Rotork Schischek simplifies petrochemical analysis

Rotork Schischek’s compact explosion-proof valve actuators have been selected as the reliable solution for a critical petrochemical analysis process, the company has reported.

Ecopetrol is the largest petroleum company in Colombia, and it uses Near Infrared Spectroscopy (NIR) to perform quantitative sampling separation of hydrocarbons into four groups: alkanes, aromatics, resins and asphaltenes.

As part of to the process, sets of small two and three-way fast acting ball valves are used to gather the samples for analysis and maintain the pressure, flow and temperature through the spectrometer.

Swift valve operation is vital to maintain the characteristics of the media for accurate sampling. Additional application constraints involve restricted spaces around valves, the hazardous area classification and requirements for failsafe operation, end of travel indication and low power consumption.

Ecopetrol concluded that the electric Schischek actuator could satisfy all these demands and as such approximately 100 Schischek RedMax actuators with associated hardware have been installed.

The actuators are certified for Zones 2 and 22 hazardous area operation, environmentally protected to IP66 and equipped with self-adaptable 24 – 240V AC/DC power supplies. RedMax actuators are one of a range of electrical products designed by Schischek for explosion-proof and non-explosion-proof applications.
