Dear All, I would like to seek opinion/feedback on the water draw off arrangement for the condensate stabilizer column. Please refer the attached sketch. In the Condensate stabilizer column, water draw offs are routed to separate Side vessel (top entry); the decanted water is removed via LV-200 from bottom. There is no liquid Hydrocarbon outlet provided. I am not sure whether this arrangement wil…

using activated MDEA + PZ solution for natural gas decarbonization, what is the typical packing height for common structured and random packings, such as Pall rings or 250Y structured packing? Also, where can I find or look up empirical HETP (Height Equivalent to a Theoretical Plate) data。

During ethane and naphtha cracking , which furnace is produce soft (for oxidation) coke . Ethane or naphtha? I am asking about coke deposition before decoking activity.

Dear friends, I am calculating the actual temperature of the flaring gas from our Vacuum Distillation Tower where a stream of gas (C11H24) at a temperature of 400 C, a pressure of 4.5 barg, enters a flare header with a diameter of 32 inches and a length of 600 meters. Given that the ambient temperature is 48 C , according to heat transfer calculations, on average, the gas temperature drops to 340…

HELLO EVERYONE, SO BASICLY WE WANT TO SIZE A PRESURE EQUALIZATION LINE FOR A 10" PIPELINE VALVE (KIND OF BY-PASS) TO EQUALIZE THE DOWNSTREAM OF THE 10" VALVE DE TO A VERY HIGH DP BETWEEN UPSTREAM AND DOWNSREAM OF THE VALVE. THE PIPELINE CARRY A 85 BAR LPG.

Hi everyone, I am designing a total condenser operating under full vacuum conditions. The process involves steam entering the shell side at 165°C and leaving as condensate. The tube side uses a process gas as a coolant (80,000 kg/h) in a U-tube bundle (2 passes). The exchanger is relatively "short and fat" (approx. 1000 mm length x 740 mm diameter), in BXU configuration. The main challenge is the…

I need to design a Concrete Thermal Energy Storage Tank with Slotted Diffusers The Process parameters are as follows Flow: 10700 usgpm (Fluid: Water) Temp in / out : 3.3 / 13.3 C Internal tank dimensions : 14 m x 14 m x 42.5 H There could be an H shaped or a octagonal shape diffuser with slots. The length of the diffusers (top and bottom) can be adjusted. I need advise from fellow engineers, if a…

Dear Team members, Instrument air dryer uses adsorbent  Alumina for removal of moisture designed for 100 % humidity & 45 Deg C  With lower humidity and feed temperature at 35 Deg C whats is impact on performance respect to dew point and capacity of the dryer. With regards

Dear Gents, In our product transfer unit TSV are provided on transfer lines from Tank to loading bay. TSV set pressures 12 bar are observed to match the pumps shut off pressure when operated at minimum flows.Now we need to reset the TSV set pressures,as observed frequent activation leading to maintenance.Whats should be the revised TSV pressure .considering no change in pump operation. Thanks
