# How are emission rates calculated?

## How are emission rates calculated?

Calculate the emission rate by multiplying the emission factor by the maximum capacity of the operation (in units of production per hour, material usage per hour, or whatever units the emission factor is in).

## What is the limit of suspended particulate matter SPM emission for stack monitoring?

What is The Limit of PM Emission For Stack Monitoring? As per CPCB or Indian standards for Industrial Stack Monitoring the flue gas emission from boiler stack, DG set emissions, the furnace should not exceed the limit for Particulate matter beyond 150 mg/Nm3.

**What is the emission limit of SOx from stack in mg Nm3?**

150 mg/Nm3

Therefore, an emission limit of 150 mg/Nm3 is adopted for the concentrator stack. Three products are formed in the smelter, namely, slag, metal and S02 bearing gases. Further refining is done in a converter.

**What is stack emission report?**

Stack Emission monitoring is often referred to the air monitoring of an emission point. Typically, such monitoring is carried out on boiler stacks, exhausts from printers, discharges from bag filters, thermal oxidisers and is performed on a regular basis.

### How is CO2 emission calculation?

The amount of inlet CO2 gas was calculated by multiplying the inflow rate of flue gas, infused into the CO2 capture and reaction facility, and the CO2 concentration. The CO2 in outlet gas was calculated by multiplying the CO2 concentration value and flow rate of the flue gas emitted from the facility.

### How do you calculate annual CO2 emissions?

Carbon dioxide emissions per therm are determined by converting million British thermal units (mmbtu) to therms, then multiplying the carbon coefficient times the fraction oxidized times the ratio of the molecular weight of carbon dioxide to carbon (44/12).

**What is minimum stack height?**

Stack Height Guidance At a minimum, the AQCD recommends all stacks for regulated emission points be at least four feet above the roof and that they not be equipped with any device that may obstruct the upward dispersion of the exhaust such as an old style rain cap.

**What is NOx and SOx emissions?**

The two main pollutants from the ship’s emission are Nitrogen oxides (NOx) and Sulphur oxides (SOx). These gases have adverse effects on the ozone layer in the troposphere area of the earth’s atmosphere which results in the green house effect and global warming.

#### What is stack height of DG set?

H = h+0.2 x √ KVA This is an explicit formula for DG SET stack height calculation, irrespective of the type of industries where the generator set is installed.

#### How do you calculate stack height?

Stack Height Calculation Stack height is calculated using following formula H = 14 (Q) 0. 3 H is height of Chimney Q = Quantity of fuel (kg/hr) x sulphur content (%) x 2 100 The sulphur content in the bagasse is negligible (around 0.1 %) as compared to Indian coal (maximum considered of 0.5%).
