How to shuck an oyster? This method of oyster shucking is often used by restaurants for presentation purposes. Hold the oyster cup side down, flat side up, with the hinged or narrow end in your hand. Insert the knife about 1/3 back from the wide end of the oyster. Go in using the knife and cut the muscle. Be careful to keep your fingers out of the path of the knife. Detach the muscle from the bottom shell. Carefully roll the meat over, taking care to neatly detach the muscle underneath.

Subject field(s)
  • Petroleum Distillation
CONT

The Shell Middle Distillate Synthesis(SMDS) plant now operational at Bintulu, Malaysia, is the latest in a series of partnership projects between Shell companies and the people of Malaysia that stretches back for more than 100 years. The new plant uses advanced technology to convert natural gas, abundantly available from the Central Luconia field offshore Sarawak, into liquid fuels of high purity. These fuels can also be used as components to upgrade lower quality stock derived from conventional crude oil processing. In addition, the plant can produce high-value waxes, as well as feedstocks for detergents and lubricants. The product mix can be varied to meet market needs. The SMDS technology was developed at the Shell laboratory in Amsterdam(KSLA) over a period of 20 years. After commercial and technical assessment, Bintulu was chosen in preference to sites in other parts of the world as an appropriate location for the employment of SMDS technology in the first commercial plant.

CONT

February 2003, Royal Dutch Shell (Netherlands) announced its plans to build two GTL facilities with a combined capacity of 75 000 bbls/d. QP is looking to employ Shell’s middle distillates synthesis (SDMS) technology to convert gas into diesel and kerosene.

... the helmet consists of two sections : an inner helmet with integral headphones and boom microphone; and an outer leather cover or ballistic shell. The inner shell is mainly made from Nomex, a fire-resistant material that scorches away when it gets too hot, rather than burning or melting, and has padding to cushion impacts against the top and back of the skull. Both the leather cover and the ballistic shell have a padded section at the front to protect the wearer's forehead from impacts. With the ballistic shell, the helmet is generally known as the "CVC" helmet, for "Combat Vehicle Crew;"...

Back Cover Subsystem(BCSS). The Back Cover protects the DM [descent module] during entry, ensures depressurisation during launch and carries multi-layer insulation(MLI) for the cruise and coast phases. Since it does not have to meet stringent aerothermodynamic requirements, it is a stiffened aluminium shell of minimal mass(11. 4 kg) protected by Prosial(5 kg). It includes : an access door for late access during integration and for forced-air ground cooling of the Probe; a break-out patch through which the first(drogue) parachute is fired; a labyrinth sealing joint with the Front Shield, providing a non-structural thermal and particulate barrier.

A horizontal, fire-tube boiler in which the flue gases are passed back and forth through the boiler shell 2 or more times by means of a tube arrangement or baffles. Each change in direction is called a pass. In order to maintain the flue gas velocity, each succeeding pass is reduced in total cross section to compensate for the reduced flue gas volume as the gases cool.

  • Steam-Powered Machines and Condensers
DEF

Fluid-fluid heat exchanger made of two concentric pipe sections; one fluid (such as a coolant) flows in the annular space between pipes, and the other fluid (such as hot process stream) flows through the inner pipe.

CONT

The condenser is also a Model no. 06036 shell and tube exchanger, identical to the reboiler with a few modifications : The baffles have been cut at the bottom where they meet the shell to allow condensate to flow out of the shell. The tube side has four passes for maximum heat transfer on the tube side. It is mounted nearly horizontally. The inlet end is a couple of inches higher than the outlet to allow condensate to drain out the low end. A few tubes have been removed at the top to give the vapor more room to distribute itself along the length of the shell. There is a vent on the shell side near the outlet end to allow non-condensable gases to leave. The vent gases pass through the inside of a 36" double pipe condenser so that any condensable gasses will condense out and run down the walls back into the condenser.

Subject field(s)
  • Electrotyping and Stereotype Printing
CONT

Readying the electrotype shell. The metal layer deposited on the mould is called a shell and is 2/10 to 4/10 of a mm in thickness(8/1000 to 16/1000 of an inch)... The thickness is in function of the amount of time given to the process of electrolysis. Once the desired thickness is achieved the shell must be detached from the mould. This is not always an easy matter. If the mould is made of wax it can be removed with boiling water... Plastic moulds are removed by pulling them off, and lead moulds must be cut away along the edges. Shells are fragile and as they are not rigid they are sometimes damaged when being removed from the mould. In any case, shells must be backed to make them hard enough to print with. Backing is usually done by pouring a molten alloy made of lead(97%) and antimony(3%) onto the back of the shell.
