CMR (CESTOIL Metal Removal) Technology

CMR Technology Removes Metal from Opportunity Crudes

Cestoil Chemical has developed a chemical treating process that removes calcium and iron from crude oils in the crude unit desalting operation. For example, calcium removal efficiencies as high as 95% have been achieved in units processing crude oils high in calcium naphthenate content, such as Doba crude from Chad. Crude oil iron removal efficiencies greater than 80% have also been achieved in commercial applications of CMR technology. CMR technology also removes amines, ammonia and other alkaline contaminants from crude unit feedstocks.

CMR Technology Benefits

EXCALIBUR technology allows refiners to significantly improve plant profitability by increasing flexibility in selection of crude oil types that can be processed without causing operational or product quality problems. By using CMR technology, refiners can process higher rates of lower cost, opportunity crude oils, while continuing to produce on-specification coke and heavy fuel oils. Refiners have also been able to maintain target rates of reduced crudes to their resid FCCUs while processing high metals crudes.

CMR Technology Overview

CMR technology involves the injection of water soluble complexing agents into the crude unit desalter wash water to increase the solubility of many common contaminants in the aqueous phase. Dissolved contaminants are removed from the desalter with the effluent water drained from the bottom of the vessel.
CMR additives contain corrosion inhibitors that allow their safe use in crude unit desalting equipment. Specially formulated emulsion breaking chemicals are also used to break naphthenate-stabilized emulsions and to maximize crude oil dehydration, thereby minimizing carry over of dissolved contaminants into the desalted crude oil stream. For certain crude oil types, Cestoil Chemical calcium scale inhibitor is applied to prevent deposition of calcium carbonates and sulfates in the desalter effluent water removal system.
