Abstract Due to its excellent heat transfer property, good adaptability to variable loads and operation reliability, large-scale spiral wound heat exchanger (SWHE) has a bright application prospect in the refinery industry of China. With respect to the large-scale hydrocracking unit, both the new heat transfer process and the SWHE design technology are analyzed.
Experiment on adaptability of feed gas flow rate and sea Aug 01, 2019 · This program can predict the variation of the internal temperature and heat transfer coefficient of SWHE along the length of the tube, and capture the natural gas liquefaction point, which provides a theoretical basis for the design and optimization of the spiral wound heat exchanger.
Dec 01, 2019 · The effects of offshore condition on the performance of the SWHE (spiral wound heat exchanger) applied in FLNG attract much attention. Three experimental devices of SWHEs are constructed to quantitatively evaluate how the shell-side pressure drops of FLNG SWHEs are affected by different sloshing angles (39°), periods (630 s) and
IOP Conference Series:Materials Science and Engineering A 2K heat exchanger increases the production rate of superfluid helium by reducing the inlet liquid helium temperature from 4.4 K to 2.2 K or above, recovering sensible heat of evaporated gaseous helium from the helium tanks of the cavities at 2.0 K. Effectiveness of a heat exchanger is the ratio of actual heat transfer to maximum possible heat
Request PDF Influences of tube pitches on heat transfer and pressure drop characteristics of two-phase propane flow boiling in shell side of LNG spiral wound heat exchanger For clarifying the
Process technologies for LNG productionThe heart of a baseload plant is the main heat exchanger (e.g., a spiral-wound heat exchanger, or SWHE). The SWHE consists of pressure vessels containing a number of tubing bundles fabricated with a large number of long, aluminum tubes helically wound around a mandrel or a central core. Numerous tube layers are formed in the radial direction.
