Delegates will receive a thorough understanding of the design, building, control, and operation of screw compressors, which are often used in the oil, gas, and other process industries, throughout this 5-day course.

The course covers the fundamentals of compressor functioning and explains how the design of the compressor may be modified to accommodate various requirements due to a combination of physical limitations on the gas being processed and the materials used in the compressor's construction.

Course Objectives:

This course explores the construction and configuration of the screw gas compressor in some detail:

· Classification of compressor units (types)

· The effect of the process system on compressor performance

· Screw compressor performance - the curve, concepts and relationships

· Screw compressor mechanical design - rotor, seals, …..etc.

· basic understanding of the application, sizing,

· Operation and maintenance of screw compressors.

· Describe the purpose of a dry Seal,

· Identify the parts of a dry Seal,

· Describe dry Seal classifications,

· Describe dry Seal materials of construction,

· Describe dry Seal operation, identify Seal environmental controls, describe Seal design history, and troubleshoot some basic Seal failures.

Who Should Attend?

To maximize the benefits of the course, delegates should be prepared to actively participate in the course and bring examples of standard work plans, a list of plant performance metrics, the work priority system in-place, and any other planning or scheduling material they would like to review and discuss.
