During my academic journey, I acquired a solid knowledge in the fields of analytical chemistry, organic chemistry, and materials chemistry, as well as in subjects related to heat balance and transfer, fluid mechanics, and mass transfer. Additionally, I mastered unit operations such as drying, absorption, adsorption, distillation, crystallization, and evaporation. I also gained expertise in using simulation software such as Aspen HYSYS and PIPESIM, primarily in the petrochemical field. I became proficient in using office software like Excel, including programming in Excel, as well as optimization software such as NEMRODW. Furthermore, I was capable of sizing equipment and had knowledge in water treatment processes and the sizing of water treatment.

Perico Society Internship  As an intern at Perico Society, I gained valuable experience in the field of compressor sizing. During this month internship, I learned how to accurately size compressors for various industrial applications. This involved analyzing factors such as flow rate, pressure, and temperature to determine the appropriate compressor model and capacity. Through hands-on training and mentorship from experienced engineers, I developed a strong understanding of compressor selection and performance optimization. I also had the opportunity to participate in project planning, troubleshooting, and documentation processes related to compressor systems. This internship allowed me to apply classroom concepts to real-world engineering challenges and deepened my technical skills in a dynamic, fast-paced environment. The knowledge and experience I gained have prepared me well for a career in mechanical or process engineering.

The process of manufacturing jeans involves several key stages, from selecting materials to the final garment construction. Here is a general overview of the process: Denim Selection: Denim, a durable cotton fabric, is typically used to make jeans. Different types of denim may be chosen based on weight, texture, and color. Fabric Cutting: Denim pieces are cut according to specific patterns to form different parts of the jeans, such as legs, waist, and pockets. Assembly: The cut pieces are sewn together using specialized sewing machines to form the jeans. Strong sewing techniques are often employed to ensure the durability of the finished product. Finishing: Finishing touches, such as attaching rivets and buttons, are added to reinforce stress areas and for aesthetic purposes. Washing and Treatment: Jeans are often subjected to various washing treatments to give them a worn or faded appearance. Techniques such as stone washing, sandblasting, or enzyme washing may be used to achieve different fading and texture effects. Dyeing and Painting: Jeans can be dyed in a variety of colors using chemical or natural dyes. Additionally, painting techniques may be used to add patterns, artwork, or special effects to the fabric. Special Effects: Special effects on jeans may include distressing techniques, shredding, embroidery, patchwork, hand-painting, or other creative methods to give the jeans a unique and personalized look. By combining these different manufacturing steps with a variety of dyeing, painting, and special effects techniques, jeans manufacturers can create a wide range of styles and designs to meet fashion trends and consumer preferences

mproving the performance of regular diesel by identifying and adjusting its cold filter plugging point (CFPP) to ensure better efficiency and optimal use in various weather conditions. Key Points: Cold Filter Plugging Point (CFPP): The CFPP is a crucial indicator to determine the diesel's ability to be filtered at low temperatures without clogging the filters. A low CFPP signifies better performance in extremely cold conditions. Chemical Analyses Used: Gas Chromatography (GC): Identifies and quantifies the hydrocarbons present in diesel. Infrared Spectroscopy (IR): Used to detect chemical compounds and assess the purity of diesel. Sulfur Content Analysis: Crucial measurement to comply with environmental standards and improve diesel quality. Analysis Technologies: Differential Scanning Calorimetry (DSC): Used to determine the freezing points of various diesel components. Rheometers: To evaluate the viscosity and rheological behavior of diesel at different temperatures. X-ray Fluorescence Analysis (XRF): To measure trace elements and metal contaminants.

This internship is an accelerated training program where we learn labor techniques in the plastics industry as well as mold design. We also learn how to use plastic manufacturing machines and program CNC machines. Additionally, we gain proficiency in extrusion, blow molding, thermoforming, and injection techniques.
