Boyce Activated Carbon Solutions For Refining Industries
The following discussion highlights these common applications and the solutions that Boyce Carbon can supply.
VOC Treatment & Control
Compliance with either the Benzene National Emission Standard for Hazardous Air Pollutants (NESHAP) regulation or local air emission regulations drives the need for VOC control at several emission points within the refinery, including:
Sewer pumps / junction boxes
Covered API separators and DAF units (level changes and diurnal breathing losses) Vacuum truck exhaust
Wastewater and storm water storage tanks (level changes and diurnal breathing losses)
Boyce activated carbon grades are particularly designed for these applications to be used in carbon adsorption units.
Vapor / Solvent Recovery
Activated carbon is often used in systems designed for the recovery of economically valuable products (gasoline vapors, benzene, and solvents) at refineries and terminals. Both pressure swing (for gasoline vapors) and temperature swing (for benzene and solvents) designs are commonly used. In this application, Boyce special grades of activated carbons with high working capacities allows for effective adsorption and desorption through numerous cycles.
Hydrogen Sulfide Removal
The processing of sour crude oil often results in the formation of hydrogen sulfide (H2S) at various points in the refinery.
Activated carbon is a common technology to control the nuisance odors and corrosion issues that often result from H2S. Boyce Specialty grades of carbon are often used to enhance the H2S capacity.
Amine Purification
Various alkanol amines are used by refineries to purify gas streams by removing acid gases such as CO2, H2S, and COS. During this process, the amine solution picks up hydrocarbons and organic acids.
Activated carbon is utilized to treat a slipstream of the amine solution to prevent buildup of these hydrocarbons, and provides several benefits to the refinery:
Improved amine scrubbing efficiency
Reduced corrosion rate
Reduced operating costs
Decolorization
Boyce Activated carbon is the perfect choice to remove unwanted color or other organic impurities from desired end products such as jet fuel, kerosene, gasoline, lube oil, and other products.
Boyce Granular activated carbon is produced from
coconut shell charcoal by the process of steam activation. It gives the necessary hardness to avoid excessive losses due to attrition and handling. They present large internal surface of pore structure, ensuring high adsorption power in specific purposes and uses. They are used in fixed or moving beds as columns where the liquid or gas passes through and gets purified. They can be used in liquid or gas phase continuous adsorption process and offer unusual economy in cases where carbon regeneration is favorable.
