Indirect adiabatic cooling: an energy-efficient solution for industry

In the face of rising global temperatures and the challenges posed by global warming, traditional cooling methods – often energy-hungry and unsustainable – are no longer sufficient to meet the growing needs of business and industry. In this context, indirect adiabatic cooling is positioned as an innovative, energy-efficient solution, capable of reconciling employee comfort, energy savings and respect for the environment.

What is a reversible adiabatic transformation?

The reversible adiabatic transformation is an idealized thermodynamic process that plays a central role in the analysis of energy systems. Excluding any heat transfer with the outside world, this transformation is governed solely by the laws of thermodynamics and the equations of state.

VOC and dust emissions by sector

Volatile Organic Compounds (VOCs) and dust are key pollutants in many industrial sectors, with environmental implications and health risks.

Obera Website Banner: VOC Hazards

How to deal jointly with VOCs, dust, odors and ATEX risks in industry?

Many industrial operations produce an atmosphere laden with dust and Volatile Organic Compounds (VOCs). Or because the operation simultaneously emits these dusts and VOCs. Or because the workshop or industrial shed houses parallel operations that independently generate dust or VOCs, which then mix with the ambient air.

How to effectively extract VOCs from solvents?

Volatile Organic Compounds (VOCs) encompass thousands of chemical substances contained in the products, accessories and equipment present at workstations on an industrial site. Among the products used or manufactured by industry, solvents in particular emit vapors and aerosols made up of VOCs.

What processes improve air quality by eliminating VOCs?

wo families of VOC treatment processes extract VOCs from ambient air:

Recovery processes

Recuperative processes aim to capture VOCs for reuse. They include adsorption with desorption, absorption, condensation and membrane separation.

What sources of VOCs contribute to poor air quality on an industrial site?

As several thousand chemical substances meet the definition of VOCs, the sources of VOCs on an industrial site are very diverse. Source classification helps to identify VOCs.

A distinction is made between primary and secondary sources of VOCs. The first are those emitted directly into the air. The latter produce VOCs through chemical reactions between compounds already present in the air.

How do you maintain your industrial dust collector?

An industrial dedusting system is an essential piece of equipment for controlling dust emissions in industrial plants. Preventive maintenance is the key to ensuring efficient operation and prolonging the life of this equipment. The dust collector is the most important component of a dust collection system. To keep a dust collector in good working order, it’s important to regularly check and maintain certain key parts.

Dust removal process and risk of explosion or fire

Dust collectors are used to prevent the risk of fire and explosion in industrial processes involving the suspension of very fine particles. But these risks are often transferred to the dust collection system, which sucks up and filters combustible dust. Preventive and protective measures must therefore also be applied to the dust collection system.

Industrial processes and prevention of explosion or fire risks using industrial dust collectors

Many industrial systems use flammable powders or produce combustible dust. The operation of these production systems entails risks of fire and explosion. Risks deriving from the characteristics of the products and processes used. That’s why legislation on worker safety and environmental protection requires companies to install appropriate prevention and protection systems. The most common preventive measure is to control the suspension of particles and their concentration in the ambient air or in equipment. These are met by suction and filtration systems designed to remove dust from processes.

Fixed or mobile, central or local dust collector: which criteria to choose?

While the choice of a dust collection technique is guided by the size of the particles emitted, their physico-chemical properties, and their impact on operators and the environment, other criteria are involved in the choice between a fixed or mobile dust collector, and between centralization or localization of the dust collection system. These criteria depend on the production context: the industrial sector, the size of the production unit, the point in its life cycle, the production processes, the legal constraints governing its operation, the financial balance between budgetary constraints and the investment and operating flows of the dust collector, etc. Each case is unique. The criteria are numerous! A first approach will enable you to clear the ground!

Industrial dedusting technologies

There are two main dust removal routes: dry and wet. The dry process includes dust collectors with filter layers (bag filters, pockets, cartridges), mechanical (cyclones) and electrostatic (electrostatic precipitators); the wet process includes scrubbers, venturi scrubbers, bubble columns and wet electrostatic precipitators. The choice of technology depends on expected performance, budgetary constraints and the industrial processes to be dedusted, in particular the size of the particles emitted.

What is explosive dust extraction and removal?

This refers to the process of cleaning and removing flammable or explosive dust present in various industrial environments. Explosive dusts are fine molecules that can accumulate in the air or on surfaces and present a serious threat of explosion or fire if they come into contact with a source of ignition, such as a spark or open flame.
