In subcontract to the licensor, i.e. Proserpine Sugar Mill (PCSMA), DalinYebo provided the following services:
Evaluation of a furfural and furfuryl alcohol project:
Evaluation of the performance of the SupraYield pilot plant studies and its scale-up.
- Reaction kinetics: Conversion of pentosans to furfural.
- General operating parameters, including charging sequences in to the digesters.
- Typical energy and mass balance, which will provide data, such as:
- Typical yields of FF and FA yields per ton of bagasse.
- Expected production costs
- Typical consumptions of steam, water, power, acid, lime, etc. per ton of product (FF or FA).
- Expected effluent generation and loading.
- Suggested equipment list (Feedstock intake to FF or FA dispatch and utilities).
- Typical electrical and instrumentation requirements.
- Typical site layout (plot plan).
- Preparation of bagasse: Storage, conveying and drying.
- Suggested methodology for treatment and disposal of solid, liquid and gaseous wastes.
- Organisation chart with suggested manpower requirement, including managerial, supervisory, skilled & unskilled labour in an organization chart.
- Preliminary program (time schedule), detailing principal activities.
Facilitation of the license agreement between Proserpine Sugar Mill and Arcoy.
Development of the process design package
The Process Design Package was based on the Plant that PCSMA was building at Proserpine. PCSMA made design information available to facilitate a carbon copy of their design, provided that such information is the property of PCSMA. In broad terms, the information was consistent with data and information developped by PCSMA to safely operate and maintain a plant.
- Description of Technology
- Description of Plant operation, incl. OBL requirements
- Operation and control philosophy
Preliminary Mass and Enthalpy Balance for Arcoy plant
including datasheets, which give either performance specifications (e.g. conveyors) or sizes and capacities (e.g. tanks) for each piece equipment:
- Material of construction specifications
- Civil/Structural: Preliminary plant layout and elevation for the Plant
- Loading for major equipment
- Electrical: Single Line Diagram
- Instrumentation list, incl. preliminary loop count
- Reactor Design
General Arrangement of Reactor
complete with filling and catalyst addition device, excluding any ancillary equipment, such as the automatic door, which is a bought-out item. The design will be to Australian Standard AS1210 and the Licensee will be responsible to undertake what ever work is necessary for the Reactor Design to be in compliance with the statutory and legal requirements of the Territory, i.e. he local fabricators in India have to develop their own fabrication drawings, based on the following Vessel & Drive System GA:

- Non-drive Side Roller Base Frame Details
- Inlet Nozzle & Alphorn Details
- Vessel & Drive System Drive Base Details
Description of Datasheet Types
Conveyors: Datasheet specifying length, capacity, bulk density, belt material, dust handling, etc. enabling them to be designed and built by local sugar equipment suppliers using local standards for pulleys, guards, emergency stops etc
Tanks, Vessels, Drums: Datasheet giving volume, diameter, height, outline sketch, MoC, wall thickness and nozzle schedule. Fabrication drawings will be made available where possible
Pumps: Datasheet with pump type, head, capacity, fluid specs, MoC, seal arrangement, electrical enclosure spec.
The contract was completed with the handover of the process design package.
In February 2012, DalinYebo was awareded a contracted by Arcoy to commission the steam stripping system addition.
2008 - 2009 and 2012
