Gasification and Partial Oxidation are versatile high-temperature processes that transform solid, liquid, or gaseous carbon-based feedstocks into valuable synthesis gas (syngas). Our SCHMIDT’SCHE® and SCHACK® technologies provide the core components for this process – from high-performance reactors and gasifiers to advanced syngas coolers – ensuring reliable operation, high energy efficiency, and long-term durability.
Our equipment is designed to withstand the extreme conditions of gasification: high pressures, abrasive and corrosive syngas, and temperatures up to 1,600 °C. Whether for fossil-based or renewable feedstocks, our proven and modular solutions support a wide range of industrial applications – from fuel and chemical production to power generation.
Every unit is tailored to process-specific requirements. While each design is unique, the core of our syngas and gasification product portfolio stands for robust performance, custom-fit engineering, and maximized plant efficiency.
At SCHMIDTSCHE SCHACK, we deliver custom-engineered solutions for high-temperature syngas processes with a strong focus on efficiency, durability, and process integration. Whether in gasification, partial oxidation, or syngas cooling, our technologies are designed to handle extreme thermal and mechanical stresses while maximizing heat recovery and operational stability.
The SCHMIDT’SCHE® Syngas Cooler is based on our proven Double Tube & Oval Header Technology, offering optimized protection against erosion, deposits, and uneven flow conditions – ideal for coal and petcoke gasification.
The SCHACK® Syngas Cooler GFC (Gasification) provides robust heat transfer in systems with high dust and slag loads. Its water tube design ensures stable performance, low pressure drop, and easy maintenance for challenging syngas environments.
For partial oxidation reactors, the SCHACK® POX Syngas Cooler features our patented gas inlet nozzle and a self-cleaning tube design, protecting against corrosion, erosion, and metal dusting while allowing efficient part-load and online cleaning operation.
Our Reactors and Gasifiers are designed for maximum flexibility in feedstock and process configuration. Whether for RWGS, methane pyrolysis, or large-scale POX plants, we offer membrane wall or refractory-lined solutions with integrated radiant, convective, or quench cooling – enabling higher reaction rates, increased product yields, and greater sustainability.
The SCHMIDT’SCHE® Syngas Cooler is engineered to meet the demanding needs of gasification processes. Utilizing our proven Double Tube & Oval Header Technology, this cooler effectively handles harsh operating conditions and high abrasive dust loads common in coal and petcoke gasification applications.
Our Syngas Coolers combine the advantages of both fire tube and water tube designs, offering superior protection against tube inlet erosion and the formation of gas-side deposits. The innovative design eliminates the need for ferrules, ensuring long-term reliability and durability.
Each tube is equipped with its own cooling elements, allowing the system to self-adjust based on the individual heat load. This results in optimized heat recovery and improved process efficiency, even in the presence of uneven gas flow distribution.
With thin-walled oval headers, the cooler minimizes mechanical and thermal stresses, protecting the magnetite layer on the tubes and ensuring extended operational life. High cooling water flow velocities further enhance cooling efficiency and ensure the removal of particles that could damage the equipment.
Your Benefits
The SCHACK® Syngas Cooler is designed for high gas inlet temperatures, providing efficient heat recovery while preventing liquid or sticky slag particles from contacting the heat transfer surface. By generating high-pressure steam through heat transfer from the raw gas, it plays a critical role in gasification processes.
Available in membrane wall or double shell designs, the cooler is built to withstand extreme temperatures, improving process efficiency by up to 5% compared to direct water quenching systems. The integrated water bath and slag crusher safely reduce slag fragments to manageable sizes for downstream processing.
Your Benefits
The SCHACK® POX Syngas Cooler is engineered for partial oxidation (POX) reactors, handling extreme temperatures up to 1,5 °C and feedstocks rich in heavy metals. With our patented gas inlet nozzle design and superimposed cooling, it offers reliable protection against corrosion, erosion, and metal dusting.
Its self-cleaning tube geometry maintains heat transfer efficiency, while thin-walled surfaces ensure precise temperature control. Designed for easy access, the replaceable coils and interchangeable inlet tubes reduce maintenance time and increase system uptime.
Your Benefits
Our SCHMIDT’SCHE® and SCHACK® Reactors and Gasifiers are engineered for high-temperature applications such as partial oxidation (POX), reverse water gas shift (RWGS), and methane pyrolysis. Designed to process liquid, gaseous, or solid feedstocks at temperatures up to 1,60 °C and pressures up to 100 bar, they deliver efficient conversion and maximum process flexibility.
Depending on your process, we offer refractory-lined or membrane wall designs, supported by custom cooling concepts including radiant, convective, or direct quench systems. Our technologies are used in projects ranging from compact systems to the world’s largest-scale gasification plants.
By operating at elevated temperatures, our reactors enable faster reaction rates, higher yields, and improved process efficiency, while also allowing for the use of waste heat or renewable energy for greater sustainability.
