Hence these are not repeated for each such scenarios. Flammable Effect: Atmospheric Stability Class D Atmospheric Stability Class F Discussion: The discharge rate through leak is 1.23kg/s.The total material released is 1221kgs. The evaporating pool will release MIBK vapors to atmosphere which will disperse in downwind direction. If the dispersed vapors got ignition then a fire will flash back to source and pool fire will sustained. The total material will burnt out in 6mins. Although for atmospheric stability class F, the temp (10degC) is below flash point of MIBK (14degC), the consequence is calculated considering the fire initiated due to other source. In case of stability class D/F,radiation of 37.5kw/m2 is experienced up to distance 14/less than 10m respectively. But the total spilled material will be burnt within 6 mins. 4.0 & 1.6 kw/m2 distances are 29 & 39m for atmosphere condition D and 27 & 42m for F. Siddhi Green Excellence Pvt.

There can be 10 events of handling. Due to damage total material of the drum is spilled on the ground. Due to the adjacent drums the pool height is considered as 10mm.Hence the pool area is considered as 20m2. The consequence is evaluated assuming that the spill will get an ignition immediately. Flammable Effect: Atmospheric Stability Class D Atmospheric Stability Class F Discussion: The pool fire due to this spill will last for 3mins and all 175kgs of spilled ETHYL ACETATE will burn within this time. The burn rate is 1.09kg/s. The radiation of 37.5kw/m2 will not experienced due to this fire. Due to these reasons there is unlikely that other drums will get damaged and additional ETHYL ACETATE will be spilled. If the explosive mixture is not ignited immediately then the spilled material will be evaporated at rate of 0.29kg/s and it will take 16 mins to evaporate all the spilled material.

The concentration at this point will be 333ppm for 1-2 mins and subsequently it decreases below IDLH value.(as seen in below fig) A part of the emergency plan considers the evacuation of (parts of) the plant, the neighboring plants and people in further surroundings to minimize exposure in case of an Acrylonitrile vapour cloud ACN detectors can be installed at the strategic locations in the plant and battery limit which helps in alarming that ACN is escaping to offsite. To minimize the effects it is suggested that the area where ACN is handled may have bund wall of 300mm.This will limit the spread of ACN spill and reduce the pool area. Eventually evaporation rate and ACN evaporated & released to air can be minimized. If the dispersed vapors got ignition then a fire will flash back to source and pool fire will sustained. The total material will burnt out in 8mins. 4.0 & 1.6 kw/m2 distances are 23 & 31m for atmosphere condition D and 24 & 36 m for F. ACN is Highly reactive and reacts violently with strong oxidising agents.acn emits toxic fumes of hydrogen cyanide and nitrogen oxide when heated to decomposition. In the event of a fire involving acrylonitrile, use alcohol resistant foam, or normal foam if not available, and liquid tight protective clothing with breathing apparatus Siddhi Green Excellence Pvt.

There can be 50 events of handling. Due to damage total material of the drum is spilled on the ground. Due to the adjacent drums the pool height is considered as 10mm.Hence the pool area is considered as 20m2. The consequence is evaluated assuming that the spill will get an ignition immediately. Flammable Effect: Atmospheric Stability class D At 10degCatmospheric temperature, ethylene diamine is near to solidification state(mp 8.5degC) hence it will solidify once released to atmosphere. Hence no hazardous scenario will be created. It can be handled as per normal plant practices. Discussion: The pool fire due to this spill will last for 4mins and all 175kgs of spilled Ethylene Diamine will burn within this time. The burn rate is 0.65kg/s. The radiation of 37.5kw/m2 will not experienced due to this fire. Due to these reasons there is unlikely that other drums will get damaged and additional Ethylene Diamine will be spilled.

The 50% of reactor volume contains hydrogen which is available for explosion. The release will catch fire immediately as MIE of hydrogen is very less (0.017mJ) and result in explosion. Total released material is 10.7 kg. Flammable Effect (Explosion): Atmospheric Stability Class D Atmospheric Stability Class F Discussion: The failure of hydrogenation reactor will result in release of reactants and the content will splash with force exerted due to 100barg pressure. Almost instantaneously the released hydrogen will explode as hydrogen do not need any separate ignition source as its required minimum ignition energy is very low (0.017mJ). The explosion will result in overpressure. The analysis results shows that overpressure wave more than 8psi will not be experienced. At distance of 24/75 m, the overpressure experienced is 0.5psi for stability class D/F respectively.it can cause injuries due to glass shattering of windows.

Leak is from instrument tubing which is disconnected and of size ¾. The leak will cat fire immediately as MIE of hydrogen is very less(0.017mj).a jet fire will sustain at the leak. The leak is assumed to be for 15mins before detection and isolation. Flammable Effect Explosion No Explosion Atmospheric Stability Class D Atmospheric Stability Class F Discussion: At the release rate of & kg/s for stability class D & F.The burning will occur and it will end within 20 secs (completely burning 1.08 / 1.22 kgs in one cylinder). At this rate the radiation effect of Jet Fire are maximum. All radiation effects are within less than 10m from jet source. The flame length is 1m at start. This is due to high pressure inside of the cylinder. Practically it will take more time but with less release rate. As pressure will reduce inside cylinder the release rate will also reduced. In case of stability class F, the explosion effects are also experienced.0.5 psi overpressure is experienced upto 25m.This overpressure can shatter glasses. Siddhi Green Excellence Pvt.

There is certain volume over the pool whose composition can be found out by vapor pressure (0.34psi) of formaldehyde solution at ambient conditions. This formaldehyde is available for dispersion. It can be modeled as direct source in ALOHA as instantaneous release. 2. The emission rates of formaldehyde from 37% solution are available in literature. (Ref: Estimating Formaldehyde Emission in Air by EPA;1991) For different process and storages rates are reported. Maximum of these rates (0.35kg/Mg) can be used in ALOHA and modeled in ALOHA as direct source with continuous rate. Based on vapor pressure,on conservative side it is assumed that from the released solution 2.5% of the amount of formaldehyde gas is released to atmosphere. The release rate of formaldehyde gas : 1.44*0.37*2.5% = kg/s This much formaldehyde is available to disperse in downwind direction.it is modeled as direct source - continuous in ALOHA.

Estate, Jolva, District Bharuch, Gujarat, India Toxic Effect: The Area is patchy hence not shown. Atmospheric Stability Class D Atmospheric Stability Class F Discussion: It is assumed that after isolation and control of the formaldehyde solution leak(ie 15mins) still there will be release of formaldehyde gas from spilled solution but it is assumed that it will be negligible as all 37% formaldehyde is released during the leak. The IDLH distance for stability class D & F is 45 and 162m. For atmospheric class D the area of dispersion is not wide and it is patchy,hence ALOHA has not given the map. For class F also the spread of area along the line of concentration is not more than 5m. At these distances the horizontal spread of vapour cloud is not more than 10m maximum. The toxic effect is more severe than flammable effects. Siddhi Green Excellence Pvt. Ltd., Ankleshwar Page 21 of 24
