Chemistry Technology Monitoring Systems
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.
For more information please download the demo version: ftp://twt.mpei.ac.ru/demo.vpu/
If you are interested in this software, please contact:
V.F. Ochkov, TWT Department, Moscow Power Engineering Institute, 14 Krasnokazarmennaya, Moscow, 111250, Russia tel./fax 095-362-7171, e-mail ochkov@twt.mpei.ac.ru.
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.
