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
  3. Corrosion
  4. Foaming
  5. Scaling

Ceycarb offers low silica activated carbon grades for this application.

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.

 

 

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.

 

Formation of H2S is 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.

 

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.
