APPLICATIONS

OUR SYSTEMS IN APPLICATION

With our plants, we use thermal, chemical, biological and physical methods to clean exhaust and waste gases from:

 

DUST

  • There are various types of dust: sticky, wet, dry or flammable. Dust also differs in grain size, material composition and concentration.
  • The principle of dust minimisation for the environment applies - protection against immissions and emissions, e.g. at the workplace
  • The regulations of TA-Luft serve as the legal basis
  • Wessel offers various solutions for reducing the dust load and for all types of dedusting - wet or dry

Do you have any questions on wet and dry dedusting? If you have any questions or are interested, please do not hesitate to contact us! We look forward to hearing from you:

ODOUR

  • Odor emissions can cause a significant nuisance in the neighborhood
  • The required level of odor reduction is prescribed by law in most countries. In Germany, it is formulated as a goal of the Federal Immission Control Act
  • The exact requirements for permissible odor emissions and the limits of acceptable odor immissions in Germany are regulated in more detail in the GIRL. In the future, it is expected that these requirements of the German directive will be included in the TA-Luft
  • Odor is often a mixture of substances and therefore results as a cumulative effect of a large number of odorous individual substances. It is not uncommon for there to be several hundred individual substances and gases of widely differing concentrations and properties (water-soluble/non-water-soluble hydrocarbons, chemical substances, etc.).
  • As diverse as the individual substances of the odor are, so are the technological possibilities for odor reduction
  • Commonly used odor removal processes include bioscrubbers, biofilters, adsorbers, chemical scrubbers, or thermal systems
  • Odor concentration, hedonics and odor characteristics also derive from complex interactions of the individual substances, achievable removal efficiencies of different exhaust air purification technologies can only very rarely be predicted with the known process engineering calculation models. Therefore, it is often advisable to carry out tests with a suitable exhaust air purification system in advance
  • With our process engineering test plants and more than 250 supplied large-scale exhaust air purification plants alone for odor removal in a wide variety of industries and very different odorous exhaust air compositions, we have the necessary competence and experience in this field

SOLVENT - VOC / TOC

  • VOC: Volatile Organic Compounds (VOCs)
  • The term solvent covers irritating, allergenic or even carcinogenic substances, with usually very different degrees of harmful effects for humans and animals as well as the entire environment
  • Solvents are often contained in varnishes, paints, resins or adhesives and are released during drying processes or also during biological processes such as waste treatment
  • Depending on the concentration and water solubility of the VOCs and taking into account all economic advantages, we clean the exhaust air using biological, chemical or thermal methods - in some cases also in combination with adsorption processes.

POLLUTANTS

  • Pollutants can be defined as all organic and inorganic compounds that are often odorous and have a harmful effect on humans and the environment
  • Typical pollutants are volatile chemical substances from production processes such as formaldehyde and other aldehydes, ammonia, hydrogen sulfide (H2S) or acids (HF, HCl)
  • Wessel offers turnkey plant systems made of a wide variety of materials tailored to the specific application (including various stainless steels or plastics) or plants with special coatings to separate the pollutants
