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...

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 need a complete formulation for a liquid/powder, multi-purpose household cleaner that relies on biodegradable ingredients only. The end product should wash countertops, glass, and light grease without leaving residue or harmful after-effects in drains or on skin. What I am looking for: • A detailed recipe showing each ingredient, its exact percentage by weight, and its function in the formula. • Step-by-step production procedure that could be followed in a small pilot batch (5 L) and scaled to manufacturing volumes. • Guidance on sourcing the chosen biodegradable raw materials, preferably with at least two supplier options per key ingredient. • Data or references that demonstrate expected pH, viscosity, and shelf-life, plus simple tests I can run to confirm sta...

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%,...

I’m working on turning waste-protein streams into a quantifiable flow of ammonia gas and need a fresh set of eyes on the chemistry itself. The core task is process optimization: fine-tune the alkaline hydrolysis reactions so the conversion rate climbs, the reaction time drops, and the ammonia produced can be captured and measured with confidence. Where things stand • Bench-scale equipment is in place, and I can maintain stable temperature and agitation. • Early runs show ammonia, but yields are inconsistent and the reaction sometimes stalls. • I have log sheets of pH, NaOH/KOH loading, protein concentration, reaction time, and gas readings (Dräger tubes + basic NH₃ sensor). What I need from you • Review my current protocol and datasets, then pinpo...
