Embodiment 1

[0019] A butter inhibitor, composed of the following components by weight percentage: 30% of diethylhydroxylamine, 3% of sodium lignosulfonate, 4% of ammonium dihydrogen phosphate, 0.1% of cellulose airgel microspheres, water quantity.

[0020] The preparation method of the cellulose airgel microspheres is as follows:

[0021] (1) Add 3 parts by weight of cellulose raw material into 80 parts by weight of sodium hydroxide / urea aqueous solution, and stir at -10°C until completely dissolved to obtain a cellulose solution;

[0022] (2) Mix 5 parts by weight of Tween-80 and 200 parts by weight of liquid paraffin evenly, then slowly add the cellulose solution and stir at 40°C for 1 hour, then add 2 parts by weight of epichlorohydrin for crosslinking for 1 hour, and lower the pH of the system Adjust to 4, let stand to separate layers, remove the lower layer of water phase, filter, wash, and freeze-dry to obtain cellulose airgel microspheres.

[0023] The sodium hydroxide / urea aqueo...

Abstract

The invention discloses a butter inhibitor and a production method thereof. The butter inhibitor is composed of the following components by weight percentage: 30-40% of diethylhydroxylamine, 3-8% of sodium lignosulfonate, dihydrogen phosphate Ammonium 4‑5%, cellulose airgel microspheres 0.1‑1%, water balance. The butter inhibitor of the present invention can not only well inhibit the production of butter, but also has a good effect of dispersing and cleaning the already produced butter, ensures the long-term operation stability of the alkali washing tower, and provides convenience for the subsequent treatment of wastewater. High application value.

Description

technical field [0001] The invention relates to the technical field of ethylene production, in particular to a butter inhibitor and a production method thereof. Background technique [0002] In the process of cracking to produce ethylene, the cracked gas contains a large amount of H 2 S and CO 2 and other acid gases. In order to prevent downstream catalyst poisoning and ethylene pollution, ethylene production units are generally equipped with amine washing and alkali washing systems. The pyrolysis gas will produce polymers during the alkali cleaning process, and it is easy to form a yellow viscous state when it contacts with air, which is usually called "butter". The production of a large amount of butter will affect the effect of alkali cleaning and increase the consumption of alkali solution. In severe cases, it will cause unqualified alkali cleaning and affect downstream production. At the same time, a large amount of butter is easy to polymerize and foul to block the...
