The world would look different without ethylene. Many industries need this hydrocarbon to produce their goods – automotive, construction, the healthcare sector, as well as the packaging industries. With more than 150 million tonnes a year the global production is higher than any other organic compound.
We dedicate our entire know-how to your specific demands. In every step, we aim at adapting our heat exchanger system for steam cracking processes perfectly to your ethylene plants.
Our SCHMIDT’SCHE® Transfer Line Exchangers are at the heart of the cracking process. By positively influencing the ethylene yields and maximizing the energy recovery it contributes significantly to the profitability of each ethylene plant.
The demand for steam reforming based products for chemical and refinery processes grows constantly. We meet your individual demands.
Different steam reforming processes are the result of a knowledge-based interaction between the process heat transfer and reaction kinetics.
Plant capacity, product specifications, catalyst technology, feedstock characteristics and desired steam production vary in each individual case.
By optimum integration of process gas cooling and waste heat recovery the SCHMIDT’SCHE® Process Gas Boilers and Heat Recovery Systems ensure the reliability of your plant coming along with an economic and efficient operation.
Gasification & POX
Gasification technology represents an alternative feedstock based chemical and fuel production system. Gasification breaks down virtually any carbon based feedstock including hazardous materials into its basic constituents. Natural gas, oil, coal and refinery residues are still dominant raw material for their production. However, the industrial gasification of municipal solid waste and biomass is also steadily growing in importance globally.
The flexibility to co-produce multiple chemical commodities and different fuels makes the technology economically attractive for a broad range of industrial applications. Excellent energy efficiency, lower emissions and the potential of waste recycling are clear advantages of gasification technology.
High temperatures and pressures, corrosive and erosive as well as dust or by-products laden syngas compositions have to be handled by the process equipment.
The combination of well-established and innovative reactor and syngas cooler technologies is leading to the most up to date and economic process solutions. Our unique SCHMIDT’SCHE® and SCHACK® solutions are applied for small size up to world scale gasification plants.
The global population is growing constantly. Nourishing all people will be one of the most crucial challenges we have to face. Nitric acid prepares the soil for bountiful crop.
Industrially produced fertilizers are and will be indispensable for healthy plant growth and consequently food production in general.
Nitric acid (HNO3) is an important raw material for producing fertilizers and other chemical substances that we need for our everyday life.
Caprolactam is a further important material used for the production of fiber e.g. for the textile industry and can also be produced with nitric acid process equipment,
SCHACK® Process Gas Cooler have their important share in extracting this valuable compound.
Carbon black is used as a high performance reinforcing component in technical rubber products and as a color pigment. It determines the quality and defines the characteristics of the final product. A great amount of the technical Carbon Black is produced by the application of SCHACK® Air Preheaters.
Technical carbon black is produced by subjecting Carbon Black feedstocks, hydrocarbon liquids or gases, to extremely high temperatures in a carefully controlled combustion process.
Preheating the process air to high temperatures by recuperating the energy from the particle laden process gas is one of the main challenges to optimize plant economics and maximize production output.
The comprehensive solutions of SCHMIDTSCHE SCHACK for Carbon Black Industry cover the most important aspects of Carbon Black production process, starting with quenching of the reaction, preheating of required air for the combustion process up to drying of the final product and integrating a heat utilization facility.
To us, sustainability is the value of paramount importance. And we are keen to contribute to finding solutions for a greener tomorrow.
Worldwide, there is a clear and growing need for alternative municipal sludge disposal. Methods such as landfill or agricultural usage can be seen as critical from an environmental perspective.
Sludge mono-incineration offers a way of municipal sludge incineration that ensures safe and environmentally friendly disposal, recovery of energy and recovery of scarce resources such as phosphorous at the same time.
During the incineration process and especially the flue gas cooling process, a variety of challenges for the process equipment are coming up. High temperatures as well as dust laden erosive and corrosive gas compositions are just some of the challenges to be handled by the process equipment.
Our solution offering around our tried and tested SCHACK® Air Preheaters is made to handle these challenges.
The white pigment titanium dioxide is found in many everyday things: the substance lightens toothpaste, sun cream, chewing gum, and many other of our daily products.
As an additive, it is noted on some food packaging. Cosmetic products also contain the chemical. However, the substance is most frequently found in paints, varnishes, and other coatings.
No wonder, then, that the worldwide demand for titanium dioxide is so great for this broad application: around 7 million tons are produced worldwide every year.
Customized SCHACK® Fired Heaters contribute very much to satisfy the markets needs in a very efficient manner.
Glass smelting process
The art of glass making traces its roots to c. 3000 BC when it was used as a glaze on ceramic vessels. Over the years, the glass smelting process was further developed. Today, huge furnaces with high temperature levels are used to melt the feedstock for the glass production. Depending on its composition, it can have a melting point of about 1400-1600 °C.
Glass is an integral part of today’s life and is used universally in industry, research, construction and private households.
Our SCHACK® Recuperators are suited for highest waste gas temperatures in systems where exhaust gases have high dust concentrations, such as glass melters and kilns.
Sulphuric acid is one of the most important industrially produced chemicals. The main part is used for the production of fertilizers and pigments. Sulphuric acid is also of great importance for countless organic-technical syntheses as a reaction partner, catalyst or reaction auxiliary. Modern detergents, pharmaceuticals, dyestuffs for textiles and some man-made fibres could not be produced without this substance or could only be produced with greater effort.
Direct reduction iron
In direct reduction processes iron oxide is reduced to iron. The resulting product named Direct Reduced Iron (DRI) has a high content of metallic iron and of low content of carbon.
Being used as raw material for high quality steel making in the Electric Arc Furnace, DRI is gaining increasing prominence as feedstock for this process. The benefits of DRI are significant.
As natural gas is widely available at low cost, steel can be produced at favorable prices.
Additionally, using DRI in steelmaking greatly reduces carbon emissions, increases capacity and improves the quality of the steel product. All these factors lead to a high economic efficiency of the DRI plant. The reduction of iron oxide takes place in the shaft furnace at temperatures below the melting point of the solid material. In this process SCHACK® Heat Recovery Systems play an important role.
Acetylene is multifaceted and fascinating. Within the steam cracking process, acetylene is incidentally produced as a byproduct. However, it is also exclusively produced in large-scale acetylene plants.
It is a valuable starting material and of great industrial importance. Beyond its obvious value as welding gas, acetylene has many other less-well-known applications. It is used to produce certain plastics and chemicals and also plays a role in organic synthesis (laboratory work) and chemical synthesis. Acetylene is also used in plant cultivation, improving the forming of new flowers. In addition to that, it is also used as a carbon source in molecular manufacturing, in calibration gases for the gas, oil and chemical industries and in lung testing gases.
Our SCHACK® Fired Heaters are made to deal with the process challenges during the acetylene production and play an important role within the acetylene plant.
