)We're inviting to submit an offer for the installation of the Graphitization Fumes Treatment Installation

Technical contact person:Marcin Ujwary, +48 18 4425-336, +48 695745036, Marcin.Ujwary@tokaicobex.com the service applies to the plant in Nowy Sącz/Poland.

Scope of inquiry:

the full scope of the query is in the file "Graphitization Fumes Treatment Installation - Inquire ver2". An overview is given below:

- Actual Graphitization Fumes Treatment Installation:

Currently, for fumes treatment we use two-stage system consisting Regenerative Catalytic Oxidizer (RCO) installation and wet (twoalcalic) DeSOxunit.

Because of the age installation has greater failure rate hence more expensive in maintenance and service.

Total fumes consist of gases from three sources:

1.Gases from the graphitization run (charge), which are directed to the RCO and then to the DeSOx and to the stack.

2.Gases from the graphitization cooling process that are directed straight to the DeSOx and to the stack.

3.Gases from the graphitization packing media suction, which are also directed straight to the DeSOx and to the stack.

- New preferred Graphitization Fumes Treatment Installation- scope

Main objective of the project is to build energy efficient Graphitization Fumes Treatment Installation for graphitization in Nowy Sącz plant according to given emission limits.

New construction need to be done "in vivo" as existing system runs with full capacity utilization and big disturbance in process are not possible.

Treated gases needs to be directed to existing stack.

Preferred solution is to implement DeSOx system with Regenerative Thermal Oxidizer (RTOs).

- Project needs to be defined in phases if possible (DeSOx first, RTO second).

- Have to be specify utilities consumption for complete system.

- Integration with existing control system Scada (ASIX)

- Specify battery limits for exhaust gases– flanges outside Graphitization building.

- Specify battery limits for utility. Have to be located at one point in area of projectrealization.

- Completede sign of all branches (Civil,Technology,IT,Automation,etc.) on Supplier side.

- All ground works, for example foundations, on Supplier side.

- New installation have to be connected parallelly to existing DeSOx installation as a backup.

- Consider to put all necessary tanks under ground as a concrete tanks.

- Consider to have redundant main fans and main pumps.

- Consider to use a container buildings, it means all noisy and not-outside preferable equipment to install in containers. All electric, automation, IT equipment also install in containers -Installation RTO and DeSOx have to allow to direct Graphitization fumes (Charge, Cooling, Packing Media Suction) in all configurations shown on layout (page 8). All equipment necessary to arise complete RTO and DeSOx installationis on Supplier side (e.g. cranes, lifts, scaffolders, etc.)

- Disassembly of needless fumes installation (pipes, pillars, supporting construction, etc.) and transport it to agreed place on Supplier side (metal and other scrap management based on general conditions)

- Presence on Hazop required ( 2 days).

- New RTO expectations:

- RTO with all pipes have to be isolated.

- Fumes pipes have to be traced.

- Compressed air pipes made by stainless steel.

- Hydrated lime expected consumption per year.

- Potential wastes generated during treatment process–type, amount per year.

- Burnout process with sulphate ammonium removal

- Corrosion resistant materials/technology

- Technical availability 100 %

- During design we specify battery limits and there will be measured fumes temperature.

- New DeSOx expectation:

- One or two DeSOx units depending on the required capacity.

- NaOH sorbent method

- Units redundancy at least 75 %

- Compressed air pipes made by stainless steel.

- Potentially exposed on acid/corrosion steel elements have to be made of stainless steel.

- Potential wastes generated during treatment process– type, amount per year.

- NaOH expected consumption per year.

- Because of presence dust/ particles/ condensate in Graphitization fumes, a desludging systemis required.

UPDATE OF SCOPE 30.11.2020: 

All documentation and screens of a new equipment RTO and DeSOx, for example Scada and HMI screen have to be translated in to the Polish language.

UPDATE OF SCOPE 15.12.2020:

Attached picture (Location of RTO&DeSOx) shows preferred by us location of DeSOx and RTO installation.

RTO could be placed were is using RCO installation.

RCO will be disassembly for time necessary to build RTO.
