    • PROBLEM TO BE SOLVED: To provide a chemical plant which easily achieves scaling up of throughput of chemical process using a microreactor. SOLUTION: The chemical plant has a liquid sending line communicating with a raw material tank at a bifurcation of raw material and a means for detecting the flow of raw material, and a control valve for adjusting the flow located in the liquid sending line. In each branch line to each of the multiple microreactors connected in parallel, there are provided a means for monitoring the flow rate of raw material and a means for adjusting this flow rate. The quantity of the liquid to be sent through each control valve and each pump is adjusted by a computer while monitoring the flow rate of each liquid sending line to avoid the influence of air bubbles or deposits in each line and achieve stable liquid sending states.
