What is the best dcs solution for a petrochemical plant utility? Utilities like water supply, water treatment, N2, F&G, power substation, etc.

 

Is it a new installation or an upgrade? and if its an upgrade, from what?

 

We have used both Delta V and Matrix Total Control at our Plant. Both are very similar and easy to work with.

 

If the facility has an existing DCS system for the Process side, you may want to tie into it. If so, it may be best to keep the same style DCS.

If you really don't need to tie into an existing system, then for Utilities, you really only need a PLC and HMI's. The expense of a DCS is overkill (in general) for these types of services. Also, the utilities you mentioned are rarely in the same area of the plant, so individual PLCs may work better, each located in the section you are monitoring/controlling.

 

Yokogawa's CS3000 DCS system is probably the best solution. Newly released controller (FFCS) is both powerful and cost effective, and can communicate to most devices. (Fieldbus, Profibus, Modbus, OPC, etc.)

What DCS is installed as main control?

 

I think Yokogawa CS1000 will do.

 

ABB System 800XA; Fully open; complies with IEC-1131 and communicates Profibus, FF HSE, HART, etc....

 

ABB Freelance AC800F is the best solution which provide easy Engineering & Configuration on one window with easy Control Builder F.
