on many factors, the most important of which are discussed below.
In general, the layout of the plot plan can take one of two basic configurations: the grade-level, horizontal,
in-line arrangement and the structure-mounted vertical arrangement [5]. The grade-level, horizontal, in-
line arrangement will be used for the DME facility. In this arrangement, the process equipment units are
aligned on either side of a pipe rack that runs through the middle of the process unit. The purpose of the
pipe rack is to carry piping for utilities, product, and feed to and from the process unit. Equipment is
located on either side of the pipe rack, which allows for easy access. In addition, vertical mounting of
equipment is usually limited to a single level. This arrangement generally requires a larger “footprint”
and, hence, more land than does the structure-mounted vertical arrangement. The general arrangement for
these layout types is shown in Figure 1.9.
