The rhythmic whir of helicopter blades cuts through the cold North Sea air as Anders Kandborg, a service technician from Busch Denmark, prepares to land on a massive oil platform. Two hundred kilometers off the Danish coast, surrounded only by wind and waves, he begins a demanding service mission. His task: to ensure the reliable operation of a vacuum system from Busch Vacuum Solutions, Germany, that is critical for the oil platform’s production process. As soon as the helicopter touches down, Anders is immersed in a world of steel, pressure, and precision. Equipped with tools and diagnostic instruments, he makes his way to the heart of the operation: the vacuum system room. For the next days, the service technician from Busch inspects, maintains, and optimizes the Dolphin liquid ring vacuum pumps that form the backbone of the platform’s vacuum degassing system. Each pump must run flawlessly to ensure stable production. He also trains workers in handling and maintaining the vacuum pumps. Before his first mission on the oil platform, he participated in BOSIET (Basic Offshore Safety Induction and Emergency Training) – a three-day survival course that includes helicopter evacuation, firefighting, first aid, and sea survival exercises. “It is like being in a completely different world,” he explains. “You learn to handle any situation – even jumping into the sea from a helicopter if you have to.” This course has to be renewed every four years. Pushing the oil from the rock to the surface

The vacuum system from Busch on the platform consists of two Dolphin liquid ring vacuum pumps, each with two ejectors. It plays a crucial role in seawater injection – a process that keeps oil production efficient. Maintaining stable pressure inside an underground oil field is essential because it helps push the oil toward the production wells. As oil is extracted, this pressure drops. If it becomes too low, the flow of oil slows down drastically or may even stop. By maintaining pressure via seawater injection, oil recovery stays efficient as more oil can be extracted from the same reservoir. During this process, high-pressure injection pumps force the seawater down specially drilled injection wells. These wells reach into the same rock formations that hold the oil. The injected water fills the empty spaces left by the extracted oil, pushing remaining oil toward production wells and restoring reservoir pressure – a process known as injection drilling. The role of vacuum degassing in offshore production Before injection, gases like oxygen and carbon dioxide must be removed from the water because they promote corrosion and cause leaks in production facilities. By removing these gases through vacuum degassing, the lifetime of the pipeline is extended, and maintenance costs are reduced. It also lowers the risk of gas-related accidents and equipment failure. In this degassing process, known as seawater deoxygenation, the seawater from the surrounding ocean is pumped into a big tower called deaerator. This tower is kept under vacuum. When water is placed under vacuum, dissolved gases become less soluble and escape from the liquid – much like opening a soda bottle, the change in pressure releases the trapped gas. After the gas is removed from the top of the tower with the help of the vacuum system, the degassed seawater collects at the bottom of the deaerator tower. From there, it is withdrawn through outlet pipes. The oxygen-depleted seawater is then sent either to high-pressure injection pumps for reservoir injection or to cooling systems on the platform. It is used to cool compressors and turbines driving oil and gas processing equipment. After a few days of demanding work under harsh offshore conditions, Anders completes his maintenance tasks and final checks. The vacuum system is running smoothly, ensuring the platform’s production continues without interruption. As he boards the helicopter for the flight back to shore, he takes one last look at the vast expanse of sea and steel beneath him. “It’s a tough job,” he says with a smile, “but also something special. Not everyone gets to work in a place like this.” Back on solid ground, he feels grateful – for the experience, the teamwork, and the knowledge that his efforts help keep such a complex operation running safely and efficiently. www.buschvacuum.com

Keeping Vacuum Pumps Cool During Summer Months

As temperatures rise, the performance and durability of vacuum pumps can be significantly affected. Maintaining a cool environment for these devices is critical, as most are built to function effectively in ambient temperatures of up to 40 °C. Overheating can lead to accelerated oil degradation, increased maintenance costs, and potential equipment failure, interrupting manufacturing and causing expensive repairs. The importance of keeping pumps coolWhen vacuum pumps operate in ambient temperatures that are hotter than they are designed for, the oil degrades faster compared to a pump running in a cool environment. This means the vacuum pump oil will need to be changed more often, increasing maintenance costs. If plant room temperatures exceed 40°C, vacuum pumps can overheat, potentially leading to a breakdown. Not only can this disrupt manufacturing processes and lead to lost revenue, but it can also result in costly repairs.Plant room ventilation – natural vs forcedNatural ventilation from vents and louvres relies on air movement due to wind or convection to be effective, so its performance can vary depending on the temperature and wind speed. During periods of warm weather, it is usually not possible to achieve the high ventilation flow rates necessary with natural ventilation alone, unless significant portions of plant room walls are open or vented.Effective ventilation for plant roomsProper ventilation is essential to avoid overheating in plant rooms. While louvres and vents may offer some relief, they are often insufficient for the task. For confined spaces, implementing forced ventilation systems, such as cooling fans, is crucial to maintain appropriate temperatures. As ambient temperatures rise, the requirement for ventilation also increases, and air in the plant room needs to be changed more often to prevent it from becoming warm.For example, in an 8m x 4m plant room with equipment heat output of 25kW, the number of air changes per hour needed to prevent exceeding 40°C varies dramatically with the external temperature: - 26 changes at 10 °C outside - 79 changes at 30 °C outsideEstimating the required ventilation flow rateTypically, 80-90% of the absorbed power of a vacuum pump motor becomes heat exhausted into the room. The following calculation can be used to estimate the required ventilation for an enclosed plant room to keep the temperature below 40°C on a hot summer day. The sum of all the operational vacuum pump motor power ratings can be used to estimate heat emission into the room: - Heat emission (in kW) x 200 = ventilation flow requirement (in m3/h) Note: Ensure you also consider the ventilation requirements of other equipment located in the plant room.Heat management solutions - Forced ventilationInstalling a system of fans to exhaust warm air out and draw cool air in is a very effective way of keeping your plant room cool. A control system which can effectively regulate plant room temperature by turning on the required number of fans can enhance energy efficiency. - Exhaust pipingRedirecting the exhaust of vacuum pumps outside the plant room can reduce heat being rejected into the room by up to 35%. Ensure correct material selection for pipework as it can become hot. Also consider insulating the pipe with lagging to protect from hot pipe surfaces and prevent heat from the pipe surface escaping into the plant room. - Heat recoveryUtilizing heat recovery kits, such as those available for certain Busch vacuum pumps, can reclaim up to 80% of the energy used by the vacuum pumps to heat water, providing dual benefits of energy conservation and reduced ventilation needs. - Plant room layoutA well-designed layout can prevent overheating by ensuring adequate space between equipment for proper air circulation. Attention to exhaust and fan directions can also prevent heat transfer to adjacent machinery, which is particularly essential to protect sensitive components such as control systems.SummaryKeeping vacuum pumps cool during hot weather is key to ensuring their reliability and longevity. Adequate ventilation, heat management solutions, and intelligent plant room design are important strategies.

Whitepaper: Leak Detection for Electric Vehicle Battery Production

  Electric vehicles are a decisive factor in reducing CO2 emissions in road traffic. They store the energy required for propulsion in batteries and an electric motor converts it into motion. If the batteries are charged with electricity from renewable energy sources, they even have a completely CO2-free energy balance. Today, lithium-ion batteries are used almost exclusively as accumulators. Vacuum technology is indispensable for their production. This white paper shows how test gas leak detection ensures quality The proper functioning, quality and safety of lithium-ion batteries, which are used as accumulators in electric vehicles, depends on their integrity and impermeability to external influences such as moisture ingress. For this reason, leak detection systems are used in battery production to check the batteries. Pfeiffer Vacuum supplies the necessary vacuum solutions from a single source.

Oil diffusion vacuum pump

The oil diffusion pump is operated with an oil of low vapor pressure. A high speed jet of the Oil is generated by boiling the Oil and directing the vapor through a jet assembly. Note that the oil is gaseous when entering the nozzles. Within the nozzles, the flow changes from laminar, to supersonic and molecular. Often several jets are used in series to enhance the pumping action. The outside of the diffusion pump is cooled using either air flow or a water line. As the vapor jet hits the outer cooled shell of the diffusion pump, the working fluid condenses and is recovered and directed back to the boiler. The pumped gases continue flowing to the base of the pump at increased pressure, flowing out through the diffusion pump outlet, where they are compressed to ambient pressure by the secondary mechanical forepump and exhausted. Diffusion pumps cannot discharge directly into the atmosphere, so a mechanical forepump is typically used to maintain an outlet pressure around 0.1 mbar. Diffusion pumps have no moving parts and as a result are quite durable and reliable. They can function over pressure ranges of 10−10 to 10−2 mbar. They are driven only by convection and thus have a very low energy efficiency and low cost per unit pumping speed when compared with other types of pump used in the same vacuum range. One major disadvantage of diffusion pumps is the tendency to backstream oil into the chamber being evacuated. This oil can contaminate surfaces inside the chamber or upon contact with hot filaments or electrical discharges may result in carbonaceous or siliceous deposits. Generally cold traps and baffles are utilized between the chamber and the diffusion pump to minimize backstreaming, although this results in some loss of pumping ability. The oil of a diffusion pump cannot be exposed to the atmosphere when hot. If this occurs, the oil will burn and has to be replaced .
