Chemical & Pharma Solution
Convert Process Waste Heat into Reliable Clean Power.
Recover low and medium-temperature waste heat from boilers, thermal oil heaters, distillation columns, reactors, dryers, evaporators, and incinerators to generate captive electricity.
Executive Summary
Unlocking value from chemical & pharma process streams.
Chemical and pharmaceutical manufacturing depends on continuous thermal processes such as distillation, reactors, evaporation, drying, and steam generation. These operations produce significant amounts of waste heat that is often released through flue gases, process exhaust, thermal oil systems, and cooling streams.
This unused thermal energy can be converted into clean power.
At Datre Renewable Energy, we help chemical and pharmaceutical manufacturers maximize energy efficiency by converting waste heat into reliable power using Organic Rankine Cycle (ORC) technology—reducing operating costs, improving sustainability, and increasing overall plant performance.
Heat Source Mapping
Where Does Your Plant Lose Energy?
Throughout chemical and pharmaceutical production, valuable thermal energy is continuously discharged from multiple process units.
| Process Area | Typical Heat Source | Temperature Range |
|---|---|---|
| Steam Boilers | Flue Gas | 180–300°C |
| Thermal Oil Heaters | Exhaust Gas | 250–400°C |
| Distillation Columns | Overhead Vapours & Condensers | 150–250°C |
| Reactors | Process Heat & Exhaust | 150–350°C |
| Dryers & Evaporators | Hot Exhaust Air | 150–250°C |
| Incinerators | Flue Gas | 300–600°C |
Disclaimer: The temperatures, recovery potential, and energy estimates presented on this page represent typical industry values and are provided for illustrative purposes only. Actual recoverable energy depends on plant design, operating conditions, production capacity, heat source characteristics, and overall system configuration. A detailed engineering assessment is recommended to determine the feasibility and performance of an Organic Rankine Cycle (ORC) system for your facility.
Did you know?
Many chemical and pharmaceutical facilities can lose 20–35% of their thermal energy as waste heat, depending on process design, operating conditions, and heat recovery systems already in place.
Operating Impact
What Does This Mean for Your Plant?
Every production cycle generates thermal energy that often leaves the facility without providing any additional value.
Higher Electricity Costs
Continuous process operations inflate monthly grid power bills and energy expenses.
Increased Fuel Consumption
Unrecovered process heat forces higher fuel use in boilers and thermal oil heaters.
Lower Process Efficiency
Discharged vapours and flue gas degrade overall facility energy utilization balance.
Greater Carbon Emissions
Relying solely on fossil-grid electricity inflates environmental carbon footprint.
Missed Energy Recovery
Free, accessible thermal streams bypass captive power generation opportunities.
Output & Financial ROI
Typical Energy Recovery Potential
Datre manufactures standard 10 kW, 50 kW, and 500 kW ORC systems that scale modularly for chemical and pharmaceutical facilities of any capacity.
| Process Heat Stream | Power Output |
|---|---|
| Small Pharma Unit / Dryer Exhaust | 10 kW – 50 kW |
| Specialty Chemical / Reactor & Distillation Stream | 50 kW – 500 kW |
| Bulk Chemical Plant / Thermal Oil Flue | 500 kW |
| Integrated Chemical & Pharma Complex | 500 kW – 3 MW+ |
Imagine the Value for a 500 kW System
Suppose a 500 kW Datre ORC System operates 8,000 hours per year, generating approximately 4,000,000 kWh (40 Lakh units) of electricity annually.
If industrial grid electricity costs average ₹7–9 per kWh, the generated captive power represents:
Instead of relying entirely on purchased electricity, your chemical facility can convert waste heat into reliable electricity using modular Datre 10 kW, 50 kW, and 500 kW ORC units to significantly reduce operating costs.

- Fully automatic operation — Unattended, self-regulating closed loop
- High operational reliability — Engineered for continuous chemical plant operation
- Low maintenance requirements — Non-corrosive, non-eroding working fluid
- Suitable for continuous processes — Operates seamlessly alongside reactors & distillation
- Long equipment life — Proven 20+ year lifecycle with stable performance
