A method of constructing a coil wound heat exchange module and transporting and installing the coil wound heat exchange module at a plant site, such as an natural gas liquefaction plant. A module frame is constructed and attached to a heat exchanger shell prior to telescoping of a coil wound mandrel into the shell. The module frame includes a lug and two saddles that remain attached to the shell throughout the process and when the heat exchanger is operated. The lug and saddles are constructed and located to stabilize the shell during construction, telescoping and transport (when in a horizontal orientation), and when the shell is installed at the plant site (in a vertical orientation). The lugs and saddles are adapted to allow for thermal expansion and contraction of the shell when it is transitioned from ambient to operating temperature and vice versa.

The present invention relates to a method and system for producing liquefied natural gas (LNG) from a stream of pressurized natural gas which involves a combination of mechanical refrigeration.

A direct heat exchange and material transfer apparatus having a plurality of columns, a single stack of at least two solid metal plates of rectangular section, the plates being substantially all of the same shape and dimensions and parallel to a determined direction, each plate being separated from the adjacent plate, at least in a first direct heat exchange and material transfer zone of the apparatus, by a group of hollow metal columns that are aligned and have a section which is polygonal and has at least two parallel surfaces, the channels being parallel to the determined direction and contiguous with one another, the columns of each group each being in contact with the two metal plates on either side of the group, at least some of the columns of a group containing a material and heat exchange means.

One object of the present invention is to provide a compact multistage liquid storage-type condenser-evaporator capable of producing two kinds of gases having different compositions without increasing power, and a nitrogen production device using the multistage liquid storage-type condenser-evaporator without increasing the power for producing nitrogen, and the present invention provides a multistage liquid storage-type condenser-evaporator including a bottom liquid storage section which is configured to store the liquid supplied into the bottom evaporation passage without circulating, and a fluid collection section which is configured to collect the fluid which flows out from the bottom evaporation passage and discharge to the outside without returning into the bottom liquid storage section.

This specification relates to operating industrial facilities, for example, crude oil refining facilities or other industrial facilities that include operating plants that process natural gas or recover natural gas liquids.

Embodiments of a krypton recovery method and apparatus are provided. The method and apparatus involves removing contaminants from a krypton containing waste gas to yield a krypton containing effluent gas; compressing and cooling the krypton containing effluent gas to yield a nearly saturated vapor krypton containing effluent. The krypton containing vapor effluent.is partially condensed in a reboiler and the resulting stream is rectified in a crude distillation column to yield the crude krypton. The crude krypton to further refined is a separate cryogenic distillation system and process to produce a refined krypton product.
