Activated Carbon for Petroleum Refinery Wastewater Treatment - Heycarbons Manufacturer From China
Heycarbons is a professional activated carbon supplier for petroleum refinery wastewater, introducing carbon products, how activated carbon works in refinery wastewater and what contaminants it removes in this article.
Activated Carbon For Petroleum Refinery Wastewater
Petroleum refining processes generate large quantities of oily, high-COD, and highly toxic organic wastewater, containing oils, phenols, sulfides, ammonia nitrogen, and various recalcitrant organic pollutants.
As the oil refining industry is highly polluting, direct discharge of untreated wastewater will severely pollute rivers, lakes, and groundwater.
Utilizing a combined physicochemical, biological, and advanced treatment process can effectively reduce pollutant concentrations and achieve stable, compliant wastewater discharge.
Petroleum Industry Wastewater Advanced and Sustainable Treatment Methods:
Activated carbon adsorption can further remove residual organic pollutants, improve effluent quality, and promote water resource recycling and sustainable development.
Heycarbons Activated Carbon for Petroleum Refinery Water Treatment
Heycarbons activated carbon is widely popular among consumers due to its competitive price, stable product quality, availability, and fast delivery. For refinery wastewater treatment, the main types of activated carbon include coal granular activated carbon and powdered activated carbon.
Coal Granular Activated Carbon for Oil Refinery Wastewater Treatment
Coal-based granular activated carbon features a wide pore size distribution and abundant mesopores, making it suitable for adsorbing medium to large molecular weight organic matter. It can effectively remove COD, petroleum organic matter, phenols, polycyclic aromatic hydrocarbons (PAHs), recalcitrant organic matter, and color from refinery wastewater.
It possesses high mechanical strength, enabling it to withstand long-term, repeated flushing in a fixed bed. Its excellent wear resistance prevents it from being worn into fine powder, thus maintaining a stable bed structure and low operating pressure drop.
It is also cost-effective, making it the most widely used choice for refinery wastewater treatment. Heycarbons provides the following parameters for coal-based granular activated carbon for your reference:
- Size: 8-30, 12-40 mesh etc.
- Iodine value: 900-1100 mg/g
- CTC: ≥ 50-70
- Methylene blue: ≥150 mg/g
- Strength: ≥ 95-99%
- Ash: ≤ 10%
In addition, this type of coal-based granular activated carbon can also be used for demineralizated water pretreatment in refinery plant, which will be discussed later.
Heycarbons also provides modification treatments such as acid washing and impregnation according to customer needs and specific applications. Can also supply briquetted reagglomerated activated carbon.
Coal Powdered Activated Carbon for Effluent Treatment in Petroleum Refinery Project
Powdered activated carbon (PAC) from coal has an extremely large specific surface area and a very fast adsorption rate, making it primarily used for emergency or intermittent treatment of petroleum refinery wastewater.
It requires no fixed equipment and offers flexible addition. It can be directly added to the reaction tank, where it is stirred to ensure thorough contact with the wastewater, and then settled and removed along with the sludge. This makes it suitable for applications requiring rapid response to fluctuations in water quality.
Heycarbons provides the following specifications for coal powdered activated carbon for your reference:
- Iodine value: 500-1100mg/g min.
- Moisture content: 10% max.
- Methylene blue: 120-150mg/g
- pH: 8-11
- Ash: 8-20%
How Activated Carbon Works in Refinery Wastewater Treatment?
How activated carbon works in petroleum refinery wastewater treatment and what contaminants it removes?
Activated carbon is used in oil refinery wastewater treatment, primarily utilizing its highly porous structure and surface chemical properties to remove oil, organic pollutants, COD, color, and some recalcitrant substances from the wastewater through physical and chemical adsorption.
Activated carbon has a well-developed network of micropores, mesopores, as well as a certain proportion of macropores, resulting in a high specific surface area. Pollutants from the oil refinery wastewater enter the pores of the activated carbon and are adsorbed onto the surface and within the pores through van der Waals forces, thus being retained.
Coal-based activated carbon has well-developed micropores and mesopores, which can effectively adsorb small organic molecules and macromolecules of COD, as well as benzene compounds, color, phenols, sulfides, ammonia nitrogen, etc.
The surface of activated carbon usually has a certain degree of hydrophobicity and a strong affinity for non-polar oil molecules.
Activated carbon, with its graphite-like carbon layer structure containing π electrons, can form π-π electron interactions with the aromatic structures on its surface, typically exhibiting good adsorption effects on benzene series compounds (BTEX), phenols, and polycyclic aromatic hydrocarbons (PAHs) in oil refinery wastewater.
The surface of activated carbon contains hydroxyl (–OH), carboxyl (–COOH), and carbonyl (C=O) groups. These functional groups can form hydrogen bonds, acid-base interactions, and complexation reactions with pollutants. Activated carbon can enhance the adsorption of phenolic pollutants through hydrogen bonding.
Heycarbons Activated Carbon Solutions for Refinery Water Pretreatment
Coal Granular Activated Carbon for Demineralized Water Treatment in Refinery Plant
Heycarbons activated carbon is widely used in the pretreatment of demineralized water in oil refineries, providing reliable water quality assurance for critical applications such as steam systems and process water.
Oil refineries have high requirements for the purity and stability of demineralized water, necessitating effective control of organic pollutants and trace impurities.
Heysorbcarb® coal-based activated carbon possesses a well-developed microporous and mesoporous structure, while also containing a certain proportion of macropores. It primarily removes free chlorine, total organic matter (TOC), oil traces, surfactants, and some large-molecule organic compounds from water. Due to its excellent organic matter adsorption capacity, coal-based activated carbon is particularly suitable for the deep removal of TOC, oil, and organic pollutants in demineralized water systems.
