Tank farm to tanker/ where we intervene
Tank farm to tanker.
Eleven levers, none inside the chemistry.
Raw materials and solvents are stored, reacted in jacketed vessels, separated and recovered in columns, concentrated in evaporators, dried, packed and despatched. jouleWise acts at eleven points — electrical, thermal and data — never inside a validated process.
Green sourcing
Intrastate and ISTS solar and wind contracted through open access for a round-the-clock load.
ElectricityConnectivity and metering
Open access approvals, connection agreement and ABT metering at the incomer.
ElectricityRooftop solar
Solar on warehouse and utility roofs, sized from measured daytime load.
ElectricityBattery storage
Storage to shave peaks, ride through grid events and carry solar into the evening.
ElectricityHeat pumps on jacket loops
Hot water and low-pressure steam to 120 °C for reactor jackets, feed preheating and tank heating, with the boiler kept as back-up.
HeatRecover condenser heat
Chiller condensers and cooling-tower water become the heat pump's source, raising its COP and taking load off the towers.
HeatEvaporation without steam
Mechanical vapour recompression and heat pumps on effluent and product evaporators — the largest steam cut on many sites.
HeatThermal storage
Hot water made in the cheapest electricity hours and drawn by batch campaigns, so heat follows price rather than the shift.
HeatergOS control
15-minute metering of electricity, steam, heat and water; batch and utility scheduling against price.

green electricity.
A chemicals site is a round-the-clock load: agitators, pumps, compressors, chillers and cooling towers never stop. We size the green portfolio to that flat load, and add the heat pumps' demand to it before anything is contracted.
Hover the profile to read any 15-minute block
A chemicals site never stops: agitators, compressors and chillers hold the base up all night. The heat pumps carry jacket hot water and the evaporator round the clock, with batch campaigns in the morning and afternoon and the store charged in solar hours.
Plan
Meter-data due diligence: bills, load survey, rooftop and captive parameters. Solar, wind, hybrid, BESS and exchange electricity optimised together, capex or opex, with each state's ToD, banking and open access charges in the landed-cost model.
Implement
RfP over a 25-year horizon, developer evaluation, reverse auction, PPA and shareholder agreements (26% SPV equity for captive status), open access approvals and connection agreement.
Meter and log
ABT meters at injection and drawal points — main and check meters on CTs and PTs of the required accuracy class — plus data loggers on every incomer, heat pump, steam, fuel and water line. Installed, tested, sealed and linked to the SLDC and to ergOS.
Orchestrate
ergOS forecasts 96 blocks, schedules with the SLDC, trades DAM, GDAM, RTM and GTAM, manages banking and battery health — and now dispatches heat pumps and thermal storage against price.
Heat/ what moves, what stays
Steam where it must be.
Heat pumps everywhere else.
Much chemicals heat is delivered as steam to duties that only need hot water: jackets, preheaters, tank heating, vacuum distillation and evaporation sit between 60 and 120 °C. Atmospheric reboilers, high-temperature reactions and thermal-fluid duties stay where they are.
Heat sources we reuse
Chiller condensers, cooling-tower water, compressor jackets and column overheads — a chemicals site rejects heat all day next to duties that buy it.
Evaporators first
Where effluent or product evaporation runs on steam, mechanical vapour recompression is often the single largest saving — and it is a heat pump.
Sized from metered heat
Portable heat meters log flow and temperature on jacket loops, reboilers and evaporators for two to four weeks before anything is sized.
Economics/ illustrative
Low-cost electricity
drives low-cost heat.
What one kWh of useful process heat costs, and what it emits, depending on where the heat comes from. The heat pump cuts cost on any electricity; green electricity is what cuts the carbon.
Illustrative only, not an offer. Assumptions: PNG ₹55/SCM, 10.4 kWh/SCM, 1.95 kg CO₂/SCM; HSD ₹90/L, 10.0 kWh/L, 2.68 kg CO₂/L; furnace oil ₹62/L, 11.1 kWh/L, 3.15 kg CO₂/L; coal ₹8,000/t, 4,000 kcal/kg, 1.7 kg CO₂/kg, 75% efficiency; boilers otherwise at 85%. Grid 0.716 kg CO₂/kWh; green electricity treated as zero-emission on a market basis with green attributes retired. Heat pump COP 3.5 reflects hot water near 80 °C from a recovered 35–40 °C source; COP falls as delivery temperature rises. All values are replaced with metered site data in the baseline.

In short/ Chemicals
The Chemicals playbook is jouleWise's typical engineering approach for specialty, fine and bulk chemical plants: reactors, columns, evaporators — most of it below 120 °c.
One provider for green electricity, green heat and the data that proves both — from the tank farm to the tanker. For a chemicals producer, carbon has moved from the annual report into the purchase order. Buyers ask for a product carbon footprint, regulators set intensity targets, and the steam bill is still set by fuel prices you do not control. Much chemicals heat is delivered as steam to duties that only need hot water: jackets, preheaters, tank heating, vacuum distillation and evaporation sit between 60 and 120 °C. Atmospheric reboilers, high-temperature reactions and thermal-fluid duties stay where they are.
What to take away
- Heat duties and temperatures: Tank and line heating 40–80 °C (heat pump); Process water and CIP 50–85 °C (heat pump); Reactor jacket heating 60–120 °C (heat pump); Feed preheating 60–110 °C (heat pump); Evaporation and concentration 60–100 °C (heat pump); Vacuum distillation · solvent recovery 80–120 °C (heat pump); Atmospheric distillation reboilers 140–200 °C (stays on fuel); High-temperature reactions 180–300 °C (stays on fuel).
