Invensys implementing Foxboro control systems for long-term modernization project at Tripoliven C.A. chemical plants in Venezuela

Tripoliven to support product quality control and plant data access objectives using economical Foxboro A2 DCS with Wonderware Web portal


Invensys Process Systems has been selected by Tripoliven C.A. of Venezuela to implement upgraded replacement controls for all four plants in their manufacturing complex. Tripoliven manufactures phosphoric acid, sodium tripolyphosphate and related products at the Moron Industrial Area in Carabobo Estate, Venezuela.

The first phase of the Tripoliven modernization is in the phosphoric acid plant, to achieve more accurate control and maintain the company’s stringent product quality specifications. More than 400 I/O points from across the process will be monitored and controlled by a Foxboro A2 (www.foxboro.com) distributed control system (DCS). Plant data acquisition and multi-loop control will be performed by Model 2500 control modules. A control network employing PROFIBUS DVP1 protocol will connect the I/O and control modules together and with a T940X process supervisory controller.

Tripoliven expects to benefit from easier access to operational and performance data through the use of Wonderware (www.wonderware.com) InTouch Human Machine Interface (HMI) software from Invensys. This software, which runs on Foxboro A2 control system workstations, will permit more user-friendly visualization, operation and configuration of the phosphoric acid plant’s controls.

In addition, Tripoliven will use the Suite Voyager Web portal from Wonderware. Incorporating the latest Web technologies, Suite Voyager provides a protected, secure portal, through which production information from the process database can be accessed by authorized employees from local or remote locations.
Invensys Venezuela is providing services to assist Tripoliven in the installation of the first phase of chemical plant control system modernization. The upgraded automation of the four Tripoliven plants is expected to be completed at the end of 2006.
The Foxboro A2 control system provides the capabilities of a distributed control system (DCS) at costs comparable with less functional PLC-based control systems. It offers application flexibility, ranging from basic self contained control to multi-layered systems, such as Tripoliven is using, with supervisory control and a variety of high-function operations viewing environments using Wonderware HMI software.
