Plant Engineering119 Standard Conditions / Normal Conditions The standard and normal conditions for volumetric measurement of gas and liquids are defined at pressure and temperature of: - Standard Conditions : 1.01325 Bara and 15.6 deg.C - Normal Conditions : 1.01325 Bara and 0 deg.C 2014. 9. 30. Priming System Sizing http://lynnengineeredsystems.com Priming System Sizing Proper sizing of a vacuum priming system is based on the required volume of air to be removed from the suction piping within the acceptable period of time. Sizing also depends on whether operation of the system is On Demand, where priming is done before each time a pump needs to start or Automatic systems that maintain a constant prime for i.. 2014. 8. 4. Priming System Selection http://lynnengineeredsystems.com Application Analysis Determining the proper system type and sizing for the application is the first step in selecting a vacuum priming system. Selecting the proper type of system depends upon the application requirements of the pump or pumps that require priming. There are two system types to consider, On-Demand priming or Automatic priming. Each system type is a.. 2014. 8. 4. Nominal capacity / Design capacity Q : What is the difference between nominal and design capacity? A : Nominal capacity is the total liquid hold-up capacity of the Tank and Design capacity is the liquid hold up capacity up to High-High Liquid level. 2014. 7. 28. 플랜트 구매 (Plant Procurement) 플랜트 구매 (Plant Procurement) [출처] 링마벨 엔지니어링 블로그 "Engineering 뽀개기" 플랜트 구매는 Process engineer 입장에서 보면, 가장 거리가 먼 분야에 속합니다. 구매과정에 참여하는 것은 기껏해야 TBE (Technical Bid Evaluation) 정도이고, 그나마도 주체적인 것이 아닌 support 가 전부입니다. 그래도 알아서 나쁠건 없으니 정리해 보도록 하겠습니다. Design 관점에서 살펴보면, 어느 단계까지 비교적 자유롭게 design change 가 가능한지 감을 익히는 것도 좋을 듯 합니다. 1. The Role of Procurement 1) Project 수행에 필요한 기기, 자재 등을 구입하는 업무 2) 기기, 자재에 대한 사전 검증 (.. 2014. 7. 28. Pump Seal Plan Pump Seal Plan [출처] 링마벨 엔지니어링 블로그 "Engineering 뽀개기" Seal Plan 의 목적은 pump 내의 rotating part (eg. shaft) 와 stationary part (eg. baering) 사이의 마모를 줄이는데 있습니다. Process fluid (pumping fluid) 의 property (flammability, toxic, hazardous, harmful, Hydrocarbon, etc...) 에 따라 single seal 과 double seal 로 구분이 됩니다. 다시 double seal 은 Seal Reservior 의 pressure 가 Seal Chamber pressure 보다 높거나 적느냐에 따라 plan 이 구분됩니다. 보통 .. 2014. 7. 23. 이전 1 ··· 8 9 10 11 12 13 14 ··· 20 다음 728x90 반응형
