Hi guys, Need some assistance on process design around a PHE I am looking to install. The HX serves to cool hot refined edible oil from 102 deg C to a nominal 45 deg C. The temperature of the outlet stream is not overly critical for any downstream processes, it is simply better for the quality...

Hi there, Am in the process of developing a design for new bulk caustic (50% NaOH) and sulphuric acid (98%) storage and handling systems.Both will be stored and distributed at ambient temperatures I am looking for a reference document that is useful to guide in the designs of these systems, or...

Hi all, I am currently half-way through the commissioning of a new vegetable oil neutralisation plant. We are having issues with high surging on a particular progressive cavity pump on the discharge of an oil vacuum dryer. The dryer vacuum pump is sized to hold 100mbar, and evaporates entrained...

Hi All, Looking for some assistance on a relationship/calculation to determine the caustic dosage rate required into a certain flow rate of acid water so as to neutralise it to a certain pH. If you refer to the attached sketch, it shows the parameters i am looking to get a relationship for...

Hi All, Looking for some guidance on the best materials to use for Sulfuric Acid pipework transfer, and diluted but low pH mixture. There are two operating conditions: 1) 98% Sulfuric Acid injection to a tank - ambient temp but tank is heated w/steam to approx 90-100 deg C therefore can...

Hi guys, With reference to the attached drawing from suppliers I have a vessel that is designed to retain oil and acid under pressure. The operating pressure is 6bar. The tank is bottom fed (supply line not shown) and discharged at height. On this discharge line you will see a safety valve, and...

Hi guys, Currently we are installing a process plant that features a closed hot water loop. There is effectively an atmospheric holding tank, that loads out directly to the suction of a centrifugal pump discharging to the various process applications. The flow in the supply line not...

Probably a pretty simple question for you guys. A supplier designing and installing a low pressure (3barg) steam line for a refinery plant has specified schedule 10 pipe work. The extent of their design currently is that schedule 10 is pressure rated > 3barg, with no calcs in alignment with any...
