The methanol synthesis system is characterized in that the methanol reactor is cooled through a heat exchanger and is then connected to the cooler, and the gas outlet of the circulating compressor is heated through the heat exchanger and is then connected to the gas inlet of the methanol reactor. Intake gas in the methanol reactor needs to be heated, the exhausted gas from the methanol reactor needs to be cooled, and heating of the intake gas and cooling of the exhausted gas can be well combined by using the heat exchanger, so that energy consumption can be favourably reduced; and meanwhile, the methanol synthesis system is simple in structure and less in investment and has a remarkable effect.
Description
Technical field
The utility model relates to a kind of methanol synthesizer.
Background technology
The main task of system for methanol synthesis is that building-up reactions generation methyl alcohol takes place in methanol reactor unstripped gas, methanol reactor is worked off one's feeling vent one's spleen and enter methanol separator after the water cooler cooling in the conventional process flow, the liquid phase material of telling enters the methyl alcohol flash drum and carries out flash distillation, flashed vapour removes converter, and thick methyl alcohol is gone out thick methyl alcohol storage tank at the bottom of the methyl alcohol flash drum; Methanol separator top exit gas is participated in reaction after entering the recycle gas compressor pressure-raising as circulation gas once more.But present this system for methanol synthesis exists energy consumption big, and the low deficiency that waits of methyl alcohol synthetic ratio needs to improve.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of energy consumption low system for methanol synthesis at the above-mentioned state of the art.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: system for methanol synthesis, comprise recycle compressor, methanol reactor, methanol separator, water cooler and methyl alcohol flash drum, the reaction outlet of aforementioned methanol reactor connects methanol separator through water cooler, the import of aforementioned methyl alcohol flash drum is connected with the outlet of methanol separator, aforesaid recycle compressor is connected with the inlet mouth of methanol reactor and the hydrogen discharge outlet of methanol separator respectively, it is characterized in that described methanol reactor is connected to water cooler after interchanger cooling, the air outlet of described compressor is connected to the inlet mouth of methanol reactor after aforesaid interchanger heating.
Described interchanger is a shell-and-plate(heat)exchanger.Shell-and-plate(heat)exchanger is the novel heat exchange equipment that integrates plate-type heat exchanger and tube and shell heat exchanger advantage, compare with tube and shell heat exchanger, it has the heat exchange efficiency height, the end has a narrow range of temperature, pressure drop is low, the little and advantages such as saving engineering cost, equipment installation cost and device process cost of floor space.
Described methanol separator is provided with the venting outlet of speeding.Owing to contain rare gas element in the methyl alcohol reaction gas, arrive the balance of methyl alcohol building-up reactions for the accumulation affects of avoiding rare gas element, from working off one's feeling vent one's spleen, extracts methanol separator one off-gas out, with the control inert gas content, this strand off-gas can be sent to converter and do fuel or dehydrogenation recovery, general recover hydrogen is sent into the synthesic gas compressor inlet and is merged with reforming gas, and hydrogen reclaims tail gas and send converter to make fuel again.
The described outlet of speeding to exit is connected with the inlet mouth of PRISM film hydrogen recovery unit, and the air outlet of this PRISM film hydrogen recovery unit is connected with a synthetic compressor, and the inlet mouth of this synthetic compressor is connected with the inlet mouth of recycle compressor.The hydrogen rate of recovery has improved (about 10%), and most of pressure that reclaims hydrogen (more than 81%) can directly enter two sections inlets of synthesic gas compressor more than 3.8MPa, and this strand high pressure reclaims hydrogen can reduce compressor power consumption (approximately 183.38kw/h).Adopt this special film hydrogen recovery technology, make investment cost reduce about 50%.
Compared with prior art, advantage of the present utility model is: intake requirement heating in the methanol reactor, need cooling and give vent to anger, and adopt interchanger well both to be combined, help cutting down the consumption of energy, simultaneously simple in structure, less input, and benefit is obvious.
