Control System Techniques in Equipment Design and Operations

In-Company Training
A high level of automation and sophistication is required to control process parameters and detect equipment faults in today’s petrochemical plants. Join control system expert A.S. Rangwala and learn automatic control theory methods that enhance efficiency and provide operational safety by ensuring process parameters do not exceed design capability.

Fuels Blending Technology and Management

In-Company Training
In today’s highly competitive marketplace, the economic and efficient management of blending operations and automation can give you that critical edge over competitors. Join refinery offsite automation expert Suresh S. Agrawal for an overview of the principles of operation and decision-making involved in the management, operation, control, optimization and scheduling of gasoline, diesel, fuel oil products and crude oil.

Integrated Process Synthesis

In-Company Training
As a chemical engineer, before you can make proposed process alterations you must consider the potential investment return. Yet, typically this involves detailed simulations and design work. Join process synthesis and integration experts Diane Hildebrandt and Bilal Patel and learn novel design and analysis techniques you can implement early on to avoid costly revisions to processes while reducing material and energy consumption and carbon dioxide emissions.

Advanced Control of Multiple Sulfur Recovery Units

Apr 2, 2012
Darwin Logerot
Sulfur Recovery in a Refinery entails collecting sour vent gases (containing H2S) from a number of sources, including Hydrotreaters, Hydrocrackers, Crude Units, and others, then converting the H2S to a more useable form such as sulfuric acid or elemental sulfur. The feed rates and compositions to...

Advanced Process Control: Beyond Single Loop Control

June, 2010
This book fills the gap between basic control configurations (Practical Process Control) and model predictive control (MPC). For those loops whose performance has a direct impact on plant economics or product quality, going beyond simple feedback or cascade can improve control performance, or...
