CHEMICAL PROCESSES AND PLANTS
Starting from a vaguely defined problem statement such as a customer need or a set of experimental results, engineers can develop an understanding of the important underlying physical science relevant to the problem and use this understanding to create a plan of action and set of detailed specifications which, if implemented, will lead to apredicted financial outcome (1).
CHEMICAL PROCESSES AND PLANTS A chemical process is a set of logically arranged stages that allows transform raw materials in products that accomplish the specifications defined by the customer needs, needs integrating energy and valorizing effluents effluents. From the customer point of view, the molecule is not p , important, because customer buys a set ofproperties which make possible an use or application. Then, the real goal of chemical processes is to produce the change from the properties of raw materials to the products ones, adding aggregated value.
CHEMICAL PROCESSES AND PLANTS A process plant is the place where a chemical process is made and includes: The land and the vicinity Process, utilities and industrial safety equipment and piping,piping including laboratories laboratories. Electrical, control, instrumentation and communication , , equipments and interconnection facilities. Buildings, structures, supports, offices and any other B ildi ffi d h civil work. Personal

A chemical process plant (1, http://www.desmetballestraoleo.com/)CHEMICAL PRODUCT A chemical product may consist of an individual chemical, but more frequently it will be a mixture of chemicals with a set formulation and often a set microstructure (2) with some functional properties (2), which make possible an use or application.
These chemical products may be described as formulated products (2), in contrast with assembled products.

LIFE CYCLE OF A PROCESS PLANT Design is the morecreative of the engineering activities: it is the essence of engineering and the activity which differences the engineering from a scientist (2). According to RAE (http://buscon rae es/draeI/) design is to (http://buscon.rae.es/draeI/), conceive an object or original work with the objective of produce it in series series. The designer begins with a specific objective or customer g g p j need in mindand, by developing and evaluating possible designs, arrives at the best way of achieving that objectivebe it a better chair a new bridge or for the chemical chair, bridge, engineer, a new chemical product or production process (1).

LIFE CYCLE OF A PROCESS PLANT Product design
The object of product design is to specify a small set offormulations likely to meet product requirements, prior to experimentation, and which can be confirmed or p , redefined through experimentation (2)
Determine the composition of chemical mixtures that provide desired properties and create configured industrial and consumer products (3)
