Occasionally, direct fired heaters that have operated satisfactorily for long periods of time subsequent to startup develop operating problems that do not allow for operation at design conditions, as specified in the manufacturers API data sheets for the heater. Performance…
Shell-and-tube heat exchangers are one of the most important and commonly used process equipment items in the chemical process industries (CPI). If you are working on a project during either the basic or the detailed engineering phase, there is a…
Larson Electronics The recently launched WALBL-2 x 1000WMH Boiler Light is a telescoping light tower with a folding boom that is designed to allow versatile deployment and high-output illumination. The light features a right-angle extension arm, wheeled base, and a…
Many chemical manufacturing processes require large amounts of energy, and chemical companies are faced with the constant challenge of determining how to use that energy as sustainably as possible. More and more chemical companies are prioritizing a range of energy…
The continuing development of natural gas extraction from shale deposits, known simply as shale gas, is fueling the growth of simple- and combined-cycle power plants. Much coal-fired power is being replaced by these technologies. In addition, though, simple- and combined-cycle…
The carbon-fiber pilot line consists of an oxidation furnace, carbonization furnace and a graphitization furnace, The four-zone oxidation furnace operates at 325°C for stabilizing precursor fibers, and has a connecting two-step system for carbonization and graphitization at the required temperatures…
The CS10 Clean Steam Separator with enhanced surface finish has been engineered to overcome problems associated with wet steam and ensures the correct quality of steam is supplied to the point of use, thereby preventing damage to control valves and…
The HVF-Freezer (high-velocity freezer) is said to be an improved freezer concept based on existing impingement-freezer technology. The new HVF uses high-velocity air jets to quickly reduce the outer layer temperature of food by breaking the insulating boundary layer, allowing…
Changing out used heat-transfer fluid is critical to the efficiency of a heat-transfer fluid system. A well-operated heat-transfer-fluid system can enable efficient production, fewer shut-downs, less maintenance time and lower costs. In order to maintain a sound heat-transfer system, it…
Supplying steam that meets process needs while protecting steam-system components, such as boilers and steam turbines (Figure 1), against scale, fouling and corrosion, requires purified feedwater (condensate plus makeup water). Depending on the steam pressure required, the specific approach of…
