Exchanger E-3 preheats feed to fractionator C-1 with bottoms from the same fractionator.
Cooling water is supplied mainly by recycle from cooling tower T-1 by pump P Electricity for all pumps and compressors, and steam for reboilers is produced from coal-fired power plant B The overall input to and output from the process is represented schematically in Figure 9.
Figure 9. Even if this were technically feasible, such a process would be uneconomical because of excessive capital investment in equipment, which would have to be essentially infinite in size to minimize transport gradients. Nevertheless, it is economical to modify existing processes to reduce energy consumption, and to design new processes to operate at higher CD thermodynamic efficiencies.
A second-law thermodynamic analysis identifies inefficient processes and the operations within these processes that are the most wasteful of energy, so that the process engineer can direct his or her efforts to conserving energy.
The system is the matter contained in the operating unit s on which the engineer wishes to focus.

Everything not in the system is in the surroundings. The boundaries of the system may be real or imaginary, rigid or movable, and open or closed to the transfer of matter between the system and the surroundings.
They refer to the boundary of the control volume as the control surface across which matter can flow. Batch, cyclic, and continuous processes are shown schematically in Figure 9.
Batch and cyclic processes are usually divided into a closed system or simply a system and surroundings; continuous processes are divided into an open system or control volume and surroundings. CD Figure 9. The division of a process into system and surroundings is the choice of the one performing the thermodynamic analysis.
Many choices are possible for a chemical process. For example, in Figure 9. More commonly, utility plants e.
This is shown schematically in Figure 9. The benzene-mixed xylenes plant is sufficiently complex that it is advisable to divide it into a reaction section and a separation section, as shown in Figure 9.

Any individual operation in the process - for example, fractionator C-2 - can be the system and everything else the surroundings. Finally, a portion of a single operation can be the system - for example, one tray in fractionator C If no heat is transferred across its boundaries, the system is said to be adiabatic or thermally isolated; and if neither work nor heat is transferred, the system is said to be totally isolated.
The most useful kind of energy transfer is work. For example, a rotating or reciprocating shaft at the boundary of a system causes shaft work. Less useful, but more common, is heat transfer, which occurs when the temperatures of the system and the surroundings differ.
If the system is at the higher temperature, it loses energy and the surroundings gain energy; and if the system is at the lower temperature, it gains energy and the surroundings lose energy. A number of devices are used in processes to transfer work between a system and its surroundings.
Pumps, compressors, blowers, and fans convert shaft work into fluid energy for the main purpose of increasing fluid pressure. Turbines and expanders take energy from a fluid, causing fluid pressure to decrease, and convert the energy to shaft work for use elsewhere.
As Industry 4. Design principles and goals[ edit ] There are four design principles in Industry 4. These principles support companies in identifying and implementing Industry 4.
Inter-connectivity allows operators to collect immense amounts of data and information from all points in the manufacturing process, thus aiding functionality and identifying key areas that can benefit from innovation and improvement. Second, the ability of cyber physical systems to physically support humans by conducting a range of tasks that are unpleasant, too exhausting, or unsafe for their human co-workers.
Decentralized decisions: The ability of cyber physical systems to make decisions on their own and to perform their tasks as autonomously as possible. Only in the case of exceptions, interferences, or conflicting goals, are tasks delegated to a higher level. Industry 4. It is marked by a transition from hand production methods to machines through the use of steam power and water power.
The implementation of new technologies took a long time, so the period which this refers to it is between and , or in Europe and the US. Its effects had consequences on textile manufacturing, which was first to adopt such changes, as well as iron industry, agriculture, and mining although it also had societal effects with an ever stronger middle class.
