Title:
オンライン水晶微量天秤センサーを用いた、石油及び石油化学プロセスにおける化学物質処理の監視及び制御方法
Document Type and Number:
Japanese Patent JP3876293
Kind Code:
B2
Abstract:
Thickness-shear mode resonators which simultaneously measure mass deposition and fluid properties can be utilized to monitor petroleum processing, petrochemical and water treatment systems. Specialty chemical additive materials can be accurately and instantaneously added to control conditions detected by the thickness-shear mode resonators. The thickness-shear mode resonators are piezoelectric crystals used in conjunction with oscillator circuitry that can determine mass as well as viscosity and/or density of a fluid in contact with the piezoelectric surface.
