Process Engineering Jobs

requires stress analysis on a reactor nozzle. They intend fitting a dip pipe through the nozzle, but need to know that the nozzle is suitable, and need to be sure the dip pipe can do the job, bearing in mind that the vessel is fitted with an agitator. Do you think this is something you can help with? In addition to the physical data the things I’d like you to consider are: Longest dippipe we could have without internal vessel modifications (to add supports etc..) Mechanical design for a directional dip-pipe to direct recirculation to the vessel wall , and if this is ok for stress/erosion risk on the vessel wall given the high recirculation flow rates Vessel fabrication drawings will be provided Nozzle will be used for the dip-pipe Vessel data sheet will be provided with process an...

I need a qualified engineer to take my 0.1 MGD membrane bioreactor wastewater project from draft design to full regulatory approval under both 30 TAC 217 and 30 TAC 210. The sole focus is permitting—preparing every technical document, completing the TCEQ application, responding to agency comments, and staying engaged until the approval letters are in hand. The design basis, process flow, and preliminary calculations are available; what I lack is the polished submittal package and the experience navigating TCEQ reviewers. Because the plant will serve reclaimed-water purposes, the submission must satisfy 217 design criteria and 210 reuse requirements simultaneously. Speed matters—I am aiming for an ASAP turnaround and will review and sign off on deliverables the moment they ar...

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. Licensed Software to be used such as PV Elite (Hexagon) or COMPRESS (CodeWare) or AutoPIPE Vessel (Bentley) 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 calculation...

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’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...
