VDI 2441 2016-05 PDF

Full title and description

STB VDI 2441 2016-05 — Process gas and waste gas cleaning by cold plasma: Barrier discharge, corona discharge, UV radiation. This guideline covers the use of non‑thermal (cold) plasma and UV processes for the destruction of gaseous contaminants and odours in process and waste gas streams.

Abstract

The guideline describes fundamentals and practical guidance for planning, construction and operation of non‑thermal plasma and UV‑based exhaust‑gas cleaning systems. It emphasises applications for odorous gases and exhausts containing relatively low concentrations of gaseous hydrocarbons, and explains the role of electron energy in breaking down hydrocarbons while the bulk gas remains near ambient temperature. Practical aspects such as system design, performance expectations, and typical application limits are addressed.

Scope

VDI 2441 provides guidance for exhaust‑gas cleaning systems that use non‑thermal (cold) plasmas (barrier discharges, corona discharges) and UV radiation to decompose gaseous pollutants. The scope includes technical principles, applicability (notably for odour control and low‑concentration VOC streams), and recommendations for planning, construction and operation of such systems. It is intended to help designers and operators assess suitability and expected performance of plasma/UV solutions for process and waste gas treatment.

Key topics and requirements

• Fundamentals of non‑thermal (cold) plasma and electron‑driven chemistry.
• Descriptions of barrier discharge and corona discharge technologies and UV‑C irradiation techniques.
• Guidance on system planning, reactor design and integration into exhaust lines.
• Operational considerations: energy input, gas throughput, maintenance and monitoring.
• Performance expectations and applicability limits (typical focus on odours and low‑concentration gaseous hydrocarbons).
• Safety, material compatibility and handling of by‑products/secondary emissions.

Typical use and users

Typical users are environmental and process engineers, plant designers and manufacturers of abatement equipment, facility operators (chemical, food, waste‑treatment and other industries with odorous or VOC‑bearing exhausts), regulatory compliance specialists, and researchers developing or evaluating plasma/UV abatement technologies.

Related standards

VDI 2441 is published as part of the VDI/VDI‑DIN collection on air pollution and waste‑gas cleaning; related VDI documents and handbooks on waste‑gas cleaning (for example VDI/DIN manuals on abatement technologies and other VDI guidelines for catalytic, thermal and biological waste‑gas cleaning) provide complementary methods and requirements. The 2016 edition replaces an earlier 2014 version.
