FAQ

Why does it make eco­no­mic sen­se to mea­su­re the metha­ne con­tent, and why is it even more advan­ta­ge­ous with TDLAS?

Measuring the metha­ne con­tent is cru­cial to ensu­re that your bio­me­tha­ne meets the requi­red qua­li­ty stan­dards - whe­ther for fee­ding into the natu­ral gas grid, use as a fuel or other appli­ca­ti­ons. Accurate mea­su­red values allow you to opti­mi­ze your pro­ces­ses, maxi­mi­ze metha­ne yield and redu­ce ope­ra­ting cos­ts. Inaccurate or delay­ed mea­su­re­ments, on the other hand, can lead to qua­li­ty los­ses, sys­tem mal­func­tions or addi­tio­nal cos­ts.

TDLAS tech­no­lo­gy offers decisi­ve eco­no­mic advan­ta­ges that other tech­no­lo­gies such as NDIR mea­su­re­ment tech­no­lo­gy do not achie­ve:

  1. Real-time mea­su­re­ments: With a mea­su­re­ment fre­quen­cy of up to one value per second, TDLAS pro­vi­des con­ti­nuous data that enables imme­dia­te adjus­t­ments to be made in your pro­ces­ses. This is a signi­fi­cant advan­ta­ge, espe­ci­al­ly in dyna­mic sys­tems such as metha­ne pro­ces­sing or feed-in.
  2. Greater accu­ra­cy and sta­bi­li­ty: While NDIR can gene­ral­ly be affec­ted by cross-sen­si­ti­vi­ties or opti­cal con­ta­mi­na­ti­on, TDLAS remains accu­ra­te even under deman­ding con­di­ti­ons. This redu­ces the need for cor­rec­tions and manu­al inter­ven­ti­on.
  3. Increased effi­ci­en­cy through pro­cess con­trol: Thanks to the rapid avai­la­bi­li­ty of data, you can iden­ti­fy pro­blems or fluc­tua­tions at an ear­ly stage and take coun­ter­me­a­su­res befo­re pro­duc­tion los­ses occur. This is often not pos­si­ble with slower tech­no­lo­gies.
  4. Ease of main­ten­an­ce: TDLAS requi­res less cali­bra­ti­on and no regu­lar fil­ter chan­ges, which saves time and money. In addi­ti­on, the­re are no mea­su­re­ment devia­ti­ons due to age­ing of opti­cal com­pon­ents.

What advan­ta­ges does TDLAS offer over other tech­no­lo­gies?

The laser-based TDLAS tech­no­lo­gy requi­res less main­ten­an­ce, deli­vers extre­me­ly pre­cise results and is cross-sen­si­ti­vi­ty-free. This redu­ces ope­ra­ting cos­ts and maxi­mi­zes the pro­duc­ti­vi­ty of your plant, espe­ci­al­ly in appli­ca­ti­ons with high metha­ne con­cen­tra­ti­ons. Compared to NDIR, TDLAS is more pre­cise and relia­ble, avo­i­ding errors and mini­mi­zing eco­no­mic los­ses.

How does the bio­me­tha­ne TDLAS con­tri­bu­te to long-term savings?

The high mea­su­ring accu­ra­cy and sta­bi­li­ty not only save you cali­bra­ti­on cos­ts, but also ope­ra­ting cos­ts through the effi­ci­ent use of your resour­ces. The low main­ten­an­ce requi­re­ments and the long ser­vice life of the com­pon­ents make the device an extre­me­ly eco­no­mic­al invest­ment.

Can I increase the metha­ne con­tent with the bio­me­tha­ne TDLAS?

Yes, pre­cise mea­su­re­ments of the metha­ne con­tent make it pos­si­ble to opti­mi­ze your pro­ces­ses and maxi­mi­ze the metha­ne yield. This increa­ses your reve­nue by pro­du­cing high-qua­li­ty bio­me­tha­ne.

What makes TDLAS par­ti­cu­lar­ly valuable for bio­gas plants?

TDLAS tech­no­lo­gy deli­vers relia­ble results, espe­ci­al­ly in appli­ca­ti­ons with high metha­ne con­cen­tra­ti­ons, wit­hout impu­ri­ties or cross-sen­si­ti­vi­ties affec­ting the mea­su­red values. This is cru­cial to ensu­re con­sis­tent qua­li­ty and effi­ci­en­cy.

Is the Gas Analyzer easy to use?

The intui­ti­ve touch dis­play allows you to moni­tor all important mea­su­re­ment data in real time. The robust design and mini­mal main­ten­an­ce requi­re­ments ensu­re that your sys­tem runs smooth­ly.

How does TDLAS tech­no­lo­gy dif­fer from NDIR mea­su­re­ment tech­no­lo­gy?

TDLAS tech­no­lo­gy uses laser-based spec­tro­sco­py to spe­ci­fi­cal­ly detect indi­vi­du­al mole­cu­les wit­hout cross-sen­si­ti­vi­ties. Compared to NDIR (non-disper­si­ve infrared spec­tro­sco­py) tech­no­lo­gy, TDLAS offers signi­fi­cant­ly more pre­cise results at high metha­ne con­cen­tra­ti­ons (80-100% by volu­me) and requi­res less main­ten­an­ce as the­re are no opti­cal fil­ters to foul. NDIR is more sui­ta­ble for lower con­cen­tra­ti­ons and appli­ca­ti­ons with less spe­ci­fic requi­re­ments.

What are the cali­bra­ti­on requi­re­ments for TDLAS?

TDLAS tech­no­lo­gy eli­mi­na­tes the need for regu­lar reca­li­bra­ti­on, as the auto­ma­tic zero point cor­rec­tion ensu­res long-term sta­ble mea­su­re­ments. This saves main­ten­an­ce time and cos­ts com­pared to other tech­no­lo­gies.

How quick­ly does the ana­ly­zer deli­ver mea­su­re­ment results?

TDLAS tech­no­lo­gy works almost in real time and has an inte­gra­ti­on time of 1 second. This enables pre­cise and fast adapt­a­ti­on of your pro­ces­ses.
