Bottom Ash
Constitutes about 10% – 15% of the overall ash, has an appearance similar to dark gray coarse sand and its particles are clusters of micron-sized granules, up to 10 mm in diameter
Bottom-supported offshore drilling rig
A type of mobile offshore drilling unit that has a part of its structure in contact with the seafloor when it is on site and drilling a well. The remainder of the rig is supported above the water. The rig can float, however, allowing it to be moved from one drill site to another. …
Brent crude oil
Brent Crude is one of the major classifications of oil. Brent Crude is sourced from the North Sea. Technically, it is a mix of crude from the UK Brent field and the Ninian field. The term Brent is the initials of 5 production layers: Broom, Rannoch, Elieve, Ness and Tarbat
Bioclimatic architecture; Green building; Zero net energy buildings
A way of designing and constructing buildings and manipulating the environment within buildings, taking into account climate and environmental conditions to help achieve thermal comfort, reduce the consumption of fossil fuel and cut electricity bills. Designs include optimum site selection (such as exposure to winter sun or summer breeze), use of building components for roof, …

Boil off
LNG that evaporates during storage and transport. Typically, any rise in temperature of LNG during storage and transport will be countered by allowing evaporated LNG to vent from storage tank. Boil off gas is sometimes used to supplement fuel for tankers, or as a fuel at storage facilities
Bottle type submersible rig
A mobile submersible drilling structure constructed of several steel cylinders, or bottles. When the bottles are flooded, the rig submerges and rests on the bottom; when water is removed from the bottles, the rig floats. Suitable for shallow drilling of about 30 m
Bottomhole pressure
The pressure usually measured in pounds per square inch (psi) at the bottom of the hole. Test that is carried out by a wireline service company, that lowers a pressure recorder down the tubing to record bottom hole pressure with the well shut-in over 24 hrs (namely leaving the recorder for 24hr to stabilize the …

Base load generation vs. peak load generation
A base load generation unit is one that provides a steady flow of power regardless of total power demand by the grid. This unit runs all seasons except during the time when repairs or scheduled maintenance occur. Base-load plants usually run on low-cost fuels such as coal and are massive enough to provide a majority …

Base load vs. Peak load storage of natural gas
There are two uses for natural gas in storage facilities: meeting base load requirements and meeting peak load requirements. Base load storage capacity is used to meet seasonal demand increases and is capable of holding enough natural gas to satisfy long term seasonal demand requirements. Typically, the turn-over rate for natural gas in these facilities …
