Filtration and Separation
Bagfilters are the technology of choice when low dust content is needed for gas cleaning. Their ability to remove large dust Ioads on a non-selective basis has made them essential for many applications.
GEA’s unique Low-Pressure High-Volume Technology is especially applicable for treating large gas flows and achieves nearly zero emissions with the lowest cost of ownership. The GEA ECOpuls Filter (Elliptical COncentrical puls Filter) combines the dedusting performance of conventional bagfilters with the reliability, extended lifetime and energy saving capabilities of low-pressure cleaning technology.
This bagfilter technology has been optimized for large volume flows and requires a minimum of pulse air equipment.
A reduced amount of individual parts, its high gas-cleaning efficiency and the plant’s small footprint call for a minimal investment for the GEA ECOpuls filter solution.
Thanks to GEA´s low pressure technology, the air used for bag cleaning needs to be compressed to only 0,8 bar (g). This low compression rate is achieved through reliable and energy efficient root blowers instead of using a conventional high/medium pressure system with a substantially higher energy consumption.
The low overall pressure drop of the GEA ECOpuls filter and the extended filter bag lifetime help reduce further operational costs.
As a result, the GEA ECOpuls filter is not only technologically superior, but also offers the lowest cost of ownership.
The Bagfilter can be carried out with multiple compartments to enable on-line maintenance as well.
The ECOpuls Filter is ideally suited for its combination with other emission control tasks like the separation of SO2, Mercury and NOx.
Changes in the upstream process or lower clean gas dust loads often lead to switch from a dry electrostatic precipitator (ESP) to a Bagfilter. GEA is an expert for such Bagfilter components´ retrofits installed in existing ESP casing.
When dust-laden gases flow through a porous layer of fabric or felt, the dust is separated from the carrier gas and deposited on the filter medium. It is re-moved periodically and falls into the dust hopper.
The filter materials used are woven or non-woven fabrics made from natural or man-made fibers as well as inorganic fibers (glass, mineral or metal fibers). A detailed description of the working principle can be watched here:
GEA has been building electrostatic precipitators for cleaning industrial process for over many years. Well over 12.000 units have been supplied to firms all over the world. Being the air pollution control technology supplier of choice, GEA offers innovative system designs, state-of-the-art microprocessor controls and constantly upgrades and rebu...
GEA high-temperature filters with ceramic elements to remove particulate matter and acidic gases. With very low dust emissions and thermally stable under high operating temperatures. No cooling of flue gases are required and no thermal heat energy is wasted when implementing them.
Companies like GEA process and store large amounts of sensitive data. However, security incidents, from ransomware attacks to physical intrusions and industrial espionage, are ever-expanding. GEA’s effective protection of its business partners’ data – as well as its own proprietary information – is evolving into a competitive advantage. We spoke with Iskro Mollov, GEA’s Chief Information Security Officer, about what it takes to protect a global business in a volatile world.
Resource-efficient fashion has been a long-sought ambition amid the fashion industry’s considerable contributions to global carbon emissions. The need to close the loop by recycling textile fibers into virgin-like materials is higher than ever but seemed like a distant dream until now: Circ, GEA’s American customer and pioneer in the field of textile recycling, might be rewriting the future of the fashion industry.
Alternative proteins are promising – yet still expensive to produce. The usual response is that scaling up will solve this issue. But what if the solution was really about getting better, not just bigger? From more efficient, high-yield processes to upcycling waste heat, engineers are reshaping how we grow food.
