Mechanical and Structural design of Disk baffle for Oligomerisation reactor

We executed this project for a SABIC Petrochemical plant located in Al Jubail, Saudi Arabia. The proposed disk baffle is expected to serve the function of separating the condensate in the Oligomerisation reactor. We developed the conceptual model of the disk baffle using our expertise in core mechanical design and optimized the design using Finite Element Analysis (FEA). We provided detailed fabrication drawings to the customer and supported them during Fabrication process. Read More

Pollution dispersion studies for SABIC chemical plant stack using Computational Fluid Dynamics (CFD)

We executed this project for a SABIC chemical plant in Al Jubail, Saudi Arabia. The objective of the project is to dilute the concentration of pollutants in the high-rise stack by injecting steam generated from the waste heater boiler. We carried out CFD analysis and analyzed the reduction in the concentration of pollutants. We designed a sparger which enabled us to increase the effective height of the stack. Read More

CFD analysis of Helical Agitator

Helical agitators are a type of mixing equipment consisting of ribs or blades arranged in the form of a helix. This design creates axial motion and vigorous fluid motion inside a vessel. It is often used to mix viscous materials. The helical agitator is commonly used for low Reynolds number industrial mixing. The helical design of these agitators generates high shear rates and ensures thorough mixing of materials with different densities and viscosities. Helical agitators are used in polymer industries and other industries that require the use of quite viscous materials. Read More

Cement grinding plant Roller shaft re-design and FEM analysis

Frequent failure of the shaft used in cement grinding units at our customers plants across India warranted an independent review of the shaft design. Niharika Computational Engineering Solutions Pvt. Ltd. (NCES) was chosen for this Independent review task using the finite element method. NCES was provided with information on the working principles of the roll press system and also information on the material used for the shaft that is in question, along with detailed drawings. To better understand the design of the shaft for various loads that it would see during normal operation, a comprehensive study was undertaken by the NCES team. This study involved using Finite Element Analysis (FEA) and performing static analysis for load distribution, modal analysis for estimating natural frequencies, rotor dynamics for checking resonance due to vibration, and dynamic analysis to estimate endurance limit under complex loading and crack initiation and propagation. NCES team has modified the shaft design and recommended a new material that addresses the frequent failure of the shaft. Read More

Structural analysis of crude oil storage tank

The scope of the work is to validate the structural design of a 32 Kilo Litre crude oil storage tank employed in the Adani Petrochemical plant. Our customer has approached us to validate the tank and cone roof design using Finite Element Analysis (FEA). We conducted FEM analysis, worked collaboratively with our customer, and enabled them to address all the minor uncertainties. In the end, we concluded that the design met all the structural requirements. Read More
