Problems solved by technology

However, polyether-type demulsifiers need to be used in large doses and act for a long time under the auxiliary action of higher temperature or external electric field to achieve good demulsification effect. The production efficiency is low and the energy consumption is high, which cannot fully meet the requirements of industrial applications. need

Embodiment 1

[0041] Stir and heat choline chloride and 3-phenylpropionic acid with a molar ratio of 1:2 in an oil bath at 90°C at a stirring speed of 150rpm for a heating time of 3h until the reaction mixture becomes a transparent liquid to obtain low-temperature eutectic heavy oil Viscosity reducer, that is, low temperature demulsifier.

Embodiment 2

[0043] Stir and heat choline chloride and urea with a molar ratio of 1:2 in an oil bath at 80°C at a stirring speed of 200rpm for a heating time of 5h until the reaction mixture becomes a transparent liquid to obtain a low-temperature eutectic thick oil viscosity reducer. That is, low temperature demulsifier.

Embodiment 3

Abstract

The invention discloses a low-temperature demulsifier and a preparation method thereof. The low-temperature demulsifier is a eutectic solvent. The hydrogen bond receptor of the eutectic solvent is a compound with a general formula R4NX, and R in the formula is at least one of groups containing C1-C16; and X is halogen. The hydrogen bond donor of the eutectic solvent is at least one of an amide substance, an organic acid substance, a phenol substance and an alcohol substance. Cheap and easily available raw materials are adopted, the eutectic solvent with obvious demulsification and dehydrationeffects on thickened oil is prepared through a one-step heating method, the preparation method is simple and environmentally friendly, and the defects that a traditional demulsifier preparation technology is limited in raw material source, high in price, complex in technological process, serious in three wastes, serious in pollution and the like are overcome. The demulsifier disclosed by the invention is low in use temperature, low in energy consumption and suitable for demulsification and dehydration of various thick oils and super-thick oils, and can meet the requirements of industrial application.

Description

technical field [0001] The application relates to a low-temperature demulsifier and a preparation method thereof, which belong to the field of petrochemical industry. Background technique [0002] When crude oil is extracted, more than 80% of it will contain water to varying degrees. If crude oil is not dehydrated in time, it will increase the load on pumps, pipes and storage tanks, causing corrosion and scaling on metal surfaces, and the oil in the discharged water will also cause environmental pollution. and waste of crude oil. Therefore, it is necessary to demulsify the crude oil to remove water and deoil the sewage. The oil-water separation technologies used in the past, such as sedimentation, adsorption, centrifugation, vacuum separation, and cyclone separation, can separate the non-emulsion water in the oil well, and are generally used in the field of oil purification. Technical means and methods. However, in many cases, the water in the oil does not exist in free fo...
