For many years mycon uses the self-developed TubeMaster process for cleaning tubes and tube bundle
* Adding a design specification for the 19 tube uniform concentric tube bundle
flow straightener including installation location requirements.
For a refinery in Germany unscheduled shutdowns were reportedly eliminated following the installation of a new tube bundle
in a heat exchanger using hyper-duplex SANDVIK SAF 2707 HD seamless tubes.
Six tenders for the conducting various engineering works to enhance the operations including (a) catalysts unloading & loading with new charges for the reactors, (b) removal of the old ammonia basket and coolers (R - 107) and the erection of the new one, (c) removal of the old reaction tubes and outlet headers for two cells of the primary reformer H - 102 and the erection of the new ones, (d) removal of the old cold & hot tube bundle
and shoulders for the Waste Heat Boiler E - 105 and erection of the new ones, (e) change the tube bundles
for inter coolers and coolers for replacement with new cooler, also (f) check & repair of the T - 101 absorber & T - 102 desorber to remove CO2.
Tube and tube bundle
Tender no: 1305/2012 Description: The scope of work includes supply of tube and tube bundle
Direction of the heat carrier, hydro-flowing around the tube bundle
, depends on the particular situation, and can be very diverse: along, across or at an angle against the tube bundle
For the large-scale sparse tubular heat exchanger, the full-size real tube CFD model is too difficult and expensive to create and the conventional porous media model is not applicable due to the non-uniform flow resistance distribution of the sparse tube bundle
. This paper introduces the semiporous media approach suitable for large-scale sparse tubular heat exchanger airflow and pressure drop predictions.
Low watt-density Incoloy 800 sheath heating elements are arranged to provide even heat inside the tube bundle
. The "Buffer Tank" design solves oil degradation problems associated with hot oil (over 150[degrees]F) reaching the expansion tank without the need for a nitrogen purge system.
Thus it is possible to combine the advantages of the cooking coil with those of the tube bundle
Another cause other than leaky gas cooler is as follows: Exothermic gas passes from the generator through a water cooled tail pipe and into a water cooled tube bundle
. The gas is cooled from an approximate temperature of 1800[degrees]F to around 100[degrees]F through this tail pipe and tube cooling bundle.
The heat exchanger design incorporates a tube bundle
with movable heat transfer elements.
The calcined sand then cascades over a weir plate and drops down into a fluid bed cooler-classifier that employs a water-cooled tube bundle
in the fluid bed media for direct air and indirect water cooling.
