Condensation – an important process in petrochemical manufacturing
Condensation vessels can be found in many different stages of distillation and processing of oil products. With gaseous products, e.g. propane, the still liquid fractions condense out and are fed back. With liquid distillates, the condenser separates out the still highly volatile, gaseous components. The layout of the condensation vessels places specific demands on the applied measurement technology. In condensate traps for gases, the liquid collects in a small vessel extension at the lower end of the condenser. The measuring ranges there are less than 1 m (3 ft). It’s a different story with the measuring ranges in gas traps: almost the entire vessel is filled with liquid and the measuring ranges nearly correspond to the total vessel height, which can be up to approx. 4 m (13 ft).
Level measurement in gas traps with VEGAFLEX 65
With its coaxial measuring system, VEGAFLEX 65 is particularly well suited for implementation in condensate traps without the use of an additional reference vessel. Due to the applied concentric tube, VEGAFLEX 65 is not affected by strong turbulence on the product surface. The sensor reliably measures the level of any of the different hydrocarbons: from high boiling point derivatives to liquid gases.
