Update on Siemens Water Solutions

Fact Sheet:

Status: February, 2014

Siemens has announced that its Industry Sector has sold the Water Technologies business to AEA Investors LP, New York, USA [ Press Release Siemens Industry ]. The sale includes the capital and service business for water treatment in the municipal and general industry markets, and the new company has been named Evoqua Water Technologies. Siemens will continue as before to focus its water-related activities on automation and drive solutions for the operation of water and sewage treatment plants and seawater desalination plants, which is part of the Industrial Automation Systems Business Unit.

Additionally, the sale does not include Siemens Water Solutions, which is a part of the Siemens Energy Sector, Oil & Gas business, providing water and wastewater treatment solutions to the oil and gas market. Besides the solutions business for water within the Power Generation Division, compressors and blowers for water treatment and ventilation will also remain in the Energy Sector.

Oil & Gas Flowback and Offshore Reverse Osmosis (RO) services business: Siemens Energy will retain this core business, as it is an important element of our portfolio of solutions for oil and gas customers. Siemens Water Solutions offers flowback services that are used by our customers for several different operations, including:

• New well completions on the shelf and in deepwater • Subsea flow line displacement operations • Rig and coiled tubing well work-over operations • Acid stimulation and scale squeeze operations • Major oil & gas transmission pipeline hydro-test operations • Pipeline and infield flow line abandonment (sea water flushing) operations

Reverse osmosis services include the supply of potable water for use in various applications by converting seawater or produced water into potable water on-site by using our proprietary reverse osmosis system.

Inquiries related to water treatment in refineries and petrochemical plants: Siemens Energy will continue to innovate, grow and serve our oil and gas customers, whether they are upstream, downstream, onshore or offshore, with full solutions for water and wastewater treatment to achieve water quality suitable for use, re-use or disposal.

The narrow tapered section is Our liquid/liquid hydrocyclone is one of the most advanced, made of duplex stainless steel. yet least complicated oil/water separation devices available. It provides maximum separation efficiency for These materials of construction provide superior the smallest space impact of the available technologies. erosion and corrosion resistance for a long design life. Our hydrocyclone liners have a unique, non-threaded Principle of Operation construction which reduces manufacturing cost and Hydrocyclones operate under system pressure, and use eliminates galling potential, to achieve near 100 percent pressure drop as the primary source of energy. equipment service time. Each hydrocyclone liner in a vessel is fed tangentially to initiate a high radial velocity. The spinning motion of the fluid is accelerated by the tapered shape of the hydrocyclone liner, and the spinning motion creates a centrifugal force up to 4,000 G´s which causes the oil and water to separate rapidly. The oil forms a core at the axis of the hydrocyclone and is forced out via a centered opening at the inlet end of the hydrocyclone liner. The result is a simple but effective, and very compact, oil/water separator with no moving parts.

Twin Ports Our hydrocyclone liners feature twin inlet ports which provide superior hydraulic stability with a straight oil core that is stable even at very low flow rates. The stable oil core enables the hydrocyclone to achieve higher removal efficiencies that can reduce or eliminate the need for emulsion breaking chemicals.

Applications As an added feature, we have designed a SPINSEP™ system ¡¡ Offshore/onshore produced water containing moderate specific to applications that experience extreme movement, concentrations of oil and grease such as floating platforms (Spar, TLP, FPSO). ¡¡ Refinery wastewater treatment ¡¡ Removal of pulp from wastewater in the paper industry ¡¡ Treatment of oily wastewater Flotation Process As the influent enters, it is flowed through the Spiralsep™ unit installed in the inlet piping to the vessel. This component initiates gravity separation of the incoming liquid and if necessary mixes incoming flotation aids such as chemical water. The circular motion created in the SPINSEP™ system by the 90-degree inlet angle results in greater path distance the liquid must travel, resulting in improved removal efficiency. The SPIRALSEP™ unit also stimulates gas bubbles and oil droplet attachment by enhancing oil droplet sizes. Oil droplets attach and grow on the surface of the pack medium until oil droplet size overcomes the bond with the packing material, where they are skimmed into the oil bucket. Water flowing through the gas flotation zone below the packing scrubs it clean of attached oil. These droplets rise to the surface and are skimmed with incoming free oil. Flotation gas bubbles are generated by a number of different methods including DGF, eductor and sparge tubes.
