Larry S. Wasik - Process Specialist

Mr. Wasik specializes in process simulation and process optimization, offering services to Pulp and Paper and other clients in the following areas:

• Overall process design to meet product quality, production rate and environmental requirements
• Plant wide process simulation to determine area production capacities, inter-area requirements, overall water and energy requirements, system closed cycle requirements, chemical consumption and operating costs.
• Dynamic simulation to investigate start-up scenarios, tank farm management, batch process scheduling, filtrate management and optimal production scheduling.
• Process de-bottlenecking, process trouble shooting and optimization studies.
• On-line application development for data reconciliation, quality prediction / soft sensors, process visualization and product quality tracking.
• Assistance and training for consulting and operating companies to set up their own custom process simulation.

Process Engineering Consultant Experience

Mr. Wasik spent 15 years with H.A. Simons consulting engineers. As Plant Wide Process Manager, he supervised a group of process engineers responsible for the process design of 5 successful green field mills and numerous re-builds. Mr. Wasik was the lead process engineer on the 1.3 billion dollar expansion at the Howe Sound Pulp and Paper. He played a lead roll in on- site process optimization studies in North American mills as well as in Brazil, Australia, New Zealand and Siberia.

He spear-headed Simons computer process simulation in all areas of the mill using the CADSIM and MASSBAL simulation programs. He developed mass and energy balances for specific areas as well as specializing in plant-wide chemical consumption, water and energy balances. Notably, his Overall Material Balances; Water and Energy Balances; Sodium, Sulfur, Potassium, Chloride and metal ion balances; Pulping and Bleaching balances became standards still in use today.

Plant Experience

After graduating as a Chemical Engineer in 1972, Mr. Wasik had 8 years of experience at Canfor's Port Mellon Pulp Mill. As Assistant Technical Superintendent, he was responsible for the mill's environmental programs, as well as the computerized process control developments.

Simulation Experience

Since 1972, Mr. Wasik has been providing process simulation services to the Pulp and Paper industries, in various capacities with industry and consulting as mentioned above, as well as founding the simulation software company Aurel Systems Inc. At Aurel, he developed the original CADSIM graphical interface program, and led the development of the CADSIM Plus dynamic process simulator. He developed a steam and power dynamic simulation for the reduction of steam demand swings at Kapuskasing. He developed on-line dynamic data reconciliation for the plant wide energy system at Crofton and for batch digesters at Temiscaming. He trained and assisted numerous operating and consulting companies in the use of process simulation.

Uma Ati (Ati) - Control & Optimization Specialist

Uma Ati (Ati) joined Aurel systems after graduating as a chemical engineer specializing in process control and optimization in 2010. Mr. Ati has been involved in developing new filtering techniques, control and optimization methods to improve the performance of CADSIM Plus's Dynamic Data Reconciliation library.

Process Simulation Experience

As an active member of Aurel’s support team, Mr. Ati has been responsible in the following areas:

• Providing online monitoring services on plantwide mass and energy balances using Aurel’s proprietary Dynamic Data Reconciliation software.
• Trouble shooting measurement errors in plantwide mass and energy balances, suggesting corrections to the process measurements.
• Assisting clients in building their process simulation flowsheets and providing online support.

Past Experience

As part of his Master's thesis, Mr. Ati worked on a new approach of modeling of heat exchanger networks for design, monitoring and optimization. This project provided Mr. Ati with a hands-on experience in the understanding and practical implementation of different control and optimization methods. Prior to graduate studies, Mr. Ati worked at Satyam Computers Services, India for 2 years as a mainframe programmer. As part of his Engineering co-op experience Mr. Ati worked at Indian Institute of Chemical Technology in design and development of advance model predictive control systems.
