Guide for Authors
The processes of reviewing, acceptance and publication of articles in the Gas Processing Journal (GPJ) are as follows:
1- The chief editor's opinion: after submitting your article, if the paper's file is complete, it is sent to the chief editor in order to determine the level and degree of its fitness with the journal's standards and finally selecting referees (usually 3) for a process of anonymous evaluation.
- If the chief editor's opinion is positive, the paper enters the next stage.
- If it is negative, a rejection letter is issued.
2- Looking through the paper to make sure of the observance of the journal's standards in terms of style and format. (If delivered in the wrong format and does not conform to the journal's policies, the paper will be returned to the sender for completion.)
3- Submission for evaluation; (if the file is complete and in full compliance with the journal's format, the paper will be sent to (usually 3) referees at the same time. Reviewing and Evaluating process: Single Blind).
4- Completion the results of the initial evaluation and revisions by the corresponding author.
- If the result is positive with 3 referees, the author gains access to "editing the paper" so that revisions will be made.
- If the result is positive with 2 referees and negative with 1 referee, the author gains access to "editing the paper" so that revisions will be made.
- If the result is negative with 2 referees, a rejection letter is issued.
5- Receiving the revised paper and sending it to one of the referees for final evaluation (if the paper is revised and re-submitted according to the journal's policies.)
6- Receiving the result of final evaluation and discuss it in the editorial board meeting for making a decision:
- If revisions are fully accepted and are approved in the final evaluation by the referee, the paper is discussed in the editorial board meeting, and granted that members accept the referee's opinion, an acceptance letter is issued.
- If revisions are partially accepted and are not approved in the final evaluation by the referee, the paper will be sent to the corresponding author for further revisions. Note that this process happens only one time, meaning if the paper is not approved by the referee after the second round, it is recommended in the editorial board meeting for rejection.
7- The paper is put in the publication waiting list
8- Publication (All papers, after final preparation and editing, will be sent to the corresponding author for a final review, so if there is a need for change, it will be done. In other words, an approval for the release of the paper is asked from the corresponding author).

Before You Begin
Submission declaration and verification
Submission of an article implies that the work described has not been published previously (except in the form of an abstract or as part of a published lecture or academic thesis), that it is not under consideration for publication elsewhere, that its publication is approved by all authors and tacitly or explicitly by the responsible authorities where the work was carried out, and that, if accepted, it will not be published elsewhere in the same form, in English or in any other language, including electronically without the written consent of the copyright-holder.
Language and language services
Please write your text in good English (American or British usage is accepted, but not a mixture of these).
Submission to this journal proceeds totally online and you will be guided stepwise through the creation and uploading of your files.
Online submission through journals' homepage
Please submit, with the manuscript, the names, addresses and e-mail addresses of three potential referees. Note that the editor retains the sole right to decide whether or not the suggested reviewers are used.
The following list will be useful during the final checking of an article prior to sending it to the journal for review. Please consult this Guide for Authors for further details of any item.
Ensure that the following items are present:
One author has been designated as the corresponding author with contact details:
• E-mail address
• Full postal address
All necessary files have been uploaded, and contain:
• All figure captions
• All tables (including title, description, footnotes)
• Manuscript has been 'spell-checked' and 'grammar-checked'
• References are in the correct format for this journal
• All references mentioned in the Reference list are cited in the text, and vice versa
• Permission has been obtained for use of copyrighted material from other sources (including the Web)
Subdivision - numbered sections
Divide your article into clearly defined and numbered sections. Subsections should be numbered 1.1 (then 1.1.1, 1.1.2, ...), 1.2, etc. (the abstract is not included in section numbering). Use this numbering also for internal cross-referencing: do not just refer to 'the text'. Any subsection may be given a brief heading. Each heading should appear on its own separate line.
State the objectives of the work and provide an adequate background, avoiding a detailed literature survey or a summary of the results.
Material and Methods
Provide sufficient detail to allow the work to be reproduced. Methods already published should be indicated by a reference: only relevant modifications should be described.
A Theory section should extend, not repeat, the background to the article already deal with in the Introduction and lay the foundation for further work. In contrast, a Calculation section represents a practical development from a theoretical basis.
Results should be clear and concise.
This should explore the significance of the results of the work, not repeat them. A combined Results and Discussion section is often appropriate. Avoid extensive citations and discussion of published literature.
The main conclusions of the study may be presented in a short Conclusions section, which may stand alone or form a subsection of a Discussion or Results and Discussion section.
If there is more than one appendix, they should be identified as A, B, etc. Formulae and equations in appendices should be given separate numbering: Eq. (A.1), Eq. (A.2), etc.; in a subsequent appendix, Eq. (B.1) and so on. Similarly for tables and figures: Table A.1; Fig. A.1, etc.
A concise and factual abstract is required. The abstract should state briefly the purpose of the research, the principal results and major conclusions. An abstract is often presented separately from the article, so it must be able to stand alone. For this reason, References should be avoided, but if essential, then cite the author(s) and year(s). Also, non-standard or uncommon abbreviations should be avoided, but if essential they must be defined at their first mention in the abstract itself.
Immediately after the abstract, provide a maximum of 6 keywords, using American spelling and avoiding general and plural terms and multiple concepts (avoid, for example, 'and', 'of'). Be sparing with abbreviations: only abbreviations firmly established in the field may be eligible. These keywords will be used for indexing purposes.
Define abbreviations that are not standard in this field in a footnote to be placed on the first page of the article. Such abbreviations that are unavoidable in the abstract must be defined at their first mention there, as well as in the footnote. Ensure consistency of abbreviations throughout the article.
Collate acknowledgements in a separate section at the end of the article before the references and do not, therefore, include them on the title page, as a footnote to the title or otherwise. List here those individuals who provided help during the research (e.g., providing language help, writing assistance or proof reading the article, etc.).
Nomenclature 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.
Present simple formulae in the line of normal text where possible and use the solidus (/) instead of a horizontal line for small fractional terms, e.g., X/Y. In principle, variables are to be presented in italics. Powers of e are often more conveniently denoted by exp. Number consecutively any equations that have to be displayed separately from the text (if referred to explicitly in the text).
Footnotes should be used sparingly. Number them consecutively throughout the article, using superscript Arabic numbers. Many wordprocessors build footnotes into the text, and this feature may be used. Should this not be the case, indicate the position of footnotes in the text and present the footnotes themselves separately at the end of the article. Do not include footnotes in the Reference list.
Indicate each footnote in a table with a superscript lowercase letter.
Ensure that each illustration has a caption. Supply captions separately, not attached to the figure. A caption should comprise a brief title (not on the figure itself) and a description of the illustration. Keep text in the illustrations themselves to a minimum but explain all symbols and abbreviations used.
Number tables consecutively in accordance with their appearance in the text. Place footnotes to tables below the table body and indicate them with superscript lowercase letters. Avoid vertical rules. Be sparing in the use of tables and ensure that the data presented in tables do not duplicate results described elsewhere in the article.
APA style requires both in-text citations and a reference list
The article will subsequently be published in electronically at the webpage.
