Capabilities
Gas Processing Plant Control SystemsWilson Mohr has extensive history
in providing fully integrated plant
automation systems for new projects or
retrofits in the midstream gas processing
market. The automation systems may
include Distributed Control Systems
(DCS); Programmable Logic Controllers
(PLC); Safety Systems; Fire & Gas
Systems; Operator Stations and field
instrumentation. The complete solution
will be engineered and documented
to provide excellent performance and
minimize costs.
Controls for:
Separators
Heaters
Glycol Dehydration Systems
Mol Sieve Systems
Amine Systems
Electrostatic Coalescers
JT Plants
Dewpoint Plants
Mechanical Refrigeration Plants
Compressors
Fire & Gas Detection Systems
Wellhead Control Panels
Field Communications Architecture
The system will provide data collection & controls from remote I/O;
packaged equipment controllers; and MCCs. Fire & Gas and ESD functions
are incorporated into a SIS system, utilizing redundant hardware. Fire & Gas
System includes flame detection; toxic and combustible gas detection, at
sources and fence line. Graphical interface for operations includes displays
for process overviews, controller faceplates, alarm status & history, process
trends, maintenance screen and network health. Public Address/ General
Alarm system is integrated with Voice over IP for telephone system.
Communications to enterprise management systems or historical archiving
systems are also possible.
Wilson Mohr utilizes a vendor neutral approach to create unique solutions
for each specific application. For older existing facilities Wilson Mohr can
make upgrade recommendations to take advantage of newer technologies
and comply with new standards and regulations. This can improve plant
performance and increased safety.

Standardization
Wilson Mohr has developed a standardized approach
to meet customer demands for safe, cost effective,
quickly executed control system. We start with a re-
dundant , dual media communication network. Field
I/O is routed through junction boxes or Remote I/O
panels with redundant power and communications.
Redundant controllers utilize uniform configuration
commands and objects to insure clarity of functional-
ity and ease of recognition. Redundant data servers
handle engineering station and I/O server functions.
Hardwire interconnection between control system and
skids & process equipment utilize process wiring so-
lutions. Field instrumentation packages with proven
performance are available.

Safety Instrumented Systems
Wilson Mohr can provide support in the development
of your plant Safety Requirement Specification solu-
tion. After all potential hazards have been identified
and layer of protection analysis has been completed,
the Safety Instrumented System with all the Safety
Instrumented Functions requirements defined can be
designed. Our engineering staff will select technology,
select architecture, determine test philosophy and per-
form reliability & safety evaluation. Once the Safety
Integrity Level is achieved, the Safety Instrumented
System detail design can be completed. Loop dia-
grams, wiring diagrams, logic diagrams, panel layouts,
PLC programming are all part of the complete control
system.
