This section of 2500 words include: - Overview of how safety & sustainability are considered at various stages of the plant design process, covering: Design for Safety (DfS) considerations, Design for Maintainability (DfM) considerations, Design for Sustainable Development (DfSD) considerations - Conceptual Research & Design Stage: Evaluation of Reaction Pathways & Safety Hazards Analyze the Safety Hazards associated with the various reaction pathways using the ...

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.

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: ...

I am looking for someone who can create biomass gasification from EFB and carbon capture by MEA. The result for both biomass gasification and carbon capture by MEA need to be validated with results from the journals (biomass gasification and carbon capture by MEA has their own experimental journal). Both of them needs to be done by Aspen Plus. At the first stage, there are 2 different simulation : biomass gasification & carbon capture using MEA. The biomass gasification simulation needs to have the same result of syngas composition (CH4, CO, CO2 and H2) with the result from journal. The result needs to be validated based on the temperature at 650,700,750,800,850 and 900 Celcius. While for the MEA-carbon capture, the results need to be validated by the concentration of the MEA at 30%,...
