The present invention is related to formulations consisting of block copolymers &#x3b1;,&#x3c9;-di-aryl or alkyl sulfonates of poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide)of bis-ammonium and block copolymers &#x3b1;,&#x3c9;-di-amine of poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide), that are effective in the dewatering and desalting crude whose specific gravities are within the range of 14 to 23&#xb0;API.

Block copolymers, synthesis and application as dehydrating and desalting of heavy crudes

A chemical synthesis process is provided for the functionalization of monodispersed triblock copolymer (POE-POP-POE) with secondary or tertiary amines at a semi-industrial level in glass reactors having a capacity between 1 L and 100 L. The process includes two stages where the first stage uses an alkylsulfonyl or arylsulfonyl chloride to obtain better leaving groups, and the second stage is the nucleophilic substitution with secondary or tertiary amines, to obtain the bifunctionalized triblock copolymers. The main advantage for this process is to reduce the quantity of unitary process done in each stage, the optimization of reaction times, and the stoichiometric relationships.

Scale-up process of bifunctionalized triblock copolymers with secondary and tertiary amines, with application in dewatering and desalting of heavy crude oils

Compositions consisting of block copolymers &#x3b1;,&#x3c9;-di-aryl or alkyl sulfonates of poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide)of bis-ammonium and block copolymers &#x3b1;,&#x3c9;-di-amine of poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide), are provided that are effective in the dewatering and desalting crude oils whose specific gravities are within the range of 14 to 20&#xb0; API. A method of dewatering and desalting heavy crude oil adds a mixture of the copolymer bifunctionalized with an aliphatic or aromatic secondary amine and a copolymer bifunctionalized with an aliphatic or aromatic tertiary amine.

The present invention is related to formulations including one or more block copolymers with low polydispersity and bifunctionalized with amines, and an ionic liquid. A method of demulsifying, dehydrating, and desalting crude oils having API gravity ranging between 8 to 30 admixes the formulation with the crude oil in an amount effective to demulsify, dehydrate and/or desalt the crude oils.

Synergistic formulations of functionalized copolymers and ionic liquids for dehydrated and desalted of medium, heavy and extra heavy crude oils

The present invention relates to demulsifying and dehydrating formulations of heavy crude oil based block copolymers amine bifunctionalized with low polydispersities. These formulations can contain solvents whose boiling point is in the range from 35 to 200&#xb0; C., preferably: dichloromethane, chloroform, toluene, xylenes, turbosine, naphtha or mixtures thereof.

Demulsifying and dehydrating formulations for heavy crude oils based on block copolymers bifunctionalized with amines

The present invention relates to the application of ionic liquids individually or in formulation to dry and desalt crudes oils having API gravities in the range of 8 to 20 (median, heavy and extra-heavy) when applied at concentrations ranging from 500 and up to 5000 ppm. The ionic liquids have a cation consisting of quaternary ammonium, wherein the substituents R, Rand Rare independent radicals represented by alkyl chains including 2 to 8 carbon atoms; and anion selected from the group consisting of ethylsulfate, methylsulfate and chloride.

Dehydrating and desalting median, heavy and extra-heavy oils using ionic liquids and their formulations

A process allows working with viscous petroleum referred to as 'heavy and extra heavy crudes' such as 20 to 6&#xb0; API by adding an appropriate biosurfactant to an aqueous phase containing a biosurfactant active compound. The surfactant can be alkyl glycosides, glycerol esters and alkyl betaines. The result is the formation of a stable crude/water emulsion even with salt present therein.
