Syllabus

Introduction to Utility Systems

In the context of process plants, Utility Systems refer to the essential services and infrastructure required to support production and operations. These systems are designed to provide the necessary resources (e.g., water, steam, air, nitrogen, electricity etc.) and ensure the safe and efficient operation of the plant. These systems are responsible for supplying, controlling, and distributing various forms of energy, water, chemicals, and other necessary substances to the plant. The efficient functioning of these utility systems is critical to ensuring smooth operations, energy efficiency, and safety in industrial facilities. Utility systems are vital for maintaining smooth operations, supporting production processes, ensuring safety, and minimizing environmental impact. In this module, different types of Batch and Continuous Process plants are discussed. Utility systems are interconnected and have specific design schemes to ensure proper flow and control. Important utility schematics (e.g., RO-DM plant, Heavy Fuel Oil, Fuel Gas etc.) are covered in this module. Utility systems must adhere to strict codes and standards to ensure safety, reliability, and environmental compliance. Important codes, parameters, process documentation, and reference Engineering documents of L & T are covered in this module. Understanding the various types of utilities, their roles, and the relevant codes and standards is vital for engineers and plant operators to ensure smooth, reliable, and sustainable plant operations.

Design of Air System

The air system in a process plant is crucial for supplying compressed air to power tools, equipment, instrumentation, and other operational systems. The design of an air system involves ensuring that air is available at the required pressure, flow, and quality. It must be reliable, energy-efficient, and capable of meeting all process requirements while minimizing downtime and maintenance. In this module, introduction and usage as compressed air as utility, difference between plant air and instrument air, industry specification for various types of compressed air are discussed. We also explore the types of air compressors, and how to size them based on specific requirements. In depth understanding of Instrument air supply used for controlling pneumatic instruments, valves, and other process equipment in industrial facilities such as oil refineries, chemical plants, and power plants are discussed. Types of dryers that are used to remove moisture from compressed air are covered. Aspects on the Material of Construction (MOC) is crucial for air system which matters the durability, corrosion resistance and must adhere strict Industry standards are covered. Also, procurement strategy and Engineering Documents required as inputs for design using reference L&T project documents are covered in detailed.

Design of Nitrogen System

A Nitrogen System is used in various process industries (oil & gas, petrochemical, pharmaceutical, food, etc.) for purging, blanketing, inert agent, and packaging applications. The system can be designed to generate nitrogen on-site or use nitrogen from cylinders or bulk storage tanks. A nitrogen system is designed based on purity, flow rate, pressure, and application requirements. In this module application of nitrogen, codes & standards for nitrogen systems such as ASME B31.3, NFPA 55, etc., storage & transportation standards for pressure vessel design for Nitrogen tanks (e.g., ASME Section VIII, EN 13458, etc.,) liquid nitrogen transportation regulations, cryogenic storage tank for liquid nitrogen and safety practices for liquid nitrogen handling are discussed. The types of nitrogen onsite production methods such as Pressure Swing Adsorption (PSA), cryogenic, and membrane plant are covered. Catering to nitrogen in process plants, and the difference between storage and on-site generation, redundancy, and backup for uninterrupted nitrogen availability are discussed in detail. Also, the overall & cost comparison of three nitrogen-generating technologies, nitrogen process control, Material of Construction (MOC) & procurement strategy, as well as engineering documents required as input for the design using L&T project documents are covered in this module.

Design of Water System - Part I

Water is a critical utility in Chemical Process Industries (CPI), serving various functions such as process operations, cooling, steam generation, firefighting, and potable use. Efficient water management ensures process efficiency, safety, and compliance with environmental regulations. In this module, we will delve into the various sources of water in CPI, and the types of water systems used in CPI for example raw water, potable, cooling, and fire water systems. The module also covers the water composition and its interpretation based on physical, chemical, and biological parameters. This module covers raw water and its sources such as groundwater, municipality supply or desalinated seawater, their equipment involved such as pumps and intake screens, settling tanks, chemical dosing systems, etc., MOC (Material of Construction) for Raw Water System for its piping, tanks and filters, chemicals used in their treatment such as coagulant, disinfectant, and pH. Potable water systems have their quality as per WHO guidelines, EPA & BIS standards, their uses in CPI such as drinking, sanitation, and emergency eye wash stations, the Material of Construction (MOC) in piping, storage tanks, and various chemicals used in the treatment. Fire water systems and quality standards such as 1S 15105, their equipment involved such as fire pumps, fire hydrants, sprinkler systems, storage tanks, and MOC for piping, pumps, and valves. Cooling water quality interpretation, types of equipment used such as cooling towers, and heat exchangers, etc. their MOC for types of equipment, and chemicals for inhibiting scaling, corrosion, etc. are covered comprehensively in this module.

Design of Water System - Part II

Water is an essential utility in CPI, requiring proper treatment, storage, and distribution. Different types of water systems have specific quality requirements and equipment to maintain efficiency and safety. Proper MOC selection and chemical treatment ensure reliable performance and longevity of water systems in industrial applications. In this second part design of water systems, sea water interpretation, key parameters and its quality, equipment used in sea water systems, various desalination methods of sea water, their material of construction and treatment chemicals used are covered. Secondly, boiler feed water systems their uses in CPI, their interpretation of boiler feed water quality, types of equipment’s used in treatment of boiler feed water system, material of construction and handling chemicals used are discussed.
