Abstract
A kind of technological process of producing diesel by coal tar, it is mainly characterized by: the technological process of described producing diesel by coal tar includes: head tank (filling coal tar inside described head tank) is set, degumming process (injects concentrated sulphuric acid in glue kettle, stirring, obtain having taken off the coal tar of glue), vaporization process (squeezes into the coal tar having taken off glue the vaporization tower of high temperature, the coal tar having taken off glue is vaporized and obtains coal tar gas), catalytic tower hydrogenation (introduces catalytic tower coal tar gas, inject hydrogen to catalytic tower in proportion and at high temperature carry out catalytic reaction, obtain the gas reacted), desulfurizing tower desulfurization stage, condensing tower condensation phase, in the stages such as oil water separator isolated diesel oil.Technical scheme is relatively easy, invests low, produces effects fast, easily operates, and safety is high, profitable, easily promotes.
Description
Technical field
The present invention relates to a kind of field relevant with oil refining, the field that especially manufacture with diesel oil is closely related.
More specifically, the present invention is the technological process of producing diesel by coal tar.In International Patent Classification (IPC) this
Bright should be divided into the big class of C10.
Background technology
It is known that for the whole world, petroleum-based energy and other combustible gas resource sum are relative to fossil energy
Much less is wanted for source；For China, great disparity, fossil energy 80%, and oil, stone the most relatively
Oil gas, natural gas etc. the most substantially want much less.It addition, the technological process of existing producing diesel by coal tar also has,
But technological process length and more complicated, production efficiency is not high enough, and investment is big, and safety is not high enough, cost
The highest, operate comparatively laborious.
Summary of the invention
It is an object of the invention to: for the deficiency of prior art, it is provided that technological process is short and relatively easy,
Invest relatively low, production efficiency is relatively high, safety is high and cost is than relatively low a kind of producing diesel by coal tar
Technological process.
It is an object of the invention to be achieved through the following technical solutions:
The technological process of described producing diesel by coal tar includes:
(1) head tank is set:
Coal tar is filled inside described head tank；
(2) degumming process:
1) coal tar in head tank is squeezed in glue kettle,
2) in glue kettle, concentrated sulphuric acid is injected,
3) stirring, obtains having taken off the coal tar of glue；
(3) vaporization process:
1) coal tar having taken off glue is squeezed into the vaporization tower of high temperature,
2) in the vaporization tower of high temperature, the coal tar having taken off glue is vaporized and obtains coal tar gas；
(4) catalytic tower hydrogenation:
1) coal tar gas is introduced catalytic tower,
2) inject hydrogen to catalytic tower in proportion and at high temperature carry out catalytic reaction, obtain the gas reacted；
(5) desulfurizing tower desulfurization stage:
1) in desulfurizing tower, desulfurizing agent and activated carbon are loaded in proportion,
2) gas reacted is introduced desulfurizing tower and carry out desulfurization, obtain processed gas；
(6) condensing tower condensation phase:
Processed gas is introduced condensing tower condense, obtain condensed liquid；
(7) at oil water separator isolated diesel oil.
Owing to present invention employs above-mentioned technical scheme, it is evident that the present invention for prior art
Technological process substantially want much shorter, technique is the most relatively easy；Invest the most at a fairly low；Production efficiency also compares
Height, the technological process of the present invention easily operates, and safety is improved, and the cost of production the most also ratio is relatively low,
Be suitable to promote.
Detailed description of the invention
It is provided above technical scheme, in a particular embodiment,
Temperature in the vaporization tower of described high temperature is 320 DEG C.
Hydrogen is 2% with the ratio of coal tar gas.
The described temperature at high temperature carrying out catalytic reaction is 320-380 DEG C.
Described desulfurizing agent and the ratio of activated carbon are 20%: 80%.
Owing to technical scheme is relatively easy, investing low, produce effects fast, easily operate, safety is high, effect
Benefit is good, the most easily promotes.
