Industrial Gas Activated Carbon

Active Carbon is a key component in cleaning industry, providing a dependable way to remove sulphur, mercury, VOCs, and other microcontaminants in the flow of the process.

What Is Industrial Gas Activated Carbon?

AFCO is a specially designed class of active carbon that is used during the entire manufacturing, treatment and cleaning of the industrial gas to eliminate pollutants that threaten the efficiency of the process, destroy the downstream facilities, poison the catalytic converter, and impede the compliance of the treated gas with the purity criteria of the product.

The process of industrial gas – which comprises hydrogen, natural gas, synthetic gas (syngas), nitrogen, CO2, and LPG (LPG) – is seldom clean at the place of manufacture. They have different concentrations of sulphur (H₂S, COS, thiol), Hg, As, Chlorine, Chlorine, Volatile Organic Compounds (VOCs), as well as other micro-contaminants, which need to be cut down to parts per trillion in order to ensure safe treatment, transportation and sale. Not only are these pollutants a matter of quality – they are irreversible deactivation of valuable metallic and base-metal catalysts for downstream reformation, hydrogenation, and synthetic reactions, resulting in disastrous process losses that greatly exceed those associated with upstream purification.

Active carbon solves this problem by combining physical absorption and — in the case of an impregnated grade — chemical absorption, providing pollutant removal performance that no other single material solution could match across the entire range of industrial gas cleaning needs. The ability to adapt to a variety of gas components, working pressures, and temperature conditions has enabled it to be the preferred material in the world’s most demanding sectors.

Key Advantages of Industrial Gas Activated Carbon

The selection of appropriate active carbon levels for industrial gas cleaning will have a direct impact on the lifetime of the catalyst, on the purity of the product, and on the economy of the whole process. HPC Active Carbon Provides Measurable Benefits at All Key Phases of Cleaning:

Effective Sulfur Compound Removal at Trace Levels: Active carbon - especially sulphur - dipped and potassium iodide - enables the profound elimination of H₂S, COS and thiols to below ppm, thereby protecting valuable metallic catalysts from irreversible sulphur toxicity in the downstream reformer, the fuel cell and the hydrophile.
Mercury and Heavy Metal Capture: Special sulfur immersion active carbon is an industry standard for removing Hg from the supply flow of natural gas and LNG, reaching a level of less than 0.01μg/Nm3 – a minimum level needed to prevent the melting of low temperature aluminium heat-exchangers from mercury fusion and catastrophic failure.
Broad VOC and Hydrocarbon Adsorption: Due to its large surface area and adjustable pore structure, it is possible to efficiently adsorb a broad range of VOC and LHC from the gas flow, thus avoiding pollution in the downstream market, pollution of the product and the emission limit.
Compatible with High-Pressure Fixed-Bed Systems: High quality column and granular active carbon grades designed for commercial gas use retain structure integrity and low-pressure-drop properties at high working pressure typically associated with an industrial gas treatment facility, guaranteeing a stable long term performance with no channeling or mechanical wear.
Versatile Across Multiple Industrial Gas Applications: Starting from the cleaning of hydrogen and natural gas to the treatment of syngas and the production of nitrogen, Active Carbon provides a uniform and specific treatment efficiency for a wide variety of industrial gas treatment settings and contamination profiles.

Because of these properties, active carbon has become an essential frontrunner in the world’s industrial gas value chain – from well head air conditioning to super high purity speciality gas.

Industry Challenges About Industrial Gas Activated Carbon

Sulfur Compounds Irreversibly Poison Downstream Catalysts

Even tiny amounts of H₂S, COS, and thiols in the parts per million range are able to cause permanent deactivation of valuable metallic catalysts for reforming, hydrotreating, and ammonia-synthesizing reactors.

Mercury Poses Catastrophic Risk to Cryogenic Equipment

Mercury presence of Hg in the NG and the LNG inlet flows is combined with the aluminium heat-exchangers of the low temperature treatment facility, which leads to the expensive shutdown of the facility, the large-scale replacement of the equipment and the severe security events.

Carbon Bed Breakthrough Causes Costly Process Disruptions

In an ongoing process of producing natural gas in an industry, unforeseen levels of carbon saturation and contamination will cause unscheduled CCS shutdown, which will upset the downstream generation plans and cause substantial economic damage far exceeding the actual price of carbon.

Specific Use Scenarios — Biogas Activated Carbon

Hydrogen Sulfide (H₂S) Removal

Hydrogen generated by vapor methane reforming (SMR), coal-gas gasification, or electrolysing comprises microamounts of sulphur compounds — especially H₂S and COS — which have to be eliminated to below 0.1 parts per million in order to make it usable for a fuel cell, a hydrocracker, or a semiconductor fabrication process. Active carbon, especially sulphur impregnated and potassium iodine-impregnated grades, offers a profound desulfurizing capability in a protective bed arrangement upstream of a valuable metallic catalyst to avoid irreversible sulfides and to preserve long term activity and selectivity of the downstream process catalysts.

Natural Gas Sweetening and Mercury Removal

The crude gas drawn from the reservoir is commonly found in the presence of H ₂ s, thiols, and Hg in excess of the standard of the pipe, which is a major hazard to the downstream treatment facility. Sulfur-impregnated Active Carbon is an industry standard for removing Hg from the supply flow of natural gas and LNG, with an exit Hg of less than 0.01μg/Nm3 to prevent the melting of low temperature aluminium heat-exchangers. Granular ACCC also offers efficient thiol and light-sulphur composite polishing before the MGC.

Synthesis Gas (Syngas) Conditioning

Syngas generated from coal, biomass, or gas gasifications for the purpose of synthetic ammonia, methanol, or Fischer-Tropsch fuel production includes sulphur, chloromethane, and microamounts of heavy metals which have to be eliminated prior to coming into contact with a synthetic catalyst. Active Carbon Guard Beds located upstream of the Synthetic Circuit are able to capture such Catalyst Toxins at Trace Concentration Levels, Prolonging Catalyst Lifetime, Decreasing Catalyst Substitution Rate, and Preserving Economic Viability of Large Scale.

CO₂ Purification for Food-Grade and Industrial Applications

The CO₂ for the production of foodstuffs and drinks, the treatment of drugs, and the enhancement of oil production has to comply with strict purity standards for VOCs, sulphur compounds, acetaldehyde, benzenes, and other micro-organic pollutants. Active carbon polishing beds – located at the end of CO ₂ liquefaction and cleaning trains – absorb such microcontaminants to a level lower than the detection threshold, allowing CO ₂ manufacturers to ensure that their products comply with food grade criteria, including ISBT and NSFC rules.

Nitrogen and Inert Gas Purification

High pure nitrogen is needed to remove remaining oxygen, water, hydrocarbons, and VOC residues in semiconductor manufacturing, electronic production, drug packaging, and chemical coating, which could endanger the integrity of the product or its technical properties. Active Carbon Polishing Phases, which are incorporated in the Nitrogen Generating and Purifying Systems (PSA) and Low Temperature Air Separation Devices (HPS), Low Temperature Isolation Devices (HPS) and Low Temperature Air Separation Devices (HPS), which will guarantee that the nitrogen is pure enough to comply with the parts per billion required for electronic and pharmaceutical end-users.

LPG and Hydrocarbon Gas Purification

LPG (LPG), propane, butane, and other light-hydrocarbon gas flows, which are used as fuel, petroleum-based raw materials, or aerosol propellants, shall not contain sulphur compounds, thiols, and fragrances which may lead to the smell of the product, the corrosion of the downstream facilities, and the pollution of the catalytic agent in the petrochemical plant. Active Carbon Treating Systems – Working in Vapor Phase and Liquid Phase – offer efficient Sulphur and Thiols Removal from LPG Flow to Meet Product Specifications and Safeguard Quality and Merchantability of Refined Hydrocarbon Products.
