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.
It’s a familiar scenario – limescale in the electric kettle and coffee machine or water stains on the taps, these are problems which are not yet soluble in the household. The situation is however somewhat different in industrial systems: it is precisely in large-scale production with liquid media that so-called ‘fouling’ is often the cause of expensive cleaning cycles and thus of longer machine downtimes.
For example, the milk pasteurization line is stopped once again and cleaned after just one operating cycle because, for example, milk proteins have formed...01.04.2015 | Read more
Highly precise and stable surface coatings are essential for many applications, whether for eyeglasses, or for optics for lasers or telescopes. The project PluTO created a basic understanding of plasma-based coatings. The aim of the project PluTO+ is now to transfer these to industrial applications. For this, the Laser Zentrum Hannover e.V. (LZH) is working on controlling ion beam sputtering (IBS).
Up to now, IBS processes, in comparison to magnetron processes for example, could only be guided by using set parameters, but without online control....16.03.2015 | Read more
Instead of completely exchanging expensive components after wear and tear, these can be repaired using deposition welding. Up to now, a gas metal arc welding (GMAW) process has usually been used for deposition welding, with an average feed rate of five kilos per hour.
Since the dilution level is around 30 percent, several layers must be deposited, one on the other, until the protective covering is pure enough. Scientists at...11.03.2015 | Read more

Traditionally, plastic recycling processes involve using a lot of water. In order to avoid this waste, Ak Inovex from Mexico developed a new green technology that doesn’t require liquids, and has the capacity to process materials such as styrofoam, polystyrene and ABS (Acrylonitrile butadiene styrene) using the same type of customizable machinery.
The technology developed by Marco Adame, founder of Ak Inovex, can process more than 90 percent of any type of plastic, avoids water waste and reduces...05.01.2015 | Read more

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

Glass-fronted office buildings are some of the biggest energy consumers, and regulating their temperature is a big job. Now a façade element developed by Fraunhofer researchers and designers for glass fronts is to reduce energy consumption by harnessing solar thermal energy. A demonstrator version will be on display at Hannover Messe.
In Germany, buildings account for almost 40 percent of all energy usage. Heating, cooling and ventilating homes, offices and public spaces is expensive – and...

The IPH presents a solution at HANNOVER MESSE 2015 to make ship traffic more reliable while decreasing the maintenance costs at the same time. In cooperation with project partners, the research institute from Hannover, Germany, has developed a sensor system which continuously monitors the condition of the marine gearbox, thus preventing breakdowns. Special feature: the monitoring system works wirelessly and energy-autonomously. The required electrical power is generated where it is needed – directly at the sensor.
As well as cars need to be certified regularly (in Germany by the TÜV – Technical Inspection Association), ships need to be inspected – if the powertrain stops...
