Hydrogenation startup water interconnection

2018-07-03View Original

Thread Content

When operating in conjunction with water, should the feed system be connected to the distillation system to operate together with water, or do they circulate separately? I hope the experts here can give some advice

If it’s possible to connect them in series, that’s best; if not, let them operate in parallel

Feeding water into the reaction system? Are you joking~~~ The distillation system should be washed with water separately; use water for transportation~~
Reply #42018-07-03
The reaction systems are not connected; there is a line from the outlet of our feed pump to the fractionation tower. We are considering whether it’s possible to connect them together

The reaction feed pump also undergoes individual water testing. With such a high outlet pressure from the feed pump, is it sent directly to the distillation process? I’ve never seen a reaction feed pump used in the water testing for distillation processes~~~

Water interconnection refers to the distillation system, or distillation sub-circuit; during initial startup, it can be equipped with a crude oil tank and a feed pump (for single-unit testing at minimum flow rates);

The purpose of water transportation is to use water to carry oil, in order to test the performance of various moving and stationary equipment, instruments, control valves, etc. The disturbances caused by water are also utilized to remove impurities from the equipment and pipelines (which generally accumulate at the bottom of containers or at the inlet of pump filters). By involving as many pieces of equipment as possible in this water-based transportation process, it becomes possible to detect and address issues such as leaks and equipment failures early, thereby avoiding the significant risks that can arise from problems during oil transportation. Therefore, apart from the reaction system, other components such as the feed system and the distillation system should be transported by water whenever possible. In practice, the feeding system and the diversion system can be transported by water separately, or they can also be transported together by water. If it is the first time that the facility is put into operation, it is recommended to use both methods. After all, the shipping time for the first start-up is relatively long, so there is enough time; trying out various methods serves both as a way to test the equipment and as an opportunity for training, allowing everyone to become familiar with the operations.

The feed pump also needs to be considered carefully; if you’re using diesel or an even lighter oil, then you need to be cautious. Water has a high density, and in addition, a low back pressure at the outlet can lead to overcurrent, posing safety risks. If it’s something like paraffin oil with a similar density, then there should be no problem with the current. :handshake

I only knew that a low-pressure pump can’t operate when its head pressure is too high; it’s the first time I’ve heard of a high-pressure pump being unable to generate low pressure… Are you worried that a low back pressure might lead to excessive current flow? What electricians consider when looking at current is that with media of similar density, there are generally no major issues. As the flow rate increases to its minimum value, the electrician sees that there is no problem with the current……

The feeding system does not require water for operation; it is not possible to separate the reactor, and water cannot be introduced into the reactor
