Fuel Gas Conditioning

Fuel gas conditioning is a critical optimization process for the removal of damaging impurities from gas streams.

Unchecked contaminants such as particulate matter, water, heavy hydrocarbons, condensed gas, hydrogen sulfide, or siloxanes can reduce efficiency, lead to unplanned outages, or cause systems to fall out of compliance.

Many fuel gas conditioning processes require heat energy to function properly, and Sigma Thermal manufactures a number of products specifically for these applications.  Some common examples include dew point (Joule-Thompson) heating, performance heating, and regeneration gas heating.  There are typically a number of heating systems that can be used for these applications, and each one of those system types has its own unique advantages and disadvantages.  Sigma Thermal’s application engineers can help you decide which type of heating system is right for your fuel gas conditioning process and your specific facility.

Automation Solutions

Sigma Thermal Automation offers comprehensive and cost effective solutions to complex industrial challenges.

Our experienced engineers, designers, programmers and fabricators work together to execute all project specifications and requirements.

Electric Process Heaters

Electric process heaters serve to raise and maintain the temperature of process fluids in industrial equipment and operations. Through an immersed heating element in direct contact with the process fluid, they effectively convert electrical energy to thermal energy to heat the liquid or gas in a system.

As a trusted source for reliable, efficient, and versatile industrial process heating systems, Sigma Thermal designs and manufactures our direct and indirect heating solutions to accommodate myriad applications. At a typical 2 to 60 watts per square inch, our various heater types come standard or as custom-engineered systems built to your exact specifications and site requirements.

Industrial Waste Heat Recovery Systems

Biomass Energy Systems

Providing modern Biomass-fired energy systems and related equipment for industrial clients worldwide.

Sigma Thermal provides complete packaged biomass systems for industry.  The design, engineering, and manufacturing of our systems are backed by decades of energy experience. Packaged biomass energy systems incorporate a fuel feed system, ash handling system, and electric automation controls. Installation supervision, training, parts, and equipment service management are provided to help maintain and support efficient operation for the life of the system.

Reciprocating Grate Furnace Design

The Sigma Thermal reciprocating grate furnace is the most effective design for complete combustion of waste materials with low heating value, high moisture content, and high ash content. Our design allows for finite combustion control, minimizing emissions and utilizing a large range of different waste fuels, with varying characteristics (i.e. chemical composition, fuel size, and moisture content).

Process Bath Heaters

A process bath heater allows a user to indirectly heat process liquids and gases by submerging a process coil into a heated bath solution.

A process bath heater is a simple and safe method for indirectly heating various process mediums. A bath solution is heated by a fire tube style burner submerged at the bottom of the heater vessel. The bath solution then heats a submerged process coil, in which the flowing process medium is heated. Water-glycol mixtures are very common solutions for most low-temperature heating applications, and can typically be used up to 250F. Salt melts can be used to meet the higher operating temperature requirements in some specialized applications.

Direct Fired Heaters

Sigma Thermal offers convection style, API 560, and non-API radiant convective heaters from 1MM to 80MM Btu/hr.

A direct fired heater is a style of heater in which a burner provides hot gasses that transfer their heat energy to a process liquid or gas flowing directly through coils installed inside the heater vessel. Direct fired heaters can utilize radiant and/or convection heat transfer sections, and can be configured in many different ways depending on the customers’ specific requirements. Due to the flexibility in design, virtually any style of furnace burner can be used in single or multi-burner configurations.
