Types of Plant Layout – It begins with the design of the factory building and goes up to the location and movement of a work table. After discussing Plant Layout, this article explains their types. The types of Plant Layout are the main three; process, product, and stationary layout, but in the modern world two extra types; combination and Fixed position Layout.

An example of a non-circular cross-section in heat exchanger applications is an annulus, which is the region between two circular pipes. Another is a rectangular duct, used in HVAC (Heating,, and Air-Conditioning) applications. Ventilation Less common are ducts of triangular or ellipticalcross-sections, but they are used on occasion .

An ethylene production plant was designed to meet a product speci cation of 700 metric tons per day. To do so, 140,010 lb/hr of butane is fed to the plant, and of ethane is recycled at a rate of 8,174 lb/hr. This plant process includes: a furnace (to crack the hydrocarbon
(section 200), and the catalytic reactor (section 300). Relevant sample calculations, process flow diagrams, costing, and other forms of analysis are included for each section. Ultimately, the process engineering team was successful at designing a carbon neutral modular production plant capable of producing 50 metric tons per day.
Plant wide control involves linking several sub models of the process, under a single main controller/optimizer. The intermediate variable that connects the sub controllers is typically the feed flow from the upstream sub controller. The overall main controller optimizes the whole plant taking into account of constraints across the whole plant.
It might be necessary to calculate, for example, the surface area of the cross-section of a canal or the surface area of a farm. This Section will discuss the calculation of some of the most common surface areas: the triangle, the square, the rectangle, the rhombus, the parallelogram, the trapezium and the circle (see Fig. 1a).

Gas-Turbine Cogeneration Process. When generating energy on-site, many plants use a gas-turbine cogeneration process. The thermal efficiency of a gas-turbine process is in the range of 70-80% while conventional power stations, such as coal-fired processes, have a 30-40% efficiency.
