The growing trends towards usage of gas in place of oil is posing a problem relating to compatibility of existing metals and material – mostly carbon based equipment- which are exposed to a different operational condition. Carbon steel which has proved to be good for most oil field application for over fifty years, has shown a variable behaviour at lower temperatures than at the normal refining conditions. That has led to the study of stainless steel as an alternative material of choice.

The need for LPG and LNG for industries such as polymers and petrochemicals necessitated new ways and means of containment, and transport of these as liquids, has became a challenge. Pure gases like air is one issue and hydrocarbons contaminated with water, oil and corrodants is another issue, which involve metal/ chemicals interactions at high pressures. Corrosion is consequential and failures follow. This course lists some of these obstacles in right material selection.

Objective

A new insight into metal /material behavior other than normal high temperature operation which is familiar to engineers/operators.

Audience

Process Engineers, Inspection Personnel, Mechanical Engineers, Material Selection Personnel, and those who handle material, and Corrosion Control Personnel.

Content

COURSE OUTLINE

Carbon steel, the old veteran

Metallurgy of Carbon steel, the most widely used metal in oil and gas industry equipmentsBasis for selection-physical, mechanical and metallurgical properties-Role of trace metals - effect of impurity and temperature-TTT diagram.

Pre- service defects during- fabrication- storing-transport –installation and commissioning - flaws - defects and failures

In service defects- simple environmental conditions -

Understanding corrosion- under ambient conditions and in presence of water

Why metals and materials fail?
Why different materials show different failure patterns?
The eight forms of material failure (corrosion)-Basic theory of corrosion
Understanding cause of failure- from case studies and photographs
Theory of corrosion made simple by experiments made by great people like Galvano, -Ohm’s law and Niels Bohr atomic theory.

Day 2

Gas processing environment

Types of Gas and oil resources- oil gas and water mixture and separation issues- Gas processing- phase issues and flow regimes- velocity and temperature factors in mixturescorrosion in TOL and bottom of line.

Types of environment in gas industry-aggressive-C02-H2S-amine, chloride, acid, sour water, Flue gas, caustic, ammonia, polythionic acids, olefins, aromatics-how they affect carbon steel at ambient condition.

Plant and machinery- pipes, storage vessels, reactors, pumps, compressors valves- heat exchangers-typical problems and failure patterns.

Day 3

Importance and principle of Cryogenics

What is cryogenics? - History of development-of liquefaction of air- the success and problems in containment transport and materials.

Introduction to Natural gas separation and purification- Cryogenic separation in production and associated impurities- solvents, gases, particulates - gas liquefaction and purification.

Day 4

Cryogenics and metallurgy

How carbon steel is affected by low temperature?

Introduction to Stainless steel – types and classification- how it is affected under wet gas condition-case study of failed components- stainless steel failure in production and transport of oil and gas mixture- failure under complex condition of H2S, CO2, Cl, O2, moisture in varying quantities.

Stainless steel in cryogenic application.
Stainless steel as cast components, lining and cladding material

What are Polymers? Their application for cryogenics

Storing and transport issues
Weldment failures
Coating issues
Cost versus reliability
Health and safety issues

Day 5

Material testing and failure analysis

Laboratory analysis by Atomic spectra
Particulate analysis by SEM, EDX
Acoustics for cracks and leaks
FEA for new and old equipment

NOTE: Pre & Post Tests will be conducted
Case Studies, Group Exercises, Group Discussions, Last Day Review &Assessments will be carried out.

Certificate

Define Management Consultancy & Training Certificate of course completion will be issued to all attendees.

Methodology

A highly interactive combination of lectures and discussion sessions will be managed to maximize the amount and quality of information and knowledge transfer. The sessions will start by raising the most relevant questions, and motivate everybody find the right answers. You will also be encouraged to raise your own questions and to share in the development of the right answers using your own analysis and experiences. Tests of multiple-choice type will be made available on daily basis to examine the effectiveness of delivering the course. All presentations are made in excellent colorful power point. Very useful Course Materials will be given.
