Chemical Engineering Jobs

I’m upgrading our process exhaust system and want to bring volatile organic compound (VOC) and ammonia (NH₃) emissions well below current limits. Emission reduction is the sole focus; monitoring and paperwork are handled in-house. Right now I’m weighing four control options: adsorption, biofiltration, catalytic oxidation and a wet scrubber. I need a clear, data-driven comparison that shows which technology—or hybrid setup—will give the highest removal efficiency for our flow rate and composition, and what it will cost to install and run. Please deliver: • Mass and energy balances for each option, including predicted % removal of VOCs and NH₃ • Equipment sizing, PFDs/P&IDs and key specification sheets • Estimated CAPEX, OPEX and maintenance...

I need help with ASPEN HSYS interface i just need help only with separation part as i have attached the file let me know 2 days timeline i would need help on aspen hysys interface u do the simulation and calculations also right also will teach me

I’m looking for a meticulous laboratory technician who can take full ownership of the preparation phase of our secondary-school chemistry practicals. Your main focus will be getting every experiment ready to run: weighing out reagents, mixing stock solutions, laying out glassware, and double-checking that the risk assessments and safety data sheets match what the class will actually do. Beyond that core duty, I’ll rely on you to keep the lab in perfect working order. This includes: • Organising and clearly labelling all chemicals so teachers and students can find what they need in seconds. • Cleaning, calibrating, and logging routine maintenance for balances, pH meters, hot plates, and any other instruments scheduled for use. • Updating the digital invent...

I need a clear, streamlined set of science notes written entirely in plain-text bullet points. The material is meant for students, so every line should be concise, easy to scan, and focused on the key facts and concepts they’ll need for quick review before exams. Scope • Cover the full science syllabus I provide (biology, chemistry, physics topics) in logical sections. • Keep language straightforward—no jargon that a high-school learner wouldn’t immediately grasp. • Use only plain text: no formatting markers, tabs, or rich-text touches, just simple hyphens or asterisks for each bullet. Deliverable A single .txt file containing the bullet-point notes, organized by topic heading, ready for me to drop straight into our learning portal. Acceptance I’ll...

I'm seeking an experienced engineer or machinery specialist to design and possibly create an agricultural bucking machine. Essential Requirements: - Expertise in agricultural machinery - Experience with mechanization in farming - Knowledge of safety and efficiency standards Ideal Skills: - Mechanical Engineering - Agricultural Technology - Prototyping and Manufacturing Please provide examples of similar projects and a detailed budget breakdown.

This project requires the design and evaluation of an engineering product using metallic materials while applying fundamental concepts of materials science and solid mechanics. The project involves defining the design problem, identifying the functional requirements and constraints, and selecting appropriate metal materials that satisfy these requirements. Scientific justification must be provided for the material choice by analysing key properties such as strength, stiffness, durability, and weight. The project also requires analysing the materials processing and manufacturing methods used to produce the selected design. This includes explaining how different manufacturing techniques influence the material’s microstructure and mechanical properties. Engineering tools such as diagram...

Hi, I’m working on a colored flame candle development project and I’m looking for guidance from someone with chemistry experience. Objective:Create solid molded candles (not gel/container candles) that burn with bright visible flame colors such as red/magenta, green, and orange, 3 colour flame candle ideally visible even in daylight. Key constraints for the project: Manufacturing must be simple and scalable. No complicated synthesis or multi-step laboratory reactions. Try to keep things at affordable price, easily available chemicals that can be sourced easily in the indian market And Keep it low cost other online platform are selling it for 15$ for 2 candle around 75-90g each candle which includes labour cost manufacturing marketing packaging and shipping...

I need two new household cleaning formulations—a high-foaming, grease-cutting dishwashing liquid and a streak-free floor cleaner—developed from scratch. Both must be stable, cost-effective to scale, and compliant with common safety regulations. After we discuss my preferred fragrance, colour and any supplier constraints, you will: • Design complete formulations with percentage breakdowns and ingredient functions • Provide step-by-step manufacturing procedures for lab and pilot batches • Specify pH, viscosity and performance targets plus simple in-house tests to verify them • List raw-material sources and SDS references • Outline shelf-life/stability protocols and adjustment tips I will review a small-scale test batch based on your instructio...

I’m working through a Chemical Engineering lab assignment for the College of Engineering & Technology and need an experienced Aspen HYSYS user to guide me from start to finish. The experiment involves building a complete process model, running accurate simulations, and interpreting the results well enough for inclusion in my final report. The specific unit operations and data sets are ready; what I’m missing is the expert touch that ensures my stream properties, thermodynamic package selection, and convergence settings are all sound. I’d also appreciate advice on how to present key findings—energy balances, performance curves, and sensitivity analyses—in a clear, professional format that meets academic standards. Deliverables I’m aiming for: ...

Busco apoyo técnico para llevar de la idea al laboratorio una emulsión botánica de bio-protección a base de aceites esenciales de citronela, lemongrass y eucalipto. Mi prioridad es el desarrollo completo de la emulsión y, dentro de ello, lograr una transparencia absoluta en una solución micelar 100 % estable. El reto incluye: • Formulación y optimización de la emulsión para que sea translúcida, sin fase separada ni turbidez. • Pruebas de estabilidad microbiológica que demuestren al menos 30 días de vida útil en bidones de 30 L. • Asegurar que la emulsión no obstruya boquillas de ultra-precisión durante la aplicación. • Evaluación de compatibilida...
