flaring means to removes extra gases from system to keep
system pressure in safe condition

Answer / murthy

flaring is burning of excess gases in safe area away from
plant.these can observed in almost all
petrochemical/petroleum refineries/power plants/steeel
plants wherever hydrocarbon gases which form explosive
mixtures are used.this is done due to many reasons
(1) excess gas production than requirement of downstream
plants
(2)sudden tripping of consumers i.e downstream plants
(3) gas not meeting standards required by customer i.e
downstream plants
(4)unwanted pressure increase in pipelines conneting
customer and supplier
(5) stopppage equipment like compressors,blower.
(6)even when there is pipeline leaks,gas is routed to
flares.

Answer / pradip ramoliya

Some times in refineries interconnected plant's. So, any
plant in abnormal condition that time effected to other
system and the pressure of system is abnormal. So extra
pressure and unuseful gases are remove from system for
normal condition and gases go to flare and combustion them.
That called flaring

Answer / gauravtrivedi

it is the safe and efficient disposal of relifed gases by
burning to prvevt overprssuring the equipments in plant.

Question 57 – There are 2 simultaneous equations : (A1) x + (B1) y = D1 and (A2) x + (B2) y = D2. (a) By using Excel program, find the values of x and y when A1 = 80, A2 = 150, B1 = 52, B2 = 100, D1 = 3.5 and D2 = 2.3. (b) Write the expression of Excel in the form of =MMULT(MINVERSE(W:X),Y:Z) in order to get the values of x and y. W, X, Y and Z may be A1, A2, B1, B2, D1 and D2.

ACCOUNTING AND FINANCIAL ENGINEERING - EXAMPLE 34.12 : You, as an engineer, buy a piece of biochemical instrument to start a servicing business. The instrument has a useful life of 3 years, that costs $60k. The instrumental business generates $100k per year. The labor costs $50k per year. The $60k new instrument depreciates in its value evenly up to 3 years, thereafter the old instrument needs to be replaced by another piece of new instrument. (i) In the first year of this engineering business : (a) what is its starting cash? (b) calculate the depreciation value of the instrument. (c) find the operating profit generated. (d) what is the capital expense of the business? (e) calculate the cash from operation. (f) calculate the ending cash. (ii) Based on the income statement of the business in the second year : (a) find the capital expense of the business. (b) what is its starting cash? (c) calculate the depreciation value of the instrument. (d) find the operating profit generated. (e) calculate the cash from operation. (f) calculate the ending cash.

Question 38 - The terminal velocity of a falling object, v is given by v = sqrt [ 4g (R - r) D / (3Cr) ] where sqrt is the square root of, g = 9.81, D = 0.000208, R = 1800, r = 994.6, m = 0.000893. The Reynold number, L is given by L = rD (v) / m. The C for various conditions are : C = 24 / L for L < 0.1; C = 24 (1 + 0.14 L^0.7) / L for 0.1 <= L <= 1000; C = 0.44 for 1000 < L <= 350000; C = 0.19 - 80000 / L for 350000 < L. Find the value of v for the situation above by trial and error, ^ is power, <= is less than or equal to.
