'''Wind Point Lighthouse''' is an active aid to navigation located at the north end of [[Racine, Wisconsin|Racine]] Harbor in the [[U.S. state]] of [[Wisconsin]]. Designed by [[Orlando Poe|Orlando Metcalfe Poe,]] it was constructed in 1880.

It is one of the oldest active [[lighthouse]]s on the [[Great Lakes]]. The beacon, originally powered by third order [[fresnel lens]], was replaced by a DCB-24R Aerobeacon in 1964. The light can be seen for 19 miles.

'''Chemical engineering''' is the branch of [[chemistry]] and [[engineering]] that deals with the application of [[physical science]] (e.g. [[chemistry]] and [[physics]]), with [[mathematics]], to the process of converting raw [[material]]s or [[chemical]]s into more useful or valuable forms. As well as producing useful materials, chemical engineering is also concerned with pioneering valuable new materials and techniques; an important form of [[research and development]]. A person employed in this field is called a [[chemical engineer]].

The lighthouse stands 112 feet tall. It is on the [[National Register of Historic Places]] (Reference #84003780).

Chemical engineering largely involves the design and maintenance of chemical processes for large-scale manufacture. Chemical engineers in this branch are usually employed under the title of '''process engineer'''. The development of the large-scale processes characteristic of industrialized economies is a feat of chemical engineering, not chemistry. Indeed, chemical engineers are responsible for the availability of the modern high-quality materials that are essential for running an industrial economy.

Located on Lighthouse Road, next to the Shoop Park golf course, it is set on a sprawling lawn overlooking Racine Harbor. A signal house (horns removed) remains on the grounds as well as a garage, 2 storage buildings and an oil house. The Wind Point Police maintain offices in the attached building.

Following is an example that illustrates the engineering aspect of chemical engineering:

:"The difference between chemical engineering and [[chemistry]] can be illustrated by considering the example of producing orange juice. A chemist working in the laboratory investigates and discovers a multitude of pathways to extract the juices of an orange. The simplest mechanism found is to cut the orange in half and squeeze the orange using a manual juicer. A more complicated approach that is found is to peel and then crush the orange and collect the juice.

:"A company then commissions a chemical engineer to design a plant to manufacture several thousand tons of orange juice per year. The chemical engineer investigates all the available methods for making orange juice and evaluates them according to their economic viability. Even though the manual juicing method is simple, it is not economical to employ thousands of people to manually juice oranges. Thus, another -- cheaper -- method is used (possibly the 'peel and crush' technique). The easiest method of manufacture on a laboratory bench will not necessarily be the most economical method for a manufacturing plant."

A prototypic example of the development of chemical engineering as a science is the [[Haber-Bosch process]].

The tower is 108 feet tall with a 111 foot focal plane.

== Overview ==

Chemical engineers are aiming for the most economical process. This means that the entire production chain must be planned and controlled for costs. A chemical engineer can both simplify and complicate "showcase" reactions for an economic advantage. Using a higher pressure or temperature makes several reactions easier; ammonia, for example, is simply produced from its component elements in a high-pressure reactor. On the other hand, reactions with a low yield can be recycled continuously, which would be complex, arduous work if done by hand in the laboratory. It is not unusual to build 6-step, or even 12-step evaporators to reuse the vaporization energy for an economic advantage. In contrast, laboratory chemists evaporate samples in a single step.

The individual processes used by chemical engineers (eg. [[distillation]] or [[filtration]]) are called [[unit operation]]s and consist of [[chemical reaction]], [[mass transfer|mass-]], [[heat transfer|heat-]] and [[fluid dynamics|momentum-]] transfer operations. Unit operations are grouped together in various configurations for the purpose of [[chemical synthesis]] and/or [[separation of mixture|chemical separation]]. Some processes are a combination of intertwined transport and separation unit operations, (e.g. [[reactive distillation]]).

Three primary physical laws underlying chemical engineering design are [[conservation of mass]], [[Momentum|conservation of momentum]] and [[conservation of energy]]. The movement of mass and energy around a chemical process are evaluated using [[mass balance]]s and [[energy balance]]s which apply these laws to whole plants, unit operations or discrete parts of equipment. In doing so, chemical engineers use principles of [[thermodynamics]], [[reaction kinetics]] and [[transport phenomena]]. The task of performing these balances is now aided by process simulators, which are complex software models (see [[List of Chemical Process Simulators]]) that can solve mass and energy balances and usually have built-in modules to simulate a variety of common unit operations.

== Modern chemical engineering ==

The modern discipline of chemical engineering encompasses much more than just process engineering. Chemical engineers are now engaged in the development and production of a diverse range of products, as well as in commodity and specialty [[chemical]]s. These products include high performance materials needed for [[aerospace]], [[automotive engineering|automotive]], [[biomedical engineering|biomedical]], [[electronics|electronic]], [[environmental engineering|environmental]] and space and [[military]] applications. Examples include ultra-strong fibers, [[Cloth|fabrics]], [[adhesives]] and composites for vehicles, [[Biocompatibility|bio-compatible materials]] for implants and [[prosthetics]], [[gel]]s for medical applications, [[pharmaceuticals]], and films with special [[dielectric]], optical or [[spectroscopy|spectroscopic]] properties for opto-electronic devices. Additionally, chemical engineering is often intertwined with [[biology]] and [[biomedical engineering]]. Many chemical engineers work on biological projects such as understanding biopolymers ([[proteins]]) and [[human genome project|mapping the human genome]].
