Payables

An accounting entry that represents an entity's obligation to pay off a short-term debt to its creditors. The accounts payable entry is found on a balance sheet under the heading current liabilities.

Accounts payable are often referred to as "payables".

Another common usage of AP refers to a business department or division that is responsible for making payments owed by the company to suppliers and other creditors

Oracle Product Lifecycle Management

What is PLM, or Product Life Cycle Management? Good question and one we should define before we help you: decide if you need it, explain how it can help you and figure out what parts of it you need - or don't need. Product Lifecycle Management can be interpreted in numerous ways. Leading authorities provide their own interpretation of PLM, a variety of which are listed below:

"PLM is a strategic business approach that applies a consistent set of business solutions in support of the collaborative creation, management, dissemination, and use of product definition information across the extended enterprise, and spanning from product concept to end of life-integrating people, processes, business systems, and information. PLM forms the product information backbone for a company and its extended enterprise." Source:  CIMdata

"Product life cycle management or PLM is an all-encompassing approach for innovation, new product development and introduction (NPDI) and product information management from ideation to end of life. PLM Systems as an enabling technology for PLM integrate people, data, processes, and business systems and provide a product information backbone for companies and their extended enterprise." Source:  PLM Technology Guide

"The core of PLM (product life cycle management) is in the creations and central management of all product data and the technology used to access this information and knowledge. PLM as a discipline emerged from tools such as CAD, CAM and PDM, but can be viewed as the integration of these tools with methods, people and the processes through all stages of a product's life." Source:  Wikipedia article on Product Lifecycle Management

"Product life cycle management is the process of managing product-related design, production and maintenance information. PLM may also serve as the central repository for secondary information, such as vendor application notes, catalogs, customer feedback, marketing plans, archived project schedules, and other information acquired over the product's life." Source:  Product Lifecycle Management

"It is important to note that PLM is not a definition of a piece, or pieces, of technology. It is a definition of a business approach to solving the problem of managing the complete set of product definition information-creating that information, managing it through its life, and disseminating and using it throughout the lifecycle of the product. PLM is not just a technology, but is an approach in which processes are as important, or more important than data." Source:  CIMdata

"PLM or Product Life cycle Management is a process or system used to manage the data and design process associated with the life of a product from its conception and envisioning through its manufacture, to its retirement and disposal. PLM manages data, people, business processes, manufacturing processes, and anything else pertaining to a product. A PLM system acts as a central information hub for everyone associated with a given product, so a well-managed PLM system can streamline product development and facilitate easier communication among those working on/with a product.

Oracle Service Management solution

Service management is integrated into supply chain management as the intersection between the actual sales and the customer. The aim of high performance service management is to optimize the service-intensive supply chains, which are usually more complex than the typical finished-goods supply chain. Most service-intensive supply chains require larger inventories and tighter integration with field service and third parties. They also must accommodate inconsistent and uncertain demand by establishing more advanced information and product flows. Moreover, all processes must be coordinated across numerous service locations with large numbers of parts and multiple levels in the supply chain.
Among typical manufacturers, post-sale services (maintenance, repair and parts) comprise less than 20 percent of revenue. But among the most innovative companies in Service, those same activities often generate more than 50 percent of the profits.  (source - Wikipedia )

Crude Oil Refining

A refinery is a factory. A refinery takes a raw material (crude oil) and transforms it into petrol and hundreds of other useful products. A typical large refinery costs billions of pounds to build and millions more to run and upgrade. It runs around the clock 365 days a year, employs  hundreds of people and occupies as much land as several hundred football pitches.
A REFINERY breaks crude oil down into its various components, which then are selectively changed into new products. This process takes place inside a maze of pipes and vessels. The refinery is operated from a highly automated control room.
All refineries perform three basic steps:

• Separation (fractional distillation)
• Conversion (cracking and rearranging the molecules)
• Treatment

Oil Refinery Processing and Outputs

• It is important to realise that the column is hot at the bottom and cool at the top.
• The crude oil separates into fractions according to weight and boiling point.
• The lightest fractions, including petrol and liquid petroleum gas (LPG), vapourise and rise to the top of the tower.
• Kerosine (aviation fuel) and diesel oil, stay in the middle of the tower
• Heavier liquids separate lower down.
• The heaviest fractions with the highest boiling points settle at the very bottom.

The following table shows how the behaviour of the hydrocarbon molecules alter:

AT THE TOP OF THE COLUMN		AT THE BOTTOM OF THE COLUMN
Short carbon chains		Long carbon chains
Light molecules		Heavy molecules
Low boiling points		High boiling points
Gases & very runny liquids		Thick, viscous liquids
Very volatile		Low volatility
Highly flammable		Not very flammable
Light colour		Dark colour
Petrol comes off near the top of the column. Does the list above describe petrol?		Fuel oil comes off near the bottom of the column. Does the list above describe fuel oil?

The fractions are now ready for piping to the next areas within the refinery. Some fractions require very little additional processing. However, most molecules require much more processing to become high-value products.

Conversion: cracking and rearranging molecules Some fractions from the distillation towers need to be transformed into new components . This is where a refinery makes money, because the low-value fractions that aren't in great demand can be converted to petrol and other useful chemicals.

The most widely used conversion method is called cracking because it uses heat and pressure to "crack" heavy hydrocarbon molecules into lighter ones. A cracking unit consists of one or more tall, thick-walled, reactors and a network of furnaces, heat exchangers and other vessels. Catalytic cracking, or "cat cracking," is the basic petrol-making process. Using intense heat (about 600°C), low pressure and a powdered catalyst (a substance that speeds up a  chemical reaction), the cat cracker can convert most of the heavy fractions into smaller more useful molecules. Some refineries also have cokers, which use heat and moderate pressure to turn the really heavy fractions into lighter products and a hard, coal like substance that is used as an industrial fuel. Cracking and coking are not the only forms of conversion. Other refinery processes, instead of splitting molecules, rearrange them to add value. Alkylation makes petrol components by combining some of the gaseous byproducts of cracking. The process, which essentially is cracking in reverse, takes place in a series of large, horizontal vessels.

Reforming uses heat, moderate pressure and catalysts to turn naphtha into high-octane petrol.

Treatment: the finishing touch

Today, a major portion of refining involves blending, purifying, fine-tuning and improving products to meet specific requirements. To make  petrol, refinery workers carefully blend together a variety of hydrocarbons. Technicians also add performance additives and dyes that distinguish the various grades of fuel. By the time the petrol is pumped into a car it contains more than 200 hydrocarbons and additives.
Example: Petrol companies produce different blends of fuels to suit the weather. In winter, they put in more volatile hydrocarbons (with short carbon chains) and in summer they add less volatile hydrocarbons to compensate for the higher temperatures.

Modern separation involves piping crude oil through hot furnaces. The resulting liquids and vapours are passed into distillation towers:-

		FRACTION	B Pt  oC	Number of carbons	Uses
		»Refinery gas		1-4	Bottled gas, fuels
		»Petrol	40	~8	Fuel for cars
		»Naptha	110	~10	Raw material for chemicals and plastics.
		»Kerosine	180	~15	Fuel for Aeroplanes
		»Diesel	250	~20	Fuel for cars and lorries
		»Oils	340	~35	Fuel for Power Stations, Lubricants and grease
Hot crude »		»Bitumen	400+	40+	Road surfacing.

Oil Refinery

Oil Storage Container

Upstream - Midstream - Downstream

The upstream sector

The upstream sector involves the exploration for and extraction of petroleum crude oil and natural gas. The upstream oil sector is also known as the exploration and production (E&P) sector.
The upstream sector includes the searching for potential underground or underwater oil and gas fields, drilling of exploratory wells, and subsequently operating the wells that recover and bring the petroleum crude oil and/or raw natural gas to the surface.

The midstream sector

The midstream involves storing, marketing and transporting petroleum crude oil, natural gas, natural gas liquids (mainly ethane, propane and butane) and byproduct sulfur. Midstream operations are sometimes included in the downstream category.

The downstream sector

The downstream sector involves the refining of petroleum crude oil and the processing of raw natural gas. It includes the selling and distribution of processed natural gas and the products derived from petroleum crude oil such as liquified petroleum gas (LPG), gasoline (or petrol), jet fuel, diesel oil, other fuel oils, petroleum asphalt and petroleum coke.
The downstream sector includes petroleum refineries,^[1] petroleum product distribution, retail outlets and natural gas distribution companies.

Byproduct sulfur

Petroleum crude oil is a mixture of hundreds of hydrocarbons, many of which contain sulfur that is removed during the refining of the crude oil. Raw natural gas also has sulfur-containing compounds, which are removed in processing of the raw natural gas before it is distributed to consumers. The sulfur-containing compounds removed in the refining and processing of petroleum crude oil and raw natural gas are subsequently converted into byproduct elemental sulfur. The production and marketing of the byproduct sulfur is considered to be part of the downstream sector.
The vast majority of the 64,000,000 metric tons of sulfur produced worldwide in 2005 was byproduct sulphur from refineries and natural gas processing plants.^[2]

Petrochemical industry

The petrochemical industry is not generally considered to be a part of the petroleum industry. However, it is sometimes listed as a part of the downstream sector and sometimes as a fourth sector of the petroleum industry.
