A larger fraction of crude oil after the atmospheric distillation is driven into the vacuum distillation unit which is one of the most productive and critical equipment in the refinery. The vacuum in the distillation column is kept by a multi stage steam ejector unit which includes:
- booster ejector ( first ejector connected to the distillation tower)
- main condensers and deaeration unit, also with steam ejector in some cases
- liquid ring vacuum pump.
Jet vacuum pumps are often used in combination with liquid ring pumps to create vacuum in crude oil distillation columns.
The combination of the two pump types together with simple but appropriate control systems facilitate a low consumption of cooling water, power and motive medium.
Condensers are arranged between the jet vacuum pumps. As far as possible, the drawn-off vapors and the motive medium are condensed thus reducing the flow which the liquid ring pump has to handle.
GEA jet vacuum pumps are perfectly suited to this application. They convey large quantities of gas, operate smoothly and need very little maintenance. A wide choice of materials means that corrosion can be reduced or eliminated.

Absorption & Gas Scrubbing
GEA supplies scrubbers for an efficient multi-pollutant cleaning of process-and-exhaust gases for various applications.

Centrifugal Separator
GEA separators are designed for liquid-based applications. Using centrifugal force, they are used for separating suspensions consisting of two or more phases of different densities, i.e. they can be used for liquid-liquid separation, for liquid-liquid-solid separation or for liquid-solid separation. They are equally as effective at separating liq...

Cooling, quenching & conditioning
The Rapid Cooling or Quenching of gas streams is used in several essential applications in the process industries.

Decanter Centrifuge
The decanter’s hour has come as soon as the solids content in the suspension to be processed is particularly high. These machines provide the benefits of high clarifying efficiency and maximum dewatering as well as the separation of liquids with the simultaneous removal of solids. The main requirements in this respect include a high bowl speed, a...

The breakthrough that changed spray drying
In 1976, NIRO engineers responded to a competitive challenge by rethinking what spray drying could do. Their idea became the multi-stage dryer MSD. Fifty years later, the same fundamental principle helps turn liquids into the powders used in essential nutrition products and important medicines around the world. Refined through decades of engineering expertise, customer insight and continuous development, MSD is a story of innovation with lasting impact.

Beyond the machine: unlocking better plant performance
An efficient machine does not automatically make an efficient factory. Real improvement often starts by looking beyond individual equipment and understanding how processes, energy systems and operating decisions affect one another. It’s a holistic approach designed to uncover opportunities that might otherwise be missed.

How a valve reshapes the way food and drinks are made
In food and beverage plants, valves are commonly operated using compressed air. GEA Hydract® Actuation Technology moves valves with water instead, in a closed, digitally controlled circuit. The result is a valve that can be held exactly in place and steered in fine-tuned steps. This results in lower energy use and greater control.
