The site navigation utilizes arrow, enter, escape, and space bar key commands. Left and right arrows move across top level links and expand / close menus in sub levels. Up and Down arrows will open main level menus and toggle through sub tier links. Enter and space open menus and escape closes them as well. Tab will move on to the next part of the site rather than go through menu items.
Our waste heat recovery unit (WHRU) captures heat from exhaust gasses of gas-powered turbines or other equipment that generate large volumes of heat. This is heat that would otherwise be wasted into the atmosphere. Instead, a large portion of the heat from those exhaust gasses is transferred to thermal fluid flowing through coils inside the WHRU. The heated thermal fluid provides heat for other applications. Other designs are available and are fully customizable to the needs of the application.
It’s estimated that 20%-50% of energy is lost as waste heat in manufacturing processes where heat is used to make products. Waste heat is energy generated that goes unused and is lost to the environment. Waste heat can come from process systems, flue gasses, generators, turbines, cooling water, equipment surfaces, oxidizers, etc. But waste heat doesn’t have to go completely to waste. There are opportunities and technologies that allow manufacturers to put it to practical use.
Crude Oil & Natural Gas Processing
Oil refining and gas processing are procedures that turn these complex chemical mixtures into a range of usable fuels. Refining and processing crude oil and natural gas require highly reliable and efficient heating systems and services. Astec produces a number of reliable and efficient components for use in oil refining and gas processing including heaters, tanks, heat recovery systems, and expansion tanks.
Throughout the asphalt/roofing industry efficient heating systems and services are needed as well as reliable storage systems. Astec has an extensive background supplying equipment designed for heating and storing liquid asphalt as well as experience with all types of thermal systems.
Power generation is essential to modern life and industry. The power generation industry depends on heating equipment and systems to meet its demands. Astec serves the power and electricity generation industry with a number of products such as thermal fluid heaters, process heaters, heat economizers, and expansion tanks and pump skids.
The petrochemical industry is fundamental to our contemporary world. It supplies many of the raw materials that we rely on: plastics, medicines, lubricants, synthetic rubbers, and synthetic fibers. The petrochemical industry relies heavily on various thermal processes and heat-controlled methods to produce its vital materials. Astec components used in the petrochemical industry include heaters, controls, steam generators, and heat recovery systems.
Chemical plants convert oil, natural gas, air, water, metals, and minerals into chemical products which are used to manufacture numerous consumer products and play an important part in agriculture, manufacturing, construction, and service industries. The transfer of heat is an essential component of all chemical processes. An efficient heat transfer system is a key to manufacturing many chemicals.
A thermal mixing process is required to turn aggregates and liquid AC into an asphalt pavement mix for road construction. This makes an asphalt mixing plant necessary for road construction. The complete line of Astec asphalt mixing plants, and its range of capacities and features, gives you the choices and flexibility to create your optimum solution.
