In the oil gas industry, activated carbon grades are widely used for different applications. In gas scrubbers purifying of gas treatment liquids such as Benfield solution, MEA etc, in hydrocarbon removing purposes catalytic extraction of mercaptans , in waste water treatment polishing purposes, in vapor recovery processes for recovery of gasoline etc and removal of organic compounds, and iron particles in steam condensates in refineries, are some of main activated carbon applications in oil and gas industry.
Ceycarb offers different grades of special activated carbon products for removing targeted compounds such as VOC , Sulfur oxides , Nitrogen oxides , BTX , phenols, heavy metals, oil and gas mixtures etc, in efficiently and cost – effectively.
Gas scrubbers are used to treat gas treatment liquids such as Benefield solution, DEA, MEA etc. In gas sweetening process, these liquids absorb H2S and CO2 from natural gas reducing corrosion problem and maintaining heating value of the gas.
Ceycarb offers GAC for these gas scrubbers for treating such gas treatment liquids.
Air / Gas purification
For industries such as beverages and certain food processing, water is an essential raw material which is needed to be purified with intensive care. In other uses of water for process applications like boiler feedwater treatment and condensate and contact water treatment applications, water has to be treated. Ceycarb offers different grades including water washed, acid-washed carbon with low silica content, and low iron content.
Boiler Feedwater Treatment
Properly treated water has to be fed to the boilers in order to prevent problems such as: VOC carry over to the steam, Over consumption of boiler water treatment chemicals, Corrosion, Foaming, Scaling
Ceycarb offers low silica-activated carbon grades for this application.
Catalytic extractions of mercaptans and H2S from refinery products are required to remove the sour and foul odours. Ceycarb GAC products are used as carriers for the catalysts for optimal mercaptan to disulfide conversion.
Mercury exists in natural and process gases in elemental and metal salts forms. It is removed from the gases by reacting the mercury with a special impregnation on an activated carbon carrier. The mercury adsorbs to the reactant upon contact as the gas permeates the bed. Elemental mercury degrades, by amalgamation, system piping and equipment. This is especially true of any equipment containing aluminum. Mercury salts are only slightly soluble in water, and deposit in process equipment and enhance corrosion. Residual contamination of fuel, flare, and process off gases has to be closely controlled because of the human health effects.
Ceycarb offers specially manufactured products for mercury removal
At refineries and terminals, economically valuable products such as gasoline vapours, benzene, solvents etc are recovered using activated carbon.
Ceycarb offers range of high working capacity activated carbon products allowing effective adsorption and desorption through numerous cycles. Furthermore, Ceycarb offers consultancy and services in designing economically viable systems for different applications.
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.
Ceycarb’s products, services and consultancy help for cost-effective removal of H2S.
Wastewater in petroleum industry is contaminated with Phenol, Benzene, heavy metals and combination of BTX. BOD level of the water reads as 150 – 250 mg/l while that of COD reads as 300 – 600 mg/l.
Ceycarb offers catalytic products for the efficient removal of hydrocarbons, Phenols, Amoniacal Nitrogen, BTX and heavy metals. Moreover, the products are capable of reducing 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 drainage pipe and Corrosion in concrete sewers are associated with wastewater which contains Sulfur compounds. Ceycarb offers products and services to solve these problems in cost effectively.
Ceycarb GAC products are used in fixed bed filters or in a pseudo-moving bed configuration while PAC products are used in combination with activated sludge process and in coagulation/ flocculation tanks.
Boiler Feedwater Treatment
Properly treated water has to be fed to the boilers in order to prevent problems such as:
1. VOC carry over to the steam
2. Over consumption of boiler water treatment chemicals
Ceycarb offers low silica activated carbon grades for this application.
