1. Computer Applications in Chemical Engineering

Computers are used nowadays in many cases in all fields including chemical engineering. Computershave also revolutionized the way chemical engineers design and analyze processes, whether designing

large units to make polyethylene or small microreactors to detect biological agents. Computer programs

can now solve difficult problems in a fraction of the time it used to take and also do the numerical

calculations for you. And here are some computer applications in chemical engineering:

2. Identify Common Software Used in Chemical Engineering

Software Purpose

AspenTech HYSYS Integrated package from Hyprotech that covers all process

simulation and real-time applications. Flowsheet based dynamic and

steady state process modeling.

Process Simulation Software A model-based representation ofchemical, physical, biological, and

other technical processes and unit operations in software. Describes

processes in flow diagrams where unit operations are positioned and

connected by product or educt streams.

ChemCADAn integrated suite of intuitive chemical process engineering

software. It has the power and tremendous range of capabilities to

meet an engineer's chemical process simulation needs, from day-to-

day challenges to large, multifaceted projects.

MATLAB A high-performance language for technical computing. It integrates

computation, visualization, and programming in an easy-to-use

environment where problems and solutions are expressed in familiarmathematical notation.

3. Overview of Word Processing Software

Many single users, offices, businesses and organizations use computers to create, edit and print written

documents. For this reason word processing software are sought. Word processing software is used to

compose, edit, format and print written documents with high quality, in a timely fashion. Word

processors are also known as document preparation systems, which happen to be computer application

software.

The basic types of word processors (before the time of computers) were type writers and electrical typewriters. These machines gave very limited range when it came to composing and editing a document. It

was not possible to change fonts or create different types of bullets. Typing errors needed to be zero,

for if they happened, the finish of the document will not be up to standard.

Modern word processing programs, however, include features to customize the style of the text, change

the page formatting, and may be able to add headers, footers, and page numbers to each page.

Word processing applications are among the most widely used software programs available. Different

word processing applications are used with the various operating systems and platforms, but they all

provide roughly the same functionality. Word processing applications are used within personal and

business communications, to create many different types of document. Any word processor is generallyexpected to offer a few key features.

Text

One of the key elements in a word processing application is the ability to enter and save text in digital

files. However, a defining characteristic of a word processing application is also that it offers text

processing functions beyond those of a basic text editing program. Rather than simply saving text in

".txt" files, word processors are able to format text in various ways, saving it using extensions such as

".doc" in Microsoft Word, ".odt" in Open Office and ".pages" in the Mac iWork office suite.

Formatting

Word processors provide the ability to format documents in a number of ways. Text appearance and

document layout can be controlled through the user interface. Buttons and menu items allow users to

control fonts, text size, text style, decoration, margins and line height, among many other features.

Footnotes, headers, footers and page numbers are commonly used elements provided as standard.

Templates

The most popular word processing applications provide a number of set templates for various specific

purposes. When such templates are selected, users can enter their text within a set layout including

styles that are appropriate to the template context.

Tools

Word processors typically provide a range of processing and organizational tools designed for use by

individuals and companies. Spell-check facilities allow users to identify and correct spelling errors within

their chosen language. Organizational tools include mail merging, in which a data source can be used to

send the same letter to multiple addresses using templates.

Inclusion of Other MediaWord processing documents can contain media imported from external sources. This can include images

imported from the user's computer or over a network. Data can also be imported, such as structured

table data from an external spreadsheet document.

Samples of Word Processing Software

Microsoft Word

One of the most well-known and widely used word processing applications on the market is Microsoft

Word. Microsoft Corp. first released this program to the market in 1989, and since then there have been

a number of upgrades to the software. Word can be purchased as part of the Microsoft Office suite of

programs, which include Excel, PowerPoint, Outlook and Publisher. Word can be used to format text andbuild layout documents.

WordPerfect

WordPerfect is a word processing application from Corel Corp. WordPerfect was popular in the early

1990s. It is best for writing simple essays and articles. Though it isn't used as much today, WordPerfect is

compatible with Microsoft Word, meaning that you can open and edit WordPerfect files in the Word

program, then save them as WordPerfect files again. WordPerfect also can be used for formatting and

laying out documents.

Lotus Word Pro

If you use Lotus Notes or Lotus 1-2-3--common in corporate environments--Lotus Word Pro is an ideal

program for your word processing needs. This program works in concert with Lotus applications to allow

you to create and distribute formatted text documents. It is produced and distributed by IBM Corp.

Lotus Word Pro is also compatible with Microsoft Word and ideal for writing reports, memos and

proposals.

iWork Pages

Pages is a word processing program offered by Apple Incorporated. It is a part of Apple's iWork suite of

programs. Pages allows you to perform basic word processing functions--writing and formatting--as well

as more complex graphical layout actions. You can open and save Pages files in Microsoft Word.

Others

There are dozens of word processors on the market. Other lesser-known word processors include

OpenOffice Writer, Adobe InCopy, AbiWord, Microsoft Works and Scrivener. A growing number of

online word processors are available and include Google Docs and Microsoft Office Web Apps.
