Tejomaya is a company who is working in Agriculture domain with energy solutions. Tejomaya is convinced with the technology developed by CSIR-CIMAP seed technology and as well as extraction of the extraction of essential oil from various grasses using a patented distillation process. The essential oil is used in most of all sector producing cosmetic products, medicated products, and perfumes. CSIR- Central Institute of Medicinal and Aromatic Plants, Government of India, popularly known as CIMAP, is a frontier plant research laboratory of Council of Scientific and Industrial Research (CSIR). Established originally as Central Indian Medicinal Plants Organization (CIMPO) in 1959, CIMAP is steering multidisciplinary high-quality research in biological and chemical sciences and extending technologies and services to the farmers and entrepreneurs of medicinal and aromatic plants (MAPs) with its research headquarter at Lucknow.

CSIR-CIMAP after long research they developed seeds of various grasses like lemongrass, Mint, Rose, Lavender, Geranium, Palmarosa, Java etc which contain more percentage of essential oil in it as compared to traditional available. Also, they developed patented essential oil extraction process through distillation which required Heat energy for extraction of oil from the various grass. Currently, they are using wood as a primary source for heat generation to heat the water at 95 degrees which is causing a lot of pollution in the environment as well as the force to cut the trees. Instead of wood Green life Proposed CPC system for heat exchange as heat requirement is only below 95 degrees and hence can easily extract the essential oil without burning.

Executive summary

As we all know India has been blessed with tremendous renewable energy potential. Solar energy is everywhere, it’s abundant and we’ll practically never run out. Even in mid-winter, we are blessed with a moderate amount of natural daylight provided courtesy of the sun. It might not be sunny every day but we are still experiencing radiation from the sun and it is this which can be gleaned for our own renewable energy purposes. Thus the need for finding a long-lasting energy resource is over.

ABOUT COMPOUND PARABOLIC COLLECTOR (CPC)

CPC Design Concepts – An interesting design for a concentrating collector makes use of the fact that when the rim of a parabola is tilted toward the sun, the rays are no longer concentrated to a point, but are all reflected somewhere below the focus.   The rays striking the half of the parabola which is now tilted away from the sun are reflected somewhere above the focus. This can be seen in the Figure where the rays on the right-hand side are reflecting below the focus and the rays on the left-hand side are reflecting above the focus. If the half parabola tilted away from the sun is discarded, and replaced with a similarly shaped parabola with its rim pointed toward the sun, we have a concentrator that reflects (i.e. traps) all incoming rays to a region below the focal point.

Since the rays are no longer concentrated to a single point, this design is called a non-imaging concentrator.  A receiver is now placed in the region below the focus and we have a concentrator that will ´trap´ sun rays coming from any angle between the focal line of the two parabola segments.  Receivers can be flat plates at the base of the intersection of the two parabolas, or a cylindrical tube passing through the region below the focus. The basic shape of the compound parabolic concentrator (CPC) is illustrated in Figure below.

Current SETUP

As CSIR-CIMAP after long research they developed seeds of various grasses like lemon grass, Mint, Rose, Levendor, Jirenium, Pamarosa, Java etc which contain more percentage of essential oil in it as compare to traditional available. Also they developed patented essential oil extraction process through distillation which required Heat energy for extraction of oil from various grass. Currently, they are using wood as a primary source for heat generation which is causing lot of pollution in environment as well as force to cut the trees. Instead of wood Green life Proposed CPC system for heat exchange as heat requirement is only 95 degree and hence can easily extract the essential oil without burning.

 

Existing Arrangement Wood fired Boiler
Heat required in form of Hot water
Water Temperature 95 degree hot water
Working Timing 9:30 am to 4:00 PM
Total Energy required 1500000 Kcal per day
Required temperature 95 degree
Present Fuel (wood) Consumption Up to 600 Kg per day

PROPOSED CPC Setup

After the survey green Life team find that we need to not disturb their existing setup, instead we can provide energy from our CPC system to extra the essential oil instead of burning of wood.

Below is the proposed solution for their existing setup to convert it on solar.

   
Total Solar Thermal Area require 720SqMtrs
Heat required for application 95 degree
Proposed System Thermic Oil based
Heat provided in form of Hot Oil
Integrated with Existing System Yes
New system will be integrated No
Updating of existing piping Yes
Area Required for CPC Installation 1125sqmtrs
Ground Shadow free area available 2500sqmtrs
CST Type CPC Collectors
Storage Not Applicable
Components Solar CPC collectors

Pump& Valves

Thermic Fluid

Piping and Insulation

 

PROPOSED SCHEMATIC DIAGRAM

Total 720sqmts of Compound Parabolic Collector (CPC) solar thermal field will be installed which will help in collecting thermal energy in the form of thermic oil. We rotate the thermic oil through the CPC installed at. With every rotation, oil will gain temperature and same will be utilized by the user in its process heating application to heat water at the required temperature and extract the essential oil from the grass at a controlled temperature as shown in the above diagram.

MOU

As per preliminary discussion, the user is ready for signing the MOU for the agreed contract period and to install the solar CPC system after sanctioning from MNRE

Detail of investment made by each party

Total System cost  Rs. 10980000.00
MNRE Subsidy Rs. 2587500.00
User Contribution Rs. 2196000.00
Green Life Contribution Rs. 6196500.00

Monthly recurring benefits to both parties

 

Considerations

  1. 280 Sunny days in a year
  2. Wood Cost Rs.7.60 per Kg

Per day Energy Generation                     1500000 Kcal

Per Day Wood Savings                             600 KG

Yearly Saving on Wood                            600 x 280 = 168000Kg

Yearly Monetary saving                              168000Kg  xRs. 7.60 = Rs1276800.00

Other expenses                                            Rs. 210000 /-

Tot. Savings                                                     Rs 1486800/- per year

Recurring Charges to User                           Rs1040760.00 (ESCO)   &Rs. 446040.00beneficiary
(70% ESCO – 30% Beneficiary from Saving)

Contract Period                                            7 years

User saving in 7 years                                  Rs3122280.00 + System (Rs. 10980000.00)

Rs14102280.00/-

 

 

Note: Above Calculations are based on today’s Wood cost. If in future Wood cost increase the benefit and recurring charges may also increase in the same proportionate.


Agreement Time period

Agreement period shall be for 7 years. Till the agreement period it will be solely Green Life responsibility to maintain the system. And at the end of the contract period Green life shall hand over the system to the user in running condition.

At the end of the contract period User and Green Life mutual may decide to extend the contract period on revised financial terms.
