Process technology is when a product is manufactured from a raw material by using chemical, biological or physical processes.
Process technology can be viewed as the time between the production of a raw material and the manufacture of a product. The number of processes that are involved plays no role here. A good example is the manufacture of various metals from iron ore. Or petroleum, which has to be processed so that various end products can be manufactured using process technology. Process technology uses processes to modify more than just raw materials. This can include recyclable materials for instance. Especially in today's "green environment",process technology is utilized to process renewable raw materials , or bioenergy as it's called. This can involve different grains and other raw materials such as rape seed, from which bioenergy can be produced through various processes.
Process technology is not limited to a single process. It can be classified into five different process technologies, all of which involve their own process. First, there is thermal process technology , which deals with distillation. In contrast to thermal process technology, chemical process technology relies on chemical processes such as hydrolysis. Electrochemical process technology utilizes electrochemical processes such as the synthesis of various chemicals. Process technologies based solely on biological processes focus more on the use of bacteria, fungi or yeast.
Every process technology brings advantages and disadvantages. For this reason, the process technology must be selected on a case by case basis. Companies frequently utilize various process technologies to achieve the optimum result.
Hydrolysis uses a chemical process to split water into hydrogen and oxygen. Hydrolysis also involves the chemical separation of crystallization water. The opposite of hydrolysis is dehydration synthesis, which as the term implies involves the splitting of hydrogen instead of water.
The application of phosphoric or sulfuric acid as catalysts in hydrolysis causes alcohols to react for instance. The water then separates from the alcohol through the hydrolysis process. Hydrolysis can also be induced by using zinc chloride. Viewed on a large-scale, hydrolysis can also be activated at a specific pressure, which triggers the hydrolysis during the vapor phase. Alcohols frequently react with one another during hydrolysis. This hydrolysis process creates one molecule from two molecules of ethanol alcohol during the vapor phase at a temperature of 260°C. All of this can be triggered through hydrolysis.
### invalid font number 31506 In addition to acetic anhydride, which is produced by hydrolyzing acetic acid, hydrolysis is also used to produce phthalicanhydride from phthalic acid. These processes should be carried out only by trained chemists and physicists. Some processes are extremely complex and can trigger various side effects if carried out improperly. If the human body is exposed to excessive levels of acid during a process, it can result in damage to the respiratory tract.
Hydrolysis and process technology work hand in hand. A wide range of industries rely on hydrolysis for producing a variety of materials, which makes hydrolysis ideally suited for manufacturing processes.
This special field revolves around processes for modifying material properties (milling, cooling), composition (filtration, distillation) and type (oxidation, hydration).
Valuable information is available on a broad range of technologies including material separation, laser processes, measuring techniques and robot engineering in addition to testing methods and coating and materials analysis processes.
A new method that creates large-area patterns of three-dimensional nanoshapes from metal sheets represents a potential manufacturing system to inexpensively mass produce innovations such as "plasmonic metamaterials" for advanced technologies.

Researchers have developed a coating technique that they plan to use to protect tur- bine engine and waste incinerator components against heat and oxidation. A topcoat from micro-scaled hollow aluminium oxide spheres provides heat insulation, in the lab, already proved more economical than conventional techniques.
Gases don’t conduct heat as well as solids do. Cellular or aerated concretes take advantage of this effect, which experts call “gas-phase insulation”.24.11.2014 | Read more
What began as research into a method to strengthen metals has led to the discovery of a new technique that uses a pulsing laser to create synthetic nanodiamond films and patterns from graphite, with potential applications from biosensors to computer chips.
"The biggest advantage is that you can selectively deposit nanodiamond on rigid surfaces without the high temperatures and pressures normally needed to produce...06.11.2014 | Read more

Nondestructive tests find defects that remain hidden to the naked eye, for example, defective weld connections, cracks in the material, voids or inclusions. Fraunhofer IZFP is currently preparing standardization of inductively excited thermography, a novel nondestructive inspection method. This procedure is to be configured as a replacement for magnetic particle testing.
The industrial demand for manufacturing-accompanying nondestructive inspection by standardized methods has grown steadily in recent years. Compared to...09.10.2014 | Read more
Incredibly light and holds up in collisions – but often impossible to weld: this characterizes ultra-high-strength chromium steels that, thanks to their high carbon content, could not be reliably bonded together by laser until now. At this year’s EuroBLECH, the International Sheet Metal Working Technology Exhibition, the Fraunhofer Institute for Laser Technology ILT will use a B pillar to show how laser welding can be reliably used on press-hardened, martensitic chromium steels.
Within the scope of the research project SECOMAL, the Fraunhofer Institute for Laser Technology ILT in Aachen has determined process parameters and process...02.10.2014 | Read more
