Liquid Phase Dechlorination Agent
1.Liquid phase dechlorination agent is a unique dechlorination agent for products made from liquid phase naphtha oil.
2.It adopts the catalyst carrier and catalyst prepared by a unique process.
3.It is produced to remove hydrogen chloride.
Product Introduction
Depending on the raw materials and operating conditions, liquid phase dechlorination agent is produced to remove hydrogen chloride, ammonium chloride, and organic chloride from process raw materials.
It is a unique dechlorination agent for products made from liquid phase naphtha oil. The dechlorination agent uses a catalyst carrier and catalyst that have been specially formulated along with other ingredients. It has a lot of chlorine capacity, excellent dechlorination precision, immersion resistance, and strength. The liquid phase dechlorination agent can be used for the fine dechlorination of straight run naphtha, secondary processed naphtha, C5, C4, and liquefied gas.
Process Flow:
The reformed oil is pumped from the bottom of the liquefied gas absorption tank and pressurized.Heat exchange to 91°C through a depentanizer feed/bottom heat exchanger,entering into the depentanizer feed dechlorination reactor.The chloride in the reformed oil is removed after being adsorbed by the liquid phase dechlorination agent.And the reformed oil after the dechlorination treatment enters the depentanizer after being fed into the second-stage depentanizer/heat exchanger at the bottom of the tower.Override controls for pressure, level and flow at the outlet of the dechlorination reactor.The purpose is to make the dechlorination always be carried out under a certain pressure, to ensure that the flow rate of the dechlorination reactor is stable.The dechlorination reactor is always in a state of liquid phase full of liquid.

The PID design is basically the same as the setting of conventional gas phase dechlorination adsorption (such as hydrogen dechlorination system).Take the operation mode that can be connected in series or in parallel.The main difference is that since the reformed oil dechlorination system is liquid-phase adsorption, in order to ensure the adsorption performance of the liquid phase dechlorination agent, it must be filled with liquid at the start-up stage, and a liquid-filled line with a sight glass is added.
