APPLICATIONS & SOLUTIONS
Breathing unclean air can pose dangerous health risks to the public and so it is vitally important that any industrial operations adhere to regulations related to their emissions to the atmosphere. As well as controlling emissions, industries often need to purify air and gas used in their processes so that contaminants do not create problems during their operations. Activated carbon is one of the most effective ways to tackle problems surrounding gaseous impurities in air and gases. Jacobi has a number of experts located in all geographical markets and each team is well-informed and experienced with the varying regulations of different countries and requirements of various processes.

Air Purification – VOC Removal
Volatile organic compounds (VOCs) are, unfortunately, widely present in the air we breathe. Some are naturally occurring and some are man-made. There are numerous different kinds and many varieties are harmful to both humans’ health and the planet. Any industrial activity that emits these compounds will need to comply with the stringent regulations that are in place to limit their levels in the air. Using activated carbon is an effective way to reduce levels of VOCs and ensure compliance.
Acid and Alkali Gases in Air Streams
Acid gases are collectively a particular type of inorganic gas containing significant quantities of hydrogen sulphide, sulphur dioxide or similar corrosive compounds.
Alkali gas is predominately ammonia but may also comprise sodium hydroxide fumes and odours from light amines. These gases can cause unpleasant odours and can be extremely toxic with effects ranging from eye irritation and headaches to respiratory issues.
Mercury and its reacted by-products in natural gas, petrochemical and refinery feed streams can result in extreme corrosion of metallic components. Mercury is, of course, highly toxic too. Jacobi has developed a series of high activity activated carbons that are chemically impregnated and are highly effective in removing mercury.
Desulfurisation of Natural Gas
Activated carbon adsorption is widely used to remove hydrogen sulfide (H2S), one of the major odorous compounds, from gas streams. Not only does it have an offensive odour, the gas is highly flammable and toxic too. Impregnated activated carbon has repeatedly shown the best performance in terms of removing H2S.
Pressure Swing Adsorption
High purity gases are increasingly used in food processing, refinery and industrial operations. In the petrochemical industry, remote extraction locations often dictate that gas generation occurs onsite. Activated carbon plays a vital role in the separation of oxygen, hydrogen and other critical gases from the air in pressure swing adsorption systems, allowing localised generation of these critical components for industries that need it.
Reformer Gas Treatment & Catalysis of Synthesis Reactions
The process of gas recovery often results in contaminants that are unfavourable to various treatment steps, such as precious metal catalysts. Activated carbons extend the life of these catalysts and can also perform a catalytic function for the manufacture of industrial products including phosgene, vinyl chloride and vinyl acetate. Jacobi offers activated carbon products which serve as effective all-purpose adsorbents for these applications.
