An Instant Improvement to Distillation

Hydrocarbon Magazine, 2011

A small group of engineers at LyondellBasell generate instant energy savings on a distillation column. This article was published in Hydrocarbon Processing magazine. Find out how PlantTriage pointed this team directly to the major problem on this column, driving steam costs down within just a few hours.

Problem: Crude Unit Cycling

A small refinery was suffering from stability problems in the crude unit. Persistent cycling upsets were constraining production capacity. A Model Predictive Control (MPC) System was unable to solve the problem.

Solution

Using ExperTune's software, the source of the cycling was quickly traced to a single sticky control valve. Repairing the valve completely eliminated cycling on the unit. The total cost of the solution was less than $100,000.

Results

Elimination of the cycling stabilized the unit, reduced energy demand, and allowed for an incremental production increase. The total effect was more than $330,000 per year in increased profit.

 Off-Shore Platform Commissioning

Overview

Offshore Oil Processing. An offshore oil field is being developed using a Floating Production Storage and Offloading vessel (FPSO). This facility is a ship-shaped vessel with integrated oil storage.

The Challenge:

A new 900 foot long ship with oil separators on the ship. The ship hooks up to the oil well, processes and offloads fuel to a tanker. This is a 3 billion dollar project that produces 100,000 barrels per day of oil. It is important to get the most out of this capital investment by getting the ship up and running quickly and out to sea. They did not want tuning to be a bottleneck in getting the ship started up. There is $3 million dollars a day in revenue from this ship.

The Solution:

Petro Canada purchased PID Loop Optimizer software and trained 2 crews in its use.

The Result:

Our software conservatively saved at least 1/2 day of start-up time. It probably saved 3 days of start-up time. 4 hours of start-up time on this vessel is worth at least $500,000.

 APC Project on a FCC

Overview

A large refining company installed PlantTriage as a pre-cursor to an Advanced process Control project on a Fluidized-Bed Catalytic Cracking Unit.

PlantTriage identifies interactions

The Challenge:

Difficult interactions and oscillations around the FCC unit made it difficult to develop APC models. Without process stability, reactor setpoints must be lowered to maintain stability.

The Solution:

PlantTriage was installed to monitor the system and determine the sources of interaction. With the interactions identified and source of variation eliminated, Reactor setpoints were raised.

The Result:

With reactor setpoints raised, there was a direct savings of over $300,000 annually. In addition, the resulting process stability made it simpler to develop the APC project.
