Abstract
The utility model discloses a kind of methanol production system with removing wax function, comprise the methyl alcohol synthetic reactor with charging and discharging mouth, the discharge port of methyl alcohol synthetic reactor is connected with gas-gas heat exchanger, water cooler, methanol separator successively by working line; The feedback outlet of methanol separator returns in methyl alcohol synthetic reactor by recycling pipeline through circulator, gas-gas heat exchanger; In working line, be also provided with wax separator, the opening for feed of this wax separator is connected with the discharge port of methyl alcohol synthetic reactor, and the discharge port of wax separator is connected with the opening for feed of gas-gas heat exchanger.The utility model has the advantage of in working line wax separator is arranged between the gentle gas separating device of methyl alcohol synthetic reactor, the wax of liquefy in methanol production system can be removed clean, liquid wax is avoided to enter the serviceability affecting these equipment in the equipment such as water cooler, air cooler, methanol separator with service pipe, turn avoid the loss of methyl alcohol, ensure that the yield of methyl alcohol.
Description
Technical field
The utility model relates to methanol production, especially relates to a kind of methanol production system with removing wax function.
Background technology
No matter methyl alcohol is low pressure single methanol in process of production, or middle pressure, high-pressure combined methanol all can have the generation of by product wax.In methanol production system, from the methyl alcohol synthetic reactor methanol gas temperature containing other by products such as wax out at 250 DEG C, after gas-gas heat exchanger, temperature can be down to 90 DEG C ~ 110 DEG C, in theory, at this moment the by product of other compositions and methyl alcohol all should be gaseous states, only has wax liquefy, in service pipe, brought into water cooler by gas for avoiding these liquid waxs, air cooler, in the equipment such as methanol separator, affect the working efficiency of these equipment, utility model patent (the patent No.: 201020547117.9 that applicant applied on September 29th, 2010, title " the methanol production system with wax removal function "), propose and increase wax separator on the working line between the gas-gas heat exchanger and water cooler of methanol production system, this technical scheme can to make from gas gas separating device wax out just be separated by wax separator before not entering water cooler, other equipment can not be affected, improve working efficiency, also more environmental protection, this system is in Inner Mongol, Xinjiang, apply in many covers methyl alcohol product installation such as Shanxi, respond well.
But, find from the actual production of the nearly 2 years external methyl alcohol systems of partial capability more than 1,000,000 tons/year introduced, although the working line between gas-gas heat exchanger and water cooler adds wax separator, avoiding wax sticks on these follow-up equipment inwalls, improve heat exchange efficiency and separation efficiency, but the yield of methyl alcohol is but than declining to some extent before.Through technician, the analysis of methanol production equipment, test are found, from methyl alcohol synthetic reactor gas out after gas-gas heat exchanger, in fact the methyl alcohol that should be gaseous state in theory have and occurred liquefied on a small quantity, like this, from gas-gas heat exchanger out containing liquid wax and the methanol gas of other compositions enter again wax separator be separated wax time, the methyl alcohol of part liquefied also can be separated simultaneously, so just cause the loss of methyl alcohol, time maximum, methyl alcohol turnover rate reaches 120kg/h(to produce 1800000 tons of methanol devices per year for benchmark).
Summary of the invention
The purpose of this utility model is to provide a kind of methanol production system with removing wax function that paraffin removal effect can not cause again methyl alcohol to run off that can ensure.
For achieving the above object, the utility model can take following technical proposals:
Methanol production system with removing wax function described in the utility model, comprise the methyl alcohol synthetic reactor with charging and discharging mouth, the discharge port of described methyl alcohol synthetic reactor is connected with gas-gas heat exchanger, water cooler, methanol separator successively by working line; The feedback outlet of described methanol separator returns in methyl alcohol synthetic reactor by recycling pipeline through circulator, gas-gas heat exchanger; In described working line, be also provided with wax separator, the opening for feed of described wax separator is connected with the discharge port of described methyl alcohol synthetic reactor, and the discharge port of described wax separator is connected with the opening for feed of described gas-gas heat exchanger.
Described wax separator is mechanical type gas-liquid separator, centrifugal hyper-gravity gas liquid/gas separator or high-precision membrane separator.
The utility model has the advantage of and can the wax of liquefy in methanol production system be removed totally, liquid wax is avoided to enter the serviceability affecting these equipment in the equipment such as water cooler, air cooler, methanol separator with service pipe, turn avoid the loss of methyl alcohol, ensure that the yield of methyl alcohol.Due to from the methyl alcohol synthetic reactor discharge port methanol gas temperature higher (about 250 DEG C) containing other by products such as wax out, and the flow velocity of gas in pipelines is larger, so, there is no gaseous methanol liquefied completely in working line between the gentle gas separating device of methyl alcohol synthetic reactor, except wax is liquid under this working condition, other products are gaseous state, and wax separator is arranged in the working line between the gentle gas separating device of methyl alcohol synthetic reactor, liquid wax can be separated completely, the loss of methyl alcohol can not be caused again, completely solve the problem that methanol yield is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, methanol production system with removing wax function described in the utility model, comprise the methyl alcohol synthetic reactor with charging and discharging mouth, the discharge port of methyl alcohol synthetic reactor is connected with wax separator, gas-gas heat exchanger, water cooler, methanol separator successively by working line; The feedback outlet of methanol separator returns in methyl alcohol synthetic reactor by recycling pipeline through circulator, gas-gas heat exchanger; Namely in the working line of methyl alcohol synthetic reactor with gas-gas heat exchanger, be in series with wax separator: the opening for feed of this wax separator is connected with the discharge port of methyl alcohol synthetic reactor, the discharge port of wax separator is connected with the opening for feed of gas-gas heat exchanger.
In practical application, wax separator can be static equipment, also can be running device, and its structure can be mechanical type gas-liquid separator, also can be centrifugal hyper-gravity gas liquid/gas separator or high-precision membrane separator.
The utility model uses in China Petrochemical Industry's large-scale methanol production system and the large-scale methanol production system of Datang, runs more than a year continuously, and not only whole system stable performance, paraffin removal are respond well, and methyl alcohol turnover rate is down to zero substantially.
