Sodium Hydrosulfide (NaSH)-An Alternative to Sulfur Production

05/18/2017 By Richard Neylon

Introduction Sodium Hydrosulfide (NaSH) solution is an alternative product to sulfur from hydrogen sulfide. Much hydrogen sulfide ends up on solid bed medias such as iron sponge or Sulfatreat®. This is disposed of in landfills. These processes are justified in most cases. Depending on your production rate of hydrogen sulfide, a Claus Unit may be just what you need. … [Read more...]

Hydrogen Sulfide Removal from Refinery Gas Streams

04/04/2017 By Shackeh Mastian

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 … [Read more...]

Process Hazard Analysis Issues and Solutions

09/13/2016 By R.C. Costello

Considering the complexity and volatile nature of today’s chemical processes, Process Hazard Analysis (PHA) studies are necessary for risk management of highly hazardous process systems. Hazardous chemical facilities have a responsibility to protect people and their environment, as well as property. The best option for completing a PHA is to find experienced specialists who … [Read more...]
