Reducing the Load on Cooling Towers through Revamping of Individual Coolers

Mar 14, 2011
Graham T. Polley
The engineering of cooling water systems involves a consideration of both hydraulic and thermal behaviour. Unfortunately this is often ignored. For instance when engineers seek to reduce the thermal load on cooling towers they will often opt for increased heat recovery (via improved heat...

New Continuous Coking Process

Mar 14, 2011
Douglas W. Sullivan
NEW CONTINUOUS COKING PROCESS A new coking process can accept resid feed from the conventional resid heater in a coking plant and continuously discharge vapor and dry petroleum coke particles. The process promotes a rapid recovery of volatiles from the resid enabling recovery of more volatiles. It...

Steam Utility Systems Are Not "Business as Usual" for Chemical Process Simulators

Mar 14, 2011
Jonathan Currie
The operating costs of a typical refinery utility system are so significant that small operational improvements can result in large annual savings. This paper introduces a new utility modelling package designed for PETRONAS to allow in-house modelling and optimization of their refinery and...

Processing Heavy Crudes In Existing Refineries

Mar 13, 2011
Kevin Turini
Increasing amounts of heavy crudes are being produced, particularly in Canada and South America. The discount prices for these crudes, relative to light sweet crudes, make them attractive for refiners that can process them, particularly if they have a geographic advantage relative to the crude...

Nathan Stokes
New advancements in multivariable pressure transmitter technology allow you to improve your flow measurement practices. By better understanding these advancements, you will be better able to quantify and optimize installed performance, select the right combination of compensation for a specific...

Variability, Inventory Uncertainty and Supply Chains

Mar 22, 2010
Tony Cooper
This session will develop a fundamental understanding of how cycle time variation in stages of a supply chain propagates into measures of overall cycle time. Application can be seen in supply chains and inside plants with batch processes. While the sources of variation are symmetrical and can be...
