“What does process engineering mean?"
-By Pipetech | Published on April 21, 2021
Process engineering has its origins in the manufacture of food, medicines, clothing, materials, and building materials by craftsmen and in design engineering. Their ingenuity, experience, and skill gave birth to the processes on which process
engineering is based. Step by step, they created products from raw materials.
The aim of the craftsmen was and is the sale of consumer goods. Technicians develop
machines that take over, facilitate or accelerate individual work processes.
"The technical and economic implementation of all processes in which substances are
changed in terms of type, properties, and composition and plant".
The goal of the technician is to sell machines. Scientists investigate the causes that
bring about metabolism.
Your goal is to find the general laws of nature.
Process engineers line up machines and devices and convey the substances from
machine to machine. This creates a system in which, step by step, raw materials are
turned into products.
The prerequisite is that there is a machine or apparatus for each work step, that
conveyor technology is available, and that energy sources can be used to maintain the
operation of the system.
The inspecting eye of the craftsman, who watches over the result with every work
step, and his diligence, which avoids accidents, are replaced by measurement and
What is process engineering?
Process engineering is a branch of engineering focused on manufacturing and
Professionals in this field combine principles of physics, biochemistry, and mathematics to develop more efficient production processes. For example, process engineering can be used to determine the best way to turn an
existing restaurant into a franchise. This can range from sourcing raw materials to the
type of accounting software used to track sales.
It can also be used to evaluate
different methods of harvesting and extracting peanut oil to get the highest quality
product at the lowest price.
The field of process engineering is relevant to many industries. It is widely used in
food and beverage production, and can also be applied in sewage treatment and water
distribution wide range.
Process engineers may also work in facilities producing thermoplastics, pharmaceuticals, or cosmetics.
Process engineering is also used in power
generation. It helps companies find the best ways to extract materials and turn them
into fuel with minimal damage to the environment.
Those wishing to pursue a career in process engineering will often need to obtain a
graduate degree in chemical engineering or a related field.
While some universities
offer process engineering programs, many students will limit themselves to chemical
engineering or other larger fields.To be successful in this industry, applicants must
possess strong technical and
scientific skills as well as a sense of creativity.
A creative eye can be helpful in
finding new solutions or techniques that can improve a manufacturing process. Process engineers can work directly for industrial facilities, although some act as

The application areas of process engineering, the chemical industry, the food industry, the pharmaceutical industry, and the paper industry as well as areas of waste
management, metallurgy, textile industry, and the building materials industry. On the basis of the natural sciences, which have provided the laws for the applied
processes, process engineering can be divided into the areas

organize. In process engineering systems, processes from different areas are usually
combined.Process engineering tasks
The task of engineering is to find generally applicable laws for the interaction of
components and to compile requirements for technical devices that are supposed to
fulfill specific functions. This distinguishes it from natural science that has achieved
its goal by formulating a general law.
The aim of process engineering, according to its definition, is the development of
methods for converting substances and the formulation of specifications for their
technical implementation. This results in the following tasks for process engineering:
Planning the processing step
Selection or development of the required apparatus and machines
Determination of the methods for
Energy supply solutions
Determination of the required measurement, control, and regulation
Precautions to avoid accidents
process safety services
current processes recheck
innovations in process engineering conference
process data analytics

we have very senior process engineers at work.
The processing steps are compiled on the basis of the results of laboratory tests or on
the basis of existing experience from industry and trade. In order to transfer these
results and experiences to large-scale plants, trials with pilot plants on a smaller scale
are often necessary.
The individual conversions of substances take place in the apparatus and machines. Machines differ from apparatuses in that machines contain driven, moving parts, while in apparatuses chemical reactions, biological processes, or energetic processes
take place without the involvement of driven device parts.How the substance is
transported depends primarily on the physical state of the
substance in question. Gases and liquids can be guided through pipelines with the help
of compressors and pumps; for solid substances, for example, blowers, conveyor belts
or screw conveyors, and rotary valves are used.
Energy is required to drive machines, as auxiliary energy for fittings, for heating or
cooling, and for operating measurement, control, and regulation technology. Electric
energy, hydraulic oil, compressed air, and heat transfer media such as steam, hot
water, or cooling water are used.
The measurement, control, and regulation technology makes it possible to control the
process and the process variables
Safety equipment to avoid accidents is particularly necessary where dangerous
substances or large amounts of energy are handled. Hazardous substances are:
corrosive, irritating to the sk
toxic, harmful or
Large amounts of energy are mainly stored in devices with high operating
temperatures, pressure vessels, and steam boilers.
They can also be released through
chemical reactions. If the process generates waste that contains dangerous substances, it must be disposed of in an environmentally friendly manner.
Chemical process engineering
Chemical process engineering deals with the conversion of substances through
chemical reactions. Either individual substances are to be combined with one another
by synthesis or substances are to be split into their constituent parts. In this area of
process engineering, chemistry is technically implemented.
The processes take place in reactors. Theoretical considerations are based on the
model concepts of ideal stirred kettles, stirred kettle cascades, and ideal flow tubes. In
the stirred tank, the reactants are mixed with one another by the stirrer until the
required substances are created.
The machine is then emptied and refilled. This procedure is known as a batch
operation. For continuous operation, several stirred kettles are cascaded one behindthe
other, so that raw materials are continuously consumed and end products were
The substances mix in the flow pipe due to turbulence that occurs when the flow
velocity exceeds a limit value (Reynolds number) that is dependent on the material
properties and the pipe cross-section.
Most chemical reactions take place with the release of heat (exothermic) or with the
consumption of heat (endothermic). In order to maintain the optimal temperature for
the reaction, cooling or heating is installed.
Mechanical Process Engineering
The separation or production of heterogeneous mixtures of substances and the
crushing or joining of solids are tasks of mechanical process engineering.
Chemistry often supplies the required substances in a mixture with auxiliary materials
that were required for production or with non-usable reaction products.
If the required substance forms its own phase, it can be separated mechanically from
the substance mixture.
Depending on the physical state of the constituents of the mixture, filters, centrifuges, cyclones (dust separators), separators, separators, or settling basins are used.
Many properties of substances depend on the degree to which they are broken down.
If products are required in a coarse-grained state or in the form of powder, they can be
ground or broken. Since these processes always produce a spectrum of different grain
sizes, the crushing is often followed by sieving or sifting. During the sifting process, an airstream blows the lighter components into a collecting device provided.
The intended handling of the finished
products sometimes requires the substances to
be combined into compressed materials. For this purpose, the components are mixed
with one another if necessary and, if necessary, pressed into molds together with a
Thermal Process Engineering
Thermal processes are required for the separation of homogeneous mixtures of
These include distillation, multiple distillations ( rectification ), extraction, absorption, and adsorption.
These processes are often carried out in packed
columns. The separation of mixtures of substances with the help of membranes is also
assigned to thermal process engineering.
The basis for the distillation is the different vapor pressures of the components of a
Since, in relation to the vapor pressures, part of the higher-boiling component is
always contained in the vapor and part of the lower-boiling component in the liquid, simple distillation is often not sufficient to obtain the required substance in the
Then rectification is used, in which steam and liquid are brought into contact with one
another in counter current.
The vapor is enriched with the lower-boiling component
and the liquid with the other.Extraction takes advantage of the different solubility of
substances in a solvent. The
solvent absorbs one component of the mixture. The solution is then separated from the
mixture and then the solvent is separated from the extracted substance.
During absorption, components of gas mixtures dissolve in a liquid solvent. This
process is used, for example, for gas scrubbing.
Adsorption is the accumulation of components from liquids or gases on the surface of
a solid. This removes substances from liquids or gases in a targeted manner. The goal
is either to recover the deposited substance or to purify the substance mixture.
Electrochemical process engineering
Most salts consist of electrically positively charged metal ions and electrically
negatively charged acid residue ions. In the electric field, the ions move in thedirection of the oppositely charged electrodes.
If a closed circuit is established, the negative anions migrate to the positive anode and
give off electrons there. So there is oxidation. The positive cations migrate to the
negative cathode and take up electrons there.
The process is known as reduction and causes metals to deposit on the cathode. In this
way, the electrically conductive surfaces of workpieces are coated with metals. The
opposite process is used in batteries to generate electrical voltages with the aim of storing energy.
Bioprocess engineering uses metabolic processes in microorganisms and plants to
convert substances. The processes taking place are summarized under the term
Mainly the metabolism of yeast, bacteria, and algae and the effect of
enzymes are used. Enzymes are biologically active substances that support
