Since you have some additional solution, I would suggest adding one-half of your required K-meta and re-testing. It will help keep you from accidental overdose, and allow you to verify your readings and calculations before your

  • Simulation and assessment of SO2 toxic environment after

    Jun 15, 2010To study the sulfur dioxide (SO 2) toxic environment after the ignition of uncontrolled sour gas flow of well blowout, we propose an integrated model to simulate the accident scenario and assess the consequences of SO 2 poisoning. The accident simulation is carried out based on computational fluid dynamics (CFD), which is composed of well blowout dynamics, combustion of sour gas, and products
