Co – is a free business resource network and community to help professionals learn and grow. The official number of immediate deaths was The second mitigation step is a vent gas scrubber. They were of MIC, Chlorine, phosgene, carbon tetrachloride, mono methyl amine. The people started to wake up when the gas started to suffocate them. This includes the MIC storage tank refrigeration system which could prevent this disaster.

The main problem is that the temperature could increase quickly to about C. UCIL produced pesticides and agricultural product s to cover the huge demand of Indian market. There was no warning or any emergency plan to evacuate the people as soon as possible. Investigations done later indicate that about lb of water entered the tank. When they returned after two hours, it was too late. It has a highly active volatile reaction with water. This will result in the boiling of unreacted MIC.

The operators assumed that owing to bad maintenance and leaking valves, it was possible for the water to leak shudy the traagedy. The affected area was about 40 sq km. UCIL produced pesticides and agricultural product s to cover the huge demand of Indian market.

This incident is considered the worst industrial disaster in the world. In this scrubber the gas entering from its lower part is sprayed by caustic soda solution which can neutralize the MIC and convert it to harmless material.

Several factors contribute to cause such a huge disaster, such as: The official number of immediate deaths was The boiling point of the MIC is around The flare system was out of service.

Other references stated that among the people, who were exposed to gas, people died, injured, continue to suffer of bad health effects. According to the operators, the pressure gage of the MIC tank had been malfunctioning for a week.

These reactions will be catalyzed and be faster in case of existence of Iron oxides as happened in the day of disaster. Intwo trade unions complained about pollution in the plant[4]. In closed system these reactions could increase the pressure in great manner. Co – is a free business resource network and community to help professionals learn and grow.

Bhopal gas tragedy – US court rejects case against Union Carbide. Figure 8 Flow sheet of the mitigation process For me as a chemical engineer the above mitigation process is a wonderful one. The scrubber failed, and the water curtain was not high enough.

For sure lives have been saved. Nitrogen or inert padding is commonly used in tanks holding volatile fuels or reactive chemicals.

At the time of the disaster only six of the twelve operators were cas working and the number of the supervisors was reduced to the half. Log In Sign Up.

There was no storage tank between the large storage container and the MIC production unit to check its purity. In summery there were a lot of gaps in the way of understanding of this case, but risk analysis studies enable as to extract the most probable scenario.

The operator switched on the the vent gas scrubber and the water curtain sprinkler to neutralize the released gas. Enter the email address you signed up with and we’ll email you a reset link.

No information was given to the local authorities about the huge quantities of dangerous chemicals used and manufactured in the plant. The only thing done for most of those poor people csse drops in their eye. Poor management systems 2.

There should be slip blind plates that could prevent cleaning water in the pipes from entering the MIC tank in case the valves were faulty.

At that time the plant was considered as a part of green revolution in India,as it clear in the poster below. These first steps led to a change in the practice and education of studg engineers in the US and Europe.

But the gages were not trustful due to bad maintenance for a long period of time. Many workers run away out of the plant escaping from the gas. Due to the conflict between Indian government and Union Carbide Corporation about the responsibility of what happened.

The following diagram is for the tank and after tank safety features [3 ].
