This lecture is all about the pumps, its components, need of pumping system, pumping system environment, classification of pump, pump characteristic curve, pump selection, affinity laws for pumps, and power requirement for pump.
This document was produced as part of my final year project of training to obtain a petroleum engineering diploma.
The aim of this project is to make a comparative study between continuous and intermittent gas lift systems based on real data from an oil well in Algeria, and to choose the system best suited to increase the production of the well.
This study was carried out by a manual design using the method of “fixed pressure drop” for the continuous gas lift system and “fallback gradient” method for intermittent gas lift system.
We were able to determine at the end of this study that the system best suited to the current conditions of our well would be the intermittent gas lift system and we also proposed that it should be combine with the "plunger lift " system in order to increase the efficiency of the intermittent gas lift system by eliminating problems linked to the phenomenon of" fallback " thus increase the production of our wells.
We are all familiar with the production systems through which reservoir fluids flow to reach our processing facilities. This is a journey characterized by complex multiphase flow phenomena that govern pressure and temperature changes along the way. A monumental amount of research and development work has been invested towards better understanding multiphase flow behavior over the past fifty years. Yet, many challenges remain as we strive to optimize ever more complex production systems fraught with difficult flow assurance issues. Just how good is the science? And more importantly, how does this impact our bottom line? This lecture will discuss key concepts of multiphase flow leading to the current “state-of-the-art” models used today. Looking towards the future, the science must be advanced to address areas of greatest uncertainty and align with trends in field development strategies. Recommendations will be presented covering the top 5 areas of research necessary for these purposes. The economic impact of multiphase operations will be illustrated using two examples that provide insight towards maximizing asset value.

Numerical analysis for two phase flow distribution headers in heat exchangerseSAT Journals
Abstract A flow header having number of multiple small branch pipes are commonly used in heat exchangers and boilers. In beginning the headers were designed based on the assumption that the fluid distribute equally to all lateral pipes. In practical situation the flow is not uniform and equal in all lateral pipes. Mal distribution of flow in heat exchangers significantly affects their performance. Non-uniform flow distribution from header to the branch pipes in a flow system will lead to 25% decrease in effectiveness of a cross flow heat exchanger. Mal distribution of flow in the header is influenced by the geometric parameters and operating conditions of the header. In this work the flow distribution among the branch pipes of dividing flow header system is analyzed for two phase flow condition. In the two phase flow condition, the effect of change in geometric cross sectional shape of the header (circular, square), inlet flow velocities are varied to find the flow mal distribution through the lateral pipes are investigated with the use of Computational Fluid Dynamics software. Keywords: circular, square headers and Computational Fluid Dynamics software. (CFD)
— The Coffee Leaf Miner-CLM and coffee rust are the main pests and coffee diseases, respectively. One of the rust and CLM handling ways is the preventive use of active ingredients of joint action (fungicide + insecticide) via soil. These products are generally evaluated for their efficiency in the chemical control of pests and diseases; however some of these products may promote a tonic effect by improving plant vigor. Thus, the objective in this work was to verify the influence of the phytosanitary products application on the rust and leaf miner control, on the coffee trees development and production. The assay was installed in Random Block-144 crop. Number of nodes per branch, productivity, incidence of rust and CLM were evaluated. There was no difference in the coffee trees growth submitted to the application of different phytosanitary products for the control of rust and leaf miner. The application of Thiamethoxan + Cyproconazole in november with a complementary application of Thiamethoxan in february were more efficient for the coffee leaf miner control and provided greater vigor and productivity to the coffee tree.

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Saudi Arabia stands as a titan in the global energy landscape, renowned for its abundant oil and gas resources. It's the largest exporter of petroleum and holds some of the world's most significant reserves. Let's delve into the top 10 oil and gas projects shaping Saudi Arabia's energy future in 2024.
2. Introduction
• There is a wide range of sizing methods for two-phase
separators, varying from the simple “back-of-the-
envelope” to the far more complicated
• several weaknesses associated with most of these
methods
1. Quantification of feed flow steadiness
2. Entrainment/droplet size distribution quantification
3. Velocity profile/distribution quantification
4. Separator component performance quantification
4. Separator
• The main objective is to remove droplets of a dispersed
phase from a second continuous phase.
• A secondary requirement is often for the separator to
have some capability to deal with intermittent
flow (slugging)
• Questions important in the sizing and performance
prediction
1. What is the flow pattern at the separator’s inlet?
2. How much of the dispersed phase (liquid droplets) is
present in entrained form?
3. What are the sizes of the droplets?
6. Flowpipe geometry
• What if the flow has changed direction, for example, at
elbows and fittings, or experienced other flow pattern
disruptions immediately upstream of the separator.
• Typical guidelines are:
1. Provide 10 diameters of straight pipe upstream of the
inlet nozzle without valves, expansions/contractions,
or elbows.
2. If a valve in the feed line near the separator is
required, it should only be a full port gate or ball
valve.
8. Entrainment cont-
• The degree of liquid entrainment is a function of the
following variables (among others)
1. Entrainment increases with increasing velocity
2. Entrainment increases with decreasing liquid
surface tension.
Pan and Hanratty (2002)
12. Inlet Device
• Main function of an inlet device
1. Maximization of gas/liquid separation efficiency based on
inlet feed conditions
2. Minimization of droplet shearing
3. Provision of good downstream velocity distributions in the
separated phases
Inlet momentum
14. Effect of the selected inlet device on downstream
velocity profiles without flow straightening devices
15. Gas Gravity Separation Section
• Primary function is to reduce the entrained liquid load
not removed by the inlet device.
• A secondary function is the improvement/straightening
of the gas velocity profile.
• Two approaches to sizing this part of the separator to
remove liquid droplets from the gas are the K method
(Souders-Brown equation ) and the droplet settling
theory.
• the droplet settling calculations aim at removing a
target liquid-droplet size (e.g., 150 μm) and all
droplets larger than the target size
19. Separator
Verticle separator :Using the droplet size
distribution and effective actual velocity
correlations,the terminal velocity equation can be
used to calculate the droplet removal efficiency of
the gas gravity separation section
Horizontal separator :
separation efficiency of droplets smaller than dp,100
21. Mesh Pads
• A methodology that can be used to quantify droplet
capture efficiency of a mesh-type mist extractor is as
follows:
1. Calculate the Stokes’ number (sometimes called the
inertial impaction parameter) from the following
equation
2. Calculate the single-wire removal efficiency
3. mesh-pad removal efficiency
23. Use of Different Mist Extractor
Types in Series
1. A mesh pad followed by a vane pack
2. A mesh pad followed by a demisting cyclone
bundle
• At high gas-flow rates, the mesh pad will be operating
above its capacity limit.
• The mesh pad provides good low-flow droplet
removal performance, while the secondary vane-pack
or demisting cyclone bundle provides high-flow
capacity with improved droplet removal performance
as a result of the larger droplets exiting the mesh pad
24. Liquid Gravity Separation Section
• The functions of the liquid gravity separation
section depend on the type of separator and its
application, including the following:
1. Degassing of the liquid.
2. Smoothing out of intermittent inlet flow surges
to provide steadier liquid flow to downstream
equipment/processing.
3. To maintain a liquid seal at the bottom of the
separator, a minimum requirement for
instrumentation layout and process control
25. Quantification of gas entrainment into
liquid by a plunging jet
1. Estimate the effective liquid-jet nozzle diameter.
2. Establish the length of the jet, which is typically the distance from the
inlet device outlet to the separator liquid level.
3. Calculate the effective jet velocity at the point where the jet enters the
liquid pool.
4. Calculate the jet Froude number.
5. Calculate the amount of gas entrained into the liquid pool by the jet.
6. Calculate the depth of penetration of bubbles by the plunging jet (the
release point of the bubbles).
7. Estimate the bubble size distribution.
8. Perform the bubble size separation calculations based on the separator
geometry, including whether vertical or horizontal, the flow rates,and fluid
properties. The calculations are analogous to those used for liquid droplet
settling in the gas gravity separation section
26. Handling Intermittent Flow
• If the slug/surge volumes cannot be quantified in advance with a
multiphase flow simulator, for example, the following approaches
provide allowance for intermittent feed flow behavior:
1. Inflate the steady-state flow rates, and size the vessel using
standard procedures. Table 6 provides typical flow-rate multipliers
based on the upstream feed supply configuration
2. Estimate the slug/surge volumes. This requires an understanding
of the various mechanisms that cause slugging and quantification of
the slug/surge volumes involved. In the absence of better
information, the slug size can be assumed to be from 3 to 5 seconds
of liquid-full flow at feedpipe velocity. In-plant separators
downstream of the inlet separation equipment would not be
expected to see large slugs. A slug size based on 1 sec of liquid-full
pipe at feed-flow velocity seems reasonable for these separators.
28. Conclusion
• The equations and methods that can be used to improve the
quantification of gas/liquid separation performance
compared with traditional techniques.
• The key aspects of the recommended methodology include
quantification of the following:
1. The amount of gas (liquid) entrained in the form of
droplets (bubbles)
2. The size distribution of the entrained droplets (bubbles)
3. The continuous phase (gas or liquid) velocities
4. Droplet (bubble) separation performance based on 1–3
above and the geometry of the separator
• Presented approach to gas/liquid separator design and
rating that more accurately reflects the physics involved.
