We are in the final stretch before putting our new seawater reverse-osmosis desalination plant into full operation, and I need an experienced commissioning engineer who can step in immediately and steer the hand-over. Your focus will be on three fronts: bring every SWRO process unit through testing and commissioning, train our onsite operations team so they can take over confidently, and fine-tune the system for optimal throughput and energy efficiency. The plant is mechanically complete; piping pressure tests, DCS loops, and MCC energisation are behind us. What remains are the live water runs, performance guarantee runs, chemical cleaning sequences, and all the documentation that proves the plant is ready to deliver product water on spec and on schedule. You will be working side-by-side ...

I have a process-simulation task that must be carried out in ASPEN Plus. The focus is on steady-state process modelling rather than molecular dynamics or reaction-engineering studies, so deep familiarity with ASPEN’s unit-operation blocks, property methods, convergence tools and report generation is essential. Here is what I need from you: • Build or refine the complete ASPEN Plus model based on stream and equipment data I will supply. • Provide the working .bkp file together with a concise run report highlighting key stream results, energy balances and any design-sensitive parameters you adjusted. • Include brief written guidance on how you set up the property method, solved recycles and validated the mass- and energy-balance closure, so I can replicate or extend the...

I’m planning a harmless prank for my YouTube channel and need a small, sand-coloured ball that practically disappears against a typical road or footpath until it’s stepped on or picked up. The core requirements are simple but specific: • Composition: use only natural materials for the ball itself. • Activation: when I add a few drops of organic water type liquid, the surface should turn tacky enough to cling to a shoe or hand, yet lose that stickiness on its own after roughly three hours. • Colour: I want the freedom to tweak shades so the ball can match different outdoor surfaces (brown, grey, beige or any close custom mix I request). Your deliverable can be either a ready-to-ship prototype or a clear, repeatable recipe with step-by-step instructions and s...

This project revolves around continuous industry-trend analysis across the global engineering landscape. I will share a series of R&D initiatives and need concise, data-driven insight into how technologies, standards and competitors are evolving in every major region. Reports should highlight emerging opportunities, disruptive players, regulatory shifts and adoption curves, backed by credible sources and, where useful, AI-generated data visualisations or summaries. A technical background whether mechanical, electrical, civil or another relevant discipline helps you recognise real-world implications and filter out hype. English fluency is essential for our day-to-day collaboration; the ability to communicate findings in Chinese or French is highly valued when we deep-dive into local ma...

I’m putting together a complete, exam-ready collection of study resources that targets both UPSC and NEET aspirants. The focus is on three subject clusters: • Biology & Chemistry (NEET-oriented depth, but cross-referenced to NCERT and relevant UPSC GS sections) • Social Science & Anthropology (UPSC mains-level analysis with concise factual recall sheets) • Ethics & Social Issues (paper-IV style case notes plus contemporary examples) Here’s what I need from you: 1. Modular notes written in clear, student-friendly language. Each module should open with crisp learning objectives and close with a one-page cheat-sheet of key facts and formulas. 2. High-yield diagrams, flowcharts and comparative tables embedded directly in the document (pleas...

Familiar with building chemical structures using avogadro program then doing stimulation studies using DFT method .

We are a Venezuelan engineering company developing an electric immersion heater for extra-heavy crude oil (tubular sheathed elements, U-shaped hairpins, in an ASME VIII pressure vessel). The thermal design is already done. We need an experienced heat-transfer / process engineer to REVIEW it and give an independent opinion — not to design from scratch. ▎ ▎ Service: ▎ - Crude: ~8 °API (Orinoco Belt), highly viscous, with 20–50 % emulsified water ▎ - Heating 70 → 85 °C, line pressure ~4.5 barg (design 10 barg / 200 °C) ▎ - Two models: 100 bbl/d (~9.5 kW) and 600 bbl/d (~53 kW) ▎ - Incoloy 825 sheath, Ø 0.475", no baffles (natural convection dominated) ▎ ▎ Questions to answer: ▎ 1. Is a watt density of ~1.5–1.7 W/in² reasonable for this servi...

I am seeking an experienced Process Equipment Engineer specialising in separation technologies to provide technical expertise during both the tendering and detailed engineering phases of projects. The successful candidate will have extensive experience in process design, equipment selection, preliminary sizing and performance evaluation of separation equipment used in oil and gas, petrochemical, chemical processing and environmental applications. The role will be divided into two distinct phases: - Phase 1 – Tendering & Conceptual Engineering: Review client requirements, develop preliminary process designs, recommend equipment sizing and provide technical input for competitive bids. - Phase 2 – Detailed Engineering Support: Provide specialist process engineering support,...

I’m looking for an experienced ultrasound technologist who can perform and document breast-focused, medical-diagnostic studies. The work centres on high-resolution imaging, with 3D/4D acquisition and Doppler evaluation so that vascular patterns around any lesions are captured in detail. You’ll need to: • Conduct the scan using certified medical equipment capable of true high-definition, 3D/4D and colour Doppler modes. • Export the complete DICOM set plus key stills in a standard image format for quick review. • Provide a concise technical worksheet noting probe type, settings, and any sonographic observations; a formal radiologist read-out is not required. All scanning must follow current breast-imaging guidelines and maintain strict patient priv...
