The entrance of oil through the oil seals into refrigeration systems will reduce the capacity of the system and impact on process unit revenue. To ensure that seal oil does not enter the process loop and foul the chillers, it is essential that lube/seal oil reservoir level on all refrigeratio

A minimum of one meter distance has to be specified between all oil system components to allow operator access, and to optimize system reliability. Access to all major components is essential to allow operator intervention to switch over to spared system com
After determining how long you want the equipment to last and identifying the process and fluid properties, it is time to select the pump. Factors for minimum life cycle costs include installation, maintenance, energy, safety and environmental and possibly other considerations.
Finding an Advanced System to Design Supercritical CO2 Power Plants
April 7 2014 -
The supercritical CO2 power cycle is one of the most promising power technologies. It is not by chance though, because carbon dioxide (CO2) has a unique combination of attributes, such as a low critical temperature, an environmentally natural origin, a high standard of safety and a low cost. Carbon dioxide is also thoroughly studied, therefore there is sufficient information surrounding it. But on the other hand, the supercritical CO2 cycle has a high energy conversion factor, such as high thermal efficiency.

Five basic criteria for selection and application of pumps
June 15 2013 -
There are a lot of questions to be answered when choosing a pump. I have found that there are five basic criteria that need to be determined before any selection is done, or application of the same. Some of these will sound obvious, and some of the companies and individuals may say they support all of these criteria. But they take short cuts in making the choice in order to save money.
Leonid Moroz is the Founder & CEO of SoftInWay and has over 30 years experience in turbomachinery designing flow path for gas turbines up to 115MW and steam turbines up to 1000MW. At SoftInWay, he leads the development of AxSTREAM, the “gold standard” software suite for conceptual design and optimization of turbomachinery, and advises the consulting team on turbomachinery design projects.
One of the most important factors that should be considered in the design (and operation) of any turbomachinery is the thermal structure (or the thermal arrangement). Appropriate materials, cooling systems and insulations (or thermal shields) should be selected for turbomachinery based on a proper thermal analysis.
