i'm working on a process plant where there will be a Safety Integrated System (SIS) designed for the process.
It occurred to me that it would be helpful to designate the instrument "bubbles" on the drawings if they are components of this system.
I'm curious to know from others if anyone has...
I have worked most of my career for what is usually called A&E firms or Consultant Engineers. We make the construction drawings and develop instrument specifications for chemical process projects. Data sheets for instruments, schematics for connection to the PLC or DCS, instument location plans...
I'm just getting in to a security upgrade for a client who now uses microwave tx/rx technology to protect against perimeter breaches. I see that there is now another technique used similarly that senses for a disturbance in the light sent through a fiber optic cable that would be attached to a...
The more I study the possiblities the more uncertain I become about what to use. We are doing an estimate for a chemical process plant where Foundation Fieldbus(FF) has been decided for use with Analog - Transmitters and Positioners.
The question is what to do with the on-off valves and...
In designing a duct bank for a chemical plant, I was going by our company's standard detail for underground ductbank which calls for 6" separation between conduits with instrumentation & low level communication circuits and low voltage ducts (in our case 480 V conductors for lighting and 120V...
I'm currently doing a study of existing lightning protection at a chemical plant. I will be making recommendations to the client about maintaining his current NFPA 780 style protection with air terminals, conductors and ground rods.
I have also been reading much about the Dissipation Array...
