Generic Process Flow Diagram - LEAD/LAG

Heliodor Solutions’ units remove hydrogen sulfide from process vapor streams.  The following information is required to design a system to meet your operational needs:

The composition of the influent gas stream and the final H2S requirement will determine the number and the size of the pressure vessels required. The simplest system is a single vessel with a gas inlet/outlet and a drain, without storage for chemical or spent solutions. The diagram above is an example of two vessels operating in a lead/lag configuration, with optional spent solution storage. A Process Flow Diagram can be designed to specific gas parameters, upon request.

Gas enters near the bottom of the primary vessel online and exits the top. The gas stream exiting the last vessel is monitored for H2S, which is easily accomplished using an online detection device or a drager tube. The H2S reading is used to determine when the chemical solution needs to be recharged.

Heliodor Solutions supplies the HS-1500 chemical solution and pressure vessels. The customer provides foundation, piping, pumps and instrumentation. Heliodor Solutions will monitor the system startup and initial operation and also train personnel to oversee continuous operation and to conduct chemical change out. We will provide quotes for the disposal of the spent solution, if required.
