Tata Chemicals


The Winnington Plant has had a long and illustrious past, in some form or another there has actually been a plant in existence since 1874. Recently  Portasilo undertook this work for Tata Chemicals as part of an extension program to create increased processing plant for Sodium Bicarbonate.


As part of an extension to its sodium bicarbonate manufacturing plant in Cheshire, Tata Chemicals needed a new storage and discharge systems for this material.


To meet the plant’s requirements, Portasilo supplied two 200m3 capacity storage silos, manufactured from stainless steel to provide long-life, corrosion-resistant and contamination-free storage. The silos were designed to accept deliveries from pressurised road tankers, and were fitted with the ancillary protection and safety systems required to prevent over-pressurisation and dust emissions.

To provide fully controllable discharge, and to promote mass flow from the silos, they were fitted with advanced Rotoflo mechanical dischargers. These provide a highly controllable transfer of material into the plant’s existing pneumatic conveying systems.

Both of the 4.5-metre wide, 13-metre high vessels were manufactured and fitted with dischargers and ancillary equipment in the Portasilo factory. This meant that disruptive construction and assembly processes were kept away from the client’s operational site. The ready-to-use vessels were simply transported to site and craned into position in a matter of hours. The route to site was a challenging one for such large vessels, but Portasilo managed all logistical planning and delivery arrangements to ensure the new equipment arrived on site right on schedule, and was installed safely and efficiently.

The client was particularly impressed with the speed of installation on site, which meant there was minimal disruption to the plant’s normal operations.
