Process Heaters, Furnaces and Fired Heaters: Improving Efficiency and Reducin...Belilove Company-Engineers
A process heater is a direct-fired heat exchanger that uses the hot gases of combustion to raise the temperature of a feed owing through coils of tubes aligned throughout the heater. Depending on the use, these are also called furnaces or red heaters. Some heaters simply deliver the feed at a predetermined temperature to the next stage of the reaction process; others perform reactions on the feed while it travels through the tubes.
Several measurements were made to study temperature and chemical distribution inside a molten bath in a Tower Type & Reverberatory Type furnace. The furnace was an Aluminium scrap melting furnace and it was equipped with the “TSIT” which is Electromagnetic induction stirring of molten metal. The molten metal used for the experiment was an Al-Si alloy. There were 4 bath thermocouples installed inside the furnace which were used for measuring of the bath temperature in different places and depths of the bath. One more thermocouple measured temperature of the furnace roof. There were 3 different places chosen for taking samples to make chemical analysis. The data from the five thermocouples and the result of the chemical analysis of the 3 samples were compared and analyzed. The results show how the TSIT makes temperature and chemical homogeneity of the entire molten bath in a Reverberatory furnace during different technological operations.

Project of Introduction to Petroleum and Gas Engineering and Explanation of the cracking process and types.Cracking, as the name suggests, is a process in which large hydrocarbon molecules are broken down into smaller and more useful ones,The cracking products, such as ethene, propene, buta-1,3-diene and C4 alkenes, are used to make many important chemicals. Others such as branched and cyclic alkanes are added to the gasoline fraction obtained from the distillation of crude oil to enhance the octane rating.
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

value Bomb calorimeter
A bomb calorimeter is a device that is designed to measure th
amount of heat that is given off or taken in by a reaction.
It is designed to be isolated from the surroundings, meaning
no heat can leave or enter the device..
In order to accomplish this, the outside wall of the calorimeter
is a vacuum sealed wall similar to an insulated mug you might
carry coffee in. Inside the calorimeter is a vessel in which the
reaction occurs surrounded by a water bath. The temperature
the water bath can be monitored via thermometer.When a
reaction takes place in the calorimeter, the temperature of the
water bath changes. If an exothermic reaction occurs, the wate
bath temperature goes up. If an endothermic reaction occurs,
water bath temperature goes down.In an ideal calorimeter all t
heat exchange would take place with the water. However, in re
the materials from the calorimeter itself, the stainless steel, th
etc., exchange heat with the system as well. We can correct fo
using a heat capacity for the calorimeter in our calculations.Be
the heat is exchanged inside the calorimeter, we can set the t
zero

Heating of coal in absence of air to produce coke is called
carbonisation.
Types of carbonisation:-
• low temperature carbonization
• High temperature carbonisation.
Low temperature carbonisation(LTC):-
Heating of coal at temperature of 500-700℃ and the amount
of coke obtained is about75-80% of carbon and it contains
5-10%volatile matter.
High temperature carbonisation:-
Heating of coal at temperature 900-1200℃ and the amount of
coke obtained is about 98% of carbon and it contains only 1-3%
volatile matter.

BERGIUS PROCESS
The Bergius process is a method of production of liquid hydrocarbons
for use as synthetic fuel by hydrogenation of high-volatile
bituminous coal at high temperature and pressure.
• The coal is finely ground and dried in a stream of hot gas.
The dry product is mixed with heavy oil recycled from the process.
A catalyst is typically added to the mixture.
• The whole is heated with hydrogen at 450®C and under
pressure 200-250 atm for about 1.5 hours,during which hydrogen
combines with coal to form saturated hydrocarbons.
• The issuing gases are led to condenser,where a liquid resembling
crude oil is obtained,which is then fractionated to get
1.gasoline,2.middle oil,3.heavy oil.
• The middle oil is hydrogenated in vapour phase in presense of a
solid catalyst to yield more gasoline.The yield of gasoline is about
60% of thr coal dust used.
Fischer
Tropsch (FT) process, originally developed by Franz Fischer and Hans
Tropsch in early 1920s, is a series of chemical reactions that involve th
conversion of hydrogen and carbon monoxide into liquid
hydrocarbons by using a catalyst.
The FT process involves a catalytic chemical reaction in which
carbon monoxide (CO) and hydrogen (H2) present in the synthetic
gas are converted into hydrocarbons of different molecular weights
based on the following equation
Fischer-Tropsch Reactors
The reactions involved in the FT process are highly exothermic
therefore, the elimination of heat is important when designing a
commercial reactor. Three types of reactors are generally used for
FT synthesis:
Slurry bed reactor
Fluidized bed reactor
Fixed bed reactor

value KNOCKINGKnocking is a sharp sounds caused by premature combustion of
part of the compressed air-fuel mixture in the cylinder.
In a properly functioning engine , the charge burns with the flame
front progressing smoothly from the point of ignition across the
combustion chamber .
1)Knocking is generally caused in an old engines .
2) Knocking is due to auto-ignition of fuel in the cylinder during
power stroke.
3)Knocking is mainly caused by the “ deposits of carbon” on the
walls of the cylinder.
4) One should be noted that carbon deposits absorb heat and it
won’t release it. And it made the fuel auto-ignited before the spark
plug(SI engine).
5) When the fuel is auto-ignited before the spark plug, the fire from
below the TDC ( top dead centre) moves upwards and the spark from the spark
plug moves downwards , both coincides towards each other then it
causes the knocking

Reactors:
Moving bed reactors are reactors in which the catalytic material
flows along with the reactants and is then separated from the
exit stream and recycled.
General Information:
Usage Examples:
Moving bed reactors are catalytic reactors in which the catalyst
moves through the reactor along with the reactants.
They are open systems and operate at steady state .
Moving bed reactors are frequently used in wastewater
treatment processes.They can be tuned to the application by
selecting specific microbes, but these types of reactors are
very effective at nitrification, denitrification, and chemical oxygen
demand (COD) reduction processes.
