Description
Pumps have been the heart of any plant as they are the main equipment used to guarantee the required process flow or pressure. Pumps are used extensively in oil and gas, chemical and petrochemical industries to pump different fluid types at various pressures and temperatures.Without a pump or if there is a problem in the pump operation, this can cause a huge process disturbance, and in some cases, this may lead to process shutdown.Sizing the pumps and their suction and discharge systems is one of the major carried out activities in process design. This course will not just explain the theory of operation of a pump against the process. We will see live examples where we shall calculate main pump requirements with respect to the net positive suction head, differential head, and hydraulic power.This will be through excel sheets that will be provided in the course to teach you how to calculate these parameters. Calculation sheets will be available to you throughout the course.In this course, We shall see how the pump curve works and how to plot it against the system curve. We will see how the pump and process system interact with each other and how the pump responds and interacts with process changes or disturbances. We shall examine the pump curve for both centrifugal and positive displacement pumps and see how each of them interacts with the discharge system differently.We shall see different control methods to make sure we are on the required pump operating point. We shall also see different pump configurations and how to operate the pumps in series and in parallel and how this is reflected on pump curves.
