20080271880 | Coiled Heat Exchanger Having Different Tube Diameters - A coiled heat exchanger having a plurality of tubes which are wound around a core tube is disclosed. The heat exchanger having a casing which delimits an outer space around the tubes, where the tubes of a first tube group have a first inner diameter and a first outer diameter and the tubes of a second tube group have a second inner diameter and a second outer diameter. The second inner diameter is different from the first inner diameter and/or the second outer diameter is different from the first outer diameter. | 11-06-2008 |
20090301130 | MASS TRANSFER OR HEAT-EXCHANGE COLUMN WITH MASS TRANSFER OF HEAT-EXCHANGE AREAS, SUCH AS TUBE BUNDLES, THAT ARE ARRANGED ABOVE ONE ANOTHER - The invention relates to a mass transfer or heat-exchange column, a tube bundle heat exchanger, with a first mass transfer or heat-exchange area, a first tube bundle ( | 12-10-2009 |

20130068431 | MAIN HEAT EXCHANGER AND A PROCESS FOR COOLING A TUBE SIDE STREAM - A process for cooling a tube side stream in a main heat exchanger is described. The process comprises: a) supplying a first mass flow of a tube side stream to a first zone of individual tubes in the tube bundle; b) supplying a second mass flow of the tube side stream to a second zone of individual tubes in the tube bundle, the second zone being offset from the first zone; c) supplying a refrigerant stream on the shell side for cooling the first and second mass flows; d) removing the evaporated refrigerant stream from the warm end of the main heat exchanger; and, e) adjusting the first mass flow of the tube side stream relative to the second mass flow of the tube side stream to maximise the temperature of the removed evaporated refrigerant stream. | 03-21-2013 |
20130111947 | REBALANCING A MAIN HEAT EXCHANGER IN A PROCESS FOR LIQUEFYING A TUBE SIDE STREAM - A process for liquefying a tube side stream in a main heat exchanger is described. The process comprises the steps of: a) providing a first mass flow to the warm end of a first subset of individual tubes, b) providing a second mass flow to the warm end of a second subset of individual tubes, c) evaporating a refrigerant stream on the shell side; d) measuring an exit temperature of the first mass flow; e) measuring an exit temperature of the second mass flow; and, f) comparing the exit temperature of the first mass flow measured in step d) to the exit temperature of the second mass flow measured in step e), the process characterized in that at least one of the first and second mass flows is adjusted to equalise the exit temperature of the first mass flow with the exit temperature of the second mass flow. | 05-09-2013 |
20150285561 | HEAT EXCHANGER - A helically coiled heat exchanger with a plurality of inlets each connected to at least one assigned tube defining a heating surface of the heat exchanger and having at least one changeover means to switch the inlet between a first operating state and a second operating state. In the first operating state, a stream of a first medium and, in the second operating state, a stream of a second medium is introduced via the inlet into the assigned tube. In the first operating state more heating surface is available to the stream of the first medium and correspondingly less heating surface is available to the stream of the second medium. In the second operating state more heating surface is available to the stream of the second medium and correspondingly less heating surface is available to the stream of the first medium. | 10-08-2015 |
