Description
- The invention relates to a heat exchanger provided with a series of heat exchange tubes, wherein the one medium flows around the tubes and the other, heat exchanging, medium is passed through the tubes. Heat exchangers of the above, so-called closed, type are widely used in the industry, for example in the oil processing industry for cooling products from hydrocracking installations.
- The present invention relates more in particular to a heat exchanger of the above type which is suitable for the application of gas/liquid mixtures as heat exchanging media.
- When a gas/liquid mixture is applied in the known heat exchangers as heat exchanging medium frequently deterioration of the heat exchange tubes and/or other parts of the heat exchanger occurs. It has been found that such a deterioration is caused by a maldistribution of the gas/liquid mixture over the heat exchange tubes. The problems occurring at maldistribution of the gas/liquid mixture over the heat exchange tubes may originate from the differences in heat exchange properties of gas and liquid. Liquid has a much better heat exchange rate than gas. Therefore, if a high temperature gas/liquid mixture is cooled by passing the mixture through heat exchange tubes surrounded by a low temperature fluid a heat exchange tube receiving much liquid and only a small quantity of gas, will cool down more rapidly and to a greater extent than a heat exchange tube receiving only a small quantity of liquid and relatively much gas. The resulting temperature differences between the heat exchange tubes in the known heat exchangers, may cause excessive stresses. Such stresses may in their turn easily result in damage to the heat exchange tubes and other parts of the heat exchanger.
- The problems occurring at maldistribution of a gas/liquid mixture over the heat exchange tubes of a heat exchanger may also originate from the composition of the gas in the mixture. When a high temperature gas contains dissolved corrosive matter, the corrosive matter may come free upon lowering of the temperature of the gas. This for example occurs upon cooling down gaseous reactor effluents containing corrosive ammonium salts. To absorb such corrosive matter, liquid is supplied to the gas prior to cooling down.
- It has been found that when such a gas mixed with liquid to absorb the corrosive matter in the gas is cooled down by passing the gas through the heat exchange tubes of a known heat exchanger, some of the heat exchange tubes are damaged by corrosion, due to maldistribution of the liquid over the heat exchange tubes. Insufficient liquid has reached part of the tubes to absorb the corrosive matter and/or to wash the corrosive matter from the walls of these tubes.
- From the above it will be clear that gas/liquid mixtures applied as heat exchanging media should be distributed as uniformly as possible over the heat exchange tubes, to avoid deterioration of these tubes.
- The object of the present invention is to improve the known heat exchanger provided with a series of heat exchange tubes in such a manner that when a gas/liquid mixture is supplied for passing through the heat exchange tubes the mixture is uniformly distributed over the heat exchange tubes.
- The heat exchanger according to the invention provided with a series of heat exchange tubes thereto comprises a separator chamber, inlet means for supplying a mixture of liquid and gas into the separator chamber, a series of conduits, each conduit forming a fluid communication between the separator chamber and a heat exchange tube, at least one gutter extending along the series of conduits for collecting liquid in the separator chamber, and means for causing liquid to flow from the gutter(s) to each gas stream passing through a conduit of the series of conduits.
