Problems solved by technology

There are many types of corrosion and scale inhibitors currently in use, but no corrosion and scale inhibitors completely targeted at ethylene compression systems have been reported
However, the use of existing corrosion and scale inhibitors is not highly targeted, and it is difficult to meet the requirements of ethylene compression systems for corrosion and scale inhibition, and the effect of corrosion and scale inhibition is relatively poor.

Embodiment 1

[0015] Embodiment 1: Make 100 grams of the corrosion and scale inhibitor of the present invention.

[0016] Add 68 grams of water and 0.4 grams of sodium hexametaphosphate to the container in turn, control the temperature between 50-90 ° C, stir until the sodium hexametaphosphate is completely dissolved, and after cooling to a suitable temperature, add 3.8 grams of imidazoline, 27.8 gram of ethylenediamine, fully stirred, reacted, cooled to room temperature, and filtered to obtain the product. After testing: the corrosion inhibition rate reaches 98.42%, the scale inhibition rate reaches 96.56%, the effect is remarkable, and it is superior to similar products.

Embodiment 2

[0017] Embodiment 2: making 100 grams of the corrosion and scale inhibitor of the present invention.

[0018] Add 71 grams of water and 0.5 grams of sodium hexametaphosphate to the container in turn, control the temperature between 50-90 ° C, stir until the sodium hexametaphosphate is completely dissolved, and after cooling to a suitable temperature, add 2.9 grams of imidazoline, 25.6 gram of ethylenediamine, fully stirred, reacted, cooled to room temperature, and filtered to obtain the product. After testing: the corrosion inhibition rate reaches 99.04%, the scale inhibition rate reaches 97.82%, the effect is remarkable, and it is superior to similar products.

[0019] The using method of corrosion and scale inhibition of the present invention is: 1, set up reagent tank: set up volume > 3M 3 1. A reagent tank for containing the corrosion and scale inhibitor, which communicates with the reagent injection port through a pipeline, and injects the reagent with a reagent pump. T...

Abstract

The invention discloses a corrosion inhibition and scale inhabitation agent specially used for an ethylene compression system, belonging to the chemical engineering technical field. The compositions by weight percentage of the corrosion inhibition and scale inhabitation agent are: 20 to 35 percent of ethylenediamine, 1 to 5 percent of imidazoline, 0.1 to 1 percent of sodium hexametahposphate and 60 to 75 percent of water. The corrosion inhibition and scale inhabitation agent is a composite organic product and is a special corrosion inhibition and scale inhabitation agent developed for the ethylene compression system; the corrosion inhibition and scale inhabitation effect is good and can completely meet the requirements of the ethylene compression system; and the corrosion inhibition and scale inhabitation agent replenishes the blank of corrosion inhibition and scale inhabitation agent of the type. Simultaneously, the corrosion inhibition and scale inhabitation agent is applied to an oil and gas well and a pipeline in which sulfurated hydrogen, carbon dioxides and water coexist, which can play a good part in corrosion inhibition and scale inhabitation.

Description

1. Technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a corrosion and scale inhibitor specially used for ethylene compression systems. 2. Background technology [0002] At present, the ethylene compression system is five-stage compression, with cooling water between the stages, and the outlet gas of the fifth stage is cooled by cooling water, and then cooled by low-temperature materials and propylene refrigerant. The interstage condensate is divided into two parts: heavy component and light component. The heavy component is passed through the gasoline stripper to obtain pyrolysis gasoline fraction; the light component is passed through the condensate stripper to obtain C3 and light hydrocarbon condensate above C3. Since the outlet of the first three stages of the compressor is equipped with an acid gas removal system (alkali washing or alcohol amine liquid-alkali washing) to remove CO in the cracked gas 2 a...
