Set of Programs and Trainers for Instruction of Chemistry Personnel
of Fossil and Nuclear Power Plants
The set of programs for instruction, training, and re-training of chemistry
personnel at power plants on efficient, failure-proof, and ecology-free
operation of water treatment facilities has been developed at TWT Department
under supervision of Dr., Ass. Professor Valery
F.Ochkov ochkov@twt.mpei.ac.ru
.
This set includes electronic manuals and trainers.
The following trainers are available:
- Liming and Coagulation of Water in Clarifiers
(WINDOWS)
- Removal of Coarse Impurities with Single
-Chamber Mechanical Columns (DOS)
- Removal of Coarse Impurities with Two
-Chamber Mechanical Columns (DOS)
- Removal of Coarse Impurities with Three
-Chamber Mechanical Columns (DOS)
- Softening of Water with One-Stage Na-Cation
Exchangers (WINDOWS)
- Softening of Water with Two-Stage Na-Cation
Exchangers (WINDOWS)
- Water Demineralization with the Primary Concurrent
Hydrogen Cycle Cation Exchangers (DOS)
- Water Demineralization with the Primary Countercurrent
Hydrogen Cycle Cation Exchangers (DOS)
- Water Demineralization with the Primary Concurrent
Hydrogen Cycle Cation Exchangers - Prefilters and Main Filters (DOS)
- Water Demineralization with the Secondary
Hydrogen Cycle Cation Exchangers (DOS)
- Water Demineralization with the Primary Hydroxide
Cycle Anion Exchangers (DOS)
- Water Demineralization with the Secondary
Hydroxide Cycle Anion Exchangers (DOS)
- Water Demineralization with Mixed Bed Exchangers
with Internal Regeneration (DOS)
- Condensate Polishing with the Sulfonated
Coal Columns and Mixed Bed Exchangers with External Regeneration
- Condensate Polishing Unit (WINDOWS)
- Water Treatment with Magnetic Filters
- Treatment of Oily Wastewater with Mechanical
Columns (WINDOWS)
The trainers simulate the basic stages of operation of water treatment
equipment: rinse of filters prior to service, filtration, backwash, separation
of resins, regeneration, rinse after regeneration, filter in operation
or stand-by etc. Color diagrams are displayed.
They show (a): current state of ion exchangers and other equipment:
opening of valves, turning on of pumps, flow of water and regenerants,
change of resin state (backwash, shift of filtration/regeneration level,
, separation of resins);
(b): readings of instruments (flowmeters, manometers, conductivity meters,
concentration meters, level indicators etc.);(c) sampling etc. Some processes
(ion exchange mechanism, for example), are illustrated with multimedia
(animation and sound). It is possible to simulate water treatment operation
manipulating with mouse or keyboard: to open/close valves, to sample water,
to monitor instrument readings etc.
All mistakes made by the student (incorrect diagram arrangement, violation
of process chart, overexpenditure of chemicals and auxiliary water etc.)
are recorded. This gives the instructor information if the student can
operate field chemistry equipment at power plant by his/her own.
The following DOS electronic manuals are available:
- Makeup Treatment at Fossil Power Plants with
Ion Exchange (parts 1 and 2)
- Thermal Desalination and Waste Treatment
- Water Clarification with Filtration
- Water Pretreatment with Liming and Coagulation
- The Basis of Hydraulics, Piping, Valves,
and Pumps of Chemistry Departments
- Removal of Soluble Gases from Water
- Neutralization of Demineralization Wastewaters
- Neutralization of Oily Wastewaters at Fossil
Power Plants and Industrial Enterprises
- Solid Fuel Monitoring at Fossil Power Plants
and Industrial Boiler Rooms
- Automation of Water Treatment Facilities
System requirements: PC with at least 286 processor for DOS versions
and PC with at least 386 processor for WINDOWS versions.
Besides, a set of special software - TWTServer - has been developed
at this department. It gives the chemistry personnel at power plants and
training centers the opportunity to develop trainers on their own, with
account for specific equipment.

Please contact us, and you will receive the set of software with detailed
operating manual and invoice, which you will pay, if this set suits you
in your work with water treatment personnel.

Cycle Chemistry
at Fossil and Nuclear Power Plants
The studies aimed to improve cycle chemistry at
power plants have been underway at TWT Department. They are headed by Dr.
Prof. Olga
Martynova and Dr., Leading Researcher
Tamara
Petrova. In particular, the research
on behavior of organic impurities in the power plant cycle is continuing.
This problem is very acute at present. The data on distribution ratios
of organic compounds - acetic and formic acids - between boiling water
and equilibrium saturated steam have been obtained; a correlation between
level of acetic acid in water and chloride distribution ratio has been
established. These studies are performed at test rigs operating at high
temperatures and pressures.
At present TWT Department and Scientific and Training
Centre of Geothermal Energy (STS Geo) do a joint research work under agreement
with Electric Power Research Institute (EPRI), USA, to improve turbine
steam chemistry.
One of the tasks of the utility personnel is to
minimize downtime corrosion failures of equipment. TWT Department implements
one of filming (octadecylamine-base) amine for equipment layup at power
plants. This method of equipment protection from downtime corrosion have
been introduced numerously at different types of equipment, including 800
MW units: Mosenergo Power Plant NN 22 and 23, Litovskaya GRES, several
power plants in Yugoslavia etc.
TWT Department has up-to-date instruments to determine
low levels (1-2 ppb) of impurities (among them chloride, sulfate, phosphate,
nitrate, nitrite, acetate (anion of acetic acid), formate (anion of formic
acid), oxalate, ammonia, potassium, sodium, iron, copper etc.) in water
and steam (ion chromatograph DIONEX (USA), atomic absorption spectrophotometer
AAS-3 (Germany) etc.). There is also Orion on-line sodium analyzer (USA)
to determine low ( down to 0.5 ppb) sodium levels in water and steam.
