| CORRELATION OF CONCENTRATION TO MASS FLOW RATE |


| An LDAR approach uses concentration as an indication
of the size of fugitive emission. By correlating this value to a mass flow rate, the amount of product lostcan be estimated. |
| Each emission reading is carefully stored in the specially designed LDAR Envolve 'cloud' database. |
| Within the database we are able to calculate the
level of lost product. Two leak values are given: one according to the Society of Organic Chemical Manufacturing Industry (SOCMI) and one according to Petroleum Industry Correlation. Both calculations are empirically based but yield different plant leak rates. |
| A simple calculation for tonnes of lost product can be determined utilising the latest market price for the product and provide a value for the actual loss. |
