Embodiment 1

[0043] The homogenizer for DRA monomer includes: 1200 g of octanol, 50 g of water, 200 g of butanol, 240 g of ethylene glycol, and 100 g of diethylene glycol butyl ether.

[0044] Preparation of DRA monomer suspension: use liquid nitrogen to cool 3600g of polyalphaolefin to the glass transition temperature before crushing, add 1075g of polypropylene wax powder and 1075g of polyethylene wax powder as encapsulating agent, and encapsulating agent is wrapped in the pulverized For the final polyα-olefin, 1150 g of homogenizer for DRA monomer was added to the polyα-olefin coated with wrapping agent, and put into a homogenizer for homogenization to obtain DRA monomer suspension.

Abstract

A DRA monomer is an intermediate in a production process of a drag reducing agent (DRA). The invention discloses a suspension DRA monomer homogenizing agent including the following components in parts by weight: 50-70 parts of octanol, 2-5 parts of water, 10 parts of butanol, and 10-15 parts of ethylene glycol; a DRA monomer suspension prepared by the DRA monomer homogenizing agent includes the following components in parts by weight: 35-40 parts of a DRA monomer powder, 20-22 parts of a wrapping agent, and 10-12 parts of the DRA monomer homogenizing agent. The DRA monomer homogenizing agent can effectively reduce generation of the agglomeration phenomenon in the DRA suspension, so as to ensure that the DRA monomer suspension has good fluidity and drag reducing effects.

Description

technical field [0001] The invention relates to the technical field of post-treatment of DRA monomers, more specifically, it relates to a homogenizer for DRA monomers and the DRA monomer suspension prepared therefrom. Background technique [0002] The chemical agent used to reduce fluid flow resistance is called drag reducing agent (DRA for short), and the intermediate in the production process of drag reducing agent is usually DRA monomer. Drag reducers are widely used in the transportation of crude oil and refined oil pipelines. Adding a small amount into turbulent oil products can convert turbulent flow into laminar flow, greatly reducing the frictional resistance of the pipeline system, thereby expanding the flow of oil pipelines and reducing the energy consumption of delivery pumps , Improve the safety factor of oil pipeline operation. The more common drag reducer polymer (DRA monomer) is a polymer of long carbon chain α-olefin synthetic rubber (C6-C18), styrene or vin...
