Effective instrument commissioning enables seamless project startups. © 2020 HRS Heat Exchangers. If the information provided to the designers of the heat exchanger is wrong or incomplete, then the installed unit will not perform optimally for the product and service fluid in question. Failure to obtain the correct information will result in a heat exchanger which, at best, is inefficient and, at worst, inoperable. All of these effects can be prevented by using the right heat exchanger. AspenTech's Ron Beck explains the concept of Self-Optimizing Plant and how it will support industrial organizations as they adapt to new conditions, helping them achieve greater resilience and better business outcomes. Bear in mind that cheaper isn’t necessarily best. more information Accept. You should always request full details about any new products from your suppliers and, if necessary, ask your heat exchanger supplier to test them before use. Stop these critical components from impacting operations when broken or not operating properly. For example, although carbon steel is cheaper than stainless steel and easier to work with – making it a popular choice for those on a budget – it is also more vulnerable to corrosion and chemical reaction. The pressure drop on the tube side of a shell-tubes heat exchanger is made of several components : the pressure drop in the inlet nozzle, the pressure drop in the outlet nozzle, the pressure drop in the return cover and the pressure drop through the tubes. If you are tight on space, ensure you specify a heat exchanger suitable for a small footprint. A well-designed heat exchanger should therefore include fail-safes to prevent damage from occurring in the event of a system failure elsewhere in the production line — for example, heating coils or a diversion system to prevent chilled products from freezing in the event of pump failure. This can result not only in product damage, but can also have additional effects on the equipment. It is also important to make sure that heat exchanger equipment is included within any monitoring and alarm systems. For example, corrugated tube designs are more efficient and require less space than a smooth-tube unit with the same capacity. Inappropriate product handling can affect quality parameters, such as taste, appearance and viscosity. Simplifying temperature measurement to deliver improved safety and increased productivity. Thicker tube walls are required compared to stainless steel, which increases the weight of comparable heat exchanger units and may add to associated costs, such as concrete bases and mounting brackets. Furthermore, carbon steel is brittle and while it may have a higher thermal conductivity than other materials, this can rapidly be degraded by the build-up of corrosion or fouling layers, reducing its service life. The problems caused by specifying the wrong type of material for your heat exchanger range from the need for additional cleaning, through to a catastrophic failure of the unit. It is also important to make sure that heat exchanger equipment is included within any monitoring and alarm systems. One reason for an increase in the pressure drop might be a change in raw material specification (for example, switching ingredient suppliers). Heat transfer is not the consequence (or effect) of pressure drop. To realize its potential, IIoT solutions must address the role of the connected industrial worker in this brave new world. Total pressure drop on the tube side. Excessive fouling reduces heat exchanger efficiency and can lead to other problems. Pressure problems usually occur when the pressure drop in the heat exchanger is higher than the design parameters; one reason might be a change in raw material specification.
