Cryogenic Air Prepurification

CryoDry Adsorbents – Molecular Sieve and more
Removes: water (H2O), nitrogen oxides, light weight hydrocarbons, and more
Air separation plants use cryogenic air separation technology to bring gas streams to extremely low temperatures, which allows plants to separate various gases by the condensation point. Gas that is cryogenically separated needs to have extremely low levels of water, carbon monoxide, and carbon dioxide in the stream to prevent freezing and blockage.

Desiccant Air Dryers

Desiccant Products – Activated Alumina, Silica Gel, Molecular Sieve, and more
Removes: water (H2O) and other contaminants
Desiccant dryers are used to dehydrate atmospheric air, or pure gases including H2, N2, O2, CO2, for use in pneumatic equipment. It is important for these gases to be purified and dehydrated before use to prevent corrosion and damage to machinery. Quality desiccants will offer an ideal combination of strength and adsorption capacity to produce high purity, dry air that can be trusted for use without causing damage to equipment.

Oxygen Generation

OxyFlo Adsorbents – Molecular Sieve: Type 5A, Type 13X, Specialized Types, and more
Removes: water (H2O), carbon dioxide (CO2), and other contaminants
PSA separation techniques replace the traditional cryogenic air separation because of its low investment, low energy consumption, and easy operation. Oxygen and nitrogen are separated, using molecular sieve, then oxygen or oxygen-enriched air is captured. This process works under the principle that molecular sieve for oxygen generation adsorbs nitrogen and oxygen at different rates in a certain pressure condition. Once separated, the oxygen stream can be used in various refining processes, as feed gas for pneumatic equipment, utilized for breathing oxygen, and for other industries that require high purity oxygen streams.

Hydrogen Purification

HydroFlo Adsorbents – Molecular Sieve, Catalysts, and more
Removes: water (H2O), oxygen, and more depending on product type
HydroFlo products are capable of generating high purity streams of hydrogen from an array of feed stocks, whether using atmospheric air to isolate hydrogen or purifying hydrogen from Steam Methane Reforming (SMR) feed, we will help select the ideal product for you.

Nitrogen Purification

NitroFlo Adsorbents – Molecular Sieves, Catalysts, Carbons, and more
Removes: water (H2O), oxygen, oil, organic particles, and more depending on the adsorbent type
Nitrogen can be produced using atmospheric air and can be either adsorbed or rejected during Pressure Swing Adsorption (PSA) processes to create a high purity stream. Our NitroFlo products are capable of generating high purity streams of nitrogen using a wide variety of different separation techniques. Whether you’re creating a nitrogen stream from atmospheric air or purifying an existing stream for high purity, we have the product for you.

Dehydration Units

EthaDry – Type 3A Molecular Sieve
Removes: water (H2O) to 1% or less
We considered the conditions that ethanol dehydration units require to operate at peak performance and designed a molecular sieve with ideal physical properties and selectivity to optimize productivity. This dehydration process creates a high purity ethanol that can be used for as fuel, in direct blending and ETBE production, chemical manufacturing, pharmaceutical production, use as a solvent, and more. This molecular sieve has a high selectivity for water over ethanol molecules, which can increase both operating efficiency and capacity.

Dehydration Units

WateRyd Adsorbents – Molecular Sieve and more
Removes: water (H2O) to less than 0.1 ppm
Powerful, dehydration grade adsorbents that deeply dry natural gas streams to prevent freezing before cryogenic separation. Both Type 3A and Type 4A are available for use, depending on the preference of operators and specific requirements of each plant. We also offer additional adsorbents for specialized processes such as Liquefaction, Peak Shaving, Hydrocarbon Dew Pointing, and more.

Sweetening

SulfuRyd Adsorbents – Molecular Sieve, Activated Alumina, and more
Removes: carbonyl sulfide (COS), hydrogen sulfide (H2S), carbon disulfide (CS2), and other sulfides and mercaptans
Our team of engineers will analyze your feed stream and select the ideal product for maximizing the value of your product stream. From molecular sieves, activated aluminas, and specialized sulfur traps, we will ensure you receive the best solution for your specific needs.

Nitrogen Rejection (NRUs)

NitroRyd Adsorbents – Product Information
Removes: nitrogen from hydrocarbon streams
Each operation is pretty unique, and our engineers will help you select the ideal product for your nitrogen removal needs. Whether a new build, or an existing application, we have the molecular sieves and activated carbons that you need to maximize your potential.

Mercury Removal

MercuRyd Adsorbents – Product Information
Removes: mercury from hydrocarbon streams
Specialized molecular sieves that are manufactured to selectively remove mercury from natural gas streams.

Petroleum Purification

Products for Petroleum Purification – Molecular Sieve, Activated Alumina, and more
Removes: water (H2O), carbon dioxide (CO2), sulfides, mercaptans, and more
Coming from a wide range of feedstocks, hydrocarbon streams can be filled with various impurities that need to be removed before the streams can be further refined. While much of the water and sulfur species that were originally present have already been removed, molecular sieves can be used to polish the stream to meet specification and increase the overall value of the product stream.

Catalytic Reforming

Chloride Adsorbents – Product Information
Removes: chlorides
Our chloride removal products include aluminas that optimize chemisorption properties of the alumina to offer an ideal product in catalytic reforming processes where catalysts are treated with organic chloride to enhance isomerization activity, promote surface acidity, and improve the qualities of the desired reformate.

Fluid Catalytic Cracking (FCCUs)

FCC Products – Catalysts and more
Function: catalysts to facilitate hydrocarbon chain cracking
Fluid Catalytic Cracking Units (FCCUs) are used to break, or crack, large hydrocarbon chains into smaller chains, which are suitable for use in gasoline blending. FCC is the most common catalytic cracking process and involves a catalyst section and a fractionation section.

Isomerization

Adsorbents for Isomerization – Product Information
Removes:  water (H2O), carbon dioxide (CO2), sulfides, mercaptans, and more
Specialized molecular sieves that are manufactured to selectively remove mercury from natural gas streams.

Steam Methane Reforming

HydroFlo Adsorbents – Molecular Sieve, Catalysts, and more
Removes: water (H2O), carbon dioxide (CO2), nitrogen, methane, and more
Steam reformers can be used in an array of applications including petrochemical refining, ammonia synthesis, chemical production, electronics manufacturing, and more. In petrochemical refining, hydrogen is used to refine crude oil to create high value fuels, such as gasoline and diesel, and can be used to remove sulfur from these hydrocarbon streams.

Olefin Cracked Gas Purification

These streams are dehydrated with molecular sieves that are built to selectively remove water but not olefins, which allows ethylene, propylene, etc. to remain in the process stream. Our product are capable of deeply dehydrating these olefin streams. OleCleanse is specially designed for purifying cracked gas streams and EthylCleanse is specially designed for purifying ethylene oxide, both offer high capacity for deep dehydration and contaminant removal.

Aromatics Purification

BTX aromatics include benzene, toluene, and xylene, which can be used to create dyes, detergents, and advanced polyurethanes for plastics and fibers.
