PROCESS CONTROL TRAINING (Industry and Colleges):

Click on Training to see more training details and schedules.
Our products PITOPS, SIMCET and CBT are excellent for classroom and online web-based training for both industry and colleges. Control Engineers, DCS technicians, PLC technicians, operators and students - all will benefit using our training products and training courses. Our training software not only serves training needs but also serves as full-blown tools that can be used in the plant and control rooms. We offer both classroom training courses and online web-based training courses on a regular scheduled frequency every month all year round.


We can examine your process/plant and recommend cost-effective modern advanced control solutions to save you money on new process control-related projects, improve your existing controls to increase plant automation, improve process stabilization and help you move your process in the direction of increased profits. We can optimize and tune all PID controllers in your plant. We can also examine your DCS/PLC and host computer communications and recommend new, powerful OPC (OLE for Process Control) software products for cost-effective and reliable data communications including remote plant data access and monitoring.

APC (Advanced Process Control) PROJECTS:

We can design, implement, commission and support complete APC projects for any chemical, petrochemical, oil-refining, pharmaceutical, electric power, pulp and paper or related-industrial process. Our services include PID tuning optimization, Advanced Process Control (APC) implementation in DCS/PLC or using OPC on a host server computer, real-time communications using OPC, Laboratory Information Management Systems, Production Maximization and Online Process Optimization. We can install complete rule-based or sequence-based controllers to automate your batch or semi-batch processes, conduct automated product grade transitions for any process in a novel, low-cost and robust solution like no other competitor. We possess excellent technical know-how and skills for Polymer Advanced Process Control (polyethylene, polypropylene etc.), Electric Power Plants, Air Separation, Styrene, Refining, Olefins, Pulp and Paper, most Basic and Intermediate Chemical processes.


PiControl has invented new, unique and powerful system identification algorithm that works amazingly well even with complete closed-loop data for multivariable inputs and outputs. The revolutionary system identification algorithm can work with much shorter data sets compared to the current ARMAX (auto-regressive moving average with exogenous inputs) method. PiControl system identification algorithm is a novel technological breakthrough and its performance is far better and it is far simpler than the ARMAX method and also other methods like vector step-response coefficient methods. The technique can be used easily by engineers and even students and technicians without advanced educational degrees nor extensive experience. The algorithm does not need data normalization, is not affected by noise levels and can work well even in the presence of significant unmeasured external disturbances.


We provide online thermodynamics calculations to calculate Vapor Pressure, Enthalpies, Dew Point, Bubble Point and related calculations including online heat and mass balance. These calculations can be run on a server computer on the process control network, reading live data from a DCS/PLC and then writing the calculation results back into the DCS/PLC. Communication is modern, fully OPC-based.


We have skills and experience in many areas: Polymers (Polyethylene, Polypropylene), Polyolefins, Styrene Monomer, Air Separation (Nitrogen, Oxygen, Argon), Hydrogen, Ammonia, Olefins, Aromatics, LNG, Urea, Alcohol, Refining, Cement, Power Plants, Specialty Chemicals, Pharmaceuticals, Oil and Gas. Our skilled and experienced engineers can work with you and design a new control system for any plant or process worldwide.


We believe in simplicity, robustness, low-cost and ease of use by your operators and engineers. We vehemently avoid "black-box" approach and complex tools that need constant support from outside support engineers or software that is hard to understand and use. This helps you minimize your initial costs and also ongoing costs. Our software products, technology and methodology are simple and need little support. Most maintenance work can be done by your own people at the plant. We do provide round-the clock support for you in case you need any technical assistance.


Our software products, technology and ideas can work with any DCS (distributed control system) or PLC (programmable logic controller) manufactured in any country, including Honeywell (TDC3000, Experion), Foxboro/Invensys, Yokogawa, Emerson/Fisher DeltaV, Siemens/Modicon, Allen Bradley, Unitronics, Rockwood, ABB, Bailey, etc. Our software can also seamlessly connect to Aspen Tech, Matrikon, Kepware, Vista-Control, OSI, and other common products. Connectivity is provided via both OPC and Excel.


Our software products and technology can be applied to Distillation Control, Reactor Control, Combustion Control, Boiler Control, Compressor Control, Heat Exchanger Control, Dew Point/Bubble Point Control, Pipeline Control, Environmental Emissions Control, Motor Control, Turbo-machinery Control.
