Mixing equipment EPCm (Grangemouth UK)

Client: Ink manufacturing operator
Location: Stirlingshire, UK
Duration: 9 months
Contract Type: EPCm bespoke terms

This project was phase 2 of a total project spend of £5M, the project was split into 2 phases due to client commercial reasons.

This process was the Mixing of Pigments with other chemicals to create a Mill base of dispersed Pigment for the manufacture of Ink.

Scope

The scope of this project was to specify and install technology to handle flammable pigment into a liquid dispersion, using a solids addition hopper, dust extraction, Netzch Epsilon Mixer Pump and a pre-mix vessel. The Pre-Mix vessel is jacketed and temperature controlled via bespoke designed Heat Cool Loop, consisting of Heat Exchangers and a recirculation pump. This dispersed pigment is then Milled using Netzch Mills to form a Mil base, for use in another part of the process.

All of this equipment had to be installed in the available footprint of an existing plant. With tie-ins to existing services for Power, Low Pressure Steam, Cooling Water, Instrument Air, Purified Water and Effluent. The Mills required a dedicated electrical panel, Control Panel and Control System, that had to integrated into the main plant control system. Instrumentation was part Profibus for AutoValves and traditional 4-20mA Analogue for Measurement devices.
