Vega has the solution for all measuring demands in condensation vessels for liquids and gases.
Condensation vessels are used in many different stages of the distillation and processing of oil products. With gaseous products such as propane, the still liquid fractions condense out and are fed back. With liquid distillates, the condenser separates out the 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 one metre. However, it is 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, anything up to 4 m.
Level measurement in gas traps with Vegaflex 65
With its coaxial measuring system, Vega’s guided microwave sensor the, Vegaflex 65, is particularly well suited for implementation in condensate traps without the use of an additional reference vessel. The sensor’s applied concentric tube prevents it from being affected by strong turbulence on the product surface. It measures the level of any of the different hydrocarbons reliably, from high boiling point derivatives to liquid gases.
Level detection with Vegaswing 63
Because the possible overfilling 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, Vega’s Vegaswing 63 vibrating level switch is especially suitable for use in this area. Even process temperatures up to 250°C do not 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, such as liquid gases. Existing displacer systems can be replaced by this sensor without any structural alterations.
