Water Treatment
Axens activated alumina is widely utilized in various water treatment applications due to its exceptional adsorption properties. It absorbs harmful chemicals and ions such as chlorine, arsenic, fluorine and sulfur to keep drinking water safe for consumption. Inoltre, this material displays excellent tolerance to thermal shock, abrasion and liquid immersion without shrinking or swelling under pressure; making it suitable for natural gas processing as well as corrosion.
Not only can our adsorbents remove harmful toxins and substances from the environment, they also play a crucial role in conserving it by decreasing landfill space requirements. Axens activated alumina is widely used to treat groundwater contamination as well as municipal wastewater treatment facilities, storm water management systems and agricultural effluent.
Activated alumina is an extremely efficient solution for purifying polluted water that contains heavy metals or other pollutants, typically by reducing contamination levels to acceptable EPA standards before use can resume for drinking or other purposes. Once contamination levels have been reduced to safe levels, periodic testing should be conducted to ensure continued proper functioning.
Alumina industry participants strive for product differentiation and innovation to increase market share. Inoltre, increasing environmental regulations drive a desire for eco-friendly production methods, increasing demand for eco-friendly alumina products with less environmental impact.
Gas & Liquids Treatment
Demand for activated alumina will continue to be driven by global oil and gas production growth, leading to the need for treating gases, liquids and water. Activated alumina is an outstanding gas and liquid adsorbent due to its high pole molecular absorbent characteristic, large surface area, strong resistance against thermal shock shockwaves, great selectivity characteristics, mechanical strength characteristics as well as its low permeability properties.
As opposed to other adsorbents that may become polluted with the substances they’re meant to absorb, axens activated alumina remains chemically inert towards all commonly-occurring solvents, acids, and bases – making it the ideal choice for harsh environments such as hospitals. It can even resist abrasion and high temperatures without becoming damaged from its duties!
Due to their highly reactive properties, sulfur species like hydrogen sulfide (H2S), carbon dioxide (CO2), mercaptans and sulfides are highly corrosive and must be eliminated from various gas and liquid streams to meet fuel gas, syngas pipeline specifications, LNG and LPG specifications.
Axens offers both regenerable and single use activated alumina products for gas and liquid treatment applications, such as molecular sieves and milled or granulated activated alumina. We tailor them specifically to the requirements of each application – be it fluoride removal from drinking water, desiccation of liquids and gasses in vacuum systems, catalyst support or bio ceramic applications that require resistance against acidic or alkaline conditions.
Catalytic Reforming & Isomerization
Axens is a leading supplier of technologies, catalysts and adsorbents to industries including oil refining, petrochemicals, gas, renewable fuels and alternative fuels, water treatment as well as wastewater. Their process licensing capabilities range from basic engineering design, training and start-up support for single unit overhauls up to large grassroots complexes.
Adsorption of contaminants on alumina is used extensively across many industries. Refineries utilize it for catalytic reforming and isotherization (the formation of isomers). Here, the alumina acts as a sorbent which prevents contamination due to liquid carry-over, caustic soda residues, corrosion inhibitors and heavy metals from fouling their catalyst.
Molecular sieve adsorbents are widely utilized in gas drying applications to avoid the formation of hydrates and free water condensation, with their high dynamic water adsorption capacity and excellent mechanical properties enabling them to meet stringent specifications required by natural gas systems.
Axens’ milled alumina powders are widely recognized for their outstanding performance in water treatment applications for chlorine, arsenic, fluorine and sulfur removal. Inoltre, these materials offer some of the best mercury adsorption properties available and are the premier material available for decomposition furnace adsorption. In terms of dynamic moisture removal properties these aluminas feature high porosity with ideal pore distribution that offers high dynamic capacity to remove moisture quickly – in combination with crush strength resistance attrition resistance regeneration efficiency they make them suitable for operating conditions found in air drying and gas treatment applications.
Fluoride Removal
The global activated alumina market is highly concentrated, with few vendors commanding substantial market shares. Major players are expanding their product lines and regional presence through acquisition and product diversification strategies. Major market players include BASF SE, Devson Catalyst, Camfil Group, Evonik Industries AG, JM Huber Corporation Porocel Industries LLC Sumitomo Chemical Co Ltd KIN Filter Engineering Co Ltd Dynamic Adsorbents Inc and Sorbead India are some of these key participants.
Fluoride removal is an integral component of activated alumina’s role in the oil and gas industry. Hydrogen Fluoride alkylation units use Hydrogen Fluoride to catalyze light olefins (C3 and C4) into an alkylate component which is blended into gasoline pools to increase octane number. Unfortunately, this process generates significant amounts of fluorinated hydrocarbons which must be eliminated to protect downstream equipment as well as meet relevant specifications levels.
To meet our clients’ requirements, AxTrap 612 from Axens is an innovative high-performance fluoride-trapping material with unique properties designed specifically for fluoride removal from effluent streams in HF alkylation units. Isotherm testing on AxTrap 612 demonstrated its ability to meet fluoride specifications; further column tests comparing AxTrap 612 against quarry sand and fill were carried out to simulate reactive backfill using PRBs or reactive backfill systems; results showed that over 65% of fluorides were irreversibly bound at pH 9.5 as evidenced in previous studies.
