On July 3, 2022, Haiyuan chemical production was normal, mainly supervising the formaldehyde unloading operation, the normal production of propargyl alcohol and 1,4 butynediol finished products, and the inspection of the workshop in the centralcontrolroom.
Supervise the formaldehyde operation during the day, and urge the implementation of relevant safety supporting facilities such as operators' non departure, electrostatic grounding, sliding sleepers, emergency shut-off valve inspection, emergency equipment, etc.
Central control room Patrol: patrol the central control room of major hazard sources such as propargyl alcohol, 1,4 butynediol tank farm and formaldehyde tank farm to ensure that all indicators are normal.
Operation of each workshop:
Gas supply workshop
1. The pressure of the gas reservoir in the gas making workshop is 3.69kpa, and the operating temperature of two sets of generators A and B is 75-78 ℃.
2. The total amount of crushed calcium carbide particles used for mixing in the day shift is 86.7kg, and the screened calcium carbide powder is 135kg.
3. Water is exposed at the root of the weld crater of the outlet pipeline of the North slurry pump in the gas plant (where the clip was originally made), and continue to adjust the angle to make the clip.
Synthesis workshop
1. The activation solution of activation kettle A is pumped into a set of system
2. Activation of activation solution of activation kettle B ends at 20:50.
3. PH value of liquid alkali in alkali Tower: 13.33
PH value in front of alkali Tower: 6.36
PH value behind alkali Tower: 7.51
PH value of purifier: 12.52
4. The acetylene supply content in the synthesis workshop is 90%, and the return gas content is 74%
Refining workshop
1. Content of butanediol extracted from diaphragm Tower: 65.7%, pH value: 5.54, conductivity: 1237, temperature: 25 ℃.
2. The methanol receiving temperature of the dealcoholization tower is interlocked at 73.5 ℃, and the content of propargyl alcohol in methanol measured is 0.8
3. Ammonia water added into diaphragm tower in day shift: 45L, opening of ammonia dosing pump: 15%, frequency of frequency converter: 100%, pH value measured by pH meter: 9.2
4. The feeding opening of diaphragm tower in refining workshop is 100%, and the flow is 10.7m ³/ h. The flow is low, and the pneumatic valve of the main line shall be disassembled and inspected. And start the auxiliary line adjustment operation.
5. The oil and gas separation storage cup of the pressure regulating valve at the bottom of the first tower in the refining workshop is aging and leaking. It is replaced and put into use.
6. Dismantle and inspect the diaphragm tower feed flowmeter in the refining workshop, and stop the ammonia dosing metering pump,
Sewage treatment workshop
1. Circulating water temperature: 31 ℃, open four cooling tower fans
Pay attention to the normal operation of DCS and APC.
Haiyuan chemical has always been strict in safety production management and done a solid job in safety production.
