Chemical Manufacturer Improves Process Availability

This case study details the application of a low pressure range pressure transmitter in a major chemical manufacturing facility in North America. The primary application involves the vent collection, dilution, and thermal oxidation of volatile organic waste compounds (VOCs) produced during chemical manufacturing. The document outlines the challenges faced by the manufacturer, including strict emissions control standards from the Environmental Protection Agency that necessitate routine calibrations for each transmitter. It describes the process of waste collection and dilution, emphasizing the importance of proper dilution to prevent explosive mixtures. The case study presents the solution implemented, which was the installation of the Rosemount 3051S transmitter. This solution significantly reduced calibration and commissioning time from 45 minutes to 15 minutes and decreased installation costs by approximately $2,000 per unit. The results indicate improved process availability and reduced maintenance time, demonstrating the effectiveness of the new technology in meeting the operational needs of the facility.
