Adsorbents Production
Work began at this site in 1995 and has continued to the
present with ESI being responsible for all of the electrical systems at
the site. This has included the design and upgrade of five control
systems in two manufacturing plants. This has included the integrated
control of over 170 motors and their associated instrumentation from two
central control rooms, one in each plant. Each control system includes a
General Electric 90-70 PLC with a Cimplicity application. Interface to field instruments as well as between each
PLC is performed by a GE Genius local area network with the communications
between the PLC's and the Cimplicity computers by Ethernet. Remote control
of the plants is provided by workstations located throughout the plants,
as well as the computers within the control rooms. Over 50 PID loop
controls are performed by the PLC's that also provide recipe batch control
for this ISO certified manufacturing process. ESI's continued work for
this client has included as built P&ID's, Instrument Lists, control system
schematics, Operational Procedures, and Equipment Lists, all performed
from a client perspective. More recent work has included the addition of
two new control systems to upgrade an existing plant, including retrofits of a
calciner process, two molecular sieve processes, a dense phase conveyor
system, a synthesis process, and screening. Nearly 80 projects have been
performed for this client. Typical project work includes engineering,
programming, and startup.
