Petroleum & Gas
The petrochemical industry encompasses numerous applications of activated carbon, with Haycarb products widely recognized for their effectiveness in oil and hydrocarbon sweetening by removing contaminants such as mercaptans. As a leading provider of activated carbon for petroleum, we offer specialized low-silica products for boiler condensate de-oiling and purification, as well as tailored solutions featuring selective adsorption and desorption properties for pressure swing applications.
Our products are also sought after for gas scrubbers to efficiently eliminate Hydrogen sulfide (Hâ‚‚S) and carbon dioxide (COâ‚‚) from the process feed, enhancing its anticorrosive properties and thermodynamic stability. In the production and purification of natural gas, Haycarb Activated Carbon products work to remove sulfur compounds, mercury, organic contaminants, and other impurities found in gas streams.
Hydrocarbon Sweetening
Hydrocarbon sweetening is a process that removes sulfur compounds from hydrocarbon streams, such as natural gas, gasoline, and other petroleum products. This process improves the odor of these substances and reduces their corrosiveness and toxicity. Sulfur compounds, including hydrogen sulfide (Hâ‚‚S) and mercaptans, not only emit unpleasant odors but can also produce hazardous sulfur dioxide (SOâ‚‚) when burned, posing a threat to the environment. These gases also corrode gas pipelines and are toxic to humans.
Haycarb provides industry-recognized granular activated carbon (GAC) and extruded pellet carbon for hydrocarbon sweetening. Our products are engineered to act as catalytic carriers, enhancing the sweetening process and removing mercaptans and other sulfur-containing compounds from refinery products. Additionally, our activated carbons can further adsorb trace contaminants in the hydrocarbon mixture, ensuring thorough purification.
Pressure Swing Adsorption
Pressure swing adsorption (PSA) technology separates individual gases from a mixture under pressure. This process takes advantage of the varying affinities of different gas species for an adsorbent material and their molecular characteristics. Activated carbon is used in the pre-filtration of the air streams in these applications.
Haycarb’s premium activated carbon products are utilized in various pressure swing adsorption applications, including large-scale commercial hydrogen synthesis for carbon dioxide removal, hydrogen sulfide removal in oil refineries, nitrogen separation from methane in methane gas processing plants, and ammonia production.
Natural Gas Purification
Gas process streams frequently have undesirable or harmful contaminants that must be eliminated prior to use. Activated carbon technology offers the most cost-effective purification methods for this purpose. Specialized activated carbons can be utilized to desulfurize gases like ethylene and natural gas.
Haycarb offers activated carbon products designed to effectively remove sulfur compounds, mercury, organic contaminants, and other impurities from natural gas streams. Our specialized sulfur-impregnated pellet carbons are widely recognized in the industry for their exceptional mercury loading capacities.
Our carbons also contribute to reducing pollution from natural gas operations by addressing water contamination, by-product refining, and emissions of greenhouse gases, nitrogen oxides, sulfur dioxide, volatile organic compounds, and heavy metals.
Additionally, Haycarb Activated Carbons are employed in Absorbed Natural Gas (ANG) technology, which allows for efficient natural gas storage by storing methane at lower pressures. This leads to reduced compression and reduced storage costs while enhancing safety.
Vapor Recovery Units
Vapor recovery units (VRUs) control hydrocarbon vapors during gasoline storage and unloading by processing gas streams saturated with gasoline. These units require specialized adsorbents for effective treatment.
Haycarb has leveraged its in-house research, development, and engineering expertise to develop a specialized range of activated carbons designed for efficient adsorption and desorption of targeted molecules in vapor recovery units (VRUs).
Our activated carbon products effectively capture large quantities of gasoline from air streams while enabling efficient desorption mechanisms for reuse.
Beyond their superior adsorption properties, our activated carbons feature low dust levels and high intrinsic hardness, ensuring long-lasting, durable performance in gasoline recovery applications within VRUs.
Biogas Purification
Biogas primarily consists of methane and carbon dioxide, although it often contains impurities such as hydrogen sulfide (Hâ‚‚S), siloxanes, and volatile organic compounds (VOCs). These contaminants can lead to corrosion and deposits, decrease the efficiency of biogas utilization equipment, and pose environmental and health risks.
Haycarb’s specially treated pelletized activated carbon has a high surface area and an optimized pore structure, ensuring effective adsorption of these impurities. Haycarb provides customized activated carbon solutions for specific biogas purification needs, guaranteeing optimal performance for various biogas compositions and applications.
