Improve your choice of process control algorithms
This algorithm, when properly tuned, can greatly reduce the quantity of off-spec material made from a process upset. It can be the largest contributor to the benefits captured by improved process control.
Improve inline blending with advanced analyzers
Due to tough economic conditions, refiners are pressed to improve profitability. There is greater pressure to optimize gasoline and diesel blending. What are the options to improve processing of trans..
HP Reliability: Why users must update design contractors’ understanding
In early 2012, a rotating equipment engineer was involved in a machinery quality assessment (MQA).1 Located halfway around the globe, this engineer’s new job was to oversee the engineering, procu..
HP Integration Strategies: Could remanufactured control components place HPI plants at risk?
The hydrocarbon processing industry (HPI) must address a number of potentially catastrophic safety issues. One issue, in particular, is the growing use of remanufactured equipment and components from ..
HP Viewpoint: IT/OT integration—Is it safe?
Information technology (IT) includes conventional computers, operating systems, networking components and software platforms. All IT developments continue to increase in importance for industrial cont..
HP Viewpoint: Increase the visibility and reliability of all major plant assets
Turbomachinery, essential to refining and petrochemical operations, has significant impact on plant production, maintenance and energy consumption. One of the most effective ways to improve turbomachi..
Case history: Optimization of FCCU with multivariate statistical modeling
Process models and simulation methods can be used to simulate the fluidized-bed catalytic cracking unit (FCCU) process.a,b Likewise, kinetic or multivariate statistical models have been used. Rigorous..
Reduce salt corrosion rates with stronger base amines
When processing discounted crude oils, one of the primary challenges refiners face is under-salt corrosion in crude unit distillation overhead systems.
Mitigate fouling in crude unit overhead—Part 1
In a refinery crude distillation column, up to 40% of the total heat removal may be found in the tower overhead condenser. The quantity of duty available makes heat integration (HI) between the column..
Catalyst systems offer flexibility for hydroprocessing applications
Refinersa re strongly motivated to evaluate and select premier catalyst systems for the production of both diesel products from their hydrocracking and diesel treating units.
