PLGA-1000

프로세스 레이저 가스 분석기

석유화학 플랜트 제조 공정의 생산성 향상에 기여하는 새로운 측정 솔루션*

프로세스 레이저 가스 분석기는 석유화학 공장의 프로세스 가스에 포함된 탄화수소 및 기타 가스를 측정하도록 설계되었습니다.

PLGA-1000은 자체 기술을 활용해 고농도 메탄(CH₄)과 에탄(C₂H6)내의 불순물로 포함된 저농도 아세틸렌(C₂H₂)과 이산화탄소(CO₂)를 연속적으로 고속, 고감도로 측정합니다. 이는 생산 공정의 생산성, 비용절감 및 품질 향상과 환경 영향 감소에 기여합니다.

Delivering New Benefits with Innovative Technology

HORIBA's proprietary IRLAM™ *¹ (InfraRed Laser Absorption Modulation) technology realizes new solutions for specific manufacturing process that have been difficult to achieve with process gas chromatograph measurements.

Significant Improvement of Process Control With More Accurate and High-Speed Stable Continuous Gas Measurement

Continuous measurement of low-concentration impurity gas in high concentration hydrocarbons accurately in a short measurement time.

- High sensitivity measurement: ppb level (Low concentration impurities in high concentration hydrocarbons are measured at ppb level.)

- Fast response time: 3 seconds (for details, see response time in specifications)

Operational Cost Reduction

A column-free gas analyzer that uses IRLAM technology. Furthermore, the frequency of replacement parts and calibration is reduced by using a laser as the light source.

Compact Installation Area

The use of a small gas cell (Herriot cell), etc. reduces the footprint of the analyzer and contributes to save your space.

Measurement Principle

HORIBA’s Proprietary IRLAM Technology

HORIBA's proprietary IRLAM technology consists of three new technologies with distinctive features. These key components are developed and produced in-house which allows us to address to diverse customers' needs.
