Изобретение относитс к способу паровой каталитической конверсии углеводородов , который используют в химической и нефтехимической промышленности .The invention relates to a method for steam catalytic conversion of hydrocarbons, which is used in the chemical and petrochemical industries.
В насто щее врем при получении исходных газов дл синтеза метанола и аммиака, а также дл производства водорода наиболее широко используют способ паровой или паро-углекислотНОЯ каталитической конверсии углеводородов в трубчатьйх печах под давлением с обогревом реакционных труб гор чими дымовьлми газами l .At present, in the preparation of source gases for the synthesis of methanol and ammonia, as well as for the production of hydrogen, the most widely used method is steam or steam-carbon dioxide catalytic conversion of hydrocarbons in pressure tube furnaces heated by reaction tubes with hot fumes l.
Известен способ паровой каталитической конверсии углеводородов под давлением в трубчатых печах на каталзаторе при 750-950°С, включающий процесс теплообмена, смешени углеводородов с вод ным паром до соотношени пар:газ 4:1, паровую каталитическую конверсию углеводородов в трубчатых печах под действием тепла от сжигани природного газа в горелках с воздухом, сжатом в компрессоре с промежуточным охлаждением воздуха охлаждающей водой и с использованием энергии сжатых дымовых газов в котлах-утилизаторах и в газовой турбине 1.2 .A known method of steam catalytic conversion of hydrocarbons under pressure in tubular furnaces on a catalyst at 750–950 ° C, including the process of heat exchange, mixing hydrocarbons with steam to a steam: gas ratio of 4: 1, steam catalytic conversion of hydrocarbons in tube furnaces under the action of heat from natural gas combustion in burners with air compressed in a compressor with intermediate cooling of air with cooling water and using the energy of compressed flue gases in waste heat boilers and in a gas turbine 1.2.

: Недостатками известного способа вл етс невысока степень конверсии и значительные энергомат-эриальные затраты.: The disadvantages of this method are the low degree of conversion and significant energy and energy costs.
С целью снижени энергозатрат ежи- гание природного газа дл обогрева реакционных труб трубчатой печи осуществл ют Сб сжатым воздухом, содержащим вод ной пар 5-15 об.%.In order to reduce the energy consumption, natural gas run-off for heating the reaction tubes of the tube furnace is carried out by compressed air containing 5–15 vol% water vapor.
Вод ной пар ввод т в сжатый воздух путем частичного испарени воды, нагретой в промежуточных воздухоохладител х компрессора воздуха.Water vapor is introduced into the compressed air by partial evaporation of water heated in the intermediate air coolers of the air compressor.
Применение этого способа позвол ет повысить.эффективность теплообмена в трубчатой печи на 25-30% и, следовательно , .увеличить степень конверсии углеводородов. Полезно использовать энергию, затрачиваемую на сжатие воздух§ в первых ступен х компрессора, компенсировать потери на аэродинамическое сопротивление.The application of this method makes it possible to increase the efficiency of heat exchange in a tube furnace by 25–30% and, consequently, increase the degree of conversion of hydrocarbons. It is useful to use the energy expended in compressing the air in the first stages of the compressor, to compensate for the losses due to aerodynamic drag.
Пример. Природный газ с давлением 15 атм подают в подогреватель,Example. Natural gas with a pressure of 15 atm is fed to the heater,
в котором природный газ подогревают до 400°С продуктами сгорани топлива. Затем осуществл ют очистку природного газа от серы, после чего его см- шивают с потоками вод ного пара иin which natural gas is heated to 400 ° C by the products of combustion of fuel. Then natural gas is cleaned from sulfur, after which it is mixed with water vapor streams and
