Objectives

The primary objective of this tender is to solicit quotations for the design, manufacture, and/or supply of a Solid Gas Separation Cyclone (Y1301) in accordance with the attached specification sheet. The aim is to procure a cyclone that effectively captures entrained solids from process gases generated during plasma gasification of uranium-contaminated waste oil, ensuring operational efficiency and compliance with technical requirements.

Scope

The scope of work includes:

• Supply of one (1) Solid Gas Separation Cyclone (Y1301) as per the attached Specification Sheet.
• Provision of all necessary labour, materials, and services for sizing, selection, design, manufacturing, and delivery to Necsa in Pelindaba.
• Inclusion of all accessories required for the cyclone's operation.
• Options for either the design and manufacture of a new cyclone (Option A) or supply of an off-the-shelf product (Option B), with relevant documentation for evaluation.

Note: All other equipment referenced in the P&ID or specifications outside the scope are not included.

Technical Requirements

The cyclone must meet the following technical specifications:

• Operate with a maximum gas throughput of 57.9 kg/h (~71.6 m³/h) at an inlet temperature of 90°C and pressure of -7.9 kPa(g).
• Handle process gases comprising CO₂, H₂O, HF, HCl, O₂, and N₂, with entrained solids including triuranium octoxide and metal oxides, with particle sizes ranging from 1 μm to 3 μm.
• Incorporate a flange for solid removal from the cyclone's solid particulate matter.
• Be capable of continuous operation for up to 8 hours, with provisions for solids removal via a rotary valve into a collection drum.
• Design must ensure the cyclone operates in conjunction with a solids collection drum and optionally with a downstream knockout catch pot V1304.
• Include all accessories, such as filters and sampling systems, as specified in the attached P&ID.

Skills Requirements

The successful bidder must demonstrate:

• ISO 9001:2015 accreditation or equivalent certification, with evidence provided.
• Capability to supply off-the-shelf cyclones within specified lead times (4-8 weeks) or demonstrate the ability to design and manufacture a cyclone that meets all specifications.
• Experience in designing and manufacturing cyclones for hazardous and radioactive process gases, ensuring safety and compliance.
• Proven after-sales service, including maintenance and repair capabilities, supported by relevant documentation or references.
• Technical expertise in handling materials and operating conditions similar to those specified, including handling entrained solids and process gases in nuclear-related applications.
