Regeneration of Spent Acid from Chehical Processes
ثبت نشده
چکیده
The demand for S A R plants is on the rise. this. First and foremost, the requirements for dealing with spent acids in an environmentally safe manner and the shift toward a refinery alkylation process to avoid the possible hazards from hydrogen fluoride. "tolling" or transporting spent acid long distances to independent regeneration plants for recycling is hazardous and may be cost prohibitive. Third, Monsanto Enviro-Chem design technologies and process equipmenr: quality allow these plants to operate virtually uninterrupted f o r two years or more. Several factors are attributed to

Optimization of chemical regeneration procedures of spent activated carbon
The chemical regeneration of granular activated carbon exhausted in a petrochemical wastewater unit was investigated. Gas chromatography and energy-dispersive X-ray spectroscopy demonstrated that spent activated carbon carries large types of organic and inorganic materials. Diverse chemical solvents were adopted in comparison with traditional chemical solvents and regeneration efficiency was in...
متن کاملRegeneration and treatment of sulfidic spent caustic using analytic hierarchy process
Background: Sulfur compounds must be removed from petroleum because they contribute to environmental pollution. A strong alkaline solution such as caustic soda is used to remove these compounds. This spent caustic has high values for chemical oxygen demand (COD) concentration, pH and total sulfur. In this study, the regeneration and treatment methodology of sulfidic spent caustic was inve...

There are no appreciable amounts of nickel resources in Iran; therefore, secondary resources of this element are to be more considered in future. Spent nickel catalysts that are used in various industrial processes are one of them. For example nickel catalyst that is used in hydrogenation of edible oil have large amounts of nickel and they are generally supported on porous materials like silica...
متن کاملKinetic study of the regeneration of spent caustic via the genetic algorithm method
Background: Spent caustic contains noxious components such as sulfide species and also high chemical oxygen demand content (COD). Oxidation of these materials to caustic and sulfate species is mostly the rate-controlling step within catalytic oxidation of spent caustic. Methods: In this study, the kinetics of catalytic oxidation of spent caustic and the regeneration methodology of the sulfidic...
متن کاملChemical Regeneration of Exhausted Granular Activated Carbon Used in Citric Acid Fermentation Solution Decoloration
An improved chemical regeneration of the granular activated carbon (GAC) exhausted by the color (pigments and pollutants) from citric acid fermentation solution (CAF) was investigated. In the experiments, improved means were adopted to advance the traditional chemical regenerating method and the adsorption capacity of the first time renewed GAC is 103% of original GAC. Using oxidan...
