As per January 13,2018 Do as follow:
To remove a project, you have to be the owner of this project, or the administrator of gitlab. Otherwise you can only see "rename project" but no "remove project".
NOTE THAT: the creator project is NOT always the owner of the project. If the project is in a project-group, and the project-group is created by another one, then the owner is the creator of the project-group by default.
You can find the owner's name of the project in the page Settings -> Members.
As of October 2017:
1. In the list of your projects, click on the project you want to delete;
