Problems solved by technology

However, this equipment is mainly used for the treatment of oily sewage, that is, the treatment of oil removal in water, and this equipment is not applicable in the alkylation unit
[0009] Therefore, due to the above-mentioned problems in the prior art, the proprietary equipment for the efficient separation of oil and water (oleic acid) in the alkylation unit has not been solved so far, and it is far from meeting the expectations of industrialization of petrochemical production.

Embodiment 1

[0030] In a 200,000-ton / year alkylation project in Shandong Province, the high-efficiency coalescing separation equipment of the present invention is used to separate the extracted refrigerant-propane and water.

[0031] Its specific operation process and effect are described as follows:

[0032] 1. Operating conditions of propane dehydration equipment

[0033] The main components are: volume flow, 95% propane, 5% water; the processing capacity is propane 1063kg / h, water 72kg / h, operating temperature 52 ℃, operating pressure 1.75MPa. as attached figure 2 As shown in the figure, since the content of the oil phase is much larger than that of the water phase, it belongs to the dehydration process in the oil, so the oil collecting chamber at the top of the casing is changed to a water bag at the bottom of the casing, and the water phase outlet is set on the water bag.

[0034] 2. Implementation process

[0035] The mixture of propane and water enters the high-efficiency coales...

Embodiment 2

[0041] In a 160,000-ton / year industrial isooctane project in Zhejiang Province, the high-efficiency coalescence separation equipment of the present invention is used in the acid settling tank to separate the oil phase-mixed hydrocarbons and concentrated sulfuric acid.

Abstract

The invention discloses efficient coalescence-separation equipment for an alkylating device, and belongs to the field of oil-water separation of petrochemical industry. The efficient coalescence-separation equipment comprises a housing and an internal part; a mixed liquid inlet part, a water (acid) phase outlet part, and an oil phase outlet part are formed in the housing; a liquid distributor is arranged at the mixed liquid inlet part; an oil collecting chamber above which an oil phase outlet is formed is arranged at the oil phase outlet part; a rectifying and uniform distributing device, a coarse graining coalescence section, a modified corrugated and reinforced separation section and a nanofiber deep separation section are arranged in the housing along the direction the mixed liquid flows; a position gauge is also arranged in the housing. According to the efficient coalescence-separation equipment for the alkylating device, the shallow pool theory and coarse graining technology are integrated, so that high oil-water (-acid) separation efficiency can be realized; compared with the existing single filler oil-water separation equipment, the efficient coalescence-separation equipment, disclosed by the invention, has obvious characteristics of being high in separation efficiency, high in processing capability, high in operation flexibility, small in floor area, small in one-time investment for equipment, etc.

Description

technical field [0001] The patent of the present invention relates to the technical field of petrochemical industry, especially to the high-efficiency coalescence and separation equipment of oil-water (oleic acid) in the alkylation unit. Background technique [0002] For a long time, the quality of my country's oil products has lagged behind, and the content of sulfur, aromatics and olefins in them is high, which increases the pollution level of vehicle exhaust emissions and becomes one of the driving forces for the frequent occurrence of haze weather. With the increasingly stringent environmental regulations and the continuous upgrading of gasoline quality indicators, the demand for clean fuels in domestic and foreign markets continues to increase. [0003] The alkylation unit uses isobutane and low molecular olefins (usually C3-C5 olefins, currently mainly n-butene) in liquefied gas as raw materials, and reacts under the action of strong acid catalyst (sulfuric acid) to fo...
