Abstract

A process for treating the oil-contained sludge includes thermal dewatering 80-90 % at 120-140 deg.C, adding catalyst and carbonizing reaction at 400-500 deg.C for catalytically cracking the oil while condensating the colloidal asphalt to become coke to be adsorbed by dried mud.

Description

Oil sludge carbonization treatment method

Technical field:

The present invention relates to the processing of the solid waste used on the well site, a kind of oil field, particularly a kind of oil sludge carbonization treatment method.

Background technology:

Attach great importance to biological treatment and the disposal technology and the high-temperature process Study on Technology of oily sludge both at home and abroad.Domestic still do not have a very ripe greasy filth comprehensive utilization technique.The present equal imperfection of technology that adopts; Burning method is to build special burning facility to cooperate diesel oil that oil sludge and sand is burned, and this method one is the equipment investment height; The 2nd, the operating cost height; The 3rd, cause energy waste, though processing is more thorough, the practical application difficulty is very big.Partition method is to adopt oil and sand separation in physics or the chemical method oil sludge and sand to come out, this method can be recycled the oil in the oil sludge and sand, but cost is higher, and the silt particle that separates can contain certain petroleum substance, directly enter in the environment and also can cause environmental pollution, so the silt particle that this method is separated still needs to adopt burning method, deposits method or the method for burying is handled.Biological degradation method is meant and utilizes microorganism to contain the oils substance decomposition in the oil sludge and sand, and cost is higher, and technology is very ripe, and contained oily substance can not effectively utilize.

Technical scheme

The object of the present invention is to provide a kind of oil sludge carbonization treatment method, it can effectively reclaim the mineral oil in the greasy filth, and mineral oil content is controlled at below 0.3% after the greasy filth carbonization, and certain calorific value is arranged, and can be used as fuel.

The object of the present invention is achieved like this, at first greasy filth is sent into preprocessor through promoting hopper, after the dehydrothermal, the part oil product enters the product oil storage tank, all moisture and part lighter hydrocarbons, oil gas are separated out and are entered condenser, and condensation Hou Shui, oil and lighter hydrocarbons gas enter water pot, oil gas collection device respectively.

Secondly, remaining greasy filth enters in the reactor again in the preprocessor, heating, and the residue lighter hydrocarbons in the petroleum-type distill out, and under the catalysis of catalyst, colloid and asphalitine generation cracking produce lighter hydrocarbons gas and light oil, remaining petroleum-type carbonization coke.Lighter hydrocarbons gas and light oil are separated out and are entered condenser, enter the oil gas collection device after the condensation.

Once more, in the oil gas collection device, oil product enters the product oil storage tank, and lighter hydrocarbons gas enters poisonous and harmful, corrosive gas in the scrubber tower eccysis lighter hydrocarbons gas.

At last, coke in the reactor and the lighter hydrocarbons gas after washing and coal are sent into to add and are made fuel in the boiler to preprocessor and reactor heating.The environmental protection silt particle enters the outside.

The present invention is because with the oily sludge thermal dehydration, through the pretreatment reaction device, in 120-140 ℃ of temperature range, deviate from the water of 80-90%, greasy filth after the dehydration enters carbonization reactor, in reactor, add a certain amount of catalyst simultaneously, under 400-500 ℃ reaction condition, carry out catalytic reaction, by the pyroreaction in the presence of catalyst, mainly make the oil content of earth absorption carry out catalytic cracking reaction, colloidal bitumen part condensation in the greasy filth simultaneously becomes coke, and be adsorbed in the dry ground, reach the standard that the national requirements for environmental protection discharging is buried fully through reacted dry ground.Program of the present invention is simple, and effect is remarkable, is the minimizing of oily sludge, the good approach of innoxious, resource, is well suited for field popularization application.

Description of drawings

As figure is flow chart of the present invention.

The present invention is further described below in conjunction with accompanying drawing.

Embodiment

As shown in the figure,

This technology path is: the oily sludge thermal dehydration, through the pretreatment reaction device, in 120-140 ℃ of temperature range, deviate from the water of 80-90%, greasy filth after the dehydration enters carbonization reactor, in reactor, add a certain amount of catalyst simultaneously, under 400-500 ℃ reaction condition, carry out catalytic reaction, by the pyroreaction in the presence of catalyst, mainly make the oil content of earth absorption carry out catalytic cracking reaction, colloidal bitumen part condensation in the greasy filth simultaneously becomes coke, and be adsorbed in the dry ground, reach the standard that the national requirements for environmental protection discharging is buried fully through reacted dry ground.

The heavy oil that contains in the greasy filth has more gum asphalt, under the effect of catalyst, can cracking in lower temperature range, and it is lower to produce burnt rate simultaneously, and dry gas is also less, and oil recovery rate is higher.This technology can be reacted the oil content that contains in the earth through catalytic thermal cracking method become oil content and part of coke.Avoided other method (as, separated from solvent and centrifugal separation) oil in the earth can not be separated fully, do not satisfy the national standard that earth discharging is buried.

Developed greasy filth carbonization treatment disposal technology, can effectively reclaim the mineral oil in the greasy filth, mineral oil content is controlled at below 0.3% after the greasy filth carbonization, and certain calorific value is arranged, and can be used as fuel.Heating boiler: for preprocessor and reactor provide thermal source, raw material is coal, lighter hydrocarbons gas, the coke after greasy filth is handled.

At first greasy filth is sent into preprocessor through promoting hopper, after the dehydrothermal, the part oil product enters the product oil storage tank, and all moisture and part lighter hydrocarbons, oil gas are separated out and entered condenser, and condensation Hou Shui, oil and lighter hydrocarbons gas enter water pot, oil gas collection device respectively.

Secondly, remaining greasy filth enters in the reactor again in the preprocessor, heating, and the residue lighter hydrocarbons in the petroleum-type distill out, and under the catalysis of catalyst, colloid and asphalitine generation cracking produce lighter hydrocarbons gas and light oil, remaining petroleum-type carbonization coke.Lighter hydrocarbons gas and light oil are separated out and are entered condenser, enter the oil gas collection device after the condensation.

Once more, in the oil gas collection device, oil product enters the product oil storage tank, and lighter hydrocarbons gas enters poisonous and harmful, corrosive gas in the scrubber tower eccysis lighter hydrocarbons gas.

At last, coke in the reactor and the lighter hydrocarbons gas after washing and coal are sent into to add and are made fuel in the boiler to preprocessor and reactor heating.The environmental protection silt particle enters the outside.
