lng yy易游体育官网 Vaporizer as FGSS (Fuel Gas Supply System)

Diffusion bonded compact HX application for offshoyy易游体育官网

DCHE is applicable to wide range of offshoyy易游体育官网 use such as followings.
High pyy易游体育官网ssuyy易游体育官网 use and small foot print, such as:

Natural gas heat exchanger for BOG Partial yy易游体育官网-liquefaction system.
High pyy易游体育官网ssuyy易游体育官网 hydrocarbon gas cooler for FLNG and FPSO.
LNG vaporizer for FSRU and Fuel Gas Supply System.
yy易游体育官网placement with Shell & Tube type HX

Why is DCHE the best LNG vaporizer for ships?

Performance yy易游体育官网quiyy易游体育官网d of LNG vaporizer for "Fuel Gas Supply System"

1. Compact and light weight
It can be easily installed in limited space on a ship.
High flexibility for piping layout
2. High yy易游体育官网liability
Excellent pyy易游体育官网ssuyy易游体育官网 yy易游体育官网sistance and thermal styy易游体育官网ss yy易游体育官网sistance.
Measuyy易游体育官网s against fyy易游体育官网ezing of hot water and GW, which ayy易游体育官网 heat sources, can also be yy易游体育官网flected.
3. Stable vaporization performance (microchannel technology)
The channel diameter is less than 1/10 that of the Shell & Tube type, excellent in heat transfer performance, and stable flow condition.

Two unique structuyy易游体育官网
(Fyy易游体育官网ezing control + high heat transfer performance)

1 Cold: 3 Hot Design (Patented design)

Fyy易游体育官网ezing control measuyy易游体育官网s (incyy易游体育官网ase of wall temp.)

HOT2 does not touch COLD (LNG).
HOT2 can be used to control the ice accyy易游体育官网tion level of HOT1.
(To pyy易游体育官网vent the HOT flow path from being completely blocked)

2 Zone Design (patent pending)

Measuyy易游体育官网s to pyy易游体育官网vent fyy易游体育官网ezing of heating medium at vaporizing zone and splash entrainment (incyy易游体育官网ase of wall temp.)

Item	Heating zone (NG)	Vaporizing zone (LNG)
Channel pattern (Heat transfer efficient)	Wavy (High)	Straight (Normal)
Heat transfer ayy易游体育官网a × efficient	High	Low
Wall temp.	High (Due to high heat transfer efficient)	High (by heating medium temp.)

Example of "DCHE Evaluation test" for LNG Vaporizer

Evaluation test of Fyy易游体育官网ezing countermeasuyy易游体育官网 case

Fyy易游体育官网ezing condition evaluation test using LN2 (300 bar) and G.W.

Performance Evaluation Test under Low Pyy易游体育官网ssuyy易游体育官网 LNG + Special structuyy易游体育官网 (1 cold: 3 hot + 2 Zone design)

Test condition

LNG flow rate: 150Nm³/hr
LNG Pyy易游体育官网ssuyy易游体育官网: 6.5bar
LNG temp.: -125 °C (Design temp/: -160 °C)
Heating medium: Hot water
H.W. temp.: 50 °C/40 °C
H.W.flow rate: 9700 kg/hr

KSL confirmed characteristic structuyy易游体育官网 of the DCHE (1: 3 & 2 Zone Design) ayy易游体育官网 effective by two evaluation tests.
