Background
The improvement of the environmental protection standard in China makes the upgrading of the oil quality a necessary choice. C4 catalytic alkylation is an important process for producing clean high octane gasoline blending components (i.e., alkylate). The traditional alkylation technology is mainly divided into a sulfuric acid method and a hydrofluoric acid method, but both the two methods have the problems of serious equipment corrosion, environmental pollution and the like which are difficult to solve, and the wide popularization and application of the alkylation technology are greatly limited. The ionic liquid is a composite salt consisting of alkyl quaternary ammonium cation and composite anion, and the novel alkylation process using the composite ionic liquid as an alkylation reaction catalyst is far superior to the traditional method in terms of product conversion efficiency, process safety and environmental friendliness, and is already widely adopted by newly-built alkylation devices.
The composite ionic liquid catalyst mainly comprises the following components: anhydrous aluminum chloride (AlCl 3), triethylamine hydrochloride (Et 3 NHCl), and transition metal salts (such as Cu2Cl 2). During the alkylation reaction, some acid soluble oil impurities are produced. In order to keep the catalyst in the reaction system to have higher activity and selectivity, when the ionic liquid contains higher acid-soluble oil, fresh ionic liquid needs to be added to keep the catalytic activity, and in the ionic liquid regeneration process, redundant ionic liquid is discharged after concentration and extraction, so that waste ionic liquid is finally formed.
Among the main components of the waste ionic liquid of the chloroaluminate, part of the ionic liquid catalyst with weakened activity; partially salts formed by inactivating the ionic liquid; part of the acid-soluble oil is formed in the alkylation process, and the acid-soluble oil is a dangerous solid waste with high activity, high acidity, high oil content and high salt content, which can cause huge potential safety hazard in direct discharge and storage and must be harmlessly treated.
Chinese patent publication No. CN 105056587A reports a production process for waste ionic liquid treatment. The waste ionic liquid and the high-concentration NaOH solution are fully mixed in the pipeline mixer to react, the alkaline solution containing the metal solid slag is conveyed to a horizontal spiral centrifugal machine for liquid-solid separation, the separated metal solid slag is settled, dehydrated, dried and discharged, and the obtained alkaline clear liquid is mixed with fresh alkali liquor to carry out acid-alkali neutralization reaction. And collecting the dissolved hydrocarbon carried by the ionic liquid into a dirty oil recovery tank. The existing process flow formed according to this patent is: waste ionic liquid is clear, neutralized, precipitated, dehydrated and dried, and each ton of waste ionic liquid generates 1.7 to 1.8 tons of absolute dry solid, and the solid components are as follows: 26% of Al (OH) 3, 8% of Cu (OH) 2, 65% of NaCl and 1% of petroleum. The solid belongs to dangerous waste, the disposal cost reaches 3000-5000 yuan/ton, and the operation cost is very high.
Aiming at the process condition of the waste ionic liquid at present, a novel waste ionic liquid treatment method is urgently needed to be developed so as to achieve the purposes of reducing the amount of dangerous solid waste and reducing the operation cost.

While the digestion reaction in the vacuum kneader 3 is exothermic and hydrochloric acid mist is generated, the generated acid gas is sucked into an acid gas absorber 7 through a suction pump 6 at the top of the vacuum kneader for neutralization and absorption, and an alkaline absorption liquid is contained in the acid gas absorber 7.
The first embodiment is as follows: 100ml of chloroaluminate waste ionic liquid of a petrochemical enterprise is taken and placed in a reaction container, 20ml of water is dropwise added into the reaction container under the condition of uninterrupted stirring, the waste ionic liquid and the water are mixed to carry out moderate digestion reaction, the stirring speed is 600rpm, and the stirring time is 20min until the waste ionic liquid forms granular dry solid matters. The acid gas generated is absorbed by 10% NaOH solution.
