Two further control systems for chemical supplier

Eurotherm supplies two further control systems to A H Marks.

A long-established working relationship between chemical manufacturer A H Marks and Co and Eurotherm has recently been consolidated with two new control systems projects at A H Marks' Wyke site, near Bradford.

The first project saw the integration of a fourth alpha-chloro-propionic acid (ACPA) reactor into the existing Eurotherm T100 / T3000 based system.

The second project saw batch sequencing software installed on the dichlorophenol (DCP) plant.

Eurotherm have been providing control solutions to A H Marks since 1995, when the ACPA plant was first automated.

Both ACPA and DCP plants are complex multi-path batch operations with recipes downloaded to the relevant reactor to control production.

Access to shared plant items is automatically controlled and the system also includes a comprehensive hold / recovery scheme to allow continuation of a batch after any form of interruption, - even following a power outage.

A H Marks Business Team Manager Mick Baldwin says of the projects: "We have been very impressed with the Eurotherm approach to project implementation.

Throughout all stages, the impact on our resources was minimal and the quality of the product was first class" Since 1995, there have been many further successful projects, including the extension of the original single-reactor ACPA plant control system to a further three reactors, automating the storage and supply of chlorine, installing further plant control systems for PCOC and DCP production, and providing environmental monitoring facilities across all production areas.
