Petrochemical sampling and analysis
Published: 15 March, 2016
Rotork Schischek says its compact explosionproof valve actuators have been selected as the reliable solution for a critical petrochemical analysis process.
Ecopetrol is a large petroleum company in Colombia, engaged in oil and gas exploration, production and refining. The company uses Near Infrared Spectroscopy (NIR) to perform quantitative sampling separation of hydrocarbons. The process separates the hydrocarbons into four chemical groups – alkanes, aromatics, resins and asphaltenes.
Central to the operation of the process, sets of small two and three-way fast acting ball valves are used to gather the samples for analysis and precisely maintain the pressure, flow and temperature through the spectrometer.
Swift valve operation (typically less than three seconds) is essential to maintain the characteristics of the media for accurate sampling.
