This post was last edited by Green Lotus on 2018-9-8 at 17:05. [Q&A Question 245] 2018.09.08: Briefly describe the locations in a hydrogenation unit where angle valves are commonly used. High-pressure control valves, compressor outlet valves, cold hydrogen control valves, two-in-one valves, high-pressure liquid control valves, and high-pressure level control valves. This is because angle valves can withstand large pressure differences, serve to reduce pressure, and offer good safety features. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Correct: 3 wealth, Incorrect: 1 wealth ； Mass posting of posts – rated based on the lowest score ； Replies that are unrelated to the answer are considered spam and will be deleted immediately.

Compressor multi-return one-way valve (two-return two, four-return one), heat separation liquid control valve, cold high-pressure separation control valve, cold high-pressure liquid control valve, angle valve for the outlet of the desulfurized and amine-enriched liquid from the circulating hydrogen system, angle valve for waste hydrogen discharge, angle valve for the minimum flow line of the reaction feed pump, drain valve of the liquid separation tank located in front of the circulating hydrogen desulfurization tower, and drain valve of the liquid separation tank located in front of the circulating hydrogen compressor. Valves on the minimum flow line of the feed pump, make-up water pump, and lean solution pump feeding the hydrogen circulation desulfurization tower; the minimum flow line of the hydrogenation feed pump; the return line of the make-up water pump; the control valve for adjusting the flow from high-pressure to low-pressure; the control valve for sending high-pressure acidic water outside; the three-return-one-control valve of the new hydrogen compressor. The drain line of the liquid separation tank in the compressor room is also equipped with a corner valve.
Compressor multi-return one-way valves (two-return two, four-return one), heat separation and liquid control valves, cold high-pressure separation control valves; liquid control valves for cold high-pressure systems, angle valves used in the hydrogen circulation desulfurization and amine enrichment process, angle valves for waste hydrogen discharge, as well as angle valves for setting the minimum flow rate of the reaction feed pump. Angle valves can withstand large pressure differences, thus serving a pressure reduction function and offering good safety features.
