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.
