Compressed air filters raise efficiency, lower pressure drop

Atlas Copco Compressors has a new range of DD+, PD+, DDp+ and PDp+ standard and high pressure filters, which can provide a pressure drop of half that associated with conventional coalescing or particulate filters.

THe lower pressure drop, and hence energy savings, are linked to the engineered housing and cartridge, as well as the head design. Other features include stainless steel filter cores that, said Atlas Copco, ensure durability of the cartridges and drastically reduce the risk of implosion.

Meanwhile, new micro-glass fiber filter media and a six layer wrapped construction provide for a high purity filtration and a guaranteed performance over the filter lifetime.

Compared to the previous generation, the pressure drop of the new DD+ and PD+ filters has also been reduced and at the same time oil carry has decreased by more than 20%.

The new dust filters also have particle removal efficiencies of 99,92 % (DDp+) and 99,98 % (PDp+), the supplier added.

Sulzer has taken a strategic decision to focus the company’s activities in three key markets—oil and gas, power, and water. These markets, which accounted for about two thirds of the company’s sales in 2012. After a potential divestiture of Sulzer Metco, these three markets would account for almost 80% of sales—with oil and gas at 48%, power at 16%, and water at 15%.

UK innovation agency the Technology Strategy Board has awarded Amarinth a £250k grant to further develop a design/production process for an energy-efficient molten sulphur pump for the petchem industry. Amarinth has been developing a process to make bespoke best efficiency point (BEP) optimised impellers that can be produced affordably on short lead times. Centrifugal pumps used in industry are often a ‘best fit’ selection from a standard range of pumps and most pumps don't run at their BEP, with energy inefficiencies of up to 25% often found, said Amarinth.

Chemineer
has introduced a new gearbox for agitator duties, which is designed to provide lower maintenance costs and higher productivity. The bearing and gear life of the Model 20 HT/GT gearbox are enhanced by an oversized output shaft that reduces gear deflection and noise, while a true dry well seal prevents lubricant leaking down the shaft. The gearbox also has a recessed low-speed coupling half that simplifies installation by removing the need to install the extension shaft up through the gearbox.

Zettlex Ltd has expanded its production operations in Newton, Cambridgeshire and is recruiting additional production and engineering staff. Mark Howard, Zettlex general manager linked the move to increased sales of the company's IncOder high precision angle encoders, particularly from South Korea, Turkey, Germany, North America and Belgium. The measurement performance of the IncOder is unaffected by humidity, moisture, condensation or dust and so is suitable for use in harsh environments where electrical contacts, optical encoders or capacitive devices may be unreliable.

Schaeffler has launched an online, interactive information guide to help companies correctly mount and dismount rolling bearings. The Schaeffler Mounting Toolbox is a web-based information guide on how to professionally install rolling bearings and the tools required to do this. As well as learning about which tools and fitting aids are required, users can also view short educational videos that demonstrate how these tools should be used in practice.

IMTEX's latest range of valve communication systems can communicate actual valve position on a continuous basis. This enables process engineers to check for valve stiction, which if left undetected, could lead to increased operating costs and/or compromised process quality. Target markets include oil, gas & petrochemicals, chemicals, food & beverage, energy/power, marine/offshore, metal processing and pharma.

Stainless steel and plastic vertical float switches from Cynergy3 Components are now available with industry standard M12 round 4-pin connectors and cables. The offer quick-connection, plug-in switches for controlling the filling and emptying of process/liquid storage tanks. The first switches with the new M12 connectors is the RSF66P series of PPS (polyphenylene sulphide) vertical float switches.

Cooper Crouse-Hinds has gained new ATEX and IECEx approvals for its Ex-e (increased safety) GHG 410 range of safety and isolating transformers. These transformers are suitable for use in potentially explosive atmospheres. Safety and isolating transformers are used for the power supply of control circuits. The use of these transformers is stipulated in the EN 61558-2-1 standard. This requires the use of safety and isolation transformers if more than five operating coils are used in one circuit.

Viscose fibres could advance filtration

At the Filtech conference in Wiesbaden, Germany, from October 22-24, Dr Philipp Wimmer of Kelheim Fibres explained how the properties of a filter could be precisely controlled and optimised by the addition of speciality viscose fibres in nonwovens.
 
In contrast to other cellulosic fibres such as cotton, for example, viscose fibres stand out as a result of their definable and reproducible geometry, which enables a perfect match to be made to the specific processing route or end application.

The porosity or surface of a filter can also be controlled precisely by adding the appropriate viscose fibres with specific cross sections. 
 
The incorporation of functional additives further allows the manufacture of tailor-made fibres according to the end product’s exact demands.
 
The benefit is that the additives are locked in the fibre and have no impact on the filter’s physical properties – and at the same time, they maintain their effect.
 
Kelheim’s fibres are ISEGA certified and medically and environmentally compatible. They are therefore ideally suited for sensible applications like hygiene or medical products, for example in HME filters (Heat and Moisture Exchange filters) used in respiration equipment.

Viscose fibres are carbon neutral when incinerated at the end of the filter’s life span or can – depending on the residue in the filter – be composted.
 
One interesting potential application cited for these filters is in the decolouring of waste water of dye factories: tests have shown that filters with the cationic activated Danufil Deep Dye fibre offer particularly fast and effective dye absorption.

Foundation Fieldbus, HART in merger talks


The Fieldbus Foundation (FF) and the HART Communication Foundation are talks about a merger that would form a single industry body for device communications in the process automation sector. Mid-2014 has been set as a target date for completion.

The organisations are to each set up a team to study the merger. This would including looking at scope for collaboration and the economies of scale to be realised in training, testing and registration, as well as in marketing and communications. 

Under the proposals being discussed, both the FOUNDATION Fieldbus and HART specifications would continue to exist and evolve separately. The merged organisation would also continue to support the existing wireless strategies within each organisation. 

The merger would provide significant benefits to both end users and suppliers, Dr. Gunther Kegel, chairman of the FF and his HART counterpart Mark Schumacher said in a joint statement

The link-up, they believe, offers significant potential to harmonise many aspects of the two protocols, making it easier for end users and suppliers to implement the technology and obtain the full benefits of each technology in plant operations. 

"For end users, a single organisation that combines the power of both Fieldbus Foundation and HART Communication Foundation would provide a full solution that addresses every conceivable aspect of field communications and intelligent device management for the process industries," said the statement.

"For suppliers, a single organisation would create efficiencies in resource utilisation, consistency of processes and procedures, and would deliver significant improvements in member services and support,”  it added.

The two organisations have worked together in the past, for example on common international standards such as Electronic Device Description Language (EDDL) and, most recently, the development of the Field Device Integration (FDI) specification.
