Carbonology

When contaminants such as H 2 S and other odours need to be removed from an air or gas stream, it is important to select the correct activated carbon filter. The selection depends on several factors like: Flow rate; Concentration; Type of impurity; Superficial contact time; Location. The type of...

Introduction: What is bitumen? Ever heard of bitumen? Maybe… But what is bitumen exactly? Bitumen is a semi-solid hydrocarbon product produced by removing the lighter fractions (such as liquid petroleum gas, petrol and diesel) from heavy crude oil during the refining process. Bitumen and bituminous...

DESOTEC innovation: cost-effective hydrogen sulfide removal It is well known that every activated carbon will remove hydrogen sulfide from biogas to some extent. Hydrogen sulfide will adsorb on the internal carbon surface where it can be oxidised in presence of oxygen to sulphur. Ash constituents...

Hydrogen sulphide (H 2 S) is always present in biogas, although concentrations vary with the feedstock. The concentration of hydrogen sulphide in the gas is a function of the digester feed substrate and inorganic sulphate content. Wastes which are high in proteins containing sulphur-based amino...

Siloxane removal from biogas is imperative to guarantee a consistent performance of frequently used machinery like combustion engines, boilers, gas turbines, etc. Deposits of silica or silicates can cause these machines to wear off, apart from imbalances, fouls and other problems. But first of all...

Introduction It is a modern tendency in the chemical industry to continuously protect and improve the environment. Some companies apply more stringent measurements than needed to comply with the local environmental legislation. Styrene emissions can occur in the case of coating jobs. In situations...

A previous article explained that activated carbon can be defined as a crude form of graphite with a random or amorphous structure, which is highly porous over a broad range of pore sizes , from visible cracks and crevices to cracks and crevices of molecular dimensions. Activated carbon pores can...

What is activated carbon? Activated carbon (sometimes called activated charcoal) is a widespread adsorption media used in almost every industrial field. It is used in different applications such as purification (such as gas and water purification), recovery, decolourisation, deodorisation,...

Introduction DESOTEC activated carbon is a company already well established in the Benelux countries, France and Poland. As an internationally oriented company we continuously seek to improve our services to our customers and therefore decided to further expand in Southern Europe . As a result of...

Air pollution in the automotive industry One of the main factors influencing air pollution in automotive production is the generation of volatile organic compounds (VOCs) during the painting process. Automotive production being the production of cars, trucks, vans and busses. Several initiatives in...
