Design Basis

1.What is Design Basis?

-Shows the purposes of the process design, indicating the feed stocks, products, reactions, etc.
-Has all the basic requirements for the design of entire plant, individual processes and related facilities.
-Is to be established prior to basic design work.
-Is prepared by Contractor and approved by Client.
-Is used as specifications to be followed by a Process Licenser and/or Packaged Unit Vendor.

2.What are the classifications of Design Basis?

a.General Design Basis

-A document intended to specify the configuration of an onsite plant and its outline requirements.

b.Process Design Basis

-A document intended to specify the performance of a process unit and its outline requirements.

c.Facility Design Basis

-A document intended to specify the performance of the offsite and utility facilities and outline requirements.

3.What are the contents of Design Basis?

-Typical Contents of General Design Basis
-Typical Contents of Process Design Basis
-Typical Contents of Facility Design Basis

4.What is specific Design requirement?

The requirement depend specifically on the facility proper.

1.What is Natural Gas?
Natural gas
-a fossil fuel comprising mainly of methane.
-lighter than air, colorless, odorless and tasteless
-can be compressed, and therefore, transported in large quantities through relatively small pipelines when under high pressure

2.What is NGL?
Natural gas liquid (NGL)
-are the range of hydrocarbons in a natural gas stream that are heavier than methane (C1).  The components in an NGL mix include ethane (C2), propane (C3), butane (C5) and condensate (C5+).  The different components in an NGL mix can be fractionated or separated using a distillation process.  However, strictly speaking, the term NGL would generally exclude methane and ethane, since these hydrocarbons need refrigeration to be liquefied.
-NGLs (propane/butane) condense into liquids at relatively low pressure.

3.What is LNG?
-Natural gas, mainly methane and ethane, which has been liquefied at cryogenic temperatures. This process occurs at an extremely low temperature and a pressure near the atmospheric pressure. When a gas pipeline is not available to transport gas to a marketplace, such as in a jungle or certain remote regions offshore, the gas may be chilled and converted to liquefied natural gas (a liquid) to transport and sell it. The term is commonly abbreviated as LNG.
-It is neither corrosive nor toxic.

4.What is LPG?
-Gas mainly composed of propane and butane, which has been liquefied at low temperatures and moderate pressures. The gas is obtainable from refinery gases or after the cracking process of crude oil.Liquefied petroleum gas is also called bottle gas. At atmospheric pressure, it is easily converted into gas and can be used industrially or domestically. The term is commonly abbreviated as LPG.
-Liquefied petroleum gas, is normally  a product of crude oil distillation. It contains mostly propane, or C3H8. Propane has the nice property that, when you compress it, it condenses into a liquid. This means that it is much easier to store in a tank than natural gas, which does not easily compress. 

5.What is mercaptans?
-A trace amount of smelly organic sulfur compounds (tertiary-butyl mercaptan, (CH3)3CSH and dimethyl sulfide, CH3–S–CH3) is added to give commercial natural gas a detectable odor. This is done to make gas leaks readily detectible. An undetected gas leak could result in an explosion or asphyxiation.
-MERCAPTANS (Thio-alcohols), organic chemical compounds of the type R.SH (R = an alkyl group). The name is derived from mercurium captans, in allusion to the fact that these compounds react readily with mercuric oxide to form crystalline mercury derivatives. Mercaptans are a group of sulfur-containing organic chemical substances

6.What is Petroleum?
-A broad term which includes both crude oil and natural gas.
