Process Engineering Jobs

I’m developing a compact, continuous-operation spray dryer for laboratory use—target capacity is roughly 5 L/h—and I’m looking for a mechanical engineer who can turn the concept into a build-ready package. The system must incorporate: • Drying chamber sized for 5 L/h throughput • Rotary atomizer as the chosen atomizing method • Electric heating elements appropriate for lab safety and control • Blower and airflow ducting tuned to the thermal load • Cyclone separator or equivalent powder collector • All wetted parts in stainless steel Deliverables I need from you: • Complete 3D CAD model (STEP or native format) • 2D fabrication drawings (PDF/DWG) • Comprehensive Bill of Materials • Basic overview calc...

Hello, We operate a batch plastic pyrolysis plant with capacity 7.5–8 ton per batch. Feedstock: LDPE, HDPE, PP plastic waste. Our goal is to improve process performance and oil output. Current issue: Sometimes wax formation becomes high, and oil yield becomes lower than expected. We want help in understanding: • how to reduce wax formation • how to increase oil yield • how to improve diesel range oil (C12–C18) • how to stabilize vapour temperature • how to improve condenser performance Plant already running with: reactor vapour pipeline separator multi-stage condensers We have temperature readings from plant and process data available. We are looking for a Chemical or Process Engineer who understands: pyrolysis thermal cracking distillation h...

JOB TITLE Freelance Chemical / Process Engineer – Plastic Pyrolysis Optimization PROJECT DESCRIPTION We operate a 7.5–8 TPD batch plastic pyrolysis plant processing LDPE, HDPE and PP. We are looking for a freelance Chemical / Process Engineer to help optimize plant performance and reduce wax formation. The plant is already operational. We need process optimization, not basic plant design. OBJECTIVE OF CONSULTATION • reduce wax formation percentage • increase liquid oil yield • increase diesel fraction (C12–C18 range) • improve vapour cracking efficiency • stabilize vapour temperature profile • optimize condenser temperature staging • improve consistency between batches PLANT CONFIGURATION (SUMMARY) • rotary batch pyrolysis reactor &...

I need a seasoned technician or trainer who already works day-to-day with paper-bag converting lines to walk me through advanced machine operations for producing flat pharmacy pouches. I’m past the beginner stage—I can set up and run standard bags—but I want to master every dial, sensor and knife adjustment that affects accuracy, speed and waste when the machine is configured for medical-grade paper. The sessions should cover: • Complete start-to-finish change-over to flat pharmacy formats • Fine-tuning tension, temperature and glue stations for sterile-grade paper • Real-time demonstration of quality checks, inline printing alignment and stack delivery • Recommended maintenance routines that keep the line running continuously at high output ...

This is a highly challenging, research-level task that requires strong expertise in chemical engineering and advanced process simulation, particularly Aspen Custom Modeler (ACM), Aspen HYSYS, Aspen Plus. The project involves making membrane block for gas separation using Aspen Custom Modeler. Here is a reference for the result of the membrane block should be able to achieve: Merkel et al. (2010) - Power plant post-combustion carbon dioxide capture: An opportunity for membranes (Paper link also attached to this project for direct download). Scope (Summary): Develop a complete Aspen Custom Modeler (ACM) model of a membrane Implement mass & energy balances, reaction kinetics, and mass and heat transfer correlations and every other correlation. Deliver: - ACM model file - ACM model ...

I need a complete engineering package for a 72" × 26' three-phase separator rated to 65 bar, dedicated to oil and gas separation. The vessel, piping, and skid must comply with ASME Section VIII Div 1 (2025) and all associated codes that apply to a high-pressure production environment. Scope of work Please develop every aspect of the skid-mounted system—from process design through fabrication drawings—so that a shop can move directly into manufacturing once the package is approved. Because production schedules are tight, I’m looking for final, issue-for-construction documents as soon as possible. Required deliverables • Design calculations for the separator shell, internals, connected piping, and skid, including full stress analysis • Lift...

I’m hiring a fresher—10th pass or higher—to run our industrial machines during the day shift. You don’t need prior factory experience; I’ll provide the hands-on training you’ll need to start the line, monitor throughput and shut down safely. The one skill you must already bring is a sharp eye for Quality Control inspection. Throughout the shift you’ll spot-check parts, record variances and flag anything outside tolerance before it leaves the cell. Accuracy and consistency matter more to me than speed, and I’ll show you exactly how to use our gauges, calipers and digital logs so every reading is traceable. Daily work will revolve around: • Industrial machine operation under set parameters • In-process quality inspections and basi...

I’m building a dynamic model in Aspen HYSYS and need a sharp second set of eyes to get the simulation fully set-up and running smoothly. The core flowsheet is drafted, yet several unit operations still require proper dynamic parameters, controller configuration and convergence tuning. I’d like you to jump in, review what’s there, finish the remaining specifications and make sure the case transitions cleanly from steady-state to dynamic mode without warnings or calculation stalls. To keep things efficient, please tell me about your direct, hands-on experience with Aspen HYSYS dynamic simulations—years of use, the kinds of processes you’ve modelled, and any special areas of expertise (e.g. columns, compressors, flare systems). No need for lengthy proposals; a c...

I’m looking for a concise P&ID that pulls together the key electrical and pneumatic elements of my system in one clear sheet. The goal is a high-level overview—major components, interconnecting lines, and basic control logic—so technicians can follow the flow without digging through pages of detail. Any mainstream drafting platform is fine (AutoCAD, SolidWorks Electrical, EPLAN, etc.) as long as I receive both an editable source file and a print-ready PDF. I’ll provide hand-sketched notes and a component list once we kick off, and I’m aiming for a quick turnaround of just a few days. Please focus your bid on your relevant experience with similar mixed-discipline diagrams and include one or two sample drawings that demonstrate you can keep things clear an...

Busco un ingeniero químico que concluya el desarrollo de una emulsión de aceites esenciales—citronela, lemongrass, eucalipto limón, lavanda y menta—estabilizada con Polysorbate 20 o otro compuesto (Segun Ingeniero). La emulsión deberá: • Mantenerse estable y translúcida bajo 60 bar (860psi) en un sistema dry mist con toberas de 0,20 mm, sin generar sedimentos ni obstrucciones. • Conservar el aroma característico de cada aceite y no manchar superficies en espacios comerciales. • Cumplir con las especificaciones técnicas que ya poseo: proporciones preliminares de ingredientes, requisitos de desempeño del producto final y métodos de prueba/validación que deberás afinar.
