Design basis
Confirm feed and upset analyses, target limits, flow range, solids loading, droplet size, dissolved species, temperature, pressure, chemical compatibility and disposal or regeneration route.
Water & Process Treatment · ENGINEERED SCOPE
Process Stream Polishing Packages
Polishing packages provide the final contaminant-removal step required to meet a defined water, hydrocarbon or gas specification. The treatment mechanism is selected from measured feed contaminants rather than from a generic package arrangement.
Engineering approach
Process Stream Polishing Packages
A technically defined package begins with the operating envelope—not a catalogue model.
Rated capacity, minimum stable load, feed envelope, inlet and outlet conditions, product specification, start-up and shutdown cases, design life and acceptance criteria are agreed before equipment definition is frozen. Package basis also fixes battery limits, skid envelope, lifting and shipping constraints, utility tie-ins, FAT scope, preservation requirements and commissioning deliverables.
Process configuration
Possible stages include cartridge or depth filtration, coalescing, activated carbon, guard media, ion exchange, adsorption, membrane treatment and chemical conditioning. Duty, redundancy and media-change access are coordinated with operations.
Verification focus
The guarantee basis covers influent envelope, effluent specification, differential-pressure limit, media life assumptions, breakthrough monitoring, turndown, bypass prevention and safe spent-media handling.
PROJECT DEFINITION · DELIVERY
Clear inputs, auditable outputs
Technical proposal quality depends on verified process data, acceptance criteria and interface definition. The following information is confirmed during clarification.
RFQ information
- “Feed and outlet specification”: Record feed phase/composition, relevant contaminants, water/solids/salts/hydrocarbons, product/effluent targets and pressure-drop limit.
- “Technology and process arrangement”: Select separation/treatment method, stages/internals, chemicals/adsorbent, filtration and standby options from feed analysis.
- Site utilities, ambient data, hazardous-area classification and battery limits
- Required performance guarantee, redundancy and availability philosophy
- Applicable project codes, materials, inspection requirements and document format
Engineering deliverables
- Equipment datasheet and design basis for “Process Stream Polishing Packages”, with service-relevant calculations where included in the supply scope.
- Heat and material balance, PFDs, P&IDs and utility summary
- Equipment datasheets, line and instrument lists, control narrative and cause-and-effect inputs
- Layout, nozzle and interface data, foundation loads and maintainability review
- Inspection and test plan, FAT documentation, manuals and final manufacturing record
RFQ
Discuss this duty with engineering
Share the operating cases, feed data and required guarantee so the applicable process route, package boundary and verification plan can be defined.
Technical Datasheet
Technical Datasheet — Process Stream Polishing Packages
A specific process-gas adsorption polishing unit from a public project specification is shown as an engineering example, not as a general polishing-package range or Delham guarantee.
| Parameter | Published design point | Basis / secondary data | Application limit |
|---|---|---|---|
| Adsorber feed flow | Up to 1,000 SCMD | Published process specification for one process-gas adsorption unit. | Small slipstream design point; feed composition and adsorbent-cycle balance determine actual capacity. |
| Adsorber design conditions | 20 kgf/cm² design pressure; equipment exposed to about 300 °C | Conditions from the same project specification. | These are project design conditions, not operating targets or standard limits for polishing packages. |
