10. CODES & STANDARDS FOR PROCESS PIPING… A code is a set of regulations that tells you when to do something. A code will have requirements specifying the administration and enforcement of the document. A standard is a series of requirements that tell you how to do something. A standard tends not to have any enforcement requirements. A standard becomes an enforceable document when it is adopted by reference in a code. 10

11. COMMON CODES, STANDARDS & PRACTICES ANSI (American National Standards Institute) API (American Petroleum Institute) ASME (American Society of Mechanical Engineers) ASTM – American Society of Testing Materials AWS (American Welding Society)– AWWA (American Water Works Association) CFR (Code of Federal Regulations) Division of Weights & Measures DOT (Department of Transportation) FAR (Federal Accounting Regulations) IRI (Insurance Regulators Institute) Local Permits (Country, State, City, etc.) MSS (Manufacturing Standards Society) NACE (National Association of Corrosion Engineers) NFPA (National Fire Protection Association) OIA (Oil Insurers Association) PFI (Pipe Fabrication Institute) TEMA = Thermal Exchangers Manufacturers Association USCG (United States Coast Guard) Regulations 11

19. HOT GAS BYPASS Hot gas bypass is a method of maintaining compressor suction pressure (creating a false load) during light loads. This has the effect of modulating compressor capacity below the minimum unloading point without cycling the compressor. It is accomplished by returning hot (discharge) gas from the leaving side of the compressor back to a point on the low-pressure side of the refrigeration circuit. 19

24. Cooling tower Points to remember to increase the efficiency of a cooling tower : Depending on the type of cooling tower, the specific water treatment requirements may vary, but in general, the three main areas of the cooling tower process that typically require treatment are: feed water to the cooling tower, circulatory water in the tower, and cooling tower bleed to drain . Material of construction of Cooling Tower Losses in Cooling Tower Improve the efficiency of your chemical usage Install a variable frequency drive (VFD) 24

25. boiler PERFORMANCE EVALUATION OF BOILERS (BOILER EFFICIENCY) DIRECT METHOD : This is also known as ‘input-output method’ due to the fact that it needs only the useful output (steam) and the heat input (i.e. fuel) for evaluating the efficiency. This efficiency can be evaluated using the formula: 𝐵𝑜𝑖𝑙𝑒𝑟 𝐸𝑓𝑓𝑖𝑐𝑖𝑒𝑛𝑐𝑦=(𝐻𝑒𝑎𝑡 𝑂𝑢𝑡𝑝𝑢𝑡/𝐻𝑒𝑎𝑡 𝐼𝑛𝑝𝑢𝑡)∗100 INDIRECT METHOD : Indirect method is also called as heat loss method. The efficiency can be arrived at, by subtracting the heat loss fractions from 100. The standards do not include blow down loss in the efficiency determination process. 25 DESIGN…
