Mechanical Vapour Recompressors (MVR) Process
Learn About MVR Processes
MECHANICAL VAPOR RE-COMPRESSOR
Are you Struggling in your Multi
Effect Evaporator?
- Are you fed up with high consumption of steam?
- High Cost of Boiler Operation?
- High Maintaince Cost of Auxillary Pumps?
- Mixing of Steam with Process Fluids?
- Secondary treatment of condensed steam effluent generated?
- Large footprint of Installation?
- Low flexibilty in operation?
- High manpower deployment for operation and thus high operating cost?
Most Common Mistake designers make while selecting the Product/Technology !!!
- Overlooking the long term Operating Cost
- Overlooking the Overall Energy Consumption
- Overlooking the Oerall Footprint of the Equiptment
- Focus on Capex Cost and Not Total Cost of Ownership
- Wrong Material Selection while choosing an MVR supplier
I- ncorrect sealing mechanism for MVR leading to frequent failures.
8 Benefits of Adopting to MVR/MVC technology by Everest
- Reduction in Steam Consumption by upto 85%. MVR uses electrical energy to re-compress the evaporated vapours and resend these vapours back into the evaporator to evaporate another mass of liquid.
- Instantaneous Start/Stop Option since it is a mechanically driven machine, process tabilization is much faster.
- Low Specific Power Consumption befoce of high volumetric efficiency leading to high overall Coeeficient of Performance of upto 9.
- Redcued footpring as a compact high speed machine is installed which can cater to multiple effects.
- Special Alloy MOC for all wettet parts to deliver even in the most harsh conditions.
- Special Tripple Sealing Mechanism (Patent A/F) to prevent any process material contamination to Oil and thus enhancing the product life drastically.
- Reliable design and strong service and part support gurantee best in class uptime gurantee.
7 Differentiating benefits that our customers GET from EVEREST MVR !!!
- Alloy Steel Construction with special plating on wetted parts leading to prolonged pump life
- Tripple Sealing (Patent A/F) ensures no process material contamination with lubricating oil, thus making the machine an Oil Free Design.
- No Process Fluid Contamination with Water or any other sealing fluid. More than 90% process fluid recoery for reuse.
- Reduced Load on Colling Tower and Boiler by upto 85%, the heat generated is being consumed within the system itself.
- High Volumetric Efficiency ensures that machine operates at a High CoP of about 9 giving excellent operating economics to customers and reducing there OPEX by almost 50% as compared to TVR technology.
- High Volumetric Efficiency, High Displacement & High Delta P machines designed specifically for MVR operation along with enhanced sealing and metturlgy ensures long term trouble free operation.
- Ready Spare Parts availibilty and Economically proced spares ensures low cost of maintance as bencmarked to competetiors.
Below is a Table for cost benefit anaylysis of using MVR over TVR and how an MVR can save substantial cost for the customer and payback period. Following presumptions have been made to facilitate calculations.
| Steam Cost - Rs./Kg | Power Cost (Rs./KW) | CW Cost (Rs/m3) |
|---|---|---|
| 2.5 | 6 | 2 |
| Hrs. of Operation/Day | No. of Days/Operation | |
| Tripple Effect Evaporator with TVR | Single Effect Evaporator with MVR | |
| 20 | 300 | |
| Steam Consumption | 600 Kg/hr | 300Kg/Hr - First 3 Hrs to Stabilise |
| CW Consumption | 55m3/hr | 30m3/hr |
| Power Requirment | 70HP/52KW | 215HP/160KW |
| Steam Cost (Rs.) | 90,00,000.00 | 6,75,000.00 |
| CW Cost (Rs.) | 6,60,000.00 | 3,60,000.00 |
| Power Cost (Rs.) | 18,72,000.00 | 57,60,000.00 |
| Total Cost (Rs.) | 1,15,32,000.00 | 67,95,000.00 |
| Total Savings (Rs.) | 47,37,000.00 |
Therefore in a typical such replacement the customer can save upto ₹ 47.37 lacs in Operating Cost. Even if we factor the cost of Capital Equiptment (Replacement) to be around ₹ 35 lakhs, the payback of MVR over TVR is still coming within a payback of 10 months. All savings beyound this period will directly add to the bottomline.

TESTIMONIALS
Everest Vacuum is a leading vacuum systems solution provider with great after sales service & support, they have done brilliantly well in understanding our
complete product & process requirement, designed a customised solution for us & supported us in commissioning of the product in the right fashion. We had to upgrade our installations from Stem/Water Jet ejectors to Dry Screw Vacuum Pumps looking into the enormous advantages that it would offer in terms of consistent deep vacuum & environmental friendly technology. We are very glad that we dealt with such a company who demonstrated high standards of professionalism along without losing sight of customer requirements. We would like to work with them again in the future & wish them all the best.
