Project History, Chemical Facilities The following is a sample of the chemical facility projects performed by ACE Automation employees. In addition to programming, typical jobs required: investigation of existing plant operations writing of the functional specification for system design engineering services installation of the hardware user training, and startup Polyethylene Pellet Storage Facility - Texas Created PLC programs for each of three warehouses to control storage and movement of polyethylene pellets between production silos, storage silos, rail cars, truck loading, and other receiving vessels. Programs kept track of products in silos, use of common valves in piping, control of pumps, transfer routines, etc. Also included automatic daily valve rocking routines and silo level measurement. Completed over 100 screens with 15,000 PLC tags using National Instrument’s Lookout for each of the three warehouses. Developed a simulation system using Cape Software, and conducted a full simulation for all three warehouses prior to system commissioning. Programmed in APT. Polyethylene Pellet Storage Facility - Texas Wrote a Functional Specification document to be used in RFQ for a plant control system. Interviewed operators and management and worked with technicians to gather information needed to create document. Petrochemical Refinery - Trinidad Installed new remote bases and upgraded controls on two 565T hot backup PLC systems and one 555 PLC. Modified the existing control logic and added new functions. Programmed in APT and TISOFT. Petrochemical Refinery - Trinidad Second trip to plant. Developed a PCS HMI system to replace the existing TISTAR system. Completed installation of new graphics and trained operators. Programmed a new 4-tower dehydrator control system, and modified 3 existing PLC systems. Programmed in APT and PCS. Petrochemical Refinery - Trinidad Third trip to plant. Upgraded the PCS HMIs to version 3 w/ optical storage devices. Modified various HMI screens and 3 existing PLC programs. Programmed in APT and PCS. Mass Flow Totalizer for Fractionating Plant - Ohio Modified the existing PLC system to include meter pulse counting and factoring for three process streams, using a Siemens high-speed counter/encoder module. Programmed in APT. Fuels Processing Facility – Texas PLC Programs and Operator Interface for butane treating towers – This system consisted of 1 TI545 PLC and 1 operator interface. The purpose of this system was to automate 4 treating towers with the ability to regenerate and run online. Programmed the PLC. Developed a touchscreen operator interface. Held training classes for all shifts of operators. Provided startup support. Programmed with TISOFT and Interact. Chemical Facility - Texas This system uses 4 Siemens S7 PLCs for data collection of chemical reactors. The purpose of this system is to measure temperatures at the different beds in the reactors, display the current bed temperatures (15 per bed), and log the data to disk for later retrieval. Designed the operator interface screens for data retrieval. Setup communications via RS422 and Modbus between the PLCs and operator interface. Set up automatic logging of data using script language in Intouch with the ability to copy the logged files over the company network. Programmed in WonderWare InTouch.
