Description
В существующих установках дл получени азото-водородной смеси из коксового газа методом глубокого охлаждени промывна колонна работает на довольно низком температурном режиме, что сопр жено с большой энергоемкостью процесса, большой недорекуперацией холода по отход щим потокам и пониженными выходами азота и водорода, содержащихс в коксовом газе.In existing plants, to obtain a nitrogen-hydrogen mixture from coke oven gas by the method of deep cooling, the wash column operates at a rather low temperature conditions, which is coupled with a large process energy intensity, large underrecooling of cold in waste streams and reduced yields of nitrogen and hydrogen contained in the coke oven gas. .
Предлагаемый способ устран ет указанные недостатки путем повышени температурного режима работы промывной колонны, дл чего коксовый газ после дополнительного теплообменника направл ют непосредственно в нижнюю часть промывной колонны, а азотный испаритель используют в качестве дефлегматора, образующего верхнюю часть колонны .The proposed method eliminates these drawbacks by increasing the temperature of the wash column, for which coke oven gas after the additional heat exchanger is sent directly to the bottom of the wash column, and the nitrogen evaporator is used as a reflux condenser that forms the top of the column.
Коксовый газ, предварительно охлажденный до температуры пор дка 165-168°, из дополнительного теплообменника направл ют в нижнюю часть промывной колонны. Здесь газThe coke oven gas, pre-cooled to a temperature in the order of 165-168 °, from an additional heat exchanger is sent to the bottom of the wash column. Here is gas
очищаетс от оставшихс примесей - метана, кислорода и окиси углерода. Очистка газа происходит за счет азотного испарител , расположенного в верхней части колонны и вл ющегос ее дефлегматором. В последнем будет конденсироватьс избыточное количество азота, испарившегос в колонне. Этот сконденсировавшийс азот в виде флегмы будет стекать вниз и промывать поступающие порции газа из нижней части колонны.is purified from residual impurities — methane, oxygen, and carbon monoxide. Gas purification occurs due to the nitrogen evaporator located in the upper part of the column and which is its reflux condenser. The latter will condense the excess amount of nitrogen evaporated in the column. This condensed nitrogen in the form of reflux will flow down and wash the incoming portions of gas from the bottom of the column.
Из азотного испарител обработанна газова смесь направл етс по назначению. Это позволит сократить расход азота и за счет снижени недорекуперации холода повысить выход азота и водорода, содержащихс в исходном коксовом газе, а также уменьшить энергоемкость процесса.From the nitrogen evaporator, the treated gas mixture is directed as intended. This will reduce nitrogen consumption and, by reducing the lack of cold recovery, increase the yield of nitrogen and hydrogen contained in the original coke oven gas, and also reduce the energy intensity of the process.
