Abstract
The invention provides a method for treating condensate of a flare gas accident liquid separation tank.The condensate of the accident liquid separation tank is conveyed into a polyhydric alcohol workshop through a condensate pump to be mixed with a 2-ethyl hexanol storage tank, and organic materials are recycled to serve as organic fuel to be sold.Economic benefits are improved, stable operation of a sewage station is guaranteed, and odors caused by organic matter are also eliminated.
Description
Technical field
The invention belongs to chemical field, the processing method being specifically related in a kind of octyl alconyl project torch gas accident separatory tank lime set.
Background technology
Butanol and capryl alcohol owing to can produce by the method for oxo process in same set of device, therefore custom is called octyl alconyl.Butanol and capryl alcohol are water white transparency, inflammable oily liquids, have special odor, can form azeotropic mixture with water and multiple compounds, all have moderate toxicity.Octyl alconyl is the important source material of synthesis fine chemical product, mainly for the production of plasticizer, solvent, dehydrant, defoamer, dispersant, flotation agent, petroleum additive and synthetic perfume etc..
Butyl octanol unit newly-built in current world wide all adopts modified rhodium series catalysts low pressure oxo synthesis, with propylene, synthesis gas and hydrogen for raw material, mixing butyraldehyde is generated under catalyst action, isolate catalyst to recycle, isolate the hydrogenated generation n-butyl alcohol of just/isobutylaldehyde and isobutanol, separate through rectification and obtain n-butyl alcohol and isobutanol product；Hutanal condensation dehydration under the catalytic action of sodium hydroxide generates octenal, and octenal hydrogenation produces thick capryl alcohol, obtains product capryl alcohol through rectification.
The waste gas of butyl octanol unit discharge refers mainly to technology waste gas, its source is 1. oxo process periodic off-gases, it is mainly composed of hydrogen, methane, propylene, propane etc., it it is the discharge in order to noble gas and propane in anti-locking system accumulate and carries out, propylene therein, propane and butyraldehyde can reclaim, and the tail gas after recovery send torch burning again；2. octenal, butyraldehyde are hydrogenated with periodic off-gases, are mainly composed of hydrogen and methane etc., are the discharges carried out to prevent the accumulation of system. Inert gas, and hydrogen therein can reclaim, and tail gas send torch burning again；3. torch gas, the pressure regulation gas of Shi Ge workshop section generation, pressure release gas, it is mainly composed of hydrogen, methane, nitrogen and hydro carbons, all send torch burning；4. low pressure drain tail gas during product loading, contains the Organic substance of the contaminated environment such as butyraldehyde, butanol, capryl alcohol in the tail gas of discharge.
Flare discharge gas is delivered to flare system battery limit (BL) by DN500 torch gas house steward.Accident water sealed cans are entered after the droplet more than 300～600 μm isolated by accident separatory tank.Discharge gas is broken through and is entered torch cylinder after water sealed tank, burns through octyl alconyl flare tip after.The lime set that accident separatory tank separates mainly contains the organic materials such as butanol, capryl alcohol, butyraldehyde, octenal, is pumped to sewage plant neutralization pond by lime set and carries out sewage disposal.
Summary of the invention
It is an object of the invention to provide the processing method of a kind of torch gas accident separatory tank lime set, accident separatory tank lime set is pumped into polyhydric alcohol workshop mixing octyl alconyl storage tank by lime set, reclaim organic materials and sell as outside organic-fuel.
Former flow process accident separatory tank relief liquor is delivered to sewage plant will result directly in sewage plant discharge water COD exceed standard, affect the stable operation of sewage plant；The organic materials such as the butanol that simultaneously contains in sewage, capryl alcohol, butyraldehyde, octenal all have abnormal flavour, sewage plant neutralization pond to be outdoor ponds, and abnormal flavour flies away, and affects environment；After transformation, accident separatory tank lime set is sent directly into outside mixing octyl alconyl storage tank and sells, both added economic benefit and in turn ensure that the stable operation of sewage plant, also eliminated the abnormal flavour that Organic substance brings simultaneously.
Accompanying drawing explanation
The former torch gas lime set discharge method of Fig. 1
1 is accident separatory tank, and 2 is lime set pump, and 3 is neutralization pond.
Fig. 2 torch gas lime set discharge method provided by the invention
1 is accident separatory tank, and 2 is lime set pump, and 3 is mixing octyl alconyl storage tank.
Detailed description of the invention
Embodiment 1
Certain chemical plant octyl alconyl project domestic, originally because accident separatory tank lime set is discharged to sewage plant, causes that sewage plant discharge water COD exceeds standard, and around has the abnormal flavour of the organic materials such as butanol, capryl alcohol, butyraldehyde, octenal to fill the air.Adopt method provided by the invention, accident separatory tank lime set is pumped into polyhydric alcohol workshop mixing octyl alconyl storage tank by lime set, reclaim organic materials to sell as outside organic-fuel, sewage plant discharge water COD is down to normal range, abnormal flavour in air is significantly reduced, and the annual organic products that reclaims rises in value 1,000,000 yuan more simultaneously.
Embodiment 2
Certain chemical plant octyl alconyl project domestic, originally because accident separatory tank lime set is discharged to sewage plant, causes that sewage plant discharge water COD exceeds standard, and around has the abnormal flavour of the organic materials such as butanol, capryl alcohol, butyraldehyde, octenal to fill the air.Adopt method provided by the invention, accident separatory tank lime set is pumped into polyhydric alcohol workshop mixing octyl alconyl storage tank by lime set, reclaim organic materials to sell as outside organic-fuel, sewage plant discharge water COD declines 30%, Organic substance odor eliminating in air, the annual organic productss that reclaim rise in value 1,500,000 yuan more.
