The document discusses propane dehydrogenation (PDH) as an economically attractive process for producing propylene from propane. PDH involves reacting propane over a platinum catalyst at around 650°C and atmospheric pressure to yield about 90% propylene. The process recovers hydrogen and purifies the propylene product. An economic analysis found that PDH yields high internal rates of return in the US and China due to low-cost propane from shale gas and imports, respectively, but is less favorable in South America and Europe.
Refrigeration and air conditioning
Refrigeration and air conditioning systems use a refrigeration cycle to remove heat from an enclosed space and lower its temperature. The refrigeration cycle involves compressing a refrigerant vapor, condensing it into a liquid, expanding the liquid to produce cooling, and evaporating the liquid to remove heat. Common applications of refrigeration include cooling food in refrigerators and preserving temperature-sensitive substances like vaccines or hormones. Proper heating, ventilation, and air conditioning systems are also important for manufacturing pharmaceuticals by maintaining environmental conditions, preventing contamination, and protecting personnel comfort and health.

Refrigeration & Heat PUmps.pptx
Refrigerators and heat pumps are essentially the same device and differ only in their objectives. A refrigerator's objective is to remove heat from the cold medium, while a heat pump's objective is to supply heat to a warm medium. Both use the vapor compression refrigeration cycle which involves five basic components - a refrigerant, compressor, condenser coils, evaporator coils, and expansion device. The refrigerant absorbs heat inside the fridge/building and is compressed, releasing heat outdoors in the condenser coils, before repeating the cycle. Heat pumps transfer heat between outdoors and indoors using this cycle to provide both cooling and heating with one system.

TEST RIG FOR HYDRAULIC FLUID (A3987) - NEOMETRIX DEFENCE
PROJECT: TEST RIG FOR HYDRAULIC FLUID (A3987)
The test rig is used to test the anti-wear properties and the aging
behaviour of hydraulic fluids under defined and reproducible
conditions. For this purpose, a vane pump Vickers 35VQ25A-11*20
for ASTM D6973-2014 and a Bent Axis type axial piston pump
A2F10 for JCMAS P 045 are used as test objects. The subsequent
investigation of the wear inserts and oil condition then allows
conclusions about the performance of the tested fluids, especially
their ability to avoid wear and resist oxidation. The modern and
ergonomically designed test rig meets all the specifications of the
European Machinery Directive 2006/42/EG to a high standard or
equivalent Indian Standard. The test rig is used to determine the
wear characteristics and oxidation/ aging of non-petroleum and
petroleum hydraulic fluids. For this purpose, a rotary vane pump
generates a test pressure under specific boundary conditions. The
result obtained is the total mass loss from the cam ring and the ten
vanes (ASTM D6973-2014) after the test. For indicating oxidation
stability or aging behaviour of hydraulic fluids this test bench, uses a
bent axis pump A2FO10 and a pressure relief valve DBDS 10
K1X/400V as load at high temperatures. The test takes place under
the influence of air and a copper catalyst. This procedure allows for
an accelerated aging rate using a real hydraulic component. The test
rig parameters meet the specifications according to ASTM D6973-
2014 and JCMAS P 045. Additionally, it is capable of carrying out the
evaluation of hydraulic fluid for frictional characteristics and energy
efficiency performance under indigenously developed and
industrially simulated test methods by varying load, speed,
temperature, pressure, flow rate etc.

Harnessing WebAssembly for Real-time Stateless Streaming Pipelines
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker. These pipelines are adept at managing low-latency, high-data-volume scenarios.
TIME DIVISION MULTIPLEXING TECHNIQUE FOR COMMUNICATION SYSTEM
Time Division Multiplexing (TDM) is a method of transmitting multiple signals over a single communication channel by dividing the signal into many segments, each having a very short duration of time. These time slots are then allocated to different data streams, allowing multiple signals to share the same transmission medium efficiently. TDM is widely used in telecommunications and data communication systems.
### How TDM Works
1. **Time Slots Allocation**: The core principle of TDM is to assign distinct time slots to each signal. During each time slot, the respective signal is transmitted, and then the process repeats cyclically. For example, if there are four signals to be transmitted, the TDM cycle will divide time into four slots, each assigned to one signal.
2. **Synchronization**: Synchronization is crucial in TDM systems to ensure that the signals are correctly aligned with their respective time slots. Both the transmitter and receiver must be synchronized to avoid any overlap or loss of data. This synchronization is typically maintained by a clock signal that ensures time slots are accurately aligned.
3. **Frame Structure**: TDM data is organized into frames, where each frame consists of a set of time slots. Each frame is repeated at regular intervals, ensuring continuous transmission of data streams. The frame structure helps in managing the data streams and maintaining the synchronization between the transmitter and receiver.
4. **Multiplexer and Demultiplexer**: At the transmitting end, a multiplexer combines multiple input signals into a single composite signal by assigning each signal to a specific time slot. At the receiving end, a demultiplexer separates the composite signal back into individual signals based on their respective time slots.
### Types of TDM
1. **Synchronous TDM**: In synchronous TDM, time slots are pre-assigned to each signal, regardless of whether the signal has data to transmit or not. This can lead to inefficiencies if some time slots remain empty due to the absence of data.
2. **Asynchronous TDM (or Statistical TDM)**: Asynchronous TDM addresses the inefficiencies of synchronous TDM by allocating time slots dynamically based on the presence of data. Time slots are assigned only when there is data to transmit, which optimizes the use of the communication channel.
### Applications of TDM
- **Telecommunications**: TDM is extensively used in telecommunication systems, such as in T1 and E1 lines, where multiple telephone calls are transmitted over a single line by assigning each call to a specific time slot.
- **Digital Audio and Video Broadcasting**: TDM is used in broadcasting systems to transmit multiple audio or video streams over a single channel, ensuring efficient use of bandwidth.
- **Computer Networks**: TDM is used in network protocols and systems to manage the transmission of data from multiple sources over a single network medium.
### Advantages of TDM
- **Efficient Use of Bandwidth**: TDM all

Comparative analysis between traditional aquaponics and reconstructed aquapon...
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

Refrigeration system ppt
- 3. Refrigerants such as R-32 and other HFC are used as a cooling medium in appliances such as Domestic and Automotive Air Conditioners, Refrigerators, Chillers, Deep Freezers. This Refrigerant is transferred in to liquid form in the Gas compressors but because of its Variant Physical Characteristics with Temperature and Pressure these refrigerants are not completely filled in the compressors and they remained as vapors in the supply tank and would cost a substantial amount to the OEMS as Wastage. The Refrigerant Decanting/Recovery and recharging system is a HIGH PRESSURE facility for recovery and refilling of refrigerant in the main filling line.
