Patent number: 10458597Abstract: The present invention is related to a corner panel of an LNG cargo that includes a main body, which constitutes a corner area of the cargo, and a stress diverging part, which reduces the convergence of stress of the main body by being integrated with an internal face of the main body and being formed with curvature. Therefore, by forming the corner area of the LNG cargo in a single body having a round-shaped curvature, convergence of stress caused by the deformation of the hull and thermal deformation can be prevented, and possibility of crack in a secondary barrier can be removed. By allowing the secondary barrier to be formed in a curved shape, the constructability of the secondary barrier can be greatly improved. Since no hardwood key or plywood is required, the thickness of a primary barrier can be reduced as the stress is decreased and the reliability of the secondary barrier is improved, and the weight can be greatly reduced over the conventional cargo corner area.Type: GrantFiled: October 20, 2016Date of Patent: October 29, 2019Assignee: SAMSUNG HEAVY IND.

Patent number: 5723838Abstract: Electron beam irradiation step is followed by alkaline material atomizing step in the present invention. Since irradiation step and alkaline material atomizing step is conducted in different time and in different reactors, the construction cost of X-ray shielding concrete is decreased remarkably. If the humidity of incinerator effluent gas is more than 100 g/Nm.sup.3 in dry basis by adding a steam of 110.degree..about.200.degree. C., harmful substances are efficiently removed by electron beam irradiation. As a result, it is possible to realize a space-saving equipment, a reduction of required energy, a simple operation controlling, and a prevention of occurrence of secondary environment pollution.Type: GrantFiled: September 26, 1996Date of Patent: March 3, 1998Assignees: Samsung Engineering Co., Ltd., Samsung Heavy Industries Co., Ltd.Inventors: Byung-chul Shin, Keun-hoo Lee, Bum-Soo Han, Ki-Hun Joh
