VISCOSE & CARBON DISULFIDE CS2 COMPLEX

viscose staple fibre rayon filament complete equipment

1.      Scope of supply

Taking linter pulp and wood pulp as main raw material, the production plant with a production capacity of 30kt/a viscose staple fibre, including the process equipment and piping materials (without heat insulation materials), instrumentation, electricity, air conditioning equipment and spare parts for the four workshops of dope (including lye station), spinning and after treatment, acid station and carbon disulfide preparation.

The civil, lighting, fire fighting, domestic water supply and drainage for the workshops are not included in the scope of offer.

Utility facilities are not included in the scope of offer.

The plot plan and the aboveground and underground piping in the plant site are not included in the scope of offer.

  1. The scope of obligations

The engineering design for the above mentioned four workshops: the procurement and transportation (FOB) of equipment and materials, technical training, technical service, start up and performance guarantee.

Not included in the present offer are geological survey, civil works and the erection work (and erection materials) for equipment, piping, insulation, instrument, electricity and air conditioning, etc.

3. Battery limit

The battery limit is an imaginary boundary which ends one meter outside the unit or building.

For electricity, the battery limit starts from the output terminal of low voltage distribution panel.

The connection point for incoming utility piping (including water drainage pipeline) entering into the battery limit from underground is 0.5 meter above ground level.
