New Gaschromatograph MGCdirect brings significant emission reduction paired with faster response time

The gas chro­ma­to­graphs (PGCs) from meterQ can be used for any mea­su­re­ment sce­na­rio up to and inclu­ding Ex Zone 1, for cus­t­ody trans­fer and nor­mal pro­cess mea­su­re­ments of natu­ral gas, bio­gas, hydro­gen and natu­ral gas hydro­gen mix­tures. This also appli­es when cus­t­ody trans­fer gas ana­ly­sis is requi­red to meet the ever lou­der demands for the reduc­tion of cli­ma­te-dama­ging natu­ral gas emis­si­ons. With the MGCdirectmeterQ now mana­ges to redu­ce emis­si­ons by a fac­tor of 10 com­pared to an avera­ge PGC instal­la­ti­on. The com­pact mea­su­ring sys­tem of the MGC series is moun­ted as a trans­mit­ter in a small wea­ther­pro­of box direct­ly abo­ve the tap­ping point on the pipe­line, which means that the­re is no distance bet­ween the ana­ly­zer and the gas line. This con­di­ti­ons are ide­al for fast-respon­se mea­su­re­ment. In the inte­rest of cli­ma­te pro­tec­tion, a spe­cial sam­pling sys­tem is used that trans­ports the gas nee­ded for ana­ly­sis to the pres­su­re reduc­tion unit and feeds the rest of the gas back into the pipe via a dou­ble wal­led sam­pling pro­be. In this respect, the gas exch­an­ge takes place very quick­ly. The loop in turn makes it pos­si­ble to dis­pen­se with a bypass. Com­pared to con­ven­tio­nal PGCs, this leads to a 95% reduc­tion in pro­cess gas emis­si­ons.

In addi­ti­on to that, the con­cept offers users a very fast respon­se time with regard to chan­ges in gas qua­li­ty. This makes the device sui­ta­ble for all sce­na­ri­os in which rapid detec­tion of chan­ges in gas qua­li­ty is essen­ti­al.

No special analyzer shelter necessary

Ano­ther advan­ta­ge over clas­sic instal­la­ti­ons is that a spe­cial ana­ly­zer house is no lon­ger requi­red for use. Only the ope­ra­ting gases (car­ri­er gas and cali­bra­ti­on gas) need to be available in the vici­ni­ty of the MGCdirect. For indoor instal­la­ti­ons, a con­ven­tio­nal gas sup­p­ly unit is suf­fi­ci­ent for this pur­po­se. For out­door designs, a hea­ted cabi­net and a hea­ted cali­bra­ti­on gas line are requi­red. It eli­mi­na­tes the need for the typi­cal­ly much lon­ger hea­ted sam­ple gas line in clas­sic instal­la­ti­ons. Bet­ween cabi­net and elec­tri­cal room, only the lay­ing of one Ether­net cable is neces­sa­ry.
