Oil & Gas

Power Generation

Seebach filters help to ensure smooth process operation in petroleum and natural gas production, regardless of whether the oil or gas is extracted from on-shore or off-shore deposits. Filtration, in both the transport and processing of natural gas and crude oil, protects components in downstream plants from contaminants. Filters remove particles and water droplets from gaseous and liquid fuels, and from combustion air, before they enter the combustion chamber. Thus gas turbines are protected from abrasive or baked-on particles.

Natural Gas Fueling Stations

At gas fuel stations, the gas must be free from pollution of oil droplets, liquid water and particles. Gas cleaning is carried out at several locations between storage tanks and dispenser. Removing dispersed water droplets relieves subsequent drying systems. Filter elements that are adapted to the respective working conditions can also operate at high pressure, if necessary, and offer safety for all components within the gas management. This is particularly valid for valves and the installed measuring technology.

Sealing Gas

Modern compressors for gas recovery and compression are equipped with gas seals. These seals work with a sealing gas that isolates the chamber between the compressor oil or the working chamber from the outside atmosphere. The higher the operational pressure the higher the demands are on the dimensional tolerances and surface smoothness of all the components involved. In addition to these criteria, the requirements on the seal gas quality with regard to any particles it might carry also increase. Our filters ensure the functionality and durability of gas seals even at high operational pressures. This also applies to the use of gas seals for isolating the contents of storage tanks from the atm

Amine Scrubbing

Amine scrubbing is a chemical process to remove carbon acid gas, hydrogen sulfide and other sour gases from gas blends. An additional process step to recirculate the amine by heart treatment is necessary. This procedure is used in refineries and natural gas and petrochemical plants. Seebach elements, made from stainless steel and special alloys like Hastelloy, are highly chemical resistant and can help to extend maintenance intervals and reduce operating cost.

Phase separation / coalescer

Our filters with stainless steel or titanium fibre fleeces are ideally suited for the separation of liquids from gas flows, because they cause droplets dispersed in the gas flow to coalesce within the filter medium so that the collected liquid can drain into a storage reservoir.  They can be used for both droplet-shaped impurities in gas and air flows and for the recovery of droplets of a valuable product, which have been carried with the gas flow behind a condenser.  One important example of this is in ammonia production, during which the condensed product is separated from nitrogen and hydrogen that has not reacted. The gases are returned to the reactor. Similar applications can be fo

Petrochemical Industry

The FCC process (fluid catalytic cracking) is used in the petrochemical industry to transform boiling hot crude oil and slurry oil into diesel oil, C3/C4 olefins, and other low boiling point components. The chemical reactions take place in presence of a solid catalyst, e.g. in a fluidized bed. Our filters are used for the efficient separation and recovery of the catalyst.

Catalyst recovery

Many chemical reactions take place in the presence of a solid catalyst. Powdery catalysts based on noble metals (e.g. platinum) or zinc complexes are frequently used. These catalysts are often highly specialized and therefore very expensive.  Cross-flow filtration allows for continuous catalyst recovery from reaction mixtures and subsequent return into the process. This means long-term cost savings. Again filter elements made form stainless steel or special alloys are best suited to the task due to their extensive chemical resistance. Typical examples of the application of our filters for catalyst recovery are the production of polyurethane via the intermediates toluene diamine (TDA) and to

Processing cooling lubricants

In metal cutting, the maintenance and recycling of cooling lubricants is essential for securing a long working life for these highly specialized mixtures of water, oils and auxiliary substances. In addition, continuous separation of particles is an essential precondition for meeting surface qualities and dimensional tolerances during turning, milling, and grinding processes. For example, cooling lubricants are injected under high pressure in cutting machines. Here, particle filtration is essential for protecting the high pressure pump. Our filters also play an important role in the cleaning solution cycle in cabinets for cleaning parts after machining.

Fracking

Fracking is a shorthand for Hydraulic Fracturing and involves pumping water containing several additives and proppants into to a deposit in such a way that the gas containing rocks fracture and release the gas trapped within them. The gas produced by this means is lifted to the surface with the flowback, a mixture of the fracking fluid and underground water. This flowback is contaminated by a variety of substances and has been treated insufficiently so far,  Seebach is participating in a cooperation project for the development of an energy-efficient process for treating this water, which, among other things, is highly saline, and the investigation of the potential for recovering valuable s

Hot Gases

Our stainless and special steels filters are ideally suited for de-dusting hot exhaust gases. A typical application is product cleaning after wood gasification. Depending on the quality of the raw materials used, the product gases contain condensate (tar), ash, and dust. If polymeric filter media are used, the gases must be cooled before filtration. Consequently abrasive or adhering particles enter the heat exchanger, which may cause operational problems.  High temperature resistant filters enable hot gases to be de-dusted and consequently protect all following components.

Offshore

There are a variety of applications for filters and separators In offshore petroleum and natural gas recovery. They include sea water filtration prior to injecting the water into the well in order to increase the delivery pressure.  Other important applications arise in processing the mixture of oil/gas, water, and sand coming up from the well. This mixture is separated in single stages on-site. Additionally filters play a decisive role for the functionality of the essential safety system in oil and gas production: the blowout preventer (BOP). BOPs prevent oil and gas from blowing out of the bore hole at high pressure when it can ignite and cause serious environmental damage. A BOP consists
