (<5 ppbv). Water vapor. Very low gas velocity. The customer reported that no existing flow measurement solution was capable of handling these specific conditions effectively, particularly due to the corrosive nature of HCl and the low velocity of the vent gas. Proposed Solution: After thorough analysis of the customer's requirements and challenges, the expert proposes a customized flow measurement solution that incorporates a HALAR-coated sensor probe. HALAR coating (perfluoroalkoxy) offers several advantages: 1. Chemical Resistance: HALAR is known for its excellent resistance to a wide range of chemicals, including hydrochloric acid. This makes it an ideal choice for the sensor probe exposed to the corrosive vent gases. 2. Water Vapor Compatibility: The coating also performs well in environments containing water vapor, preventing issues such as condensation or corrosion in the measurement system. 3. Durability: The HALAR coating enhances the longevity and durability of the sensor probe, especially in the harsh conditions of the vent gas stream.

2. The wetted parts of the flowmeter, which come into direct contact with the vent gas, will be coated with HALAR to ensure they can withstand the corrosive effects of HCl and water vapor. This customized solution will allow for accurate flow measurement, even at very low gas velocities, while also ensuring the longevity of the equipment.https://leomi.in/vent-process- gas-flow-measurement-in-chemical-industry/ The HALAR-coated sensor probe provides a practical and durable solution to the flow measurement challenge in the vent gas stream, offering accurate results while withstanding the harsh chemical and environmental conditions. This customized approach ensures reliable operation, even in a challenging industrial setting where traditional flowmeters would not perform adequately.
