Hire Remote Aspen HYSYS Engineers

Client: Mid-sized North American Oil Refinery.

Challenge: The client faced rising operational costs due to inefficient heat recovery in their crude distillation unit and lacked in-house resources to perform complex pinch analysis using Aspen HYSYS Process Simulation.

Solution: Engibrain deployed a senior process engineer within 72 hours to augment the client's technical team. The remote specialist utilized Aspen Energy Analyzer linked with HYSYS to model the existing exchanger network. They identified sub-optimal heat transfer zones and proposed a retrofit design that minimized capital expenditure while maximizing energy recovery. The engineer worked in the client's timezone, participating in daily stand-ups and ensuring the simulation model matched real-time plant data.

Result: The optimized network design resulted in a 18% reduction in furnace fuel consumption, saving the client approximately $2.4M annually.

Client: European Renewable Energy Startup.

Challenge: The startup needed to validate the feasibility of scaling their pilot electrolysis process to a commercial megawatt-scale plant but struggled to find local engineers with specific expertise in Aspen HYSYS Process Simulation for hydrogen systems.

Solution: We provided a dedicated remote team of two HYSYS specialists and one lead process engineer. This augmented team developed a rigorous steady-state simulation model to analyze the balance of plant (BoP) systems, including water purification and hydrogen compression. They performed sensitivity analyses on various operating pressures and temperatures to define the optimal process window. The team integrated seamlessly via cloud-based collaboration tools, delivering weekly progress reports and validated mass balances.

Result: The simulation confirmed the commercial viability, identifying a configuration that improved overall system efficiency by 12% compared to the initial pilot design.

Client: Global EPC Contractor.

Challenge: An FPSO unit was experiencing frequent shutdowns due to hydrate formation in the gas processing train, and the client needed urgent dynamic analysis using Aspen HYSYS Process Simulation to resolve the issue before a critical production deadline.

Solution: Engibrain matched the client with a specialized dynamic simulation expert within 48 hours. The engineer rapidly converted the client's steady-state model into a dynamic simulation to study the transient behavior during startup and upset conditions. They identified the precise pressure-temperature zones causing hydrate formation and designed a new inhibition injection strategy. The engineer collaborated directly with the offshore operations team to validate the model against field telemetry.

Result: The intervention eliminated unplanned shutdowns related to hydrates, restoring 100% operational uptime and preventing estimated daily losses of $150,000.
