Abstract: An insertion apparatus is provided for inserting at least one catalytic insert into each of a multiplicity of reactor channels. The apparatus includes a magazine configured to locate a multiplicity of catalytic inserts, a guide element for guiding the movement of a catalytic insert as it is inserted into the reaction channel, and a pushing member to push a catalytic insert out of the magazine, through the guide element, and into a reactor channel. An automated method for inserting catalytic inserts into reactor channels is also provided. The method includes the steps of: aligning the insert with a reaction channel, and pushing the insert through a guide element into the channel.

Abstract: A plant is provided for processing natural gas. The plant comprises two or more modules connected in parallel. The plant is configured to convert the associated gas into a material with a higher density. In addition, a method of processing gas associated with one or more oil wells. The method comprises the steps of: providing a modular plant comprising two or more modules in parallel wherein at least one of the modules is a robust module and at least one of the modules is an economical module; turning down one or more of the modules when productivity drops; switching off one or more of the modules at least when productivity drops beyond the turndown limit. The natural gas is treated in a Fischer-Tropsch unit.
