http://slidepdf.com/reader/full/hp-gas-processes-hb-2012 1/2

This essential industry handbook contains flow diagrams

and descriptions of more than 130 commercially viable

gas processing technologies from 50 licensors. Featured

developments include drying, treating, contaminantremoval, cleanup, hydrogen, liquefied natural gas,

syngas, sulfur and gas-to-liquids. Each process description

includes a four-color flow diagram, as well as application,

operation, economic yield and licensor information. The

processes are indexed by process and contributing company.

This valuable reference tool should be available to every

engineer in the natural gas industry and will be distributed to all

paid subscribers of Hydrocarbon Processing magazine in specific

industries. Closing date for sponsorship is June 1, 2012.

Special supplement printed in September 2012

Nitrogen recycle LNG liquefer 

Application: Liquefaction of natural gas for peak shaving, product distri-bution or floating production storage and offloading (FPSO) applications.

Description: Natural gas is pretreated to remove water and carbon diox-ide (CO2). A fraction of the pretreated natural gas is used to regeneratethe CO2 /water (H2O) removal system. The remaining gas is cooled andthe heavier hydrocarbons (HC) removed in a knock-out (KO) drum ormulti-stage separation device. The resulting vapor product is then con-densed to produce LNG. Boil-off gas (BOG) from the LNG storage andthe collected heavier HCs are warmed in the exchangers and mixed withthe CO2 /H2O-laden regeneration gas. The resulting gas stream is thenreturned to the feed gas supply or a low-pressure fuel system.

Cooling is provided by a nitrogen (N2) recycle refrigeration system,which utilizes an N2 recycle compressor, an N2 compander and a cold boxthat houses the liquefaction heat exchangers. N 2 is compressed in the N2 recycle compressor and cooled in an aftercooler. A compander incorporatesa compression stage and an expansion stage on a single shaft. N2 droppingfrom high to low pressure across the expander wheel provides refrigerationand generates rotational force which is absorbed by the compressor wheelproviding a portion of the total nitrogen compression required. A portion ofthe N2 stream is expanded in the compander, providing part of the refrig-eration requirement. The remaining N2 is expanded with an expansion valveand provides the rest of the refrigeration required for liquefaction.

There are many variations in the specific configuration of the N 2 refrigeration cycle (pressures, number of expanders, expander arrange-ments, etc.). The configuration is driven by the need to develop the mostcost-effective solution for the plant size, final refrigeration temperaturerequired and project-specific economic evaluation criteria.

Economics: N2 recycle plants typically offer a lower capital solution forsmall plant applications and provide an attractive liquefication process op-tion for applications where hydrocarbon refrigerants may be undesirable.

Installations: Two units in operation in peak-shaving applications. Sixnitrogen recycle units under construction for LNG subcooling.
