Capability comparison
| Decision criterion | SuperPro Designer | Roebling | Acatian |
|---|---|---|---|
| Primary offer | Mature desktop process simulator. | Engineering partner plus AI-native deterministic capital-project platform. | Shared browser software for bioprocess modelling and plant decisions. |
| Process simulation | Batch and continuous modelling with 140+ documented unit procedures, reactions, VLE, balances, sizing, and costing. | First-principles physics and a dynamic project model are emphasized; the public page does not publish a comparable unit-operation catalogue. | Editable plant graph, component and energy balances, reactions, operating modes, ODE/PDE models, physical constraints, and connected evidence. |
| Bioreactor scale-up | Fermentor and equipment models support established flowsheet calculations. | Biomanufacturing and industrial scale-up sit within the broader engineering engagement. | Links kinetics, OUR/OTR, kLa, mixing, gas handling, shear, heat removal, geometry, CFD screening, downstream load, and uncertainty. |
| Scheduling and capacity | Batch scheduling, resource tracking, throughput analysis, debottlenecking, and integration with SchedulePro. | Manufacturing scheduling detail is not specified on the official overview reviewed; confirm the required scope directly. | Finite-capacity batches and campaigns across equipment, rooms, operators, utilities, inventory, CIP/SIP, maintenance, holds, QC, and changeovers. |
| TEA, CAPEX, and OPEX | Equipment costing, thorough process economics, and environmental assessment within the simulator. | TEA, unit economics, AACE cost-estimate classes, feasibility, option selection, FEED, and FID packages are central to the offer. | Process-linked COGS, CAPEX, OPEX, cash flow, NPV, IRR, break-even, cost intervals, sensitivity, and source ownership for screening and engineering review. |
| LCA and sustainability | Environmental impact assessment, emissions, and pollution-control modelling are documented. | Sustainability scope is not detailed on the main official overview reviewed. | Life-cycle inventory, functional unit, system boundary, allocation, impact categories, data quality, low/base/high ranges, and sensitivity stay tied to the process version. |
| Scenarios and uncertainty | Parametric sensitivity and optimization can be automated through COM and external tools. | Thousands of scenarios and traced uncertainty are prominent parts of the platform message. | Named branches, before/after model differences, ODE/PDE trajectories, parameter intervals, sensitivity tables, and Monte Carlo-ready exports. |
| Collaboration and traceability | Strong individual modeller workflow with customizable reports and file-based handoff. | Shared live platform, source-linked figures, data library, and expert review. | Roles, invitations, comments, model versions, source lineage, review state, rollback, audit context, and controlled exports around the same model. |
| Automation and data | COM/OLE integrations with Excel, MATLAB, C#, Python, and other Windows tools. | Centralized engineering data and an AI layer that assembles work around a deterministic solver. | CSV, TSV, JSON, and historian-style intake plus REST, Python jobs, webhooks, connectors, and structured engineering packages. |
| Best fit to evaluate | Teams prioritizing a mature desktop simulator, broad established unit-operation library, and familiar calculation workflow. | Teams procuring an expert-led capital-project package from early unit economics toward FEED or FID. | Process development, MSAT, CDMO, manufacturing, TEA/LCA, and engineering teams that need one shared, versioned bioprocess decision system. |
End-to-end model
Start with components, mixtures, reactions, yields, recycle, purge, emissions, waste, utilities, and every open plant boundary. A defensible bioprocess mass balance reports unit-level and plant-level residuals rather than only a rounded dashboard total.
Batch, fed-batch, perfusion, continuous, and hybrid processes need time-resolved state models. Biomass or viable cells, substrate, product, metabolites, feeds, volume, oxygen demand, gas transfer, and heat generation should propagate into harvest and downstream capacity. See the Acatian bioprocess simulation software workflow.
Scale-up must evaluate kLa, OUR, OTR, mixing time, power per volume, tip speed, shear exposure, gas flow, oxygen enrichment, backpressure, heat-transfer area, cooling duty, broth rheology, and working volume. Qualified 3D CFD still requires an external solver, mesh evidence, convergence, and experimental validation.
Plant capacity depends on equipment occupancy, recipes, setup, transfers, hold times, CIP/SIP, shared skids, rooms, operators, utilities, inventory, QC release, maintenance, and campaign changeovers. A finite-capacity schedule should explain every queue and bottleneck.
A connected TEA and LCA model traces titer, yield, productivity, media, buffers, resins, filters, single-use systems, labor, energy, water, waste, facility utilization, equipment, and scale into COGS, CAPEX, OPEX, NPV, IRR, emissions, and environmental impact.
A bioprocess digital twin becomes useful when model state, batch records, historian data, laboratory assays, equipment states, parameter sources, uncertainty, versions, review status, and APIs remain synchronized. AI can help structure work, but conservation laws and deterministic solvers should calculate engineering outputs.
Industry and role fit
Selection logic
Your qualified SuperPro Designer model, unit-operation library, local Windows workflow, costing database, reports and experienced users already answer the decision. Do not migrate a validated model simply because a newer delivery model exists.
You need experts to deliver unit economics, a feasibility study, option selection, pre-FEED or FEED work, an AACE-aligned cost estimate or an FID package—not only access to a self-directed software workspace. Confirm scope, estimate class, deliverables and professional responsibility contractually.
You need browser collaboration and want the flowsheet, dynamics, equipment, schedule, TEA, LCA, company data, assumptions, model branches, sources, comments and exports to move together. Evaluate it first for cross-functional bioprocess decisions that currently span simulator files, spreadsheets, scripts, reports and meetings.
Buyer checklist
Proof before migration
Select one customer-owned process with approved stream tables, equipment duties, batch timing, economic results, sources, and known limitations. Record the exact software version and calculation basis.
Set tolerances for mass and energy closure, trajectory error, equipment sizing, schedule events, throughput, COGS, CAPEX, LCA inventory, sensitivity direction, runtime, traceability, and exports before rebuilding anything.
Separate numerical implementation, default data, boundary definitions, property methods, schedule logic, costing year, and evidence quality. A matching headline number can still hide incompatible assumptions.
Keep the trusted model or engineering package as the reference until the new workflow meets the agreed technical and governance criteria. Document gaps instead of forcing a migration conclusion.
Change batch size, titer, feed profile, recovery yield, equipment train, campaign sequence, electricity mix, or site. Confirm that process, capacity, economics, and environmental outputs update together and remain auditable.
Give the model and exports to process development, MSAT, manufacturing, facility engineering, TEA/LCA, and management reviewers. The best tool is the one that improves the actual decision and survives independent challenge.
Frequently asked questions
Yes, for overlapping bioprocess modelling work: flowsheets, mass and energy balances, equipment, batch and continuous operating modes, scheduling, economics, and environmental analysis. It is not a file-compatible clone. SuperPro Designer has the longer commercial history and broader established unit-operation library; Acatian emphasizes browser collaboration, native versions, governed data, connected dynamics, TEA/LCA, and API-first handoff.
For some early bioprocess decisions, yes: both can support scenario modelling, techno-economic analysis, traceability, and integrated engineering reasoning. They are not one-for-one substitutes. Roebling publicly describes an expert-led engineering offer extending toward FEED and FID, while Acatian is a browser software workspace for teams building and reviewing their own versioned bioprocess model.
There is no universal winner. Choose against a defined process and decision. Prioritize model scope, calculation transparency, validation evidence, scheduling depth, economic and LCA boundaries, data integration, collaboration, automation, exports, support, total cost, and the risk of changing an already qualified workflow.
Yes. Acatian links materials, consumables, labor, utilities, waste, equipment, facility, yield, schedule, and utilization to screening TEA and LCA outputs including COGS, CAPEX, OPEX, cash flow, NPV, IRR, life-cycle inventory, impact categories, ranges, and sensitivities. Supplier quotes, licensed background data, and site-specific evidence remain necessary for decision-grade work.
No. AI can accelerate model assembly, data mapping, documentation, scenario preparation, and review. Engineering calculations should remain deterministic and inspectable, while scale-up, safety, GMP, regulatory, investment, FEED, and FID decisions require appropriate evidence and qualified professional review.
