Condensation vessels for liquids and gases

Condensation – an important process in petrochemical manufacturing

Condensation vessels can be found in many diferent stages of distillation and processing of oil products. With gaseous products, for example, 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 specifc 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 one metre.  It’s a diferent story with the measuring ranges in gas traps: almost the entire vessel is flled with liquid and the measuring ranges nearly correspond to the total vessel height, which can be up to approximately 4 m.

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.

Level detection with VEGASWING 63

Because the possible overflling of a condensation vessel represents a high safety risk, reliable detection of the maximum level is absolutely essential.
Due to the fact that it has a wide temperature range and is completely independent of product characteristics, the VEGASWING 63 vibrating level switch is especially suitable for use in this area. Even process temperatures up to 250 °C cannot harm the sensor.

Level measurement in reference vessels with VEGAFLEX 66

The guided microwave measuring principle lends itself well particularly to small measuring ranges up to one metre, which are usual in condensate traps for gases. The single rod VEGAFLEX 66 is the optimal solution for measurement in reference vessels. Together with the bypass tube, the sensor probe forms a coaxial system that can even be used in products with very low dielectric constant (≥ 1.4), such  as liquid gases. Existing displacer systems can be replaced by the sensor without any structural alterations.
