Hi everyone, We are a solution mining facility to extract and evaporate brine to produce nacl (multi-effect evaporator). I have a question regarding the impact of CaCL2 and CaSO4 on produced salt purity. There are two scenarios: 1. Brine solution with CaCl2=0, CaSO4=5.6 g/l, the rest are nacl...

Hi Pierre, We are just trying to start up from shutdown this morning and unfortunately, the ejector broke performance. We ran a deadheaded test on the ejector: 1st suction: 0.93 inHgA. 1st stage discharge: 6.5 inHgA. 2nd suction: 3.61 inHgA and 2nd discharge to atmosphere: 0.46 inHg. Do you...

Hi Pierre, The valve is always open. When it closes, it is mainly for back filling the ejector system to check for leaks. Jordan

Hi Pierre, We bought a new spray nozzle and we will install the new one. Do you see any issue with the tailpipe arrangement from the inter-condenser? Jordan

We are performing our annual shutdown this week and I just took some pictures on the steam ejector. Do you see anything that is abnormal? Thanks, Jordan https://files.engineering.com/getfile.aspx?folder=eef5657b-6f3e-4ae4-8f06-872938e24be7&file=Air_ejector_2nd_stage.jpg

Hi Pierre, No feedback from Graham yet. Our annual shutdown is in 2 weeks, we will open up the inter-condenser and take a look inside. Thanks, Jordan

I attached a new trend of the steam ejector system, do you guys think the cause is still due to the scale/fouling of the inter-condenser? Unfortunately, our water wells are not able to provide the designed cooling water flow rate, we might be able to mix well water and lake water after some...

Sorry for the late reply. We opened the inter-condenser 2 months ago and it looked ok (not sure if there is any internal damage). As for the temperature profile, at the end of the video, the surface temperature jumped from 62F back to 72F around the area of vapor inlet. From what I have been...
