Part 2 of the Holl-Reactor® In this second installment of the Holl-Reactor®, we will discuss practical applications. Liquid-Liquid Reactions Mixing two liquid reactants is very typical. This is oftentimes done in a Continuously Stirred Tank Reactor (CSTR). Depending upon the physical properties of the two liquids, reaction times can be anywhere from minutes to hours. … [Read more...]
Hydrogen Sulfide Removal from Refinery Gas Streams
Hydrogen Sulfide (H2S) Hydrogen Sulfide (H2S) is a colorless, flammable and extremely dangerous gas. It is found in many refinery streams such as crude oil, asphalt, residual fuel, mid distillate, gasoline and blend components. As well as natural gas, propane and LPG. It is heavier than air and can travel along the ground. Protection Against H2S Exposure In concentration as … [Read more...]
Pressure Relief Valves and Flares for the Process Industries
1 Introduction Overpressure is caused by the accumulation of material or energy within a process system that exceeds the design conditions of the equipment. Relief of this overpressure in a plant is an ASME Code requirement and is necessary for loss minimization, energy conservation, and the protection of operating personnel, the public, the … [Read more...]
