Heating And Cooling Solutions

Heating and Cooling Solutions

Overview

Heating and Cooling Solutions are critical process systems used to control fluid temperature in oil & gas, refinery, power generation, LNG/LPG, and industrial facilities. Temperature control directly impacts​​ process stability, phase behavior, hydrate formation, corrosion risk, energy efficiency, safety, and equipment life.

Mechasol designs and manufactures​​ engineered heating and cooling systems​​ that are fully integrated into process packages such as​​ PRMS, gas conditioning units, well stream facilities, refinery process units, LNG systems, and power plant fuel gas trains.

All Mechasol heating and cooling solutions are engineered as​​ process-driven systems, not standalone heaters or exchangers, ensuring reliable operation across varying flow rates, pressures, and ambient conditions.

Role of Heating & Cooling in Process Systems

Heating and cooling systems are applied to:

• Prevent hydrate and condensation formation

• Compensate for Joule–Thomson cooling during pressure reduction

• Enable phase separation and liquid recovery

• Control gas and liquid viscosity

• Protect downstream equipment (meters, turbines, compressors)

• Improve combustion efficiency and emission control

• Recover and reuse waste energy

Indirect Fired Water Bath Heaters

Indirect Fired Water Bath Heaters are widely used for​​ safe and uniform heating​​ of gas and liquid streams.

Working Principle

The process fluid flows through a​​ coil immersed in a heated water bath, which is indirectly heated by a burner. This eliminates direct flame contact with the process fluid.

Key Advantages

• Uniform heat distribution

• Low thermal stress

• High operational safety

• Suitable for high-pressure gas service

Typical Applications

• PRMS gas preheating

• Fuel gas conditioning for power plants

• Gas dehydration and JT conditioning upstream heating

• Well stream heating

Design Features

• Fire tube and convection sections

• Natural gas / fuel gas burners

• Temperature control systems

• Safety shut-down and flame monitoring

• 

Direct Fired Heaters

Direct Fired Heaters transfer heat through​​ radiant and convective sections, where the process fluid is directly heated by combustion gases.

Applications

• Refineries and petrochemical plants

• Heavy hydrocarbon heating

• Crude oil and condensate processing

Key Characteristics

• High heat flux capability

• Rapid response to load changes

• Compact footprint for high-duty applications

Direct fired heaters are typically applied where​​ high temperatures and large heat duties​​ are required.

Process Gas Heaters

Process Gas Heaters are designed specifically for​​ natural gas and process gas streams​​ requiring precise temperature control.

Applications

• PRMS stations

• Gas conditioning and metering skids

• Fuel gas systems

• Compressor inlet heating

Heating Technologies

• Water bath heaters

• Shell & tube exchangers

• Electric gas heaters

These systems are engineered to maintain gas temperature​​ above hydrate and hydrocarbon dew point limits.

Electric Heaters

Electric Heaters provide clean, precise, and low-maintenance heating using electrical energy.

Advantages

• No combustion system

• Zero on-site emissions

• High temperature control accuracy

• Compact and modular

Typical Applications

• Remote installations

• Enclosed and containerized skids

• Hazardous areas where combustion is restricted

Electric heaters are often integrated into​​ small to medium flow gas conditioning systems.

Shell & Tube Heat Exchangers

Shell & tube heat exchangers are among the most versatile and widely used heat transfer equipment in the process industry.

Fixed Tube Sheet Heat Exchangers

Characteristics:

• Simple and robust design

• Cost-effective

• Suitable where shell-side cleaning is not frequent

Applications:

• Gas heating/cooling

• Oil heating

• Condensate service
