System GC Solution for Refinery Gas Analysis
Gas compositions produced in refinery plants consist of hydrocarbons, permanent gases, H2S, etc. Analyzing these gases is essential to control the quality of chemical products and plant operation. Shimadzu’s RGA systems, available in numerous configurations, are designed to analyze various compositions in a variety of processes. In research and development for petrochemical and its catalysis field, target compounds often contain high-boiling point compounds and isomers. The Shimadzu CERGA makes it possible to precisely analyze those samples. In addition, calorific value calculation software is compliant with various calculation methods such as BTU and ISO-6976
Transformer Oil Gas Analysis System (TOGA)
It is necessary to analyze outgas in transformer insulation oil in power plant facilities. Shimadzu offers a System GC compliant with ASTM D 3612 Method B (oil stripper sampling) or ASTM D 3612 Method C (headspace sampling). The GC-2014TOGAS3 system, equipped with a PDD, enables the analysis of more trace amounts of permanent gas than conventional systems.
Town Gas Analysis System
Periodical monitoring of calorific values is necessary to ensure a stable supply of town gas. Since Shimadzu’s system GC is robust and designed for automated analysis, it is widely used for 24 hour/day online analysis in this field. Dedicated software is able to calculate calorific values and indexes automatically. Using the sample line selctor SLS-2020, a single system GC can analyse multiple samples without switching the sample line. This saves both running and initial costs.
Downstream and Others
A gas chromatograph is used for impurity analysis of intermediate or final products in various chemical fields. The table below shows our System GC lineup
Tracera UFRGA Series
The Tracera Ultrafast RGA system utilizes the new Barrier Discharge Ionization Detector (BID) technology coupled with a GC-2010 Plus capillary gas chromatograph to create new system GC for ultrafast, high-sensitivity analysis. Since the electrode creating Helium plasma is totally isolated from the carrier gas, there is no chance to contaminate this electrode with a dirty sample. This enables long-term stability.
Distillation Gas Chromatograph System
The Shimadzu simulated distillation system, consisting of a GC-2010 Plus high-performance capillary gas chromatograph and LabSolutions simulated distillation GC analysis software, meets all applicable ASTM, ISO, EN, and JIS standards. Permitting accurate and highly reproducible analysis of high-boiling components in crude oil samples, it is the optimal system for product quality control and process management in oil refinery plants.
