The document discusses pneumatic conveying systems which use pressurized air to transport materials through pipes. It describes the basic components which include pressure blowers, rotary valves, piping, filters and cyclones. There are three main types of systems - suction, pressure, and combination systems. Materials can be conveyed in either dilute phase with high air velocity, or dense phase with higher pressure and lower velocity. Key factors in determining the system type include operating pressure, air velocity and material properties.

One of the most popular methods of moving solids in the chemical industry is pneumatic conveying. Pneumatic conveying refers to the moving of solids suspended in or forced by a gas stream through horizontal and/or vertical pipes. Pneumatic conveying can be used for particles ranging from fine powders to pellets and bulk densities of 16 to 3200 kg/m3 (1 to 200 lb/ft3).
Steam distribution system, utilization and designAzmir Latif Beg
n any steam plant or any process plant effectiveness of steam distribution system is dependent upon the project specific conditions like location and layout of the process plant and its steam consuming equipment like heat exchangers, decorators etc. Steam distribution circuit is one of the major link between the steam production point and the point of end use i.e. process plant. Primary steam generating source are co-generation plant and Steam generators. However it not the source of steam generation but the effective and efficient steam distribution system that decides right quality (pressure and temperature) and quantity of steam to reach to the process through it. Thus designing of steam distribution is to be given due importance along with installation and subsequently maintenance during operation.

Choose the correct pneumatic conveyors for efficient transferring of materialsTrimech India
There are several other properties to consider when opting for Pneumatic Conveyors for efficiently conducting application work depending upon different factors.
Material handling equipments : conveyors and elevators ajaz malla
Material handling is the movement, protection, storage and control of materials and products throughout manufacturing, warehousing, distribution, consumption and disposal. As a process, material handling incorporates a wide range of manual, semi-automated and automated equipment and systems that support logistics and make the supply chain work.
Dilute phase conveying system or Lean phase conveying system is described as the process of (pressure) pushing or (vacuum) pulling particles suspended in air from one location to another. Basically Dilute Phase conveying systems are a mode of transporting powders generally through a positive displacement blower, side channel blowers or vacuum pumps. It is a simple system used for various powders that doesn’t have any specific quality requirements for degradation or loss of material properties.
Pneumatic conveying is a highly efficient method of material transport and is used in a variety of industries to ensure the safe transfer of resources and products. If you have any questions pertaining to pneumatic conveying system design.

The Conveying system where the Solids to air ratio (μ=kgmaterial/kgair)is high ( < 15) is normally considered a dense phase mode of conveying. In this case, the velocity is less than the saltation velocity. Due to the above reason high conveying pressure with low air velocity is possible and suitable powders where the handling needs are for low breakage, fragile & abrasives, this system becomes an ideal solution.
Dilute phase, on the other hand, is Characterized by a uniform distribution of the particles along all sections of the conveying line, with a suspension flow regime, i.e. transport velocity higher than the saltation velocity (minimum velocity to keep all material in suspension).
While selecting a system one should consider some parameters like the length of the conveying system, conveying capacity, the velocity of the air and its conveying air volume, and conveying pressure.
The Above system configuration plays a very crucial role in choosing the Dense and Dilute phases. The data below should be considered as stated in slide no.6
Material properties are the most important guidance as the type of conveying system depends on the material properties like particle size, density, fragile, toughness, abrasive, hardness, strength, fatigue etc. For the Dilute Phase pneumatic system materials that are free-flowing and non-abrasive are used.
And for Dense Phase Pneumatic System the materials best suited that are abrasive, heavier, fragile, and have the tendency to degrade.
Dilute Phase Pneumatic System consumes less energy.
The Question arises which to choose among them- the answer depends on three things: material properties, conveying distance, and conveying capacity.
For Long-distance conveying and high-capacity material flow Dense phase is preferred
For Short-distance and low-capacity powder transfer, dilute phase are preferred.
The Above points would be easy to distinguish whether to use dilute or dense phase and which one will be feasible for you
Dense phase may not be as energy efficient as the Lean or Dilute phase as the compressor is used to deliver air at 6 barg.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

2. Introduction
What is Pneumatic Conveying(PC):
•Every pneumatic system, makes use of pipes or ducts called transportation lines
that carry mixture of materials and a stream of air . These materials can be
transported conveniently to various destinations by means of a stream of high
velocity air through pipe lines. Products are moved through various tubes via air
pressure, allowing for extra vertical versatility.
•Pneumatic conveying is routinely used to move solids of all sizes within process plants.
On account of the compressibility of the conveying gas, the pneumatic conveying of
solids is quite different from the pumping of liquids or slurries The selection of many of
the components that comprise a conveying system such as rotary valves, feed
chutes, conveying pipe, and air movers is examined, especially as it relates to reliable
operation of a conveying system.
3. •Energy is also required to move material through a pneumatic conveying system, but in th
Introduction
case the energy is supplied by pressure differential (in pounds per square
inch) and airflow(in cubic feet per minute).
•In a pneumatic conveying system, the air pressure in the conveying line is changed by the
system’s air mover, which generates pressure or vacuum. Where the air mover is located in
the system determines whether it generates one or the other. When located at the system’
start, the air mover pushes air through the system and the system operates under pressure
• When located at the system’s end, the air mover pulls air through the system and the
system runs under vacuum. By controlling the pressure or vacuum and airflow inside the
system, the system can successfully transfer materials.
4. Why Pneumatic conveying?
Introduction
•A conventional mechanical conveying system runs in a straight line, with minimal
directional changes, and each directional change typically requires its own motor and
drive. The mechanical conveying system may be open rather than enclosed, potentially
generating dust. It also has a relatively large number of moving parts, which usually require
frequent maintenance. The system also tends to take up a lot of valuable real estate in a
plant.
• On the other hand, a pneumatic conveying system uses a simple, small-diameter pipeline
to transfer material. The pipeline can be arranged with bends to fit around existing
equipment, giving the system more layout flexibility, and the system also has a relatively
small footprint. The system is totally enclosed and typically has few moving parts as it is
electronically managed.
6. Basic Components:
Introduction
Major pneumatic system components include:
1. Pressure blowers and vacuum pumps with integral sound enclosures
2. Rotary airlock valves
3. Transfer line including piping, elbows; divert valves (flex-tube diverters, wye-diverters,
plug diverters and other line diverter configurations).
4. Filter receivers
5. Cyclone separators
6. Gain-in-weight and loss of- weight batching systems
7. Dust collectors and bin vents
8. Controls and electrical equipment
9. Silos, day bins and other storage vessels
Rotary Valve:
9. Types of Pneumatic Systems:
Introduction
Three basic systems that are used to generate high velocity air stream:
•Suction or vacuum systems, utilizing a vacuum created in the pipeline to draw the
material with the surrounding air . The system operated at a low pressure, which is
practically 0.4–0.5 atm below atmosphere, and is utilized mainly in conveying light
free flowing materials.
•Pressure-type systems, in which a positive pressure is used to push material from
one point to the next. The system is ideal for conveying material from one loading
point to a number of unloading points. It operates at a pressure of 6 atm and
upwards.
•Combination systems, in which a suction system is used to convey material from a
number of loading points and a pressure system is employed to deliver it to a
number of unloading points.
11. Dilute Phase
Introduction
•The dilute-phase conveying system relies on the airstream’s velocity to pick up and
entrain each particle , keeping the particles in suspension throughout the conveying
line.
•It operates at a relatively high velocity at a relatively low pressure differential.
•The pickup velocity at the system’s start (that is, the airstream velocity at which
material is picked up and entrained at the material feed point) is generally considered
the system’s most critical area, because the air is at its lowest speed in the entire system
at this point. Because the material is dropping from a static state into the airstream
below it , the material must immediately become entrained. The air speed required to
pick up the material depends on each particle’s size and density, but can range
from3,000 to 8,000 fpm.
• The air mover must also be able to overcome the flow resistance caused by the
frictional loss of the air and material against the conveying line’s inside wall.
13. Dense Phase:
Introduction
•An ideal dense-phase conveying system would extrude material with enough pressure to
transfer it in one long, continuous piece through the pipeline’s entire length, just like a
continuous length of ground meat inside a sausage casing. But with dry bulk materials like
powders and granules, this usually isn’t possible because of the material’s high frictional
resistance against the conveying line’s inside wall. Instead, air and material flows through
the line in any of several patterns (including various forms of two-phase flow and
slug flow).
•While various dense-phase conveying system types are available, all uses are relatively
high pressure differential with a relatively low air velocity. The most common dense-
phase system type, provides batch transfer using a transporter (also called a blow tank or
pressure tank). In this system ,material from a storage vessel is loaded by gravity into the
transporter. After the transporter is full, its material inlet valve and vent valve are closed
and compressed air is metered into the transporter. The compressed air extrudes the
material from the transporter into the conveying line and to the destination . Once the
transporter and conveying line are empty, the compressed air is turned off and the
transporter is reloaded .This cycle continues until all the material required for the process
has been transferred.
15. Categorizing when a pneumatic conveying
Introduction
system is operating in dilute phase or dense
phase?
Most dilute-phase pressure systems operate below15 psi
(typically between 4 and 8 psi), while most dense-phase
pressure systems run above 15 psi.
•Most dilute-phase vacuum systems operate below 12
Inches mercury (typically between 8 and 12 inches mercury),
while most dense-phase vacuum systems run
above 12 inches mercury (typically between 12 and 14
Inches mercury).
•Depending on the conveyed material, most pressure and
vacuum dilute-phase systems have an air velocity between
3,500 and 9,000 fpm and most pressure and vacuum dense-
phase systems have a 3,000-fpmor lower air
velocity.
• In a dilute-phase system, the material velocity is nearly
the same as the air velocity. In a dense-phase system, especially
one with slug flow, the average material velocity
is much slower than the air velocity. In either system, the
material can’t move faster than the air.
