An International Journal of Computer Applications in Chemical Engineering

General
All contributions should conform to the Aims & Scope shown at the front of the journal. Only original papers will be considered. The receipt of a paper by the Editor is held to imply that submission for publication has been approved by all of the authors, that it has not previously been published in any language, that it is not under consideration for publication elsewhere, and that if accepted for publication it will not be published elsewhere without the written consent of the Editor.
The official language of the journal is English. Papers will be reviewed for proper English construction. Authors for whom English is a foreign language are recommended to have the manuscript thoroughly checked and corrected before submission.
The journal publishes full-length papers, reviews, short notes and letters to the Editors.
Full-length papers - should be complete and authoritative accounts of work, which has special significance and must be presented clearly and concisely.
Reviews - authors intending to offer a review article or a comparative survey are advised first to contact the journal Editor.
Short Notes are published in the journal for early communication of important results, extensions to recent publications, or brief descriptions of new applications, etcetera. Notes must be limited to 8 pages of double spaced typescript.
Letters to the Editors on subjects relevant to the readership will be considered for publication. Letters commenting on previously published articles will generally be sent to the authors of those articles to provide an opportunity for a response prior to publication. Letters should normally be limited to two pages of double spaced typescript.

Submission of Papers
Submission to this journal proceeds totally online, via the journal's EES homepage http://ees.elsevier.com/cace/. You will be guided stepwise through the creation and uploading of the various files. Once the uploading is done, our system automatically generates an electronic (PDF) proof, which is then used for reviewing. It is crucial that all graphical and tabular elements be placed within the text, so that the PDF is suitable for reviewing. All correspondence, including notification of the Editor's decision and requests for revisions, will be by e-mail. If you experience problems with the online submission system you can either contact the publisher at authorsupport@elsevier.com or the editorial office for further assistance.

Format of Typescript
All contributions should be in English and typed, double-spaced, with wide margins. The first page should contain the title, a list of authors' names, the affiliations and address(es) of the authors when the work was performed (new addresses should be given in a footnote). Email addresses may be included as a footnote.

Full length papers, Reviews and Short Notes should all include an Abstract and no more than six Keywords. The abstract should provide a clear statement of the objective of the study and its salient conclusions in no more than 150 words.
The body of the paper should start with an Introduction that is written for the general reader and not for the specialist. This introduction should describe the objectives and relevance of the work, significant prior work, as well as the major results and conclusions to be described subsequently.

The paper as a whole should provide the specialist with enough detail to permit him to evaluate and use the results. The manner of presentation of concepts, procedures, results and validation should include sufficient details to facilitate reproduction and checking. Thus multi-part papers will be considered if this is necessary for adequate exposition of important details. Alternatively, reference can be made to supporting reports available to the public. Authors are urged, where possible, to include in papers features such as flow charts, algorithms, input-output details and examples, with pertinent comparisons and critical evaluations.

The paper should terminate with a Conclusions section consisting of a clear and concise review of the final results and general conclusions. Significant figures, tables and program listings in the main text should be cited if appropriate.

Illustrations
Submitting your artwork in an electronic format helps us to produce your work to the best possible standards, ensuring accuracy, clarity and a high level of detail. Graphic files can be uploaded via the electronic submission service.

Regardless of the application used, when your electronic artwork is finalised, please "save as" or convert the images to one of the following formats (Note the resolution requirements for line drawings, halftones, and line/halftone combinations given below.):

EPS : Vector drawings. Embed the font or save the text as "graphics".
TIFF: Colour or greyscale photographs (halftones): always use a minimum of 300 dpi.
TIFF: Bitmapped line drawings: use a minimum of 1000 dpi.
TIFF: Combinations bitmapped line/half-tone (colour or greyscale): a minimum of 500 dpi is required.
DOC, XLS or PPT: If your electronic artwork is created in any of these Microsoft Office applications please supply "as is".

Please do not:
1. Supply embedded graphics in your word processor (spreadsheet, presentation) document;
2. Supply files that are optimised for screen use (like GIF, BMP, PICT, WPG); the resolution is too low;
3. Supply files that are too low in resolution;
4. Submit graphics that are disproportionately large for the content.

Colour illustrations
If, together with your accepted article, you submit usable colour figures then Elsevier will ensure, at no additional charge, that these figures will appear in colour on the web (e.g., ScienceDirect and other sites) regardless of whether or not these illustrations are reproduced in colour in the printed version.
Colour Illustrations can be printed in colour when they are judged by the Editor to be essential to the presentation. The publisher and the author will each bear part of the extra costs involved.
For colour reproduction in print, you will receive information regarding the costs from Elsevier after receipt of your accepted article. For further information on the preparation of electronic artwork, please see http://www.elsevier.com/artworkinstructions.

Please note: Because of technical complications which can arise by converting colour figures to 'grey scale' (for the printed version should you not opt for colour in print) please submit in addition usable black and white prints corresponding to all the colour illustrations.

Supplementary data
Elsevier now accepts electronic supplementary material to support and enhance your scientific research. Supplementary files offer the author additional possibilities to publish supporting applications, movies, animation sequences, high-resolution images, background datasets, sound clips and more. Supplementary files supplied will be published online alongside the electronic version of your article in Elsevier web products, including ScienceDirect: http://www.sciencedirect.com. In order to ensure that your submitted material is directly usable, please ensure that data is provided in one of our recommended file formats. For more detailed instructions please visit http://www.elsevier.com/artworkinstructions. Supplementary data files can be uploaded via the electronic submission services.

Nomenclature, units and symbols
Each paper should be consistent within itself as to abbreviations, symbols and units. Follow internationally accepted rules and conventions: use the international system of units (SI). If other quantities are mentioned, give their equivalent in SI. If there is extensive use of symbols a table of nomenclature should be provided at the end of the paper.
All mathematical symbols may be either handwritten or typewritten, but no ambiguities should arise. Greek letters and unusual symbols should be identified in the margin. Distinction should be made between capital and lower case letters; between the letter O and zero, between the letter 1, the number one and prime; between k and Kappa. A vector will be printed in bold face and to indicate this, the letter should be underscored with a single wavy line. The numbers identifying mathematical expressions should be placed in parentheses after the equation.

References
All citations in the text should refer to:
1. Single author: the author's name (without initials, unless there is ambiguity) and the year of publication;
2. Two authors: both authors' names and the year of publication;
3. Three or more authors: first author's name followed by 'et al.' and the year of publication. Citations may be made directly (or parenthetically). Groups of references should be listed first alphabetically, then chronologically. Examples: "as demonstrated (Allan, 1996a, 1996b, 1999; Allan and Jones, 1995). Kramer et al. (2000) have recently shown ...."

The list of references presented at the end of the article should be arranged first alphabetically and then further sorted chronologically if necessary. More than one reference from the same author(s) in the same year must be identified by the letters "a", "b", "c", etc., placed after the year of publication.
