This document provides standard operating procedures for cleaning and sanitizing fermenters and bright tanks at a pilot brewery. The cleaning in place (CIP) procedure uses two cycles, first with an acid and surfactant to remove beerstone and loosen soils, followed by a caustic cycle to further break down protein soils. Key steps include attaching hoses, adding chemicals to the tanks, running cleaning cycles for 30-60 minutes, inspecting tanks, and rinsing before the sanitizing in place process which involves heating and purging tanks with carbon dioxide. Safety precautions are outlined when handling chemicals, hot water, and pressurized tanks.
Pumps and Cavitation
The document discusses cavitation in high energy pumps. It provides an overview of cavitation, how to detect it, and what causes it. Cavitation occurs when vapor bubbles form in a liquid due to a local pressure drop below the vapor pressure. When these bubbles collapse as pressure increases, it can cause damage to pump components from micro jets of liquid. The document explains factors like net positive suction head (NPSH) required by pumps and available from system components in order to prevent cavitation. It also discusses how cavitation affects pumps and methods for detecting potential damage.

Problems faced in conrol valves ppt
Control valves can experience several problems including cavitation, flashing, noise, and choked flow. Cavitation occurs when the pressure drops below the vapor pressure, causing vapor bubbles that implode and cause damage. Flashing happens when downstream vapor pressure is lower than upstream, causing partial vaporization. Noise stems from mechanical vibration, cavitation bubble implosions, and turbulent gas flow. Choked flow is when the flow cannot increase despite lower downstream pressure because the fluid velocity at the venturi reaches sonic speed.

Ammonia leak test
The document describes methods for detecting leaks using ammonia as a tracer gas. There are two main test methods - the vacuum method and the pressure method.
The vacuum method involves evacuating the space to be tested to 70 millibar and introducing ammonia gas. Ammonia sensitive developers are then used to detect any leaks. The pressure method uses a mixture of nitrogen and 15% ammonia to pressurize the space to 2.3 bar. Developers are again used to detect leaks during a 10-12 hour response time.
Safety precautions must be taken when using ammonia, which is toxic and flammable. Developers that can be used include ammonia sensitive paper, paint and spray,

Sewer appurtenances
This document provides information on sewage apparatus types including manholes, flushing tanks, and catch basins. It describes manholes as access points for sewer inspection and maintenance, with spacing guidelines based on pipe diameter. Manhole types include shallow, normal, and deep. Flushing tanks are used where sewers lack self-cleansing velocity, and come in hand operated or automatic styles. Catch basins admit clear rainwater to combined sewers while preventing grit and debris from entering.
Valves
Valves have different types and functions depending on the type of service. The main types are on-off valves like gate valves, plug valves, and ball valves which are used to start and stop flow. Throttling or regulating valves like globe valves and butterfly valves are used to control the flow rate. Check valves prevent backflow and include swing check valves, lift check valves, and ball check valves. Pressure relief valves like safety valves and relief valves are used to release excess pressure to protect systems. Control valves combined with actuators, controllers and sensors are used for automatic pressure control.
Control valve ppt
This document discusses control valves, including their applications in flow, level, pressure, and temperature control. It defines control valves as valves that are remotely controlled to maintain parameters like flow rate, level, pressure, and temperature.

Turbine safety protection
In modern power plants, extensive protections and interlocks are provided to isolate faulty equipment without causing further damage and allow reserve equipment to start up automatically. Protections detect abnormal parameters and trip equipment to prevent major damage. Interlocks make equipment states dependent to prevent incorrect operation. Protections include tripping the turbine for issues like high/low steam pressure, temperature, exhaust hood temperature, axial shift, differential expansion, eccentricity, pump failures, and low lubricating oil pressure.
CF lab extraction hood
This document summarizes the specifications of an extraction hood in a coalfields laboratory. It has an entrance area of 0.74m2 and an extraction velocity of 2.9m/s. Principles of good hood design include enclosing operations to reduce airflow needs, locating the hood to move contaminants away from workers and capture contaminants at their source. The current layout shows pollutants escaping the hood, but remedial action would move pulverizers directly under the hood. Future plans are to increase the hood size to extend over a crusher and increase the capture velocity.
Basic Control Valve Sizing and Selection
In this day and age of automated computer control valve sizing, the logic and theories behind it are invisible. In his presentation, Al Holton of Allagash Valve & Controls will look at the basic principles that apply and how they affect the application and installation of a wide range of control valve types. He will also review the reasoning behind valve type selection.
Main air compressors PPT.pptx
The document discusses marine air compressors used on ships. It describes the various uses of compressed air on ships, including starting main/auxiliary engines, automation/control, pneumatic tools, fog horns, and more. It provides details on compressor requirements, operating principles, intercooling benefits, maintenance procedures, and common issues like low efficiency.
Calculation Of Pump Head
Centrifugal pumps work by using an impeller to increase the pressure and flow of a liquid. Liquid enters the center of the impeller and is accelerated outward by the curved blades of the impeller. This increases the pressure and flow of the liquid. Calculating the required head of a centrifugal pump involves accounting for static head, pipe friction losses, and adding additional head for safety. Proper pump selection is based on matching the required head and flow rate to the pump performance curves. Cavitation and ensuring adequate Net Positive Suction Head (NPSH) are also important considerations for centrifugal pump operation.

100++-interview questions and answers on steam turbine.pdf
100++-interview questions and answers on steam turbine
Is it possible to have a negative absolute pressure?
No, absolute pressure is measured with reference to a perfect vacuum so it is impossible for it to go negative. You can only measure negative pressure between two different pressures. For example if you allow atmospheric air to gradually flow into a vacuum vessel and measure pressure inside relative to outside it will show a negative pressure reading.
What type of problems do you face in steam turbines related to vacuum?
Problems such as:
· Low vacuum
· High exhaust pressure
· High exhaust temperature
· Higher specific steam consumption
· More cooling water circulation
· Hot well level variation
How do you create vacuum in steam condensers?
Vacuum is created in condenser by steam jet ejectors, where high pressure 8–12 kg/cm2 steam is passed through nozzle which is connected to air line from condenser. This creates high negative pressure there by evacuating air from condenser.
Generally there are Two Types of Ejectors:
Hogger Ejector: Initially this ejector is used for pulling vacuum. It has steam and air lines connections, steam is vented directly into atmosphere. It consumes more steam than main ejectors. It requires 20–30 minutes to create 85% of operating vacuum.
Main Ejector: It comes with first stage and second stage. Air line from surface condenser is given to 1st stage then again air from 1st stage is collected and discharged into 2nd stage. 2nd stage ejector has air vent line.
It consumes less steam than hogger ejector. Generally an ejector come with 1W + 1S i.e. one working and one stand by.
Also vacuum pumps called liquid ring vacuum pumps are used to create vacuum in condensers. Which consume less energy than steam jet air ejector
How does low vacuum affect on turbine speed?
Lower vacuum creates back pressure on turbine blades and rotors. So in emergency, vacuum breaker valve is opened to bring down the turbine speed to zero in minimum time to avoid any further damages.
What is the effect of low vacuum & high exhaust pressure on steam turbine performance?
Low vacuum or high exhaust pressure & high exhaust temperatures lead to more steam consumption to generate unit power.
What are the potential reasons for lower vacuum in steam condenser?
· More condenser load than design
· Lesser amount of cooling water circulation in condenser
· Higher atmosphere temperature
· Location of the steam condenser at higher elevations.
· More exhaust temperature
· Air leakages in the system
· Lesser efficiency of steam ejector or vacuum pump
· Ejector inter condense (1st stage) condensate seal break
· Lesser pressure & temperature of motive steam at ejector inlet
· Worn out ejector nozzles
· Improper quality of motive steam
· Variation in condenser inlet & outlet cooling water temperatures
· Operation of Turbine at lower load
· Lower gland seal steam pressure

Introduction, Types, Functions, pros and cons
presentation on hydraulic pump
The document discusses centrifugal pumps. It begins by defining what a pump is and its main purposes and categories. It then focuses on centrifugal pumps, describing their basic components as a casing, impeller, and driver/motor. It explains how centrifugal pumps work by using centrifugal force to increase pressure and flow of a liquid. The document outlines advantages like simplicity and lower costs, and disadvantages like inability to handle highly viscous liquids. It provides examples of impeller types and compares centrifugal pumps to other pump types. Overall, the document provides a high-level overview of centrifugal pump components, working mechanism, characteristics, and comparison to other pumps.
Cold Water Supply Distribution In Building
The document discusses the operating principle of air pressure water distribution systems. It begins by explaining that air is compressible while water is not, allowing air pressure in a tank to reach 15 psi and lift water up to 10.5 meters. It notes the ideal pressure range is 20-40 psi. Automatic controls regulate air compressors to maintain adequate pressure. Advantages include low cost while disadvantages include electricity dependence. The document also examines direct upfeed and triplex pump systems as well as factors affecting water pressure and sizing water pipes.
reciprocating pumps
Positive displacement pumps work by trapping a fixed amount of fluid and forcing it to discharge. There are three main types: reciprocating pumps use pistons, diaphragm pumps use flexible diaphragms, and linear pumps use linear motion. Reciprocating pumps are commonly used for high pressure applications like well services. Diaphragm pumps are suitable for handling corrosive or abrasive liquids since only the diaphragm and valves contact the fluid. Positive displacement pumps can handle high viscosity liquids efficiently and are used widely in industries like oil and gas, mining, and more.
Presentation on pump Roll 132031-132040
This document provides information about pumps, including their classification, main components, and operating principles. It discusses two main types of pumps - centrifugal pumps and positive displacement pumps. For centrifugal pumps, it describes how the impeller increases the velocity of the fluid to generate pressure and flow. It also explains the priming, startup, and operation procedures for centrifugal pumps. Examples of pump applications like boiler feed pumps, fire pumps, and pool pumps are listed at the end.
Air lift pump
The document discusses an air lift pump, which uses compressed air to lift water from deep wells or sumps. It has no moving parts submerged in water. The air lift pump works by injecting compressed air through nozzles into the bottom of a delivery pipe submerged in the water. This causes the air-water mixture in the pipe to become less dense than the surrounding water, rising up the pipe and discharging water at the top. While requiring no submerged parts and able to lift water through narrow boreholes, air lift pumps have low efficiency, limited flow rates, and cannot operate if the water level drops below a certain point. They are often used in deep, dirty wells to avoid clogging mechanical pumps.

Centrifugalpump
The document discusses centrifugal pumps, including their working mechanism, operation, advantages, and disadvantages. Centrifugal pumps use a rotating impeller to impart centrifugal force on liquid and increase pressure to pump water from a low point to a higher point. They are simple to operate but work best over a narrow range of conditions and cannot handle highly viscous liquids efficiently.
PRESENTATION ON PUMP RUET
The document provides information about pumps, including their basic functions, main components, classifications, and examples of applications. It discusses how pumps work to increase the energy of liquids and move fluids through mechanical action. Pumps are classified as centrifugal or rotodynamic pumps, which use a rotating impeller to increase fluid velocity, and positive displacement pumps, which work by filling and emptying cavities. Examples of positive displacement pump types include reciprocating, power, and steam pumps. The document also outlines the basic working procedure of a centrifugal pump and provides diagrams to illustrate pump components and operation.
Reciprocating pump
This document provides an overview of reciprocating pumps. It discusses the key components of reciprocating pumps like pistons, cranks, and valves. It describes different types of reciprocating pumps such as single acting, double acting, and multi-cylinder pumps. Specific pump types - plunger pumps and diaphragm pumps - are explained in more detail including their working principles, advantages, disadvantages, and applications. A comparison is made between reciprocating and centrifugal pumps. Finally, the advantages and disadvantages of reciprocating pumps in general are summarized.
Hydraulic Ram Made from Standard Plumbing Parts
A hydraulic ram can be assembled from standard plumbing parts to pump water to higher elevations. The document provides instructions on assembling the ram from fittings like pipes, tees, valves, and a pressure tank. It also provides guidance on adjusting the ram for proper pumping by tweaking the swing check valve angle or drive pipe length.
Reciprocatingpumps 130201084428-phpapp02
Positive displacement pumps work by trapping a fixed amount of fluid and forcing it into the discharge pipe. There are two main types: reciprocating pumps which use pistons and rotary motion to pump fluid, and linear pumps which use diaphragms or plungers to linearly displace fluid. Reciprocating pumps can vary the flow within each revolution while linear pumps provide nearly constant flow over a wide pressure range. Common applications of positive displacement pumps include agriculture, chemical processes, desalination, mining, and oil and gas industries.
Pumps, a prime mover, pumping system layout.ppt
This document discusses various types of pumps used to lift liquids from lower levels to higher levels. It begins with an overview of pumps in general, then discusses positive displacement pumps like reciprocating pumps. It describes the basic components and operating principles of centrifugal pumps like single-stage, multi-stage, and their casings. It also briefly covers other pumps like axial flow pumps, jet pumps, and valves used in pumping systems. The document provides detailed information on the classification and working of different types of pumps.
Troubleshoot and Root Cause Analysis - PRV
Being a sophisticated device, when Pressure Reducing Valve (PRV) is subjected to the harsh working conditions, there could be chances of choking up of the valve which eventually leads to disruption in the outlet pressure, noise, vibration and inadequate flow. Downtime goes up along with the maintenance cost. This presentation talks about common issues, the root cause analysis and troubleshooting the same.
3_Artificial_lift_systems.ppt
Artificial lift systems are used to increase production from oil wells that can no longer produce on their own. The main types discussed are rod pumping, progressing cavity pumping, electric submersible pumping, gas lifting, and plunger lift. Key factors in selecting a system include the well's production rate, depth, fluid properties, and economic considerations such as capital and operating costs. Performance is evaluated using productivity index curves, decline curves, and analyzing the impact of gas injection on flowing bottomhole pressure.
Water, Wells and Pumps
1. The document discusses different types of water wells and pumps, including dug wells, bore wells, and tube wells. It describes how wells are classified based on the type of aquifer supplying water and the construction method.
2. President Kalam's message emphasizes achieving energy independence for India by 2030 through increasing renewable energy sources like solar power from 5% to 25% of total power generation.
3. Solar photovoltaic technology converts sunlight directly into electricity using solar cells made of silicon. When light hits the solar cell, it knocks electrons loose and creates an electric current that can be captured.
