Description
Technical field
A kind of Deep Cooling Method petroleum vapor recovery and processing combiner are the utility model is related to, belongs to chemical industry environmental protection and deep cooling field.
Background technology
The Air Pollutant Emission limit value of the petroleum refining industry pollutant emission performed since 1 day July in 2017 is non-
Methane total hydrocarbon is 120mg/m3, removal rate >=95% (GB31570-2015, abbreviation new standard), than pervious standard GB2095-
2007 gas concentrations≤25g/m3Stringent many, differs more than 200 times.It is not small to perform new standard difficulty.Only have in the world at present
It is horizontal that Germany can reach this.
Before and after Beijing Olympic Games, the technology that China is introduced from the U.S., Japan, European Union also can only achieve former standard.We adopt
It is refrigerant to discharge gas itself, it is compressed to expand deep cooling processed, the Deep Cooling Method petroleum vapor recovery developed and processing combiner, not only
Petroleum vapor recovery can be made to bring up to 99%, and discharge gas can be made to reach the requirement of new standard, combiner is an energy-saving ring
The skid mounted equipment of guarantor's type.
The content of the invention
The main feature of the utility model is that：Space division Refrigeration Technique, backheat technology, the heat exchanger and height of superior structural
Imitate separator.Make air compression-expansion refrigeration and chemical industry enfleurage, backheat organic connections, interaction, this will be substantially improved
The operating mode of air compression-expansion refrigeration, substantially reduces refrigeration power consumption.Deep cooling height is mentioned into general chemical industry enfleurage at the same time so that
Air compression-expansion refrigeration only needs offer to overcome the cold damage of system and condenses a small amount of cold of a small amount of (1%) oil gas necessary complement.
The utility model can thus be reached and provide a kind of deep cooling for the high-efficient energy-saving environment friendly that can overcome prior art shortcoming to society
Method petroleum vapor recovery and the purpose for handling combiner.
A kind of Deep Cooling Method petroleum vapor recovery and processing combiner, it is characterised in that the combiner includes：It is compressor (a), air-cooled
Device (b), static mixer (c), return cooler (d), condenser (e), expanding machine (f), separator (g, h, i), circulating pump (j) and its
Specific connecting pipeline to each other.
Recycling oil gas is connected by pipeline with the back pressure machine entrance of expanding machine, and compressor (a) is entered after primary compression and is compressed,
Static mixer (c) entrance is met at circulating pump (j) export pipeline after air cooler (b) cooling after compression, by separator
(g) liquid phase oil is obtained.Gas phase respectively enters back cooler (d), condenser (e) is inflated the low temperature exhaust gas cooling after machine expansion (f)
And condensation, subsequently into separator (h), liquid phase enters circulating pump (j) as circulation fluid, and gas phase enters expanding machine (f) expanding end,
Enter separator (i) after expansion, liquid phase enters circulating pump (j) as circulation fluid, and gas phase is successively by condenser (e), time cooler
(d) emptied after recycling cold.
Brief description of the drawings
Fig. 1 is process flow chart.
Embodiment
Embodiment 1, further illustrates with reference to attached drawing：
Oil-containing ＜ 25g/m3Petrol gas recycling.Oil gas is compressed to 0.2MPa by expanding machine (f) back pressure machine again to lead to
Overcompression machine (a) is compressed to 0.6MPa, and enters static mixer (c) after air cooler (b) cooling, and from separator (h)
Mixed with the cold oil of separator (i), mixed gas-liquid mixture enters separator (g), the oil gas separated in separator (g)
It is cooled to -70 DEG C or so in advance into cooler (d) is returned, the oil gas after precooling enters condenser (e) condensation to less than -100 DEG C, through separation
The expanding end of gas phase into expanding machine (f) is expanded to 0.15MPa after device (h) separation, is cooled to -160 DEG C or so, condensed device
(e) and after returning cooler (d) recycling cold it is vented.The liquid phase of separator (h) and separator (i) is entered static by circulating pump (j)
Mixer (c), the liquid phase of separator (g) is oil recovery.
Claims (1)
1. a kind of Deep Cooling Method petroleum vapor recovery and processing combiner, it is characterised in that the combiner includes：Compressor (a), air cooler
(b), static mixer (c), return cooler (d), condenser (e), expanding machine (f), separator (g, h, i), circulating pump (j) and its that
Connecting pipeline around here, recycling oil gas are connected by pipeline with the back pressure machine entrance of expanding machine, and compressor is entered after primary compression
(a) compress, meet at static mixer (c) entrance with circulating pump (j) export pipeline after air cooler (b) cooling after compression, pass through
Cross separator (g) and obtain liquid phase oil, gas phase respectively enters back cooler (d), condenser (e) is inflated the low temperature after machine expansion (f)
Tail gas cools down and condensation, enters circulating pump (j) as circulation fluid subsequently into separator (h), liquid phase, gas phase enters expanding machine
(f) expanding end, enters separator (i) after expansion, liquid phase enters circulating pump (j) as circulation fluid, and gas phase passes through condenser successively
(e), emptied after returning cooler (d) recycling cold.
