Flow/Boiling Flow Distributor (FDT)
V. Feed/Flashing Feed Distributor (FDT)
5.1 Pipe Type Feed Inlet (FDT-P)
A. Liquid Only Feed Inlet (FDT-P01)
FDT-P01 uses down pipes for better liquid
distribution.
B. Flashing Feed Pipe (FDT-P02)
FDT-P02 provides two-phase flow distribution.
Bottom baffles separate the liquid and vapor.
C. Lateral Pipe Vapor Distributor (FDT-P03)
FDT-P03 introduces a vapor feed at the
bottom of the tower or introduces a vapor to be mixed with the column vapor.
D. Pipe Vapor Distributor with Baffle (FDT-P04)
FDT-P04 allows for proper
distribution through the addition of top baffles to the tube. This directs vapor downwards.
5.2. Streamline Annular Vapor Feed Distributor (FDT-A)
A. Annular Vapor Feed Distributor with Tangential Feed (FDT-A01)
0.1% entrainment
rate. Uniform gas distribution. Low pressure drop. Tangential feed. Also used for flashing feed
distribution.
B. Streamline Annular Vapor Feed Distributor (FDT-A02)
0.1% entrainment rate.
Uniform gas distribution. Low pressure drop. Radial feed. Also used for flashing feed distribution.
5.3. Flashing Feed Gallery (FDT-G) (FDT-G)
A. Multilateral Gallery (FDT-G01)
FDT-G01 comprises a feed device with a
multilateral gallery. A two-phase flow passes through the feed device and pours into gallery, where the
vapor or gas separate from the liquid.
B. Circular Gallery (FDT-G02)
FDT-G02 is composed by a feed device with a circular
gallery. Two-phase flow comes through feed device and pours into gallery where the vapor or gas separate
from liquid.
5.4. Inlet Baffle/ Diffuser (FDT-B)
A. Baffle Type Diffuser (FDT-B01)
FDT-B01 uses a V-baffle to reduce the incoming
flow. With its simple structure, it can effectively separate a two-phase feed.
B. Multi-Baffle Type Diffuser (FDT-B02)
FDT-B02 uses a multi-baffle to reduce the
incoming flow. It can effectively separate a two-phase feed and allows for more uniform distribution.
5.5. Vane Type Vapor Feed Distributor (FDT-V)
Vane Type Vapor Feed Distributor (FDT-V01)
Effectively decreases the momentum of
the inlet feed stream. Prevents bulk liquid and solids from the entering gas flow. Prevents
re-entrainment of previously collected liquid. Also used for flashing feed distribution.
