Introducing the JNE Experiential Learning Fund at McMaster University
This is an initiative to provide students within the Introduction to Civil Engineering course the opportunity to engage in hands-on, real-world learning experiences. This announcement coincides with the 25th anniversary of JNE's establishment of the Endowed Chair in Civil Engineering at McMaster's Faculty of Engineering.
Pilot Plant Automation and Upgrades
Continuously looking to improve our products, we identified an opportunity to automate our wastewater treatment pilot plant, reducing the required labour to maintain efficient operation. We also installed mixed reaction tanks below the existing plug flow reactor and made the various chemical reaction systems selectable via a tee branch system.
Solving Excess Wastewater Problem for Greenhouses
Greenhouse growers may run out of holding capacity for rainwater during the Spring and Fall rainy seasons. Because this rainwater and plant run-off contacts rooftops, floors, plants, etc., it often has pollutant levels surpassing provincial limits for discharge to the natural environment. By reversing a standard wastewater treatment process, JNE’s pilot plant can safely discharge excess water run-off while recycling and storing nutrient-rich water for production use.
Wastewater Treatment: Drilling, Tunneling, and Mud Separation Polymers
Modern day mining, tunneling, jet and pressure grouting, drilling, and similar activities require a lot of water for operation. These industries use water to remove ground material, cool and lubricate machinery, and control dust. This contaminated water cannot go back into the ground as it may bring these pollutants directly into other important underground water sources such as aquifers and water tables. Luckily, JNE Environmental has the solution.
Wastewater success for skin care and beauty products manufacturer
Wastewater from skin care and beauty products manufacturing can be very difficult to treat due to the complex ingredients used. When JNE Environmental was approached to perform testing on wastewater from a cosmetics manufacturer, we were excited to see how we could treat all levels to within sewer by-law compliance limits.
Pipe Expansion Loop Design
Pipe Expansion Loop Design Published January 2023 Keywords Expansion Loops Piping Flexibility Stress Compensation Summary The purpose of this file is to illustrate quick sizing of the expansion loops. Pipe expands when heated and contracts when cooled. When a pipe allowed to move (unrestrained), it is free to expand or contract without generating thermal stresses. Once the pipe is restrained at the ends (by anchors or equipment nozzles), thermal stresses can be generated. These stresses are a result of a system’s lack of flexibility and ability to compensate for thermal expansion or contraction. Expansion compensation in the form of expansion loops, 90° elbows and z-bends are a simple, low cost and low maintenance design elements that can be used to increase system flexibility and decrease pipe stresses. These arrangements can be observer in Figure 1. Hints 90° changes in piping direction are the most efficient design to absorb thermal expansion/contraction. Utilize any natural flexibility of the piping system (any lateral offsets, changes of direction). Use strategic location for the pipe supports to avoid over restriction of the system. Share Project/Case Example Oxygen and Natural Gas supply lines to cutting tables. On this project there was a 4” oxygen line and a 2” natural gas line that ran 286ft and 160ft in length respectively. Both these lines had a design temperature of 140°F and -40°F, resulting in 4” of thermal expansion in the oxygen line and 2.25” of expansion in the natural gas line. To overcome this expansion, a couple methods were used and utilized. Both lines had to run vertically from near grade for approximately 28’ before a 90 degree change in direction. This change in direction allows for some thermal expansion compensation as can be seen on Figure 1. The Oxygen line then ran straight for approximately 282’, and natural gas line ran for approximately 157’. Due to lengths of these long straight segments of pipe, expansion loops were required to be added to compensate for thermal expansion. Both lines then ran back down to grade taking advantage of 90° changes to get down to grade and into building mirroring elbow and z-bend patterns in Figure 1. The material used for this case was carbon steel. The calculations for this process in the project were followed in as detailed in the Solutions/Best Practices section of this document. Codes and Standards: ASME Piping Codes B31.1, B31.3 Solution/Best Practice 1. Calculate the expansion (or contraction) in the pipe. The first step in sizing an expansion loop is to calculate the thermal expansion of the pipe run. The sizing of the expansion compensation (loops) may be done by the use of simplified equations, nomograms or tables. The first step in sizing the loop is to calculate piping expansion Δ. Δ =α lo( Tf-To) Where: α is material’s linear [...]
JNE reaches annual Movember fundraising target
With this year’s fundraising total, JNE has raised over $25,000 towards men's health awareness since the team’s formation in 2018. We are extremely grateful to everyone who supported our efforts this year and helped us contribute towards a global mission of reducing men's mortality rate by 25 per cent by 2030. We are proud to support the Movember Foundation and look forward to future fundraising efforts.
JNE at the OSPE Engineering Conference 2022
Representatives of the JNE Group of Companies attended the Ontario Society of Professional Engineers (OSPE) Engineering Conference in Ottawa, Ontario on November 3, 2022. The event, Canada's largest forum for engineering, diversity, and recruitment, was a fantastic opportunity to connect with young professionals, students, and subject matter experts in the engineering industry.
