South Pars Annual Production of Odorant to Reach 2,000 Tons 

The project to build a gas condensate concentration unit at the third refinery of South Pars Gas Field for feeding the mercaptan unit is underway, which will raise the annual output of gas odorants to 2,000 tons, the director of refining projects at the Iranian Gas Engineering and Development Company said.
“Odorant is added to natural gas for detecting leaks in the gas pressure reduction stations,” the Oil Ministry’s news agency Shana also quoted Ebrahim Esalati as saying.
Mercaptan, also known as methanethiol, is an organic gas composed of carbon, hydrogen and sulfur. It bonds strongly with mercury compounds and releases a strong odor resembling that of garlic or rotting cabbage.
