Dry gas seals have really gained popularity over the last 20 years. Being the seal system of choice for the process gas centrifugal compressors thus increasingly replacing the traditionally complex oil fill seals. It is estimated that almost 80% of the process gas centrifugal compressors manufactured today are equipped with dry gas seals, implying acceptance […]
Fins are used to enhance the heat transfer on a surface by increasing the surface area for heat transfer to take place. For convective heat transfer from a surface, the governing equation is: Q=h*A*(Ts-Tinf) Where Q is the rate of heat transfer from a surface to a fluid, h is the convective heat transfer coefficient, […]
As the world population increases and the demand for plastics skyrockets, the process of propane dehydrogenation has gained widespread momentum. Propane Dehydrogenation or PDH is a process that converts a propane feedstock to propylene which is used commonly in various petrochemical applications. As the global demand for propylene increases in the automobile sector, manufacturing of […]
Plastics are an all but inevitable part of our lives. From alarm clocks and coffee cups to the cars we drove in with, most of us have had nonstop interactions with plastic between waking up and just getting into the office. The plastics industry is a major component of everyday life. Plastics processing methods are […]
Mines are getting deeper and are working with more complex ores and materials. Add in rising energy costs, a greater need for efficiency, and increased public pressure on environmental impact and the industry is in severe need of adopting technological advances. Electric heaters, and drywell immersion heaters in particular, are helping the mining industry overcome […]
