Hyundai Engineering / Hyundai Engineering Co. LTD is a separate entity and not the same as Hyundai Engineering & Construction . Common mistakes arise when looking at their logos because it is almost the same but below the Pyramid of the Logo you would noticed the distinctions. Though Hyundai Engineering had been part of the Hyundai Engineering & Construction on May 1999 but after 2 years the Hyundai Engineering gains its independence and were recognized as a separate entity from Hyundai Engineering & Construction in July 2001.Established in 1974, Hyundai Engineering Co., Ltd. has accumulated project experiences and technologies in more than 50 countries for the business area of Process Plant, Power & Energy Plant, Infrastructure & environmental and Industrial Plant.In spite of Hyundai Engineering 's separation from Hyundai Engineering & Construction, they become re-united because they were both member of the Hyundai E&C GroupKIM, Dong Wook -is a President and CEO of Hyundai Engineering Co. Ltd since March 1999 until June 30, 2011. Kim has resigned and replaced with the new President and CEO KIM, Wee Chul from July 1, 2011 to the present. Wikipedia.

Disclosed herein is an apparatus for continuously producing and pelletizing gas hydrates. The apparatus includes a gas supply unit, a water supply unit and a reactor. Gas and water are respectively supplied from the gas supply unit and the water supply unit into the reactor. The gas and water react with each other in the reactor. The reactor includes a dual cylinder unit which forms a gas hydrate in such a way as to squeeze a slurry of reaction water formed by the reaction between the gas and water. The dual cylinder unit includes an upper cylinder, a lower cylinder and a connection pipe which connects the upper cylinder to the lower cylinder. The connection pipe has passing holes through which the reaction water in the reactor flows into and out of the connection pipe.

The present invention relates to a high-strength silicoaluminophasphate-34 (SAPO-34) microsphere catalyst, a method for preparing the same, and a method for preparing light olefins by using the same, and when described in more detail, the present invention relates to a method for preparing a SAPO-34 microsphere catalyst, including: spray drying a mixed slurry including a matrix, a binder, an additive, and the like to a SAPO-34 slurry prepared by a hydrothermal synthesizing method using various organic templates such as tetraethylammonium hydroxide (TEAOH), and the like alone or in mixtures to prepare microspheres, and firing the microspheres, and to a SAPO-34 microsphere catalyst for a circulating-fluidized bed reactor, prepared by the preparation method. The SAPO-34 microsphere catalyst of the present invention has excellent reaction activity while having high strength, and thus is appropriate for use in a circulating-fluidized bed reactor requiring high strength of the catalyst. Further, the SAPO-34 microsphere catalyst has a long life-span and excellent conversion rate of C

Disclosed herein is an apparatus and method for continuously producing and dehydrating gas hydrates. The apparatus includes a gas source, a water source, a reactor, a spinning wheel, and a centrifugal separator. The gas source and the water source are connected to the reactor. Gas and water are respectively supplied from the gas source and the water source into the reactor and react with each other in the reactor to form gas hydrate slurry. The spinning wheel and the centrifugal separator are provided in the reactor. The spinning wheel supplies the formed gas hydrate slurry to the centrifugal separator. The centrifugal separator dehydrates the gas hydrate slurry. Water removed from the gas hydrate slurry by the dehydration of the centrifugal separator is re-supplied into the reactor.

The present invention relates to a system for remediating highly contaminated fine soil using multiple micro hydrocyclones that includes: a mill adapted to mix contaminated soil with water and to individualize the soil; a screen adapted to separate the soil introduced from the mill into soil having given particle sizes; a separator adapted to finely separate the soil having particle sizes of less than a given value by particle size from the soil having the given particle sizes separated through the screen; a remediating unit adapted to wash the finely separated soil introduced from the separator by particle size by means of process water for washing; and a filtering unit adapted to separately discharge the soil washed and introduced through the remediating unit and the process water for washing contained in the soil.

The present invention relates to a tunnel reinforcement structure capable of controlling ground displacement using pressurization, including: reinforcements adapted to be forcedly inserted into the bored holes formed along the outer surface of the section to be excavated of the tunnel; auxiliary reinforcements disposed between the reinforcements from a point between 4 m and 8 m inwardly from the ends of the reinforcements; steel ribs disposed on the inner four faces of the excavation face of the tunnel; pressurizing bags each provided between the steel ribs and the excavated inner surface of the tunnel; a concrete part adapted to be cast between the steel ribs; and lining concrete adapted to be cast to the steel ribs and the inner surface of the concrete part.
