ASHEngineering Design Suite

Process· Release 2.68

Process design software for mass balance and heat exchangers.

The Process Design Bench covers flowsheet mass balance with recycles, heat exchangers, separators, tanks and venting, dosing, activated sludge and clarifiers, filters, RO and membranes, cooling water, steam and gas compression, and concept treatment trains.

What it covers

From the flowsheet to the unit.

Concept, detailed design and design verification run on the same engines.

Flowsheet mass balance

Flowsheet mass balance with recycles; concept treatment trains.

Heat exchangers

Energy balance across hot and cold side, LMTD with the F correction, U from the service table — duty and area required beside the area provided.

Separators, tanks & venting

Separators, tanks and venting.

Dosing & treatment

Dosing, activated sludge and clarifiers, filters, RO and membranes.

Utilities

Cooling water, steam and gas compression.

Inside the bench

A heat exchanger duty check.

Stages

Concept, detailed design, verification — the same engines throughout.

A concept scheme, the detailed design and the reviewer's check are run by the same code, so they never disagree with each other. Choose the stage when a project starts; develop a concept into the detailed design in one click.

1 · Concept design

From a few inputs to a sized scheme

  • Floor areas, occupancy, grid, flows, population
  • Plant sizes, member sizes, main feeders, storage, quantities
  • For options, budgets and early coordination
2 · Detailed design

Every element, every check

  • Element-by-element sizing with code checks and clause references
  • Diagrams, schedules, single-line and riser diagrams, SVG export
  • Calculation report for submission; Excel and CSV schedules
3 · Design verification

Independent check of a design by others

  • Submitted values beside the calculated ones
  • Review codes A / B / C with the clause; CRS comment rows
  • Rev.xx resubmission cycles; value-engineering opportunities
Questions
Which codes and standards do the benches use?

The Saudi Building Code set (SBC 201, 301, 304 and 801) and the Saudi Civil Defence regulations, ACI 318 and ASCE 7, AISC 360-22, the International Codes (IBC, IPC, IMC, IFC), NFPA 13, 14, 20, 72, 92, 101 and 2001, NEC and IEC 60364 / 60909 for electrical, IEEE 1584 for arc flash, ASHRAE Fundamentals for HVAC, ASME B31.3, API 520, ISO 5167 and IEC 61511 for piping and instruments, IEC 62676-4 for CCTV, and QCS 2014 with the Qatar Civil Defence guidelines among others. Every check names its clause, and each requirement pack states the edition it quotes.

Does it replace finite-element or building-energy software?

No. The benches cover the member, system and network calculations of everyday design and review — frames, feeders, ducts, networks, sprinkler areas — with the transparency a reviewer needs. Whole-building finite-element models and detailed hourly energy simulation stay with their specialist tools; the benches sit beside them and check what they produce.

Is my project data sent anywhere?

Your project never leaves your computer: the benches and ELDAS keep projects in the browser and in the files you save. The pages serve their own fonts; the trial applications still load their web fonts from Google Fonts. See the privacy notice.
