Blender to upgrade Argentinian refinery
A Jiskoot Bunker Blender system is at the heart of an investment programme to upgrade operational capabilities at the Eg3 Refinery near Puerto Galvan, Argentina, by its new owner Petrobras Energia.

Blender controller enters distributed control mix
Three-term PID controller provides a cost-effective yet powerful and flexible solution for two-stream controlled rate or "wildstream" blending and analyser trim applications.
Gas sampling system suits demanding applications
Jiskoot's four-stream gas sampling system includes a human machine interface panel and a Profibus remote I/O module to minimise field cabling requirements.
The blender will produce bunker fuels on demand by using a Jiskoot Insight controller housed in a safe area control room near the marine fuels dock.
The operator simply enters the required volume and viscosity or selects a stored "recipe" on a touch sensitive screen.
This system automatically meters, blends, analyses, corrects and loads the exact viscosity mixture.
The system slows down gradually when the pre-established volume is almost complete before closing down and generating a dispatch report.
By avoiding the production of any leftover blended product requiring storage or disposal, the new equipment significantly reduces the cost in man hours, storage tanks and operation of the manual batch blending process that was previously used.
It also eliminates the possibility of human error and costly corrections.
The blender combines an 8in fuel oil line and a 4in diesel oil line, each having strainers, PD meters and actuated modulating butterfly control valves to produce the exact required proportion of the two components, which are then mixed by a pair of 10in static mixers.
It also analyses the mixture using a viscometer in a slipstream.
Temperature and viscosity information of the blend is fed back to a density converter and the Insight controller, which constantly adjusts the control valves to ensure that the blend is consistent despite changes in line pressures, temperatures or flow rates.
Finally, a sampler on the blender takes flow proportional samples of the blend for fiscal proof of the final product quality.
This operation is the first of several upgrades planned by Petrobras for the three refineries the company recently purchased in Argentina.
Jiskoot and its Argentina agent Meditecna cooperated on the system startup and Meditecna is providing local technical support from its offices in Buenos Aires.
