Petroleum

Because of its unparalleled effectiveness at eliminating contaminants to produce purer refined products, the petroleum industry, which produces fuel, plastics, and even pharmaceutical raw materials, is especially reliant on the use of activated carbon as an adsorbent. CarbUSA's activated carbon products, along with our knowledge and experience in implementing these solutions, are your best choice for ensuring better, purer yields that are good for your company, your consumers, and the environment due to their well-rounded combination of benefits.

Air / Gas Purification

Air / Gas treatment to restrict harmful odorous gases is one of the key requirements in the petroleum industry. In some cases, it is required to treat gases to protect catalysts, downstream equipment, pipes etc. Furthermore, as air emission regulations drive the need for the stringent control of hazardous air pollutants, gases with impurity levels of a few hundred ppm are to be treated cost-effectively. Air/ gas treatment using activated carbon is the cheapest method for this type of treatment and well ahead of any of the other treatment technologies.

Hydrogen Sulfide Removal

The formation of H2S often results in sour crude oil processing. This H2S results in negative implications such as corrosion in pipes and equipment, objectionable odour, hazardous health impacts etc. Hence, the removal of H2S in refineries is very important. CarbUSA’s products, services and consultancy help for cost-effective removal of H2S.

Sweetening

Catalytic extractions of mercaptans and H2S from refinery products are required to remove the sour and foul odours. CarbUSA GAC products are used as carriers for the catalysts for optimal mercaptan to disulfide conversion.

Mercury Removal

The main application of this is exhaust air treatment and solvent recovery by using activated carbon adsorbers. Adsorbers or solvent recovery systems are used. CarbUSA design and install mobile units and provide consulting service where required.

Solvent Recovery

At refineries and terminals, economically valuable products such as gasoline vapours, benzene, solvents etc are recovered using activated carbon. CarbUSA offers a range of high working capacity activated carbon products allowing effective adsorption and desorption through numerous cycles. Furthermore, CarbUSA offers consultancy and services in designing economically viable systems for different applications.

Gas Scrubbers

Gas scrubbers are used to treat gas treatment liquids such as Benefield solution, DEA, MEA etc. In the gas sweetening process, these liquids absorb H2S and CO2 from natural gas reducing the corrosion problem and maintaining the heating value of the gas.
CarbUSA offers GAC for these gas scrubbers for treating such gas treatment liquids.

Removing of Odours Emitted From Wastewater And Sewage Treatment Plants

Wastewater in the petroleum industry is contaminated with Phenol, Benzene, heavy metals, and a combination of BTX. BOD level of the water reads as 150 – 250 mg/l while that of COD reads as 300 – 600 mg/l. CarbUSA offers catalytic products for the efficient removal of hydrocarbons, Phenols, Ammoniacal Nitrogen, BTX and heavy metals. Moreover, the products can reduce BOD and COD levels down to a value very much below the environmental standards. In addition, problems such as Objectionable sulfur taste, “Rotten egg” odour, Corrosion in the drainage pipe and Corrosion in concrete sewers are associated with wastewater which contains Sulfur compounds. CarbUSA offers products and services to solve these problems cost-effectively. Our GAC products are used in fixed bed filters or in a pseudo-moving bed configuration while PAC products are used in combination with the activated sludge process and in coagulation/ flocculation tanks.
