Set refinery profitability goals

Johnson, A., Johnson, E., Graham Corp.; Lieberman, N., Process Improvement Engineering

While the ultimate purpose of operating a refinery is to produce gasoline, diesel or asphalt, key objectives include improving return on investment (ROI), net profitability and cash flow.

Case study for a high-performing refinery loss control program

Valentine, J., Emerson Automation Solutions; Videla, R., YPF

Most refineries have some sort of mass balance and loss control program in place for accounting, planning and scheduling, as well as for financial and operational evaluation purposes.

Coke drum and blowdown system overpressure protection design—Part 2

Geronimo, G. DI, ExxonMobil Rotterdam refinery; Ceary, P. J., Markham, N., ExxonMobil Research and Engineering Co.; Groenendijk, S., Moreno, Y., Fluor

The blowdown (BD) system in delayed coking units (DCUs) receives waste streams generated during the coke drum (CD) decoking process to recover valuable hydrocarbons and water.

Innovations

Rhodes, Mike, Hydrocarbon Processing Staff

Engineers tasked with finding a green solution to waste gas emissions from hydrocarbon storage tanks during loading and unloading operations will find that the ST100 series thermal flowmeter from Fluid Components International (FCI) supports tank vapor recovery systems, which help reduce greenhouse gas emissions.

Cut costs and save time servicing valves during refinery turnarounds

Dalal, N., Emerson Automation Solutions

Most refineries perform turnaround activities every 3 yr–5 yr to maintain and upgrade plant assets and equipment.

Stable thermosiphon reboiler operation: With or without a valve in the inlet piping?

Kister, H. Z., Fluor Daniel; Van Doorn, E., Fluor

A reboiler provides the necessary heat duty for the separation in a distillation tower.

Designed for hazardous, wet or corrosive locations, such as oil refineries and chemical plants, the Appleton PlexPower motor starter provides electrical apparatus protection combined with the convenience and savings of off-the-shelf components.

Understand API and ASME standards to prevent oversizing PSVs

Taylor, B., Anvil Corp.

If you have ever sized or selected a pressure safety relief valve (PSV) using vendor sizing programs or hand calculations, you have probably run into a strange anomaly.

Improve refinery production and efficiency with asset monitoring

Donnangelo, M., Emerson Automation Solutions

The sheer volume of equipment in a refinery—from vessels, columns, huge structures and mazes of pipes to pumps, valves, controllers and instruments—is staggering.
