Tyco Flow Control at first Bioethanol
plant in UK
Tyco Flow Control will supply valve and control packages to the British Sugar bioethanol production plant at Wissington, using Foundation Fieldbus and AS-Interface communications in hazardous areas
Few manufacturers are able to offer such a comprehensive range of products including those for zone 1 hazardous areas Over 300 valves controlled by Tyco intelligent network devices have been installed at the Wissington site near King's Lynn

Tyco - an AVID provider of the latest technology
A comprehensive integrated system of control accessories designed for hazardous area or general process applications, is provided by the state-of-the-art AVID range from Tyco Valves and Controls
As the first of its kind to be built in the UK, the installation was officially opened in November 2007 by Lord Rooker, Minister for Sustainable Food and Farming and Animal Health.
Tyco Flow Controls has had a long relationship with British Sugar, stretching back for more than ten years: it is now subject to a framework agreement, the customer having recognised the quality of the Tyco product and service offering.
Commenting on the announcement for British Sugar, Project Manager, Nick Williams said, "British Sugar has completed a number of projects involving large quantities of Tyco products in recent years.

PremiAir actuators from Tyco Valves and Controls
For use in the most demanding process environments, PremiAir pneumatic actuators have been engineered to provide reliable and economical operation for all types of quarter turn valves
We have found them robust and relatively maintenance-free with a good life expectancy.
For the various zoned areas at Wissington we required a wide range of product types and it was useful to be able to source most of these from a single supplier".
Tyco Flow Control supplied the comprehensive package in conjunction with CEL Project Management.
Control valves on the project include variable port control valves, high performance butterfly valves and resilient seated butterfly valves with high temperature resistant XP seats rated at 150C continuous operation.
All control valves are controlled with Tyco SmartCal electro-pneumatic positioners with enclosure to ATEX II 2G EEx ib T4-IP66.
These intelligent positioners employ the open Foundation Fieldbus communication protocol, and feature remote diagnostics.
For the open-close valves the Tyco XA position monitors have been selected.
These ATEX II 2GD EEx d IIB rated units are all linked to the Honeywell control system via an AS-interface network connection.
Using these fieldbuses I/O modules and field wiring were dramatically reduced, resulting in overall project cost reductions.
The Tyco variable port control valve with its floating ball design is designed for precision flow control of high pressure, high temperature and aggressive features typically encountered in the field of bioethanol production.
With features including a custom-designed orifice in the ball to tailor the valve flow characteristic to actual conditions, it also provides high turn down capabilities.
In the all-important area of safety the valve is provided with a fugitive emission port, anti-static devices and blow out stems and a patented stem seal for high emissions control under demanding conditions.
The British Sugar bioethanol plant, which is located alongside the world's largest beet sugar factory at Wissington, Norfolk will produce 70 million litres of bioethanol annually from locally grown sugar beet.
The efficient combined heat and power plant at the sugar factory also provides energy for the bioethanol plant ensuring that bioethanol produced here delivers a carbon emissions saving of at least 60% compared to petrol that originates as a fossil fuel.
