Refinery crude units often process variety of feedstocks. If properties of the feed entering the crude unit are not precisely known, it is difficult to predict how changes in the tower operating conditions will affect properties of the products. Similarly, if on-line analyzers are not available, it...

There are various NGL(Natural Gas Liquid) recovery units in North America which are designed to recover olefins and NGL components like ethane, propane, butanes etc by processing the off-gas from various sources like the refinery or Petrochemicals Complex. There is an increased demand to install...

The amount of heat recovery achieved in the pre-heat train used ahead of the fired heater feeding a crude oil distillation unit does not just affect fuel efficiency of the process by controlling the heating that must be undertaken in the fired heater. It can also affect the fouling encountered...

Classical MPC has been leveraged to improve control on a nonlinear unsteady-state system, batch alcohol fermentation. The controller uses a hybrid model with fundamental reaction equations along with empirical process data-based modeling. More than thirty lines of batch quality control have been...

Control of feed pH control is an important task in chemical industries, wastewater treatment, polymerization reactions, fatty acid production and biochemical processes. However, this is a challenging problem due to (i) presence of large and varying time delays and (ii) complex time varying...

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 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...

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...
