NATURAL GAS

Natural Gas processing plants depend highly on adsorbents to help remove impurities and other material to achieve required levels of purified natural gas. Depending on the composition of the feed stream and the demands of the final product, our adsorbents offer a variety of material selection for the ideal result needed.

Dehydration

Water must be removed to a certain level before moving to the cryogenic NGL extraction process for prevention of stream freezing up and plugging the cryogenic piping.

Products:
· HYD03C
· HYD03B
· HYG04DG (4×8, 8×12)

Gas Sweetening (H2S removal)

Composition of H2S in Natural Gas feed streams can vary from different places but should always meet the requirement levels of 4 ppm or less.

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.

Products:
· HYG04DG (4×8, 8×12)
· HYD05C
· HYD10A (4×8, 8×12)

CO2 removal

Carbon dioxide must be removed from stream to meet typical requirements of less than 50 ppm for NGL and LNG production.

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.

Products:

· HYG04DG (4×8, 8×12)

Mercury Removal

Mercury in a natural gas stream can have undesirable consequences. Removing mercury protects the heat exchanging cold box from corrosion and allows the gas to meet environmental regulations while increasing overall product stream value.

Products:
·
 HYG03Ag
· HYG10Ag

Nitrogen Rejection Unit

Nitrogen Rejection Unit Pipeline standards require natural gas to contain less than 4% of nitrogen. Nitrogen rejection units require adsorbent to remove the necessary nitrogen in order for natural gas pipeline transport.

Products:

· HYD10A (4X8, 8X12)
· CMS (200, 220, 240, 260)

REFINING

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.

LPG Sweetening

Liquefied petroleum gas contains sulfur compound impurities like H2S, COS, and mercaptans that must be removed before further processing.

Removes: water (H2O), carbon dioxide (CO2), sulfides, mercaptans, and more

Catalytic Reforming

Adsorbents are needed to remove chlorides in catalytic reforming processes to minimal levels and prevent the corrosion or poisoning of costly downstream catalysts.

PETROCHEMICALS

Petrochemical plants process hydrocarbon and olefin base feed streams that must go through extensive treatment to produce a variation of products. Our adsorbents are designed to help remove necessary material to meet required specifications. Impurities that are commonly removed in these streams can range from oxygenates, sulfur compounds, water, and others.

Ethylene Purification (Removal of CO2, H2S, H2O, methanol, etc.)

Ethylene contains traces of (CO2, H20, methanol, etc.) that must be removed in order to move on to the polymerization process.

Products:

· HYG04DG (4×8 and 8×12)
· HYD05C
· HYD10A (4×8 and 8×12)

Cracked Gas Drying

Cracked gas produced from ethylene plants is water saturated that must undergo drying with a molecular sieve before further processing.

Products:

· HYD03C
· HYD03B

Olefin Treating

Olefinic feed streams contain toxic and harmful impurities that must be accounted for to help prevent equipment damage and life.

Products:

· HYD05C
· HYD10A (4×8 and 8×12)

RENEWABLE FUELS

Renewable fuels include liquid and gaseous fuels, that come from renewable feedstock sources. These fuels must undergo different types of treatments to achieve purity level requirements.

Ethanol Dehydration Units

Products for Ethanol Dehydration Units:
· HYD03C

HYD03C is a molecular sieve that is specifically designed for Ethanol Dehydration Units and differs from standard molecular sieves by offering an advantageous balance of crush strength, adsorption capacity, and minimal 
co-adsorption properties. HYD03C has a superior selectivity between water and ethanol molecules, which increases both efficiency and dehydration capacity each cycle to help plants meet production goals and maximize output. This product is suitable for both pressure swing adsorption and temperature swing adsorption processes. Once ethanol has been dehydrated, it can then be applied in bio-fuels for direct blending and ETBE production, or for other uses such as in chemicals, food industry, pharmaceuticals, and more.

· HYG04DG (4×8, 8×12)

Landfill Gas (H2S & Siloxane Removal)

Products for Landfill Gas:
· HYD10A (4×8, 8×12) – Siloxane Removal

Removing siloxane is an important step in cleaning methane gases for use as fuel since siloxane is a form of crystalline silica that will essentially turn into glass when burned or combusted. The collection of combusted siloxanes inside of engine components can cause the buildup of heat, water, and other contaminants that can cause corrosion, leading to problems in the engine.

Removal of H2S is a critical procedure that helps reduce corrosion for power generation equipment, pre-treat LFG for high-BTU gas processing, and to reduce sulfur oxides (SOx) emissions, associated with LFG combustion.

· HYAS200 – H2S Removal

HYAS200 is a special adsorbent that is a smooth, spherical adsorbent which has demonstrated its superior performance applied in the selectivity of removing COS, H2S, CS2 and any other mercaptans impurity from hydrocarbon streams. Removes H2S from following sources:

• Biogas that originates in sewage treatment plants due to anaerobic conditions in sludge
• Agricultural biogas
• Gases from anaerobic industrial sewage treatment facilities
• Landfill gas
• Industrial combustion and synthetic gases
• Waste and co-fermentation plant biogas after anaerobic digestion
• Miscellaneous H2S containing industrial exhaust gas (i.e. paper industry, oil-mill applications)
• The treatment of H2S containing exhaust from industries and wastewater treatment facilities

Hydrogen Purification

Products for Hydrogen Purification:
· HYD05C
· HYD10A (4×8, 8×12)

HYD05C & HYD10A molecular sieve are the adsorbents available that can achieve high purification levels of Hydrogen. These particular adsorbents remove common impurities found within hydrogen streams in steam methane reforming processes. Although both sizes can get the job done, for high production volumes of Hydrogen fuel HYD10A would be recommended over the HYD05C (due to higher quality and better sustainability over time). These adsorbents are either used in Thermal Swing Adsorption Units (TSA) or Pressure Swing Adsorption Units (PSA) in order to achieve the desired gas separation.

AIR SEPARATION

Adsorbents are used in a range of air separation, purification, and compression applications. Air must go through separation processes to obtain valuable gases at a purity level that must be met whether its oxygen or nitrogen. Argon and other gases in air must be treated to achieve requirement of impurity levels.

Medical Oxygen Generation

Oxygen tanks and concentrators require adsorbent to treat the air that is flowing in to achieve 90-95% oxygen purity.

Products:
· HYGB100D (20×35)
· HYGB100N  (20×35)

Industrial Oxygen Generation

Extreme cryogenic conditions force the manufacturing process to remove all impurities such as water vapor, CO2, and certain heavy hydrocarbons in order to prevent stream from freezing and plugging the cryogenic piping.

Products:

· HYD10A (4×8, 8×12)
· HYGB100C (10×16)
· HYDB100G (8×12)
