Air emissions management

Reducing atmospheric emissions of greenhouse gases and other pollutants is one of the most serious challenges the energy industry is currently facing. We believe that the emissions challenge is more a process engineering challenge than a purely accounting exercise. With our tools and capabilities we are assisting a number of companies to quantify, manage and reduce emissions.

Oil sands / heavy oil

Oil sands / heavy oil operators are currently focusing on innovation and technology development to reduce energy use, operating cost and associated air emissions. Adequate mathematical models need to be developed to help optimize production and processing facilities. We have developed specialized simulation and optimization tools as decision support systems to assist in technology selection and operational optimization.

Relief / flare studies

Calculation of relief loads for various process networks using traditional methods can result in highly conservative results and over-designed relief systems. Due to the time dependency of the simulation, it is also possible to explore staggered relief strategies for specific scenarios. Emergency scenarios can be reviewed using dynamic simulation tools as well as start-up and shut-down situations. Process Ecology can assist your company in the development of high-fidelity dynamic simulation models to perform design checking on flare networks of various complexities. These studies can help in the identification of bottlenecks and opportunities for capital cost savings while ensuring the safety of the plant.

Can a general process simulator be used for flare system design and rating?


Our working approach is to always assist our clients with knowledge and practical advice to ensure there is always a learning component. We also have experience teaching more formal courses around practical applications of process simulation to engineering problems, including HYSYS and Unisim courses. We are licensed to deliver training courses on behalf of Natural Resources Canada in energy efficiency and heat recovery optimization.

Water efficiency

Water is an essential input for all forms of energy production. In particular, water demands in hydraulic fracturing operations have been increasing at fast rate and this is happening in water stressed areas. A number of researchers and industry panels have identified the management of water resources as the biggest challenge faced by producers of shale oil & gas. We can help you identify opportunities for cost savings and water efficiency through the application of optimization models and conceptual design techniques.
