The overview of the problems of the transportation of oil in the pipeline
network depending on the quality of oil and its content

Assiya

Rationale

The purpose of this paper is to overview and to analyze the dependence of the oil
content on its transportation efficiency and to find out possible solutions towards
arising problems.


Introduction

The characterisation of different types of oil is unique
and each crude oil has its
unique molecular and chemical content. The percentage of one or another
compound defines the cost and quality of oil, its transportability in different
conditions.

In recent years with the increasing demand of energy the consum
ption of heavy oil
has been grown. However the transportation of these types of

oil is
difficult, as for
example, high wax content in
heavy
crude oil leads to pressure drops and formation
of crystals that result in shutdowns in pipeline system and other pr
oblems.

The aim of this paper is to present and analyze such problems and evaluate existing
solutions in terms of its availability and efficiency.

Main body

1.

Background information, basic terms of fluid mechanics in pipeline network,
oil as

a non Newton fluid;

2.

Transportation problems due to rheological characteristics of oil (the
phenomena of hydrate formation in pipeline network)

3.

Description

and
analyze of applying methodic, comparison and evaluation.

a.

Hot oil pipelines
, examples
;


b.

Mixing o
f the different types of oil;

c.

Comparatively new direction: application of p
olymeric additives

that
can regulate rheological characteristics of oil.

Conclusion

Evaluation of existing methods
